When the temperature outside drops, the last thing you want is for your heating system to stop working. If you’re dealing with heat not blowing, a furnace not working, or your entire heating system not functioning, it’s crucial to know the steps to restore warmth. Here’s what to do if the heat goes out and when to call for professional heating repair.
Immediate Steps to Take When the Heat Stops Working
1. Check Your Thermostat
The thermostat is often the first culprit when you notice your heat not working in the house. Ensure it’s set to “heat” mode and that the temperature is set higher than the current room temperature. If your thermostat is battery-operated, replace the batteries to rule out a simple fix.
2. Inspect Your Power Supply
A heater not working could be due to a tripped circuit breaker or a blown fuse. Check your home’s electrical panel to ensure the circuit controlling your heating system is on. If it has tripped, reset it, and see if that restores the heat.
3. Examine Your Furnace or Heat Pump
For those with a furnace, check if the pilot light is lit. If it’s not, relight it according to the manufacturer’s instructions. If you have a heat pump, ensure it’s not in defrost mode, which can cause temporary heat loss.
4. Replace Air Filters
Clogged or dirty air filters can restrict airflow, causing your furnace to overheat and shut down. Replacing the filters may resolve the issue and get your heat blowing again.
5. Look for Obvious System Alerts
Many modern heating systems have diagnostic lights or error codes. If you notice blinking lights or a display code, consult your system’s manual to understand what might be wrong.
Common Reasons for Heat Not Working
1. Fuel Supply Issues
Gas or oil furnaces rely on a steady fuel supply. If your gas line is interrupted or your oil tank is empty, your furnace won’t work. Contact your fuel supplier to confirm there are no issues.
2. Frozen Pipes or Components
During extreme cold, pipes or outdoor heat pump components can freeze, causing your heating system to stop functioning. If you suspect frozen pipes, shut off your system to prevent further damage and allow the components to thaw.
3. Blower Motor Failure
The blower motor is essential for circulating warm air throughout your home. If the motor fails, you’ll notice your heat not blowing even though the system appears to be running.
4. Thermostat Malfunctions
An older or faulty thermostat may not properly communicate with your heating system, leading to heat not working in the house. Replacing the thermostat may resolve this issue.
5. Pilot Light or Ignition Problems
If your furnace relies on a pilot light or electronic ignition, problems with these components can prevent the furnace from working. Dirt buildup or mechanical failure often causes these issues.
When to Call for Heating Repair
If you’ve taken the steps above and your heat is still not working, it’s time to call for professional heating system repair. Some problems require the expertise of a trained technician, especially if they involve:
- Electrical issues
- Fuel supply problems
- Malfunctioning internal components
- Persistent system shutdowns
A professional can quickly diagnose the root cause of your heating issues and ensure your system is restored to full functionality.
Tips to Prevent Heating Failures
1. Schedule Regular Maintenance
Annual heating system tune-ups can help identify and fix small issues before they become major problems. Maintenance also ensures your system runs efficiently, which can extend its lifespan.
2. Change Filters Regularly
Replacing air filters every 1-3 months keeps airflow unobstructed and prevents overheating.
3. Upgrade Old Equipment
If your furnace or heat pump is over 15 years old, consider replacing it with a modern, energy-efficient model. Newer systems are less prone to breakdowns and can save you money on utility bills.
4. Seal Your Home
Drafts and poor insulation can overwork your heating system, leading to potential failures. Sealing windows and doors and improving insulation can reduce the strain on your heater.
