A combination of insulation improvements, air sealing, and winterization projects will help ensure your heating system is efficient and long-lasting. The worse your home's insulation, the harder your heating and cooling system will have to work.
The flames from the burner component heat a metal heat exchanger. The heat circulates through the looped tubes of the heat exchanger, transferring the heat to air.
An efficient and well-maintained heat exchanger is essential for a working furnace. During the process of heating the heat exchanger, combustion gases should be venting safely out of the house.
In order to maintain an efficient furnace, annual professional maintenance is not a suggestion—it's a requirement. AFUE will decline over the years due to ductwork leaks and inefficiencies, dirty furnace components, loose and damaged parts, and clogged air filters.
