Common Furnace Repairs: What Homeowners Need To Know
Furnaces are an essential part of most homes, providing warmth during cold weather. However, like any other mechanical system, furnaces can develop problems that require repair. Here are some of the most common furnace repairs that homeowners may encounter.
Dirty or clogged filters
A dirty or clogged furnace filter can cause a variety of problems, including reduced efficiency and overheating. A dirty filter can also lead to poor indoor air quality. Homeowners should check their furnace filters regularly and replace them when they become dirty.
Pilot light problems
If the pilot light goes out or won't stay lit, it can be a sign of a faulty thermocouple or a clogged pilot orifice. The thermocouple is a safety device that detects whether the pilot light is on or off. If it senses that the pilot light is off, it will shut off the gas valve to prevent gas leaks. A technician can clean the pilot orifice or replace the thermocouple if necessary.
A faulty thermostat can cause a furnace to turn on and off frequently or not turn on at all. In some cases, the thermostat may need to be calibrated, while in others, it may need to be replaced. Homeowners should ensure that their thermostat is installed in a location that accurately reflects the temperature of the room.
Blower motor problems
The blower motor is responsible for circulating air through the furnace and into the home. If the blower motor stops working, the furnace may overheat or shut down. A technician can inspect the blower motor and replace it if necessary.
If a furnace won't ignite, it could be due to a faulty ignition system or a lack of fuel. In some cases, the pilot light may be out, or the gas valve may be closed. A technician can diagnose the problem and make any necessary repairs.
Cracked heat exchanger
A cracked heat exchanger can be a serious problem, as it can allow carbon monoxide to leak into the home. Homeowners should have their furnace inspected annually by a technician to ensure that the heat exchanger is in good condition.
While some repairs can be done by homeowners, others should be left to a professional technician. Homeowners should have their furnace inspected annually to prevent problems and ensure that it is running efficiently.
In some cases, homeowners may need to consider replacing their furnace rather than repairing it. If a furnace is more than 15 years old, it may be less efficient and more prone to breakdowns. Additionally, if a furnace requires frequent repairs or the cost of a repair is more than half the cost of a new furnace, replacement may be the more cost-effective option in the long run. A professional technician can help homeowners determine whether repair or replacement is the best course of action for their specific situation.
