Why You Need to Change Your Air Filters Regularly - Parker & Sons

Your heating and cooling system works hard every day to keep you feeling comfortable in your home. But, the air filter works just as hard.  The air filter may not seem like a very important component, but it actually contributes to the air quality in your home, the energy efficiency of your system, and the lifespan of your system.

Why Should I Change My Filters? 

Air Quality. Air filters do exactly what you would expect them to do – they filter the air. The air filter removes dust, pollen and other particles from the air that would otherwise enter your home. If it’s clogged, unfiltered air can bypass your filter and circulate into your home.


Efficiency. A clogged filter creates difficulties for the air handler, forcing it to work harder to push air through.  This causes your HVAC system to use more energy, leading to higher energy bills.


Longevity.  Neglecting to change your air filter regularly leads to a clogged air filter – the #1 cause of HVAC system failure.  Clogged air filters that force your air handler to work harder can cause your blower motor to overheat, leading to premature system failure.


According to ENERGY STAR:

“A dirty filter will slow down air flow and make the system work harder to keep you warm or cool—wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.”



Always check the manufacturer’s recommended filter change schedule and type of filter when choosing the right filter for your unit. You can always check with your HVAC technician to guide you to the correct air filter for your system.  At Parker & Sons, as part of a system tune-up we’ll check your air filter and help with any recommendations.
