“Airflow is the key to your entire HVAC system.” This seemingly obvious statement from Corey Richmond, one of our talented technicians, hit me like a lightning strike. He went on to explain how those little one-inch thick filters which cost less than $20, in most cases, are the key component to an efficiently operating air conditioner and/or furnace. It was a great reminder, and something that might just save you a lot of money and help you avoid sitting in a steamy house waiting to have your air conditioning repaired.
If you don’t change out your filter, it will get clogged with dirt, dust, hair and other debris. Air cannot flow into your AC unit and around the evaporator coils where heat and moisture are removed. This will result in the coils of your AC unit “freezing up” and your system will stop functioning as designed, causing the temperature in your house to rise. A hot, humid house is not ideal, but that may be just a symptom of a more serious problem.
Once you replace the filter on a frozen-up system, it can lead to other issues. As the system thaws, it may fill up your drain pan too quickly which can cause it to overflow. This pan is often located above your furnace and control board. If the control board gets wet, it can lead to a malfunctioning HVAC system or cause it to stop working all together. Depending on the age and efficiency level of your system, an HVAC repair may be so expensive that a brand-new high efficiency system might be a better choice in the long run.
