Coleman is here to help!  We are dedicated to our customers, providing Knoxville, TN the best heating repair service in the area.   Repairing your furnace or heat pump is definitely something that needs to be handled by the professionals.  While Google is extremely helpful, it is difficult to know exactly what’s wrong with your heating unit.  The DIY’er can’t know precisely what matter is at hand, which means you could be trying to solve the wrong issue or trying to solve the issue by taking an incorrect approach.

Preventive maintenance is something that is often overlooked, however the benefits are quite significant. Since heating your home is a substantial factor in your energy bill, many customers have reported notable savings.  According to the Department of Energy, heating your home uses more energy and costs more money than any other system in your home — typically making up about 42% of your utility bill!  

Preventative maintenance not only results in cost savings, but it also allows your heating unit to perform efficiently — resulting in fewer breakdowns, maximizing the lifespan of your unit, and providing cleaner air in your home.
