How To Change Your Furnace Filter Or Air Conditioning Filter By Bill Whitworth

Tracking down space heaters that are energy efficient isn't always simple. Furnace filter should be changed every month or two during heating season, and the circulating fan oiled once a year. When hunting for a company to maintain your system, look for one that designs, installs, and services the type of system you have. If your system is older than this, you might want to have its condition assessed. Start your search by asking neighbors, friends and family what companies they hired to replace a furnace or air-conditioning system. If they were happy with the installation, ask their contractor to come over and talk to you about heating or cooling your house. Of Energy and Consumer Reports
