FURNACE AIR FILTERS TIP, The Key To A Healthy HVAC System... When we work in a dirty environment, we usually wear a mask to protect our lungs. The filters in your hvac system have the same function. The filter in your hvac system has two main functions. First it helps to improve your homes indoor air quality. This can improve the health of your family. According to the U.S. EPA, the air inside your home can be 2 to 5 times worse than the air outside. The second thing they do is to keep your hvac system clean. If the dirt gets through the filter it can clog your furnaces secondary heat exchanger. This can happen if you have a condensing type furnace. If you dont have a condensing type furnace, the dirt will collect on your ac units evaporator coil. Either way, this restricts air flow. This in turn can cause higher temperatures during heating system operation and premature failure of parts. During cooling operation, the operating efficiency will be reduced, your electric bills will go up, and it will cause more wear and tear on system parts. Locating your filter... The filter is usually located in one of the following places: 1. In a grille in your wall or ceiling. These are commonly called return air filter grilles. 2. In a slot on the side, bottom or top of your furnace. It depends on the style of furnace you have. 3. Inside the blower compartment of the furnace. This is common on older furnaces. Most manufacturers do not recommend this on new furnaces. Filter efficiencies... Air filters have a standard rating. This rating, minimum efficiency reporting value (MERV), is a number from 1-16. You dont have to know all the technical jargon. Simply put, as the number goes up the unit will stop more and smaller particles. GIVE US A CALL TODAY! 403•894•4989
