Furnace Repair San Jose, CA
There are many various types of furnaces available on the market today. For both residential and commercial, the two most common are gas furnaces and electric furnaces. The basic way that a furnace operates is by having a heating element or heat exchanger that blows air over and goes through your duct work, heating your home.
Gas furnaces and propane furnaces work by burning fuel. However, not all models are able to utilize the energy produced from the flame in the same ways. A basic furnace these days is 80% efficient. Today, higher efficiency furnaces are available and have become increasingly popular for homeowners due to the decrease in their utility bills and a green outlook toward preserving the environment.
