Repairing Gas Furnaces: Common Issues and Solutions

Gas furnaces heat enclosed living spaces with propane or natural gas. While gas is frequently portrayed as an expensive source of heat, gas furnaces burn cleaner than oil furnaces and require fewer repairs. When problems do arise with gas furnaces, though, they’re usually easy to spot and fix. The following are four frequent problems with older gas furnaces, as well as what you may expect in terms of repairs.

There is no heat produced by a furnace.

If your gas furnace isn’t producing heat, it’s most likely due to a closed control valve, a blown fuse or tripped circuit, a defective thermostat, or a non-functioning pilot light. While you could fix these issues yourself, if you aren’t familiar with gas furnaces, it’s advisable to call Gas Furnace Repair Scarborough (i.e., a heating and cooling business). Regardless of which of the above problems your furnace is having, an HVAC repair specialist should be able to remedy it the same day, and none of the problems will cost a lot of money to correct.

Insufficient Heat is Produced by a Furnace

It’s possible that your furnace is producing less heat because the blower is clogged, the blower belt is loose, or the filter or burner is unclean. These issues can potentially happen at the same time. A furnace that provides insufficient heat as a result of one of the foregoing faults may typically be remedied the same day at a low cost, just like a furnace that produces no heat. If a gas furnace repair professional says the problem is caused by one of the above problems but that some of the others are on the way, save money and have them all fixed in one visit.

A Furnace Is Constantly Turning on and Off

Your furnace is most likely suffering from a blocked blower, a dirty filter, or an overly dry motor if it turns on and then turns off before delivering the desired degree of heat. In the first case, a technician will vacuum the area around your blower; in the second case, the technician will replace your temporary air filter or clean and reinsert your permanent air filter; and in the third case, the Gas Furnace Repair Scarborough technician will lubricate the motor by placing oil in the necessary oil ports. In each situation, the service fee should be kept to a bare minimum.

The Pilot Light on a Furnace Won’t Turn On

If the pilot light is on, you may tell by kneeling on the floor and looking at the underside of the furnace, where a faint blue flame will emanate from a small pipe if the pilot light is on. A clogged pilot opening, insufficient gas flow owing to an improperly set gas valve, or a faulty thermocouple are the most common causes of a pilot light that won’t light. In each case, the solution necessitates only minor labor and may be completed at a low cost.
