How Does A Contractor Diagnose Furnace Problems?

You wake up to a cold house and wonder why your heat isn't keeping up. After checking your thermostat, you realize that your furnace isn't working.

If this ever happens to you, you'll want to contact a heating repair company right away. First, you'll need their services to determine the problem. Then, the heating contractor will fix the issues after diagnosing the issues. Most heating contractors diagnose issues by completing a few steps.

Check the thermostat

A furnace expert often begins by checking the thermostat. First, they might check to see if it's turned to "heat." If not, this might be the issue. Next, they'll adjust the temperature to see if the furnace turns on. They might also use electrical testing equipment to ensure there is power to the thermostat. If none of these steps fix the issue, they'll move on to the next step.

Examine the furnace 

Furnace repair technicians examine the furnace next to see if they see any visible problems. They might check to see if the power is on at the furnace. They might also check the air filter to see if it's dirty or clogged.

Look at the power supply

Additionally, they will look at the power supply and check the breaker panel. If the furnace breaker isn't on, they'll turn it on. Breakers can blow for various reasons, but if your furnace breaker blows, your furnace won't run. Therefore, it's important to check this component during a furnace inspection.

Examine the main components of the system

If the furnace technician hasn't located the problems yet, they will begin examining each important furnace component, beginning with the pilot light. Most furnaces have a small light located near the floor. This light must be on for the furnace to turn on and produce heat. If it's off, they'll light it. This step might fix the problem.

There are situations when pilot lights won't stay lit after lighting them. If this happens to be the circumstance, they will determine the cause and make the necessary repairs. The technician will check a variety of other parts during this assessment and will eventually locate the problem.

Fix the issues

A heating contractor will find the problems and make any repairs the system needs. Afterward, they'll test the system before leaving your home. When you need furnace repairs, contact a company that offers them in your city to get your system running quickly.
