8 Most Common Reasons Furnaces Break Down

A furnace that stops working can be a significant setback for any homeowner. There are many possible reasons why it might stop working but the good news is that there are just as many fixes that can get it up and running again quickly. You can try solving the problem or reach out to emergency furnace repair at The Chill Brothers in Spring, Tx.

Faulty thermostat

A furnace thermostat is a device that senses the temperature and turns on and off the blower to maintain it at the desired level. The thermostat can have a slight malfunction or be mis-programmed which won’t allow it to turn on or off. Test the thermostat first by moving it to a higher temperature and seeing if the furnace comes on. If it does, then the problem is in your wiring.

If your thermostat is digital, check the battery and make sure to replace them with new ones. If the thermostat is mechanical, clean it with a dry cloth and see if this solves the problem. Also, if you have a programmable thermostat, check and make sure you’ve set it correctly.

Clogged vents

A clogged vent is a common cause of furnace leaking water in summer. Blocked vents cause the furnace to overheat and shut down. The air that the furnace sends out will also be much less warm, making your home feel cold. Clogged vents may be caused by animals, birds, or even a bird’s nest. The best way to solve clogged vents is by hiring a commercial HVAC company instead of cleaning them on your own.

Aged unit

When a furnace is more than 15 years old, problems often begin. Old equipment must work 2 to 3 times harder to keep running thus producing less efficiency and higher energy bills. Troubleshooting an ageing furnace is not as hard as you might think. During furnace installation, make sure to check that it has enough air and fuel supply by checking the burner and the venting system.

For better results, if you are in Tomball, Texas hire the professional HVAC service provider, The Chill Brothers, for the furnace repair. Our experts will check for any problems or damaged parts that might be causing your heating system to stop functioning correctly.

Faulty fan motor

This part is responsible for circulating air inside your home’s ductwork. It can burn out if there aren’t enough filters to catch dust and dirt or if the unit isn’t installed correctly or wasn’t adequately vented, to begin with.

Dust and Dirt Buildup

A furnace operates by burning fuel and air to heat the home. When you have an older furnace, the blower fan needs to work at high speed to pull enough air through the heating unit to burn fuel and make the house warm.

The faster a fan operates, the more it picks up dust and dirt from home, making it dirty and clogged with debris. This slows down the efficiency of the blower motor, which causes undue stress on your furnace and results in increased energy bills.

Broken blower wheel

The blower wheel moves air through your vents and pulls it through your house via its connection with the intake vent. If this wheel becomes dirty or cracked, its ability to move air is reduced, which puts additional stress on your furnace’s ability to maintain a comfortable temperature inside your home.

Faulty wiring

Almost every furnace contains a pressure switch, which turns the unit on and off. If you see a small red or yellow light glowing next to your thermostat, you may notice this switch. If the switch continually gets tripped, there could be an issue with the wiring, causing the furnace to turn on and off repeatedly. This can lead to overheating and eventual failure of the unit.

Faulty heat exchanger coils

These are located in the furnace’s blower compartment and are responsible for distributing heat throughout your home’s ducts. They can burn out if they aren’t adequately insulated or if they get too much exposure to air from outside of your home (e.g., from an improperly installed vent).

When the furnace stops working, it can be a real pain. Even worse, if you don’t take immediate action, you could end up with thousands of dollars in costs to repair or replace the system. Make sure to get your furnace repaired by the professionals from The Chill Brothers, a reliable and experienced commercial HVAC Company.
