5 Signs to Replace Your Heating System

Old or broken furnaces cost you time, money, and headaches. Here are some signs that your heating system may be ready for a replacement:

  • Expensive repairs: Cracked heat exchangers, faulty ignitions, broken blower motors, and bad thermostats can all drain your wallet. If your heater is breaking down repeatedly, the price of repairs can cost more than a new system quicker than you realize.
  • Age: Even a well-maintained system deteriorates over time. If yours is 15 years or older, it’s a good time to invest in a replacement.
  • High energy bills: Your rising energy costs may be a sign that your furnace is using extra energy to heat your home.
  • Weird noises: Structural problems with your heating system, like leaks and cracks, can cause your unit to bang, rattle, or hum.
  • Inconsistent heating: If some rooms in your home are staying warm easier than others, it can be a sign that your system needs to be replaced.

Ideally, you should replace your system in the early fall. But the best time to replace your furnace is any time besides the winter. You don’t want to risk any complications and spend unnecessary time in the cold without a working heater. This is especially important in New York.
