How long does a Heating and Air system last? | When should you replace it?

March 12, 2020

One of the top 10 most expensive repairs to a home is the heating, ventilation, and air conditioning (HVAC) system, though it isn’t the priciest item on the list (looking at you, Foundation Repairs). So it’s no surprise that two of the main questions homebuyers ask are “How old is the system?” and “How long will it last?”

The average answer to how long typical heating and air systems last is 10 to 25 years. That’s a long-ranging answer because of the factors and many parts involved. How long a system will last depends on use, how well your system is manufactured, and how well the system is maintained. The average lifespan of individual components of a system looks like this:

  • Furnaces: 15 to 20 years
  • Heat Pumps: 16 years
  • Air Conditioning Units: 10 to 15 years
  • Tankless Water Heaters: more than 20 years
  • Electric or Gas Water Heaters: 10 years
  • Thermostats: 35 years


Maintaining Your Heating and Air System

As with most other components of your home, proper and regular service and repair maintenance are key to longevity. To get the most out of your heating and air, be sure to:

  • Remove debris from the outside unit.
  • Change your air filter every three months. If you have pets or allergies, change it once a month. 
  • Have repairs done as soon as you notice a problem.
  • Schedule regular maintenance with a McElroy’s technician at least twice a year – once before summer and once before winter.

Replacing Your HVAC System

Proper maintenance will get you longer use out of your heating and air, but at some point it will need to be replaced. Here are signs it may be time to consider investing in a new system:

  • High Energy Bills

The Kansas weather may be unpredictable, but on average, your monthly energy bill should be similar to the same month in previous years. If you notice more energy usage, it may be a sign your system is operating with less efficiency.

  • Inconsistent Indoor Temperature

An aging system may struggle to keep your home at a consistent temperature. You may also notice an increase in the amount of time it spends running.

  • Increased Dust

This could be a sign that your air conditioning system is losing efficiency and not able to remove the dust.

  • Unusual Sounds from the system

As the system ages, it may make odd noises, such as grinding and squealing. If this happens, have the system inspected as soon as possible. McElroy’s offers 24-hour emergency service by calling 1(877)-McElroy.

  • Pricey Repairs Needed

If your system is more than 10 years old and in need of a repair that would cost more than half the price of a new AC, it may be a better investment to upgrade to a new system.
