Your home air filter does more than impact the air quality in your home. Air filters play an essential role in the performance of heating and cooling units, impacting energy efficiency and system lifespan. This small, inexpensive component of your system impacts so much, it’s essential to clean or change it regularly to avoid system repair headaches. What can happen if you neglect air filter maintenance?
A clean filter facilitates the free flow of air through your system. When clogged with dust and debris, airflow is restricted, causing the system’s internal temperature to drop, eventually causing the coils to ice. When we get calls from our customers to fix AC unit because their AC is blowing warm air, this scenario is a prime suspect.
If your system is struggling, but your coils are not quite at the point of freezing, you may notice uneven temperatures throughout your home.
Before you call for HVAC repair services because your system is short cycling – constantly turning off and on – check to see if your air filter is dirty. Letting this problem continue unaddressed could leave you with a pretty hefty energy bill.
Dust, pollen, mold, dander, germs, and debris that a clogged air filter can no longer filter out will be recirculated back into your home. This is especially dangerous for people with allergies and respiratory conditions.
Allergens from a dirty air filter can buildup, potentially leading to mold growth in your ductwork over time.
Dust and dirt can also get into internal system components, causing wear and tear, resulting in the need for costly emergency ac repair down the road. In fact, a dirty air filter is the most common culprit found by technicians attending repair calls.
The added wear and tear from dirty filters will shorten your system lifespan, leading to the need for early replacement. The nominal cost and inconvenience of replacing an AC filter pales in comparison to the thousands it will cost for a new system.
Ignoring the need to change your air filter due to the cost will cost you more in the long run. A dirty filter forces your system to run longer and work harder to cool your home, inflating your energy bill.
Checking your filter just once a month and replacing it if it’s dirty can save you some serious repair issues. Make it part of your HVAC regular maintenance.
