Common Heating Issues We Fix

  • Ignition problems: Faulty ignition systems prevent your furnace or boiler from starting properly.
  • Pilot light issues: A weak or extinguished pilot light can disrupt heating in gas systems.
  • Strange noises: Clanking, banging, or screeching often point to a mechanical issue like loose parts and should be addressed immediately before further damage is done.

Frequently Asked Questions


That depends on the age of the system, the severity of the issue, and how often it’s breaking down. If your system is over 10 years old, runs up your energy bill, and frequently needs repairs, it may be more cost-effective to replace it.

Use space heaters safely, close off unused rooms, and layer up with warm clothing and blankets. Avoid using ovens or stoves for heat, and make sure to ventilate properly if you’re using a fireplace.

It could be something simple like a clogged filter or incorrect thermostat settings, or it might be a sign of a failing blower motor or ignition system. A professional inspection can pinpoint the cause.
