Recognizing It Is Time for Heater Replacement

A reliable heater or furnace will last for well over a decade, but there are some telltale signs that it is time for a heater replacement. You never want to be vulnerable to a freezing cold home in the middle of January, so make sure your system is in proper working order before it is too late. We can help you recognize when it is time to replace your unit. Call First Class HVAC in Delaware if you notice any of the following:

  • Noise – Grinding, banging, and squealing noises are symptoms that something is wrong with your unit. It may be repairable, but we will need to take a look.
  • High energy costs – If your utility bills are on the rise despite no changes to your routine, your heater may be showing signs of its age. Investing in a new model is sure to improve energy efficiency and lower your bills.
  • High repair costs – You should replace your heater if it requires multiple repairs in the same year or if its repair costs exceed half the price of a new unit.

Our team is committed to serving you, so we will not suggest heater replacement unless you need it. When possible, we will provide our heating services to keep your system running like new.
