What Are The Most Expensive Furnace Repairs?

As a homeowner, you want to ensure that each morning when you wake up, the furnace is running properly. Unfortunately, no matter how well you care for your furnace, including scheduling regular maintenance, most components inside your furnace will need to be replaced at some point. Here are a few of the most expensive furnace repairs, and what you can do to avoid them.

Blower Motor

The furnace's entire blower motor is made up of several components, including the motor itself, a set of fan blades found in a large metal cylinder, and the electrical parts that power the motor. The blower motor has an important job: It helps draw air into the furnace. If there is no positive airflow into the furnace, it will not work properly.

In some cases, a single component might break, meaning the other two are still viable. The repair becomes more expensive when you must replace all three.

Draft Inducer Motor

Another critical component of your furnace, the draft inducer motor helps remove any harmful gases that are built up in the furnace. The inducer motor is typically found in the upper section of the furnace and is located near the heat exchanger.

When the heating cycle kicks on, the inducer motor turns on before the furnace burners are lit. If you have a faulty draft inducer motor, your furnace will not light and will shut off before the heat cycle can begin.


The thermostat is found centrally in your house and controls the temperature. If your thermostat breaks, it can be very expensive to replace, especially if you have a newer, state-of-the-art model that can be controlled by your smartphone, tracks your energy usage, or can be integrated into your smart home controls.

Circuit Board

To put it simply, the circuit board is basically the brains of your furnace. All of the electrical components on the furnace cannot function properly without a working circuit board. Be aware that if your circuit board fails, it can be tricky to diagnose. This is why you should leave this problem to the professionals.

How to Avoid Costly Furnace Repairs

Luckily, there are several things you can do to extend the life of all your furnace components. Change the air filter regularly, sign up for a yearly inspection, and contact a professional HVAC technician at the first sign of an issue.

From the inducer motor to the circuit board, there are several furnace repairs that can drain your wallet.

About Me

cool and hot areas of the home

I live in an older home that we are working to renovate. There are three areas of the house that just don't seem to get cool in the summer or get warm in the winter. I have done all that I can to try to keep these areas comfortable, but I wasn't able to do much until I hired an HVAC technician to come out and figure out why those areas were so uncomfortable. This blog will show you what can be causing areas of your home to be less comfortable than other areas when it comes to temperature during both winter and summer.
