Clogged Air Filters

Air filters are used to keep the air in your home or office clean and to keep your furnace or air conditioner clean. Dirt from the air can clog your air filter and cause your appliances to work double time to get air through your home. This extra effort can cause some serious problems up to and including your HVAC system shutting down all together.

As a filter gets clogged up with dust and debris it gets harder and harder for air to move through. This means your air conditioner has to work twice as hard to compensate for the reduction in air flow. This leads to subpar cooling and the temperature in your home can become inconsistent and inadequate. This also leads to unhealthy air. If your air filter is too full of the dust and debris that it usually filters out, the particles then recirculate back into your home.

The most serious consequence for not keeping a consistent maintenance routine and changing your air filters is a costly repair when your HVAC system fails. A dirty air filter can eventually cause costly internal damage.

Please remember to change your air filters every 3-6 months or according to your manufacturers recommendations. Call us at 877-7-CHAVES if you have any questions about the quality of your air or the cleanliness of your air filters.
