Issues Caused By Dirty HVAC Filter

Your HVAC unit is a modern marvel of efficiency, performance, and reliability. With routine care and maintenance, a heating and air-conditioning system can operate well in excess of a decade while providing comfortable conditions in your home. However, one of the easiest, least costly HVAC maintenance measures can lead to considerable problems if ignored, damaging your system and costing you potentially thousands in HVAC repair bills and replacement costs. When you fail to change your HVAC air filter regularly, you risk damaging your system or at least reducing its efficiency and quality of performance.

Keep reading to learn more about the issues that are caused when you run your HVAC system with a dirty filter.

Lower Energy Efficiency

When you run your system with a clogged filter, your unit must work harder to pull air into your system. Imagine breathing with a pillow over your nose and mouth, and you’ll understand the strain that a clogged filter places on your system’s ability to draw in air. The component that’s responsible for drawing in air, the blower, must work overtime when your filter is clogged, which means it uses more energy. That hurts energy efficiency, since the blower must use more energy to move the same amount of air. Also, because system performance is impacted by a clogged filter, more energy will be used to maintain the desired temperature. Both of those factors influence energy efficiency, which will cost you more money on utility bills.

Poor Performance

Clogged air filters cause reduced airflow through the HVAC system because the blower simply strains to move air into the system and throughout the house. The reduced velocity of air moving through the system can cause pockets of air to remain unconditioned, which leads to temperature variances between rooms within the house. That can prevent stabilization of your indoor temperature and cause your HVAC system to run longer than necessary as it tries to balance the temperatures with the desired thermostat setting.

Change air filter Frozen Coils

When your air conditioner system runs with a clogged air filter, it can cause the coil in your system to freeze. The coil is an important part of the cooling and drying process, as the coil represents an area for interchange of temperature between outside air and the conditioned air. When there isn’t adequate air flow to allow condensation on the coil to evaporate quickly, it can freeze, which will further depress the efficiency and performance of your HVAC system. Not only do frozen coils hamper high performance, but they can also lead to costly repairs and system breakdowns.

Dirty Air

The HVAC air filter is in place with one purpose in mind, and that’s to filter out particulate matter that can settle in your ducts or move throughout your house and lower indoor air quality. However, because the filter catches those contaminating elements, when it becomes overly clogged that can lead those elements to be released back into the system where they can foul the ducts and create health problems for anyone in the home. The best way to keep the air in your home clean and free of dust is through regular changing of the air filter.

Changing the air filter in your HVAC system may be a simple task that every homeowner can accomplish, but it’s also one of the most critical maintenance measures that must be undertaken. Failure to tend to your filter can cause poor air quality while damaging your HVAC system permanently and elevating your energy bills needlessly.
