5 Signs It’s Time to Replace Your Heating System

It’s important to know when it’s time to replace your heating equipment to prevent a total system shutdown on the coldest days of the year. These are just some of the biggest signs that you need a new heater:

  1. System age: Heating systems last an average of 15–20 years. If your unit is approaching this time frame, it could be time for replacement.
  2. Repair frequency: If you’re scheduling heating repairs more often, your system could be on its last legs.
  3. Reduced efficiency: Sudden spikes in your heating bills can point to failing system components that require replacement.
  4. Repair cost: If the cost of heating repair is 50% or greater than the price to replace your system, an upgrade may be more cost-effective.
  5. Total shutdown: A complete system shutdown is one of the strongest signs that your unit needs to be replaced.
