Common Problems With Home Heating Systems

We Can Help You Understand What’s Wrong & How We Can Fix It

Service Champions would rather educate our customers than pressure them into a sale. Some companies might try to impress you with knowledge and a superior attitude, but we prefer to consult with you and answer all your questions.

This page has some basic information to help you understand some of the things that can go wrong with a home’s heating system.

Common Furnace Problems

A traditional home furnace operates with natural gas. When the mechanics inside of your furnace malfunction, there are a variety of reasons why your furnace may fail to provide heat.

In this example, our technicians were out on a call and came across a health danger for the home that owned this furnace. As you can see, the heat exchanger (also known as the fire box) had a hole on it. The danger with this gas furnace is that CO2 (Carbon Dioxide) was leaking out of the heat exchanger coils. Needless to say, it was not providing as much heat as a fully functional furnace should.

When the gas valve is stuck or does not open, there is no release of gas to fuel the furnace burner needed to provide heating. Another common reason for furnace problems is if the ignition system breaks down. The spark ignition, related to the gas valve, may not work.

Control Board and Safety Controls

The control board inside of your furnace is what allows you to adjust the temperature of the inside of your home from the thermostat.

The control board oversees the entire function of the furnace including heating and air conditioning. When there is internal failure, the entire board is replaced. Here is an examples of a damaged control board we have seen.

A problem in your furnace’s air flow can automatically shut down the furnace from producing heat as a safety precaution. When the furnace overheats or detects other dangers such as flame roll-out, the limit switch turns off the furnace. In order to protect your family and home, it is important that the limit switch is always working.

Inoperative Blower Motors

In order to move heated air from one place to another, your central air system relies on a small network of motors. These motors are essential in moving unconditioned air through the furnace and into your home. When these motors fail, the low air flow causes even less air to enter which means less heating for your home.

Clogged Blower Wheel

Blower motors fall into disrepair for a few different reasons: the wheel on which the motor spins gets damaged, the venting system from the blower clogs or corrodes or the pressure safety fails. The picture above is an example of a recent clogged blower wheel and below is the result after our technician got his hands on it.
