How Long Will My HVAC System Last?

July 18, 2022 | Blog

Your HVAC system is essentially the heart of your household. It keeps your indoor air breathable and comfortable! A functioning air conditioner is essential, especially in the hot Louisiana summers.

But nothing lasts forever, unfortunately including your heating and cooling units. At Foulks Southern Air, we’re here to help you get the most from your system. Read ahead to learn more about your HVAC system, how long it should last you and what factors affect its lifespan!

Lifespans of HVAC Components

Your overall HVAC system should last around 15 to 20 years. However, it is made up of various pieces of machinery and other mechanical components! Each has its own service life and may need attention over time.

Air Conditioners

Air conditioning units last a lot longer with the help of professional AC maintenance. The average AC lifespan is about 12 to 17 years. You should schedule a seasonal tune-up every year, preferably during the Spring before it becomes too hot outside.


A furnace that undergoes proper maintenance will last anywhere from 15 to 20 years. Oil-fueled furnaces have the longest lifespan, while furnaces that are gas-fired have the shortest.

Regardless, regular inspections will help your system live a longer service life! You can schedule a furnace tune-up during the fall before it gets cold outside.

Ductless Mini-Split Units

Ductless, mini-split air conditioners usually last for 15 to 20 years. However, if these units are well-taken care of, they can last longer. Since mini-splits have more moving parts than a window AC, they require regular maintenance to run effectively.

Heat Pumps

Heat pumps have an average service life of 15 years. This timeframe may vary on how often it is used and if it is well-maintained. Heat pumps in coastal areas last less time, typically around 12 years.

When To Consider HVAC Replacement

AC replacements are unavoidable, even with regular maintenance. The lifespan of your heating and cooling unit depends on various factors. A few signs may signal the need for a household replacement.

You Have High Energy Bills

Energy bills will often rise during hotter or colder months. High energy costs are even expected with less energy-efficient systems. However, if your energy bill is high with no change in your unit’s routine, you may be in need of a replacement.

Your HVAC System is Old

Older HVAC models do not have the energy efficiency of newer models. Little energy efficiency can cause more wear and tear on your system. In other words, regular use wears down the system over time, causing it to run less effectively and increasing the need for a replacement.

Frequent Strange Noises

Most units operate with little noise. As time passes and parts grow older, you may notice strange sounds from your machinery. If you hear any squeaking or scraping sounds: you should call for professional maintenance.

A Constant Need for Repairs

An excessive need for repairs is not a good sign. Not only do repairs become expensive, but they may be a signal of a serious problem with your units. A replacement may be the more cost-efficient option if you are in need of consistent maintenance.

Professional & Very Courteous

The HVAC System stopped when my Generator quit. When restarting the generator, the AC did not restart. Manuel came out, checked the entire system & got it working in 20 minutes. He was brilliant, professional & very courteous. I’ve use this company for over 25 years & have always been completely satisfied with their service.
