Furnace and Heating System Repairs 
1-800-Plumber + Air 

Because your furnace plays such an important role in your home, it's only right that there are warning signs before a furnace goes caput. However, it's important to perform regular checks on your furnace and pay attention to how it's running so that you can pick up on these signs and symptoms.

• If you start to notice your furnace is blowing lukewarm or cool air when it's supposed to be warm.

• If your furnace is producing little to no airflow.

• If you start to notice loud or clunking noises coming from the furnace. This could indicate a loose or damaged component.

• If your energy bills start to become unusually high. This could mean that your furnace is running longer than it should be and that there's a problem that should be repaired.

Reasons Your Furnace Might not be Working

Your furnace is a complex machine that has a lot of working parts inside of it. If any one of these parts gives out or isn't working at full capacity, it can cause your furnace not to work.

A Dirty Air Filter

On the side or bottom of your furnace, there's an air filter that acts as a protection against dirt, dust, and other harmful particles from being circulated into your home. If this air filter gets so dirty that it becomes clogged and prevents air from circulating, your furnace will either shut itself down or won't produce enough air to keep your house warm.

The good news about a dirty air filter is that it's something you can fix yourself. To do this, turn the furnace off and remove the air filter. Take it to the store with you and purchase a new one that's the exact same size and dimensions. Install the new filter, make sure to pay attention to the direction arrow on the filter, and install it with the arrow pointing towards the furnace.

A Blown Fuse

Your furnace is a complicated machine that has a number of electrical connections and fuses that help it operate. If one of these fuses gets blown due to a thermostat or electrical malfunction, it will cause your furnace to turn off. Unfortunately, it's difficult to know if this is the problem unless you have the proper diagnostic equipment.

A Clogged or Damaged Vent Pipe

On the top or side of your gas furnace, you should see one or two PVC pipes sticking out of it and running to the outside of your home. If one of these pipes gets plugged or is too long to allow enough air to go to and from the furnace, it will signal an error code and shut your furnace down.

Vent pipe issues are surprisingly common, especially when the pipes are low to the ground when they come out of your home. Because the air coming out of your vent pipe is warm, it's common for birds and small animals to crawl inside to seek shelter. However, the fumes inside the pipe are deadly and can kill the animal inside. This will then cause a blockage that needs to be repaired for the furnace to operate. Snow and debris are also possible culprits in a clog.

A Broken Thermostat

Your thermostat is the control that tells your furnace when to turn on and shut off and controls the temperature in your home. If damage occurs to the thermostat, it could manifest in the form of signals not being sent to the furnace telling it what to do.

Gas or Electrical Problems With the Ignition

If you have a gas furnace that runs on propane or natural gas, there is a pilot on the inside of the furnace itself. The pilot is what starts your furnace up and ignites the flames that help your furnace produce warm air. If there is too much or too little gas flow to the pilot, it will fail to start up. It's also possible for one of the electrical wires controlling the pilot to become frayed or damaged. Either way, your furnace won't turn on and will need to be repaired.

A Broken Fan or Blower Motor

Inside your furnace, there's a fan with a blower motor that activates when your furnace is turned on and forces air through your ducts and out your registers. If the fan or motor that operates it is damaged, it will fail to propel warm air into your home. If you hear your furnace running but don't feel any air coming out of your registers, it's likely that you have a damaged fan.
