The decision to replace or repair your furnace is based on a number of factors, including the age of the unit, safety concerns, cost of repair, how long you plan to live in the home, and whether your air conditioner needs to be replaced as well. If your existing unit is more than 13 years old and the repair is anticipated to cost at least $500, it is probably more cost effective to replace the unit. In addition to offering safer and more reliable heat, a new furnace will be more efficient, will lower your utility bills, and will come with a warranty to cover the cost of future repairs for a number of years.

If you plan to live in your home for the long term, it is better to proceed with the replacement sooner rather than later. Postponing getting a new system can result in more repairs, frequent outages, and replacing the unit at a higher cost at a more inconvenient time.

If you need to replace your air conditioner, installation issues may require you to replace your furnace as well. The coils in today’s high-efficiency air conditioners are taller than many older models and may not fit into the original furnace space. Newer furnace models are made to accommodate the larger air conditioner coils.
