Your HVAC is one of those things that you hope you don’t have to worry about – ever. But the reality is that most units need to be replaced around every 15-20 years. In this post, we’ll explore just how long your HVAC unit should last, and some ways you can help yours last longer!


Not all HVAC units are created equal. You can typically expect furnaces to last about 15-20 years, and heat pumps around 16 years. Air conditioners can quit a little sooner – in about 10 to 15 years. Electric or gas heaters last about 10 years, and tankless water heaters about 20. Thermostats can last up to 35 years.

Here are a few of the factors that impact how long the components of your HVAC will last:

  • Maintenance: HVAC units require regular maintenance. Only getting service when something goes wrong will reduce the life of your unit. Licensed professionals, like the ones at City Plumbing Heating and Air Conditioning, can identify problems and prevent them from getting worse. Regular maintenance will also increase your unit’s efficiency, keeping your energy costs low.
  • Air filters: If we’ve said it once, we’ve said it a thousand times. Regularly changing your air filters will do wonders for your HVAC system. Once every month is a good rule to follow, but once every three months is pretty much mandatory. If you don’t clean out your filters, this causes air to be restricted as it flows through your system, making it work harder, and costing you money!
  • Climate: Here in West Texas, we’re lucky. Our summers aren’t too humid, our winters are relatively mild, and we usually have a temperate spring and fall. That means the total time we spend running either heat or cold is less than, say, a midwest city with extreme heat in the summer and extreme cold in the winter. Of course, your A/C probably saw a lot of wear and tear this summer, with temps in the 90s or hotter for what seemed like 8 months straight. You want to stay comfortable, but programming your thermostat to fit your climate will help you get the most out of your HVAC!
  • Technology: Advances in technology are so frequent these days that you may choose to get an upgrade to your HVAC even while your current system is still running great. For example, programmable thermostats that work with your cell phone are just one advancement that is an option for homeowners looking to maximize value and efficiency.
