How Long Can Your HVAC Unit Go Without Maintenance?

HVAC maintenanceIf you keep putting off HVAC maintenance, how long will it be before a furnace or air conditioner fails? It’s hard to predict the exact time frame, but you can probably count on one thing: It will happen at the most inconvenient and uncomfortable time; probably during a frigid cold snap or a sweltering heat wave, when the system’s under maximum stress.

Proper HVAC maintenance not only supports reliability, it also impacts energy efficiency, which in turn is directly related to lower monthly operating costs. Another factor is the warranty. The terms of most HVAC warranties specifically require a record of annual professional HVAC maintenance in order to keep the warranty in force.

Furnace Life Expectancy

Assuming proper annual preventative maintenance, a gas-fired central furnace can be expected to last between 15 and 30 years. To reach that life span, any needed repairs along the way should be handled only by certified HVAC technicians. Many experts point out that while a 30-year-old furnace may be still functional, technology in the unit has likely been surpassed by newer models that provide improved energy efficiency, lower operating costs, and more options. Therefore, replacing the furnace earlier in its life span may be a better choice.

AC Life Expectancy

Central air conditioners can generally be expected to provide dependable cooling for anywhere between 12 and 17 years, depending on the specific brand. Factors that impact this estimate include manufacturer-recommended annual maintenance, as well as variables like local climate and daily hours of operation. Studies show that without professional maintenance, an air conditioner may fail in as little as five years, requiring expensive repair or replacement of costly system components. In the event proper annual maintenance has been neglected, the warranty is void and all costs shift to the owner.
