Knowing When to Replace Your Heating or Cooling System

Upgrading your heating or cooling system is a significant investment, and understandably, it's one that you want to make sure is necessary. You wouldn't want to replace your system prematurely, wasting valuable resources. But equally, you don't want to wait too long, ending up spending time and money on repairs that merely put a band-aid on an issue that requires a more comprehensive resolution. Recognizing the signs that you may need to replace your system can help you make an informed decision on the right time for an upgrade.

Here are a few signs that it may be time to replace your heating or cooling system:

  • Your system is 10-15 years old or more
  • You are constantly calling for repair work
  • Your energy bills are increasing
  • You are experiencing inconsistent heating and/or cooling
  • Your system is short-cycling
  • You hear unusual noises while the system is running

Are you facing one or more of these signs? Reach out to Bergeron Mechanical Systems for professional advice on whether it's time for an upgrade. We're committed to helping you make the best decision for you. At Bergeron Mechanical Systems, we always try to find a viable repair solution before recommending replacement.
