While October temperatures in Chattanooga are pleasant, it won’t be long until it drops into the low 40s at night. If you’ve been struggling to keep your home comfortably cool all summer, it may become just as difficult to keep it warm in the winter. You may be wondering if it’s time for a new HVAC system.

How Long Should My HVAC System Last?

When it comes to your system’s efficiency, the ENERGYSTAR website makes some well-considered recommendations for when you should get a new HVAC system:

  • Heat Pump: 10 years

  • Air Conditioner: 10 years

  • Furnace: 15 years

  • Boiler: 15 years

Signs of Imminent Failure

The lifespan of your HVAC is important, but more practically, it’s the system’s performance that really matters. After all, not everyone can afford to replace such expensive equipment that often.

However, there are a few signs and symptoms you can check to help you decide whether it’s more cost-effective to get a new HVAC system.

1. Your utility bills skyrocket

While changes in the season can mean a change in your average bill, if your cost for electricity rises rapidly and steadily, it may be time for a new system.

Your HVAC system’s efficiency will drop off as it gets older, meaning your cost to run it will go up. If this is the case, consider getting an estimate.

2. Temperature settings aren’t maintained

Another sign that your system may be beyond its useful life is if it cannot maintain the set temperature. When you’re paying more and getting less, it’s time to consider that you need a new system.

3. Uneven temperatures throughout your home

Too cold or too hot is bad, but so are uneven temperatures throughout the house. Your HVAC system should be able to provide even temperatures and humidity levels, and if can no longer perform, it may have outlived its useful lifespan.

4. Constant running

If it seems that your system is always running just to keep up with the thermostat, it’s overworking and adding to the problem.

5. Frequent repairs

Regular calls to your local repair technician may mean that it’s simply time to retire your old HVAC system. Blown capacitors and leaky coils are a warning sign of impending death. Consider the cost savings of a new, more energy-efficient model over the elevated electric bills and repair costs.

Before Buying a New HVAC System

While a new HVAC system will prove more efficient and effective over time, make sure you’re not spending your money needlessly.

Perform an energy audit of your home to ensure it’s properly insulated. Poor performance from your system may be caused by dirty or damaged ductwork or an imbalance in your system.
