Having problems with your heating system can be exasperating, especially if it is leaving you in the cold. One common problem you may encounter is that your furnace keeps turning off. It blows out a little bit of heat but then it shuts off before you get warm. Here are three things you can look into if this occurs.

1. Check Your Thermostat

You may think that since you have not touched it since the last heating season, it should be all right, but go ahead and take a look at it anyway. Does it seem to be working properly? Do the batteries need to be replaced?

Another thing to consider with the thermostat is its location. Is it in a line of direct sunlight? Is it close to a heat vent or in a hot location? The location of your thermostat could be causing your furnace to shut off before all areas of your home have been heated.

2. Check Your Filter

Your furnace needs air to operate. As the furnace produces heat, air brought through it picks up that heat and disperses it. If your furnace is not getting the proper amount of air, the heat exchanger inside it will overheat. Once the furnace controller realizes that the heat exchanger is getting too hot, it will shut off the furnace. After allowing the heat exchanger to cool off, the furnace will restart and run until the heat exchanger overheats again.

Check your filter and replace it if it’s dirty. The filter should be replaced about every two to three months to keep your furnace working efficiently.

3. Contact a Professional Furnace Technician

Sometimes, the fact that your furnace keeps turning off indicates a much more serious mechanical problem. For your safety and the longevity of your furnace, you should contact a professional to assess the situation if you can’t resolve it on your own.

Five-Star Customer Reviews

Excellent service from start to finish. Joe came out to give us an estimate on what we would need for a new furnace, never pressured us to buy the top of their line just giving us options on what we would need for our home. Then the date set for installation Thomas and Ryan came out on time and did a great job.

Evans Mechanical is an excellent service committed to customer satisfaction and guaranteed quality workmanship. Our water heater burst and they were very responsive. They sent a technician out the same day and it was determined the heater was beyond repair.

All three technicians worked well together. They treated each other kindly and were thoughtful and courteous with me. They did a final and complete cleanup after the installment of my new heater. They were respectful of my home. I’m grateful I used this company.
