Replacement Air Filters
Replacing your air filters on a regular basis is an extremely important part of maintaining a functional heating and air conditioning system. Air filters have two main functions. First, they pick up the particles in the air as they pass through the system thus, enhancing the air quality in the home. The other benefit is that filters protect your heating and air conditioning equipment from all the particles in the air. If you didn’t have a filter many of the particles will cling on to the coil and other parts of the system. Over time your system will become less efficient and cost more money to run because it is dirty.
Sometimes people forget to replace their filters in a timely manner and the filter gets so dirty that it is difficult for air to get through the dirty filter. During the summer a dirty filter can cause your air conditioning coil to freeze, during the winter your furnace can over heat from the lack of air circulation. In both cases, you become uncomfortable and it strains your system. As you can see from these examples, replacing filters is extremely important.
Gaithersburg Air Conditioning and Heating Services has a filter program that will fit your needs. Replacement air filters are available as single filters or by the case depending on the filter.
Basic Replacement Air Filters Information
Good replacement air filters have two main functions. They protect your equipment from the contaminants that are floating in the air and improve air quality. If the replacement filter didn’t catch the particles, the contaminants can get caught on the coil and other parts of your HVAC system. Over time, this will reduce your energy efficiency and your comfort.
Replacement air filters are typically measured in a MERV rating. MERV stands for Minimum Efficiency Reporting Value. The higher the MERV rating the more efficient the replacement air filter is in initially capturing particles. A good MERV rating for 1 inch thick air filters is between 8 and 11. Most of the replacement air filters that are purchased from us are a MERV 8 filter. These tend to last 4 to 8 weeks depending on the homes dynamics (system run time, number of people, pets etc).
- All 1 inch thick standard size MERV 8 replacement air filters can be delivered by the case (12 in a case) to your door for $99.
- All 1 inch thick standard size MERV 11 filters can be delivered by the case (12 in a case) to your door for $129.
