Act Quickly: The Essential Guide to A2L Refrigerants
▸ June 14, 2024

In the ongoing effort toward environmental sustainability, a pivotal shift is underway that will reshape the landscape of HVAC systems. A2L refrigerants are set to revolutionize how we cool and heat our spaces, but their adoption comes with an important deadline. As conscientious consumers and forward-thinking business owners, understanding this change is not just beneficial—it’s necessary. HVAC systems and their refrigerants have a significant influence on our environmental impact, making the transition to A2L refrigerants both a challenge and an opportunity of great significance. 

Understanding A2L Refrigerants

A2L refrigerants represent a significant advancement in the realm of refrigeration technology. But what exactly does the term “A2L” signify, and why is it garnering attention in the HVAC industry? A2L refers to a classification of refrigerants characterized by their lower toxicity levels and reduced Global Warming Potential (GWP). These refrigerants have been mandated by governments worldwide as part of efforts to mitigate the environmental impact of HVAC systems. Unlike the refrigerants before them, which often contained harmful substances with high GWP, A2L refrigerants offer a more environmentally friendly alternative. The significance of A2L refrigerants extends beyond just compliance and regulations. They represent a proactive step towards creating a safer and healthier planet for future generations. By minimizing the release of harmful chemicals into the atmosphere, A2L refrigerants contribute to the global initiative to combat climate change and preserve the essential balance of our ecosystems.

How Does A2L Affect You?

As regulations regarding refrigerants continue to evolve, it’s crucial for businesses and individuals to understand how these changes will impact them. For owners of older HVAC systems, the transition to A2L refrigerants may necessitate more than just a simple refrigerant replacement. Unlike past phase-downs of refrigerants, which often involved retrofitting existing equipment, A2L refrigerants require a shift towards new, specialized equipment designed to accommodate their unique properties. This shift poses both challenges and opportunities for stakeholders in the HVAC industry. While the initial investment in new equipment may seem daunting, the long-term benefits in terms of energy efficiency and environmental stewardship are undeniable. By embracing the transition to A2L refrigerants, businesses can not only stay ahead of regulatory requirements but also position themselves as leaders in sustainability.

The Role of Preventative Maintenance

When embracing A2L refrigerants, the importance of preventative maintenance cannot be overstated. HVAC equipment, if not properly maintained, can become a major contributor to environmental degradation. Aging systems, combined with a lack of timely maintenance and repairs, can lead to the release of harsh refrigerants into the atmosphere. One of the key factors driving the transition to A2L refrigerants is the need to address the inefficiencies and environmental impact of outdated HVAC systems. Neglected equipment not only consumes more energy due to decreased efficiency but also poses a greater risk of malfunction and leakage. In a time of rising temperatures and heightened environmental awareness, the need for sustainable HVAC solutions is important.

Understanding the Regulatory Change

Effective January 1, all equipment manufacturers will transition to A2L equipment production, meaning you will no longer be able to purchase new units with 410(a) refrigerant. This shift is reminiscent of the phaseout of R-22, which led to significant price increases and much longer lead times for equipment. While refrigerant and parts for 410(a) equipment will still be available, it is crucial to consider the implications of this regulatory change.  To mitigate potential disruptions, it’s advisable to explore your options for ordering equipment now, before the mandated transition. By acting promptly, you can avoid the anticipated cost hikes and supply chain delays associated with the widespread shift to A2L refrigerants. Our team at BMI Mechanical is ready to assist you in navigating these changes, ensuring a smooth and efficient transition for your HVAC systems.

What Should You Do?

In light of these developments, it’s important for businesses and individuals to take proactive steps toward understanding and adapting to the transition to A2L refrigerants. This begins with asking questions, conducting research and seeking guidance from knowledgeable experts in the field. BMI is here to assist you in navigating this transition, providing you with the expertise and support you need to make informed decisions regarding your HVAC systems. At BMI Mechanical, we recognize that our own Green Initiatives drive our commitment to technological advancements and sustainable practices. Just as regular maintenance is essential for the health of our planet and our bodies, it is also vital for the longevity and efficiency of HVAC equipment. By prioritizing preventative maintenance and embracing the transition to A2L refrigerants, we can create a more sustainable future for generations to come. The emergence of A2L refrigerants represents a big milestone in the journey toward environmental responsibility in the HVAC industry. By understanding the importance of A2L refrigerants and prioritizing preventative maintenance, and with the support and expertise of BMI, you can navigate the transition to A2L refrigerants with confidence, knowing that you’re taking proactive steps towards a greener, more sustainable future.

hvac standards post graphic
▸ September 7, 2022

Starting on January 1, 2023, the U.S. Department of Energy will raise its HVAC efficiency standards by 7%. Due to the increase, HVAC manufacturers must retool their plants to make new units that meet these standards. The pending regulatory change significantly impacts HVAC equipment availability and pricing.

What’s the Impact?

Since early summer, manufacturers have stopped building old-style units to prepare for the upcoming standard change. HVAC units are becoming increasingly scarce, with inventories steadily dwindling throughout the season. With a lead time of over 20 weeks to receive even simple package equipment, we don’t expect to receive equipment orders until at least February or March. 

What are the Options?

As we wait for manufacturers to build 2023 efficient units, here are some options available to customers needing equipment installed or replaced:

  1. BMI Mechanical will try to find a unit that will work using available inventories. In some situations, we’re able to find close matches that can be modified in the installation.
  2. Customers can change the design to a ductless split system or a variable refrigeration flow split system. Since the systems are modular, multiple small units could handle larger applications. These technologies also already meet the 2023 energy efficiency standards, so there are no supply issues or lengthy lead times.
  3. Customers can approve package unit replacements now and receive the ordered equipment in 2023. Units will not arrive until February or March, but at least customers will have locked in the lead time and price (we expect prices for this equipment to increase significantly after January 1.). 

At BMI Mechanical, we want our customers to be aware of this issue. For customers considering purchasing a new package unit, we advise them to contact us now to get ahead of the supply issues. For customers that already have a proposal from BMI for a unit installation or replacement, we advise them to check the proposal date since our proposals are only valid for 30 days. 

Want to Avoid Equipment Delays?

Customers can also avoid supply issues with BMI’s proactive preventative maintenance. Our proactive preventive maintenance helps extend equipment lifetime and identify issues before they cause extensive equipment failures and unexpected damages.

If you’re a building manager or owner, it’s likely that you know a rough estimate of how much you spend on repairs, maintenance, and service for your HVAC system.

Depending on the status of your HVAC system, these necessary costs can run up quite the tab. And unfortunately, the expenses don’t stop there.

We’ve laid out 5 additional costs to owning and operating your HVAC system.

In-house Staff

Maybe you manage a multi-tenant building. If this is the case, it’s likely that you have an employee who spends a portion of their workweek listening to and addressing tenant concerns. Some of these concerns probably overlap with your HVAC system.

At the end of the day, this boils down to time. 

How much time has your employee (or employees) spent dealing with these issues, and what does that equate to in total payroll costs? This could easily end up costing your business hundreds, if not thousands, of dollars every year.


Let’s say you do have an HVAC system that’s more needy than others. This could mean that your employees are regularly encountering HVAC issues and hunting down contractors, bids, invoices, project contracts, appointments, and more.

Again, how much time does this take from your employees and how much is costing your business in payroll every year? And what better activities could your employees be focusing on? Activities that could be making you money as opposed to spending it… 


If your building can’t maintain the appropriate temperature and struggles to preserve good indoor air quality, your employees or tenants will be uncomfortable and less productive. This is a fact and is among the top concerns of office workers.

A survey shows that heat and cold are the top two complaints for office workers. And studies prove what is a matter of common sense to most employees: if it’s too frigid or steamy, you are not going to be able to get as much done.

We all know that a loss in productivity means a loss in time and money. But exactly how much time and money does this mean for your business?


Unsurprisingly, one of the top money wasters of HVAC systems is energy. If you’re attempting to operate and maintain your HVAC system in-house, then you may not have direct access to someone who understands how to minimize energy waste. 

There’s a lot that goes into this component — from updates to automation to reporting. If you’re not careful and if you’re not on-the-ball, you could be spending considerably more money than you have to spend.

Capital Avoidance

For a true annual cost analysis, you need to factor in the annualized cost of future replacement for your HVAC equipment. This requires an analysis of age, condition, and current replacement costs

If you’re not factoring this into the total cost of owning and operating your own HVAC system, then you’re going to be in for a big surprise at some point in the future. For many building owners and managers, this point often comes much sooner than they realize.

Do you need help understanding the total cost of your HVAC system?

Give us a call or send us a message today. At BMI Mechanical, we’ve spent the last several decades helping companies all across the West Coast better understand, operate, and maintain their HVAC system. As a result, we’ve helped them save money and create a better indoor environment for their tenants and employees.

office building for rent keep tenants
▸ August 28, 2021

If you own or manage a multi-tenant commercial property, then one of your primary objectives is likely to improve tenant retention.

Losing tenants is very expensive. Not only will you lose rental income, but you’ll also have to spend money to attract new tenants and clean and renovate empty rentals. 

In the long run, it costs way more to lose and find new tenants than it does to invest in ways to maintain tenants.

This involves a multi-pronged approach; however, one area that many building owners and managers fail to consider is their HVAC system. Let’s talk about why your HVAC matters.

Why do tenants care about the HVAC system?

There are a variety of reasons tenants would care about the HVAC system in place. The top 2 reasons, however, would involve comfortability and indoor air quality.

If your HVAC system isn’t capable of handling your tenants’ heating and cooling requirements, you can almost guarantee a regular stream of tenant complaints. And with the emergence of COVID-19, many tenants are also concerned about indoor air quality. If you’re not doing anything to properly ventilate and sanitize your building, tenants may start to question if your building is the right building for them.

Does any of this sound familiar? If so, keep reading.

How to improve your HVAC system for your tenants

At BMI Mechanical, we’ve spent the last several decades helping multi-tenant buildings improve and maintain their HVAC systems. As a result, we’ve also helped improve their overall tenant retention rates. Let’s address the 5 most effective ways we accomplish this.

  1. Automated Systems: We work with our clients to integrate modern technology into their buildings. While this sometimes involves a complete overhaul of their pre-existing HVAC system, many times it involves something as simple as programmable thermostats and a building controls upgrade. This gives everyone greater insight and control over the HVAC system.
  2. Minor Upgrades: Again, many of the ways we improve our clients’ HVAC systems involve minor upgrades to pre-existing equipment. These changes could include duct modifications or equipment add-ons.
  3. Regular Maintenance: Partnering with an HVAC partner for regular HVAC maintenance is probably the best (and easiest) change you can make. Regular maintenance will provide you with a slew of benefits, and you’ll be more capable of avoiding complete breakdowns.
  4. Improved Filtration: Not every system can handle the highest level filters; however, you can fight COVID-19, other viruses, and seasonal allergies with additional measures (like in-room air purifiers, UV, and NPBI). This added level of protection will keep your tenants healthier and give them more peace of mind.
  5. Inform Tenants: When you make improvements and even when your ongoing maintenance appointments roll around, make sure you let your tenants know what’s going on. If you don’t, then they may never realize that you’re taking steps to improve their experience. Print out memos and hang it around the building or send out an email blast to your tenants.

When you work to improve your HVAC, what you’re really doing is working to improve the comfortability and health of your employees. 

Poor HVAC management can impact your employees in a variety of ways. 

If you struggle to maintain your equipment, it could result in an uncomfortable indoor environment — which can lead to employee complaints and a decrease in employee productivity. And if your HVAC equipment struggles to maintain a good IAQ (indoor air quality), it could result in heightened risks — such as virus transmission, seasonal allergies, and more.

To help you better understand this, let’s dig into what can impact IAQ and indoor comfortability.

What impacts IAQ?

There are many different factors that can negatively impact your building’s indoor air quality. But fortunately, with the right equipment and measures put in place, you can control the level at which these factors impact your environment.

Let’s break this down a bit more.

  1. The Outside Air: It’s only natural to assume that allowing outside air to flow into your building is a good thing. But that’s not always the case. While “fresh” air is naturally brought inside via doors and windows, your HVAC system also brings in outside air. It’s important to set up your HVAC properly, so you’re not bringing in too much outside air and overloading your equipment in the process. You should shoot for a level between 10% and 20%.
  2. Your Filtration Method: Another thing many people assume is that a higher filtration method is better. But again, this isn’t always the case. MERV 13 is currently recommended by the CDC and ASHRAE to capture smaller particles in the air; however, every system is not capable of handling this higher level of filtration. If you utilize a MERV 13 filter on the wrong system, you could end up damaging components. Instead, MERV 7-10 may be better suited for your system — while still providing a good level of filtration. You can always use additional methods of sanitization to make up for the lower-rated filter.
  3. Your Sanitization Technology: If you have outdated (or no) method put in place to sanitize your indoor environment, then you’re likely working around small particles that reduce your IAQ. It’s important to work with a licensed HVAC contractor who can educate you on modern sanitization technologies (such as NPBI) that are capable of targeting and capturing smaller particles in the air.

What impacts employee comfort?

Obviously, a poor indoor air quality can negatively impact your employees. It can lead to a higher transmission of viruses, as well as promote an environment that’s well-suited for allergies. This can result in decreased productivity and an increase in sick days. 

Aside from IAQ, however, there are many other factors stemming from your HVAC’s performance that can negatively impact your employees. Let’s take a look at some of those factors now.

  1. Reliability: If your HVAC struggles to work consistently, then you stand the risk of it breaking down during peak hours. This could create big productivity issues for your company, especially if these breakdowns occur during very cold or hot days.
  2. Controls: It’s important to make sure your equipment is on the correct “schedule.” Does your equipment turn on and off at the right times? If not, your employees might be subjected to a very hot and stuffy working environment. While it may only take a little while for the environment to get to a comfortable working temperature, all of your employees will be a little (or a lot) less productive during that time period. 
  3. Air Flow: Too much or too little air flow can also impact indoor comfortability levels. Air flow can be hampered by windows, furniture, office equipment, and more. Adjustments can vary from one building to the next, but often involve a simple damper adjustment or duct modification. Either way, it’s best to speak with a licensed HVAC contractor, so they can educate you on the best solutions for your unique needs.
  4. Hot & Cold Spots: Even if your equipment is working properly, there may be sections of your building that suffer from hot or cold spots. If your employees work near these areas for extended periods of time, it can become problematic. 

Do you need help improving your indoor environment?

Air quality and employee comfort can have huge and lasting impacts on your business. In fact, according to the National Energy Management Institute, the cost of low employee productivity due to comfort and air quality issues is 1.5-3% of annual payroll costs.  

While there is no such thing as a perfect building with 0% lost productivity, there are many steps you can take to get your indoor environment to a healthy and comfortable level. And at BMI Mechanical, we’ve spent the last several decades helping our clients do just that.

humidity levels bmi mechanical
▸ August 10, 2021

Whether you live in Florida or California, we should all shoot to maintain normal indoor humidity levels.

But what exactly is considered “normal” indoor humidity levels and why is it important?

Let’s break it down.

What is a normal indoor humidity level?

A normal (or ideal) indoor humidity level would be somewhere between 30% and 50%.

A 30% humidity level means that the air is holding 30% of the total amount of moisture it can contain.

There are certain factors that can increase or decrease your humidity, including the outdoor environment and your air conditioning equipment. It’s also important to remember that humidity is crucial, and with too little of it, you can experience just as many issues as you would with too much of it. In other words, the goal is not to shoot for 0% humidity.

Let’s go ahead and dissect this a little further by discussing symptoms of low or high indoor humidity levels.

Symptoms of high humidity in home or office environments

  1. You’ll feel warmer! (And maybe even a little sticky!)
  2. You may create a comfortable environment for fungus, dust mites, mildew, mold, and bugs — which could make you sick and negatively affect people with asthma, allergies, or sinusitis 
  3. Too much humidity can also negatively affect wood, which can cause wood to rot and furniture to warp.

Symptoms of low humidity in home or office environments

  1. Similar to symptoms of too much humidity, too low humidity can negatively affect people with asthma and other breathing-related issues (since the air is too dry).
  2. Air that is too dry can lead to chapped lips, sore throats, and dry, itchy skin.
  3. Humidity that’s too low can also cause wood to warp or crack. This is because there is no moisture in the air and the wood literally shrinks.

What to do if the humidity is too high or too low

If you start to notice any of the above symptoms, make sure you take the proper steps to test your humidity levels. You don’t want your family or employees struggling to breath or suffering from sinus-related issues due to a problem that is relatively easy to address.

While there are tools you can use to test the humidity levels of your home or office, it’s best to contact a professional. This way, they can give you accurate guidance on your humidity levels, and you can avoid wasting money on solutions that don’t address the actual issue.

This being said, if the humidity is too high, you may need to replace your air conditioner. This is usually only necessary if the unit or parts are too old and can not effectively remove the humidity from the air.

If this is not an option for you right now, a dehumidifier may temporarily help resolve the issue. There are many different options and sizes available (all of which address different needs), so it’s best to speak to a professional to find out what works best for you.

On the other hand, if the humidity is too low, you can seek out a humidifier. If the issue is just with one area of the house or one office in a commercial space, a portable humidifier may solve the issue quickly. However, these do require some regular upkeep to continue working, and they will be severely limited in reach. 

If you do require a larger, more professional humidifier, it’s important to speak with a professional who can give you guidance on selection, installation, and maintenance.

Many businesses make the decision to go for the gold in green building initiatives and get LEED or ENERGY STAR certified. 

Becoming certified is great for a multitude of reasons — more productive employees, less waste, better optics, and more. However, certification is not your only option.

You don’t need to be certified to practice and enjoy green building initiatives. Let’s take a look at some of the various measures you can implement right now, so you can create a greener building.

Plan ahead for equipment replacement

Aging equipment that doesn’t work as well as it once did can become problematic. This equipment can (and likely will) consume more energy to work and cost more money to repair. 

This is why it’s imperative to plan ahead and create a sound strategy for equipment replacement. BMI can help with this.

We’ll go into your system, evaluate its current standing, quantify these items, and determine viable options for future replacement — including like-for-like replacement, hi-efficiency models, and more.

On top of this, we’ll provide you with creative financing solutions for such costly investments. This way, you can truly plan ahead for these necessary improvements and proactively keep your business above water.

Implement building automation

Whether you decide to go with building-wide automation or just WiFi-enabled thermostats, any amount of automation can help your business go a little greener.

At BMI, we can help you implement a number of systems (or recalibrate and improve existing systems) to automate your building. In the process, we can help you cut down on waste and control costs.

Integrate preventative maintenance into operations

Preventative building maintenance is a key component of any business. 

When you rely on your building to keep your staff comfortable and your operations consistent, then you need to make sure all of your building’s equipment is properly cared for. 

On top of this, failing to maintain your equipment will result in more waste (both in terms of energy and being forced to replace equipment too early).

Preventative maintenance can involve a variety of components, including regular inspection, computerized scheduling, consistent documentation, and more. These tasks can save up to 30% in energy costs, reduce annual repair costs, and prevent downtime.

Athletes aren’t the only ones going for the gold this season. At BMI Mechanical, we’re helping our clients go for the gold, too. 

But not in the traditional sense. 

Rather than gold medals, we’re helping our clients achieve a gold standard in energy conservation and sustainability through a LEED building rating.

LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world. Available for virtually all building types, LEED provides a framework for healthy, highly efficient, and cost-saving green buildings. LEED certification is a globally recognized symbol of sustainability achievement and leadership.

LEED certification is available for both new and pre-existing buildings (no matter what age the building is) and ultimately, helps buildings reduce their environmental impact and become more energy efficient. 

Let’s take a few moments to cover what the benefits of LEED are and how your business can pursue LEED certification. 

What are the benefits of LEED certification?

Aside from simply conserving energy and reducing your building’s environmental impact, there are many additional benefits of pursuing LEED certification. Let’s address those now.

  1. You can become more competitive and differentiate yourself from the competition. “Going green” is considered a positive and could play a role in purchasing decisions from your target market.
  2. A building that reduces waste and saves energy is typically more attractive than a building that doesn’t. If you’re leasing out spaces to renters, this means you could charge more — or at the very least, use it as a selling point.
  3. With a better-managed and greener building, it’s only “natural” that you’ll benefit from a better indoor (and outdoor) environment. This will lead to happier and healthier employees and occupants, which can improve productivity, retention, and more.

How to work towards LEED certification

When attempting to pursue LEED certification, it’s best to work with a qualified partner like BMI Mechanical. There are a variety of categories that must be addressed and standards that must be met in order to qualify. Without a knowledgeable partner, this process will be much more difficult (if not impossible) to work through.

Specifically, BMI Mechanical can help your business with design, equipment selection, installation, and maintenance practices. All of these facets earn you “points” — which ultimately decides your rating. Your rating can be anything from certified (lowest) to platinum (highest). Points earned can vary drastically based on how your building performs, what types of materials your building is using, how your building uses energy, and more.

Not interested in LEED certification? Consider pursuing ENERGY STAR certification. This process achieves similar goals (emitting less, saving more money, reducing waste), but it’s focused on energy performance standards that are set by the EPA. However, this certificate is renewed every year — which means standards must be maintained.

Are you ready to go green? Contact BMI Mechanical.

At BMI Mechanical, we have decades of experience helping companies everywhere reduce waste, save money, and go green, and we’d love to help you, too.

We can help you better understand the rules and standards set forth by LEED and ENERGY STAR, make changes to your building and maintenance practices, and collect and report on the appropriate data.

Your HVAC system does a lot of good for your business. It keeps your guests and employees comfortable, productive, and healthy. But unfortunately, there are several facets of your HVAC system that can create hurdles and complications for you — regulations and reporting requirements are prime examples of those hurdles.

To further break this down, let’s discuss some of the reporting and management requirements and provide you with guidance on how to remain compliant with them.

Refrigerant Management

Refrigerant is an ozone-depleting substance that can be harmful to the environment. As of late, R-22 refrigerant has been in the process of phasing itself out. As a business owner or manager, it’s important for you to keep up with updates such as this one. Otherwise, you could face fines and regulatory shutdowns.

On top of this, you’re also required to maintain regular and detailed reporting on refrigerants. This includes leaks, type, levels, dates, and more. If you fail to keep up with reporting, this could create serious regulatory hurdles for your business.

When you work with an HVAC company like BMI Mechanical, they’ll constantly collect and maintain all information pertinent to your system. At BMI, we gather all this information and use it to generate reports on their behalf, helping them maintain compliance in the process.

Boiler Emissions & Air Quality

When it comes to the usage of large boilers, you’re required to abide by regulations at both the statewide (California Air Resources Board) and local (County Air Pollution Control District) levels. Specific emissions produced by these boilers must be measured and reported annually. If they do not meet the acceptable limits set by the state and county, then repairs or replacement are required.

Working with a commercial HVAC company eliminates this hurdle and simplifies the entire situation. At BMI, we have specialized testing and reporting services available to help our clients with this particular regulatory concern.

HVAC companies can also help you with seasonal shutdowns. Read our 3-part guide on seasonal HVAC shutdowns.

Air Change Rates

Depending on your business environment, you may be held to different regulatory standards — this includes healthcare facilities and ACH (air changes per hour) rates. When you’re talking about ACH, you’re talking about the number of times air is cycled in a room within a specific period of time.

The required ACH varies by business and in some cases, by room. It is impossible to measure the ACH rate without specialized equipment and skills. This is why it’s important to work with an HVAC company who can take this regulatory concern off your plate. They’ll also be able to work this into regular service testing, so it is always reported accurately and keeps your business in the clear at all times.

neon sign shaped like a question mark
▸ July 7, 2021

Many people want to know, “How often should I change my air filter?” 

Does it really make a difference if I replace it once every 6 months as opposed to once every 3 months?

The answer to this question is yes. It does make a difference, and here’s why:

  • You can reduce repairs: Your air filter collects a lot of things over time (pet dander, dirt, etc), and it usually turns “dusty” or “grey” as a result. If you allow your filter to be dirty like this for long periods of time, it can have a negative impact on your HVAC and its components. This will ultimately lead to more repairs (and more bills).
  • You can save money: Yes, you can save money on repairs by doing an air filter change at the right time, but you can also save money on your heating and cooling bill. Your HVAC won’t be able to work properly with a dirty air filter — instead, it has to work much harder. You can guarantee that this hard work will be showcased in your next energy bill.
  • You can improve your IAQ (indoor air quality): Whether you have allergies or not, it doesn’t matter. If your air filter can’t do its job properly, you’ll eventually be breathing in a whole lot of stuff that’s not great for your body. 

Now that we better understand why it’s important to change out the air filter, let’s talk about how often to change the air filter.

How often should you change your air filter?

There are a handful of factors that can impact the question of how often to change the air filter. These factors will vary from home to home and from business to business. This ultimately means that every building should be doing an air filter change at different times.

If you’re in a commercial or industrial setting that requires a more particular air filter, we recommend discussing air filter changes with your HVAC partner. In these cases, a licensed HVAC contractor is almost always required in order to remove the air filter safely and correctly. 

However, if you’re dealing with a more standard office or home air filter, then an air filter change is usually recommended every 2 to 3 months. 

In some cases, this timeframe could be extended to as much as 6 to 12 months, but this really depends on the inner workings of the office or home. Factors that can affect how often you change out your air filter can include:

  • The type of air filter you’re using
  • If there are pets indoors
    • What type and how many
    • Typically means every 1 to 3 months
  • How big the building is
    • The larger the building, the more air filter changes recommended
  • What the outdoor environment is like
    • Heavily polluted cities means more air filter changes
  • If the occupants suffer from allergies or breathing-related issues (like asthma)
    • Typically means every 1-2 months
  • How often the building is occupied and how many people occupy it
    • Is it a vacation property? (lowers the amount of changes in comparison to a permanent residence)
    • Is there only 1 person in the office at a time? (lowers the amount of changes in comparison to a busy office environment)

If you still don’t know when to change your air filter, here’s what we recommend.

If you’re still not sure how often to change your filter, then a good timeframe to live by is every 60-90 days. 

If you don’t have any pets and you live in a city with no heavy pollution, then you can stretch it to 90 days. If you do have pets, live in a heavily polluted city, or have occupants with allergies or breathing issues, then you should (at least) be replacing your filter at the 60-day mark.

If you’re in a work environment and you have employees or coworkers to worry about, then we suggest speaking with a commercial HVAC contractor. In traditional office environments, we would still recommend every 60-90 days, but this can change depending on your HVAC and your specific needs and habits.

Long story short: changing your air filter does make a difference. One simple task can help keep your HVAC unit working properly and your indoor air quality at a good level.
