When your cold climate heat pump stops working while family is over for the holidays or your secondary heating system breaks down when you least expect it to, it's awfully tempting to try fixing it on your own if you want warmth back as soon as possible.

While there are some situations where you can solve the issue by yourself, there are many circumstances where it's smarter and safer to entrust the repairs to a professional. If you're interested, here's an overview of heating repairs that fall under both umbrellas!

Some Heating System Problems Can Be Fixed DIY

  • Dirty Air Filter: If airflow feels weak or the HVAC system starts blowing cold air, check for a dirty air filter. A clogged filter can strain the furnace or air handler and limit airflow. You should replace the air filters every one to three months to keep your system running smoothly.
  • Tripped Circuit Breakers: If the heating system suddenly stops working, reset any tripped breakers in your home's electrical panel.
  • Blocked Vents and Air Ducts: If some rooms remain cold, check for obstructions in vents or air ducts. Consider moving furniture and clearing debris to allow better circulation of heated air.
  • Improper Blower Fan Settings: If the HVAC system runs without producing heat, ensure the blower fan is set to “Auto” instead of “On” to avoid continuously blowing cold air.
  • Outdoor Heat Pump Unit Blockages: During winter, ensure your outdoor heat pump unit remains clear of snow, ice, or debris to help it operate more efficiently.

However, Complex Heating Issues Should Be Left to Professional Technicians

  • Cracked Heat Exchanger: A cracked heat exchanger or cracked secondary heat exchanger in a gas furnace can leak dangerous gases. Only a professional HVAC technician can safely diagnose and replace these components.
  • Faulty Gas Valve: If the gas valve fails, the furnace cannot combust heating fuel properly. Professionals must inspect and repair or replace it to restore safe operation.
  • Malfunctioning Blower Motor: When airflow stops despite the system running, the blower motor may require a technician’s attention to restore proper operation.
  • Air Pressure Switch Problems: If the furnace repeatedly shuts down, an air pressure switch malfunction may be preventing proper ignition. Call a professional to have this part tested and repaired.
  • Boiler or Furnace Ignition Failures: Persistent startup issues involving hot surface ignitor elements or ignition systems require advanced troubleshooting that homeowners should not attempt.
  • Heat Pump Refrigerant Leaks: If heat pumps extract warmth inefficiently or you notice hissing noises, a refrigerant leak may exist. A technician must locate and seal the leak.
  • Heat Exchanger Cracks in Furnaces: High-efficiency condensing furnaces are prone to heat exchanger cracks. Routine inspections ensure these dangerous issues are caught early.
  • HVAC Installation: Issues related to improper HVAC installation or worn HVAC equipment require professional help to fix by means of a reinstallation or complete replacement.
  • Automatic Damper System Issues: If an automatic damper system malfunctions, heated air may not distribute evenly throughout the home. HVAC technicians can repair the system for better airflow.
