HVAC systems, like cars, will run better and last longer with proper care and maintenance. But not many of us really know what to do to maintain them. Most of us have lots of questions, like: "How often should I change my filters?" and "If I use a media filter -- the special, big, expensive, 4-inch thick ones -- should I also use the disposable ones in return air chases?" etc., etc. The HVAC Talk Forum is a really good place to go for information and to get free information, advice and suggestions from HVAC pros.
