Heating, Ventilation, and Air Conditioning systems are one of the biggest investments you make for your home. Most HVAC systems will last approximtely 15-25 years depending on the type of system and other contributing factors.  Unfortunately, you will have to replace the system at some point, no matter how well-maintained it is.

Here are 5 ways to know if it's time to start thinking about replacing your system:

Increase on Energy Bills

One of the first signs of HVAC trouble many homeowners notice is rising energy bills. If your daily routine is staying the same but the costs aren't, it's a good indication that your HVAC system is not as efficient as it once was. Older HVAC systems use more energy to created conditioned air, even if they’ve been maintained well.

Constant Repairs

In the long run, spending money consistently to keep your unit running for the next few years isn’t cost effective. Instead, you should use that money to invest in a new system. Get routine maintenance on that system to extend its life and lessen the severity of any future repairs.



Most HVAC systems will last approximtely 15-25 years. After that, it's time to invest in a much more energy-efficient unit that has earned the ENERGY STAR label. 


Are you starting to notice new noises, or louder ones, coming from your system? It's natural for your system to make some noises as it ages, but an increase in odd sounds means your HVAC will require more maintenance moving forward. Some parts can be replaced inside the unit, but eventually the system will wear out altogether. 

Running Duration

When your AC or furnace runs for a long time, it indicates it’s having trouble producing and circulating enough air around your house to maintain the correct temperature. A new system will be able to maintain the temperature in your home efficiently.
