Is your heating and air conditioning system on the blink?

Troubleshooting Furnace Problems

Heating and air conditioning systems can be a bit of a mystery to the average homeowner. When something goes wrong it can be difficult to determine what the cause could be. What do you need? You need a helpful heating and air conditioning system troubleshooting guide to help you figure out why your furnace isn’t working correctly. At Helms, we’re here to help.

Problem: No warm air, though the heat is on.

Tip: Check the filter.

If your air filter gets dirty, the air has trouble passing through it, preventing enough warm air from reaching the rooms in your home. Not only does this keep your house from reaching your desired temperature, but it also makes your furnace overwork.

Problem: Warm air is not blowing out of the furnace.

Tip 1: Check the thermostat.

It's easy to set your thermostat wrong by a few degrees. Check the thermostat to be sure it’s set properly.

Tip 2: Check the power to the breaker.

Make sure the fuse isn't tripped and there is power to the thermostat and the furnace.

Tip 3: Check the pilot light.

If you have a gas furnace, check to be sure the pilot light is on and the gas valve is open.

Problem: Furnace cycles on and off frequently.

Tip: Check the belt.

Adjust the tension if it's too loose and examine the condition of the belt to be sure it's not torn or cracked.

Problem: Noisy furnace.

Tip 1: Check the burners.

If the burners are dirty, they'll need to be cleaned.

Tip 2: Check the pilot light.

A noisy furnace could be an indicator that the pilot light needs adjustment.

Tip 3: Check the belt.

If the belt is loose or shifting, it could be causing your furnace to be noisier than usual.
