Is it worth fixing an old HVAC unit?
If your HVAC unit is 15+ years old, you may be wondering if it’s worth putting more money into repairs or if it’s time to start thinking about replacement.
Most residential AC systems have a typical lifespan of around 10-12 years. As a system gets older, major repairs can become harder to justify, especially when you’re dealing with an expensive component failure, declining efficiency, or an older refrigerant system.
Spending several hundred dollars on a repair might get you through another season, but if your system is already nearing the end of its expected lifespan, that money may be better put toward a newer, more efficient system with a manufacturer’s warranty.
How Long Should a New AC Last?
A properly installed and maintained air conditioner can often last 15 to 20 years. Regular maintenance is one of the best ways to help your system reach the higher end of that range.
A few simple things can make a big difference:
• Schedule annual AC maintenance
• Change your air filter every 1 to 3 months
• Keep the outdoor unit clear of grass, leaves and debris
• Address small problems before they turn into expensive repairs
And when the time comes to replace your system, choosing the right equipment and having it professionally installed can make a big difference in how long it lasts.
