5 Common Furnace or Heating Repair Scenarios


Winter brings with it the hassle of repairing your home furnace. Before November, you may have seen one or two problems with the heating system. Ideally, learn why you need a local heating and air expert to visit you. Learn about 5 problems that are common causes for furnace or heating repair.

Faulty Thermostat

The main problem is a thermostat that does not turn on at all. There are some thermostats that switch on and off, resulting in erratic fluctuations of the temperature. If the repairs do not work, an HVAC professional may tell you that you need a replacement.


Clogged Filter

If you're not circulating enough heat in the house, the problem could go beyond the thermostat. Check if the air filter is clogged. To avoid this problem, review and replace this filter at least once a year. Depending on its usage, you may need to replace it more often.

Reduced Airflow

A clogged filter is one cause of poor airflow, and so is a broken fan or motor. During winter, the coils could freeze or snow could block the air vents. A technician looks at all of these parts in order to improve air circulation.

Ignition problems

An electronic ignition failure is caused by a faulty wire, a dirty flame sensor or an open switch. When you cannot ignite the pilot, the heat does not turn on or turns on erratically. There could also be an underlying problem with your home's electrical system.

Insufficient Maintenance

Not maintaining your HVAC system is the main cause of any malfunction. A heater needs the same amount of maintenance that a car or house does. Replacing the filter is necessary to remove clogs that form inevitably on your heater. You need to check the other parts to prevent sudden breakdowns. Maintain your furnace once a year to avoid paying high energy repair bills.

Trying to fix heater problems yourself is time-consuming and could be a waste of time. In many repair scenarios, the problems cannot be fixed, and a professional has to make a replacement.
