change your air filter regularly palm beach county floridaIf you haven’t changed your filter for your HVAC (heating, ventilation and air conditioning) equipment this month, it’s a good idea to check it, and then clean it or replace it if it’s showing an accumulation of dirt and grime. Your air filter is a critical component of your HVAC system because it keeps your system clean and running optimally. That’s why it’s important to check, and potentially change, your filter every month or two.

When the dust builds on your filter, the airflow slows through the air handler, which makes your HVAC system run longer to reach your desired temperature. This increases your energy bills, and causes wear and tear to your system’s components. If enough dust builds over the evaporator coil, the coil can freeze over in the summer, which can cause flooding indoors when the frost melts.

If you haven’t changed your filter lately, you can stave off these issues by changing them now. The type of filter that you use makes a difference. Filters have efficiency ratings called MERV (minimum efficiency reporting value), which indicate their effectiveness at trapping particles based on size. The scale runs from 1 to 16 for residential purposes, and a higher MERV-rated filter traps more and smaller particles.

However, filters with higher MERV ratings may need to be changed more frequently, but their benefits outweigh the additional effort. Denser filters trap smaller particles, including pollen and possibly mold spores. Besides keeping your air handler cleaner, your indoor air quality will improve, as well.

If you want to use a denser filter, it’s a good idea to find out the maximum MERV rating your system can use. The air handler relies on a precise amount of air flowing through it. If you haven’t changed your filter, but are planning to, consult your HVAC system’s owners manual. If it doesn’t state the maximum MERV value, contact Robert R. McGill Air Conditioning.
