How Long Will My New HVAC System Last?

New HVAC System

Whether you own or rent your home, your heating and air conditioning unit must be maintained. With proper maintenance, most HVAC units can last anywhere between 15 and 25 years. However, the longevity of your system does depend on the quality of install, type of system and even where you reside.

Conditions That Affect Lifespan

The lifespan of your unit not only depends on the type but also on how it's maintained. Both improper installation and maintenance can dramatically shorten its lifespan. Improper usage, which can include setting the temperature too high or too low, can also negatively affect your system's longevity.

Furnace

Most gas furnaces last around 15 years, though with proper maintenance, some models can last as long as 30 years. Furnace lifespans are influenced by installation efficiency, ventilation and the quality of routine maintenance. Only repairing a furnace when it's stopped working will shorten its lifespan, which is why having an HVAC professional check yours at least once a year is important.

Air-Conditioning Units

There are several common types of air conditioning units, and each one has its own average lifespan. Central AC and ductless mini-splits last between 15 to 20 years. The size of the unit will largely impact how long it works; central air conditioners that are too large for the house they're connected to wear out faster due to the strain placed on the compressor.
 
Compressors are expensive to replace, and if your unit is already too big for your home, it's best to upgrade to a newer model. Usage plays another key factor in an air conditioner's lifespan, particularly how it's regulated and maintained. Failure to clean ducts, replace air filters or get necessary repairs will naturally lead to early failure.

Heat Pump

Heat pumps last around 10 to 15 years, though newer models can last longer than average. An air-source heat pump might last longer than a water-source heat pump, but a dual-source heat pump tends to last the longest out of all three models. Although they can perform the job of a central heating and cooling system for less energy, heat pumps tend to wear out faster in cold climates. Extremely harsh winters could result in the need for a secondary heat source.

Boilers

Boilers last approximately 15 years, and they can be a cost-efficient heating solution for many households. However, because they are connected to a home's plumbing system, they do run a risk of experiencing breakdowns caused by frozen or burst pipes. For this reason, we advise consulting with an HVAC professional about proper boiler insulation.
