Furnace Repair in Chattanooga

Furnace replacement in Chattanooga comes up less frequently than AC replacement, and when it does it's almost always driven by age and accumulated repair history rather than a single dramatic failure. A gas furnace in Chattanooga that's been well maintained and used through a relatively short heating season can last fifteen to twenty years. The systems we're replacing most often are ones that are well past that range and have developed problems that repair can't cost-justify.

The efficiency argument for furnace replacement is real but somewhat less compelling in Chattanooga than it is in markets with longer heating seasons. A high-efficiency furnace operating at 96 percent AFUE versus an older unit at 78 percent saves meaningful money in a climate where the furnace runs for five or six months. In Chattanooga, where the heating season is four months in most years, the annual savings are present but the payback period is longer than it would be in Cleveland or Minneapolis. We'll give you the actual numbers for your situation rather than a generic efficiency pitch.

What does make the replacement conversation more straightforward in Chattanooga is when a heat pump is the alternative being considered. For a home that's replacing both a furnace and an aging AC system at the same time, a heat pump system handles both heating and cooling with a single equipment investment and operates efficiently in Chattanooga's climate for most of the heating season. We cover that option in detail on the heat pump page and it's worth looking at before committing to a like-for-like gas furnace replacement.

Furnace installation in a Chattanooga home involves equipment removal, venting and flue assessment and modification as needed, proper sizing for the home, and commissioning. We don't assume the previous system was correctly sized. An oversized furnace short-cycles and an undersized one runs continuously on the coldest nights, and either condition affects both comfort and equipment longevity.
