Frequently Asked Questions about Furnace Repair

Is your furnace acting up? Get answers to common questions about furnace repair and find trusted local technicians.

What are the signs that my furnace needs to be replaced?

If your furnace is exhibiting any of the following signs, it may be time for a replacement:
  • Age: If your furnace is 15-20 years or older, it is likely less efficient and more prone to breakdowns.
  • Frequent Repairs: If your furnace requires frequent and costly repairs, it may be a better financial decision to replace it than to continue fixing it.
  • Increasing Energy Bills: A significant increase in your heating bills could indicate that your furnace is losing efficiency.
  • Inconsistent Heating: Uneven temperatures throughout your home or business could mean your furnace is no longer distributing heat evenly.
  • Strange Noises: Listen for odd noises coming from the unit.
  • Yellow Flame: A healthy furnace flame should be blue. A yellow flame suggests the presence of carbon monoxide, which is a serious safety hazard. If you see a yellow flame, contact a qualified HVAC technician immediately.
  • Dry Air: While not a direct indicator of malfunction, older furnaces can make your indoor air very dry.
It's important to address issues as soon as possible.

Why is my furnace blowing cold air?

Possible reasons for cold air include:
  • Pilot light or ignition problems: If the pilot light is out, the burners won't light, and the furnace won't produce heat. Ignition issues are a common culprit.
  • Thermostat issues: A faulty thermostat can prevent the furnace from turning on or cause it to cycle improperly. Check your thermostat settings to ensure the system is set to 'heat' and the temperature setting is higher than the current room temperature.
  • Overheating: If the furnace overheats, it could activate a limit switch. Overheating can also damage your furnace, so it's best to have a professional inspect the system.
  • Ductwork problems: Seal any ductwork leaks to improve performance. Poorly insulated or leaky ducts can cause a variety of heating issues.
If you're not able to identify the cause and fix the problem yourself, contact a furnace repair professional.

  • Rumbling or vibrating: Check for loose parts or components.
  • Clicking: May be from the igniter, but it can also come from other electrical problems If the clicking sound is persistent, it is best to contact an HVAC technician.
