A gas furnace needs a lot of air to efficiently use the heat exchanger. It’s the heat exchanger than turns cold air into warm air. When the air filter is dirty, there isn’t enough air in the system and the heat exchanger overheats. The furnace shuts off the burners and turns on the cooling fans to reduce the temperature of the heat exchanger. When the system is cooled it attempts to fire up again. However, because the air filter hasn’t been cleaned or replaced, the same thing happens again. Manufacturers limit the number of times this can occur. Usually after four attempts, the furnace will not restart until it has been serviced.
Repeated overheating of the heat exchanger can also damage the high-limit switch. This is a simple furnace repair in Houston, TX for the technician. He will simply remove the retaining screws and pull it out of the heat exchanger. He will take a new one from the service van and easily replace it. Homeowners should watch the technician replace or clean the air filter. During peak heating season, the air filter should be changed at least once a month.
Regular maintenance can reduce many emergency visits. In addition to making sure that the air filters are clean, the technician will look for any frayed belts or corroded sensors. Business Name. is one of the companies that repairs furnaces in the Houston region.
