The typical lifespan of an HVAC system is 12 to 15 years. However, with the right proactive maintenance and care, your HVAC system has the potential to live considerably longer and stronger if it receives sufficient care.


Filter – No matter your filter type, the fact is this: A regular changing of your filter is essential to effective HVAC performance. Think of the filter as the lungs of your system. Your system cannot breathe properly if your filters are clogged.

Indoor Blower – An indoor blower is what pushes air out of your system. It might sound like your system is on, and the motor might be running, but when your blower is clogged, it’s not moving the proper amount of air to efficiently heat or cool your home.


Noise – HVAC systems usually make the same humming, thumping, or buzzing noises. If your HVAC system is making an unusual sound, you might want to take a look inside. Odd noises usually have a repair issue linked to them, but there are times when a simple filter change solves the problem.

Cleanliness – Make sure you keep the outdoor unit clean of grass clipping, weeds, and vines so that it can breathe properly.


It is recommended you schedule professional HVAC maintenance at least twice a year. There are some homeowner-friendly tasks for maintaining your HVAC, but most tune-up tactics involve some pretty heavy lifting and should only be performed by a professional HVAC technician.

Here are a few maintenance responsibilities that you have full control over:

  • Wash outdoor coils – DO NOT use a high-pressure power-washer for this. A firm thumb grip on the hose tip is all you need.
  • Use programmable thermostats – Keep your system running only when it has to. Programmable thermostats are cost and energy efficient.

You want to keep your HVAC system functioning for as long as possible. Take a couple days each month to check up on it and perform some basic cleaning but know when it’s necessary to call in professional reinforcements. Follow this guide to a long system life and avoid a pile-up of problems that lead to costly repairs or replacement.
