When cold temperatures are constant, you rely on your furnace to stay warm and comfortable. To stay out of the cold all season, it pays to learn the signs you need a new furnace installation. As Columbia Falls, MT’s go-to HVAC contractor, Denning Sheet Metal is prepared to handle your heating and cooling needs year-round—from air conditioner installation to geothermal heating solutions. Here, their team shares three signs you’re ready for a furnace replacement.

When to Replace a Furnace, According to an HVAC Contractor

Age

The average furnace lasts 20 to 30 years. Once yours creeps up on the 20-year mark, start investigating replacement options. You can determine your unit’s age by reviewing the owner’s manual, calling the manufacturer with the model number, and looking for visible signs of wear and tear. If you notice rust or cracks, call your HVAC contractor for further investigation. Age-related issues usually can’t be resolved, so if you don’t want your unit to break down in the middle of winter, make replacement a priority.

Frequent Furnace Repair

While the occasional furnace repair is normal, if you’re calling your contractor every week, a replacement will save you money in the long run. Frequent reasons for repair include uneven temperatures throughout your residence, frequent cycling on and off, odd noises, and the emission of contaminants that weaken indoor air quality. If any of these signs arise regularly, your unit’s on its last legs. 

A Low AFUE Rating

If you think a furnace replacement is necessary, call your HVAC contractor. They will use an annual fuel utilization efficiency rating (AFUE) to assess your unit’s efficiency. According to experts, the rating shouldn’t drop lower than 80%. If it does, your unit isn’t operating at maximum efficiency. Essentially, you’re throwing money to the wind, and a new furnace installation would instantly lower the unit’s energy needs. New models can reach up to 97% efficiency, guaranteeing warmth at an affordable rate.
