My Furnace Runs Constantly

The winter months in and around Arlington, Centreville, Reston, and all throughout VA can produce temperatures in the low teens (and even below), which means homeowners should really start focusing on furnace maintenance. As one of the top Virginia furnace replacement service providers, one of the most common complaints we hear from our customers is that their furnaces run constantly—don’t worry, we can help you fix this common furnace problem.

When a furnace runs constantly, it probably means that something is dirty or clogged. The filter is the first thing you want to check, especially if you do not replace your filter as often as recommended (once a month during the heating season). Not only does a dirty air filter force your furnace to work harder than it really needs to, which causes it to function inefficiently and can cause the heat exchanger to crack and leak carbon monoxide into your home—a deadly situation.

If the air filter is good to go, lower the temperature on the thermostat. If the furnace continues to run, shut the heating system down completely. If your thermostat is set to a high temperature or if it’s very cold outside, the furnace might be running just to keep up with the thermostat’s demand for heat. But if the furnace fan continues to blow, there could be an electrical problem between the thermostat and the furnace or air blower, which requires a professional repair.

If you’d like the help of a heating professional, give John Nugent & Sons a call at 703-291-1926. You’ve got questions, we’ve got answers. When it comes to resolving furnace problems quickly and efficiently—we’re the experts.

Contributing Factors for Common Furnace Problems

Some other problems that may cause a furnace to run constantly include a clogged furnace blower or a furnace blower/motor that needs lubrication—both of these issues will force your furnace to work ineffectively. Also, be sure to check that the fan switch on your thermostat is set to AUTO, not ON.

As we approach the colder months, it’s very important you have a properly functioning heating system that heats your home throughout the winter. Today’s HVAC systems are complex, and experienced, well-trained electricians are best qualified to diagnose and repair furnaces. If you have a furnace that runs constantly and can’t seem to figure out why, please contact us.
