Our technicians are factory-trained, certified, experienced, and skilled at troubleshooting and fixing all types of heating problems. We will evaluate your system to identify the source of the problem, recommend the most efficient and cost-effective repair, ongoing heating maintenance, and get your heat restored as quickly as possible for your family’s comfort and safety.

What are the Signs You Need Heater Repair?

There are several common signs that indicate that your heater may need repair:

  • Lack of Heat: If your heater is running but not producing enough heat or no heat at all, there could be issues with the heating element, thermostat, or other components.
  • Strange Noises: Unusual noises such as banging, rattling, squealing, or grinding could indicate problems with the blower motor, bearings, or other internal components.
  • Frequent Cycling: If your heater turns on and off frequently (short cycling), it may be struggling to maintain the desired temperature due to issues like a faulty thermostat or restricted airflow.
  • Weak Airflow: Reduced airflow from vents could be caused by a clogged air filter, blocked ducts, or issues with the blower motor.
  • Strange Smells: Unpleasant odors like burning, musty, or rotten egg smells could indicate electrical problems, mold growth, or a gas leak, which require immediate attention.
  • Visible Damage: If you notice visible damage such as cracks, rust, or corrosion on your heater, it may indicate wear and tear or more serious issues that need repair.
  • Increased Energy Bills: Experiencing a sudden spike in energy bills without an increase in usage could be a sign that your heater is operating inefficiently from underlying issues.
  • Thermostat Malfunction: If the temperature settings on your thermostat do not match the actual temperature in your home or if the thermostat is unresponsive, it may need repair or replacement.
  • Pilot Light Problems: For gas-powered heaters, if the pilot light frequently goes out or appears yellow instead of blue, it could indicate issues with the burner or gas supply.
  • Age of the Heater: If your heater is nearing the end of its expected lifespan (typically around 10-15 years for most systems), it may require more frequent repairs or replacement.

If you notice any of these signs, it's essential to have your heater inspected and repaired by a qualified HVAC technician to prevent further damage and ensure efficient operation.

What To Do If Your Heat Is Not Working?

If your home's heating system is not working, this does not necessarily mean it is broken. There are a couple of troubleshooting steps that can be done before calling an HVAC specialist. Some steps you can take to ensure your home's heater is working properly are:

  • Make sure your home's thermostat is set to heat
  • Change the filter in your heater
  • Make sure the gas is on
  • Clear the chimney exhaust flute
  • Clear debris from the external exhaust vents
  • Check for blocked ducts that could restrict airflow

If after taking those steps your heater is still not working, give Farnen & Dermer a call. Our team of experts will assess the problem and make your home's heat repair or heater replacement as smooth as possible. We'll ensure your home's heating system will continue to work for years to come.

What Do I Do If My Heater Is Blowing Cold Air?

When your home's heating system blows cold air, the first troubleshooting step is to turn the unit off and on again. After that if the air feels warm for a moment or two, then switches to cold, it may be due to the flame sensor becoming dirty. With a dirty sensor the gas burner won't stay lit. If you have a dirty flame sensor, or any problems with your home's heating unit, contact the HVAC specialists at Farnen & Dermer today.
