It is a good idea to get professional maintenance on your furnace if it is always on and never cycles off.There are three main problems that cause your furnace to short cycle.

The number one reason furnaces run is a dirty furnace filter.The air filter captures dust, pet hair, and debris that could damage the furnace and keep it from getting to the heat exchanger.The heat exchanger gets overheated if the filter is dirty.The fan runs constantly as the furnace goes into cool down mode.If this is the problem, your furnace might start blowing cold air.

Replacing the furnace filter is the solution.If you forget, it is never too late to do this before you start running your furnace in the fall.You should replace your filter every three months.If you own a pet, you should check it about once a month.If there is a shade of brown or gray in the furnace filter, it is time to change it.

New Mexico Air Filter is a great place to buy a furnace filter.They are affordable and local.They can make a special sized filter for you.They can match your old filter if you take it in.

Check your thermostat for the fan setting.The blower will run no matter what the temperature is if the fan is set to on.The blower should only run when the furnace is on.

The temperature on the thermostat should be turned down if the furnace filter is clean and the fan is already set to auto.If the furnace cycles off, give it a few moments.If it is really cold outside, the furnace is running constantly to keep up with the temperature.

The furnace needs to be derated.What is derating in the world?The gas pressure is adjusted to match the elevation.The furnace ends up overheating if it is not set correctly.

The furnace runs, and with the gas pressure not adjusted, it gets too hot.The fan keeps blowing as the furnace shuts off.The furnace will switch on and off constantly, with the fan never stopping.If you think this might be the problem, you need to call a professional.Don't try to do it yourself, it requires a pro.

If the issue continues after you tried the suggestions, it could be ghosts.We are joking!If the thermostat is set correctly and the filter is clean, it is time to call a heating professional.Did you think we were going to say Ghostbusters?

A lack of maintenance is almost always to blame for a furnace that runs constantly.Most emergency furnace repairs can be avoided if you change your filter and get an annual furnace inspection.It is easy and stress-free to maintain with the Preventive Maintenance Program.
