Trusted Home Furnace Repair Service

The time it takes to resolve your furnace repair problem depends on the location and severity. A dirty flame sensor won’t take much time to resolve, but a more severe problem may require several hours for a lasting solution. Some problems, like a cracked heat exchanger, aren’t even worth repairing over replacing the furnace entirely.

Short cycling is a particularly annoying problem that increases wear and tear from constant heating cycles. The most common culprit is overheating, which in turn is caused by clogged air filters or an issue with the blower motor.

You can even experience short cycling if your furnace isn’t properly sized for your home. Furnaces that are too powerful will quickly generate a lot of heat, tricking the thermostat into thinking the desired temperature has spread evenly through the home.

A faulty thermostat, dirty flame sensor or poor supply of fuel can all lead to your furnace blowing cold air instead of hot air. Clogs in the air filter or drainage system can also force the burners off, leading to cold air. If your furnace is functioning correctly but the heat isn’t making it through your home, it could even be a gap in the ductwork allowing heat to escape.

If your furnace won’t start, there are a few places you can check first. Take a look at the thermostat and circuit breakers to verify the settings are correct. Next, check the air filter, drainage and pilot light for signs of being clogged. In some cases the cause can even be that your furnace is cut off from its fuel supply.

If your furnace keeps turning on and off, there are several potential reasons why. One of the most common is a lack of airflow, which causes the furnace to overheat. Safety mechanisms then shut the furnace down to try and prevent damage. If airflow is the problem, it could be a clogged air filter, supply vent or blower fan.

Furnaces may also repeatedly shut down if the thermostat isn’t working correctly. Wiring problems and dead batteries can cause this problem. The thermostat can also shut the furnace off prematurely if it’s near a source of heat, like strong direct sunlight or a nearby heat register.

Finally, your furnace may keep turning on and off because the flame sensor is dirty or broken. This safety component detects the flame to know when to keep the gas valve open. A dirty or corroded sensor may not detect the pilot light, and mistakenly shut the furnace off.

Despite generating heat, your furnace still produces moisture that needs to be drained away. If the condensation drain is broken or clogged, it can result in a leaking furnace. Because the moisture comes from cooled combustion gases, you can also see a leak if the exhaust/flue pipe isn’t the ideal size for your furnace.

Another possibility is that your whole-home humidification system is malfunctioning. Since your furnace also usually houses your HVAC system’s air handler, humidifiers are installed nearby to ensure efficient airflow.

A more serious concern is if the heat exchanger is cracked or broken. This is an essential component that is difficult to repair. If your furnace is leaking water, the heat exchanger is one of the first places a technician will look.
