5 Signs You Need to Replace Your Furnace

An aging or faulty unit will often show signs that it needs replacing. However, these systems tend to lose their efficiency as they age.

Signs you need a new furnace include:

  • Age: Check the serial number or manual for the age and talk to a technician about a plan to replace it if it’s already over 15 to 20 years old.
  • Uneven heating: If some rooms are cold while others are warm, the cause might be a malfunctioning thermostat, air leak, or the single-speed blower is heating unevenly from antiquated technology.
  • Higher energy costs: It could be a ductwork leak or a clogged air filter raising your utility bill. Compare your bill to last year’s and if the rate has not increased, the furnace likely needs work.
  • Frequent malfunctions or breakdowns: A furnace near the end of its lifespan will often need more repairs. Don’t sink more money into an old system when replacing it could help you save in the long run.
  • Weird odors: A chemical or metallic smell might be an electrical problem or malfunctioning component. Musty odors might be mildew or mold. If the heat exchanger cracks, it can leak dangerous carbon monoxide.

FAQs

Typically, installation takes about four to eight hours but can vary depending on the complexity of the installation.

Unless you have extensive HVAC experience, it’s not recommended. An installation mistake can present a safety hazard, breach your warranty, and increase insurance premiums. DIY work without a license is also not code-compliant.
