Replacing Your Home Air Filter and Why It’s Important.

Replacing Your Home Air Filter and Why It’s Important.

According to the numerous HVAC professionals we speak to on a daily basis, there is no “set in stone” cycle for replacing your home air filter. The replacement cycle can depend on the quality of the filter, the quality of the air in your area, and even the average temperature in your area. That being said, many of us here at Prosaver replace our home air filters every 3 months, and here’s why…



The majority of our employees and customers have at least one household pet, but did you know that an old air filter can spell disaster for your air quality if you have furry friends at home? The allergens released, and the fur typically shed, will find it’s way through your HVAC system and into the filter. Over time these contaminants build up and eventually clog your air filter entirely, which can result in poor air quality and reduce the life of your heating and cooling systems. Whether you have a dog or cat, be especially vigilant about changing that filter, as it will become dirty twice as fast as a household without animals.



One of the most costly mistakes anyone can make is to void a warranty on an expensive home appliance. If you neglect to change your air filter, you may be doing exactly that. If your air conditioning system breaks down while under warranty, whether that warranty is from the manufacturer or a supplemental provider, your claim can be denied if the service technician finds your air filter clogged.



When your household has a dirty air filter, your air conditioning system has to work harder to push the cold or hot air through the filter. This extra workload can result in a 5 to 15 percent increase in energy consumption by your air conditioning system. According to the U.S. Department of Energy, changing the filter regularly keeps your energy costs down up to 15% on that HVAC system, and who doesn’t need a little extra cash in their pocket at the end of the month? Also, changing the filter every three months can increase the lifespan of your system over one that has it’s filter replaced less frequently, which saves money by helping you get the maximum lifespan out of your system before it’s time to replace it.


HVAC systems are costly and crucial to our home comfort. By simply changing your air filter every three months, you can give yourself added peace of mind that when temperatures go south of freezing in the coming winter months, you have done what’s necessary to keep you and your family warm.
