When calculating the costs of air filters, it’s important to consider how often each type needs to be replaced. While high-efficiency filters may have a higher initial cost, their longer lifespan can make them more economical in the long run. For instance, if a HEPA filter lasts three times longer than a standard filter, it could ultimately save you money over time.
Neglecting to change your air filter regularly can lead to several problems that impact both indoor air quality and the performance of your HVAC system.
A clogged filter forces your HVAC system to work harder to pull air through, which can cause unnecessary strain. Over time, this extra load can lead to system malfunctions and costly repairs or replacements. Replacing filters on time helps extend the lifespan of your HVAC system and its components.
Furthermore, when your system struggles to draw air through a dirty filter, it runs for longer periods, consuming more energy. This higher energy usage results in increased utility bills and a larger carbon footprint. Regular filter changes can help mitigate these issues and improve overall system efficiency.
If your air conditioning system is not cooling your home or business, it is most likely a due to low refrigerant, the capacitor, compressor, blower or an electrical issue.
If your air conditioning fan is not spinning at your home or business, it could be attributed to the capacitor, motor failure, contact issues, burned out fan motor, debris obstruction or a tripped breaker.
If your air conditioning system is leaking water, it is most likely due to a obstruction in the drain line that is causing the drain pan to fill and leak. It could also be the drain pan itself has damaged or rusted, improperly installed or not properly leveled.
Manufacturers suggest that you change your air conditioning filters every quarter (3 mo.); however, the homeowner should consider variables such as allergies, respiratory issues, pets, home traffic and frequency of exposure to outside elements (windows and doors open).

The 20 degree rule refers to a guideline that the temperature difference between the supply side air and the return air, often expressed in a 20 degree difference across the evaporator coil.
A system typically will cycle off and not restart no earlier than 3 minutes after shutoff to allow for equalization of the system.
* The aforementioned times are estimates based on the equation below and can be effected by many variables.
Variables:
Equation: Q = m×C×ΔT and m = V×ρ
