Thinking about DIY’ing your furnace repair? Think again.

Danielle Onat | 12/07/2016 | Posted in Heating

In a world of Pinterest surfing and YouTube tutorial watching, DIY is everywhere. You decorate your home entirely in pallet wood and mason jars, fix your overflowing dishwasher, and install your own tile floors. Homeowners have more tools than ever when undertaking home improvement if they simply have three minutes to watch a video or read a blog. And while many home improvement tasks are wise to DIY, furnace repair isn’t one of them. Here’s why.


It’s just not safe.

Unsurprisingly, this is the number one reason not to repair your own furnace, as doing so can have major safety and health ramifications. If your furnace is powered by natural gas, improper repair can lead to dangerous leaks that can expose your family to toxic fumes and the risk of explosions. Electric furnaces can shock you during wiring work. Later on, you won’t know if it is working safely, as a gas-powered furnace could slowly leak carbon monoxide and an electric furnace could cause a fire due to faulty wiring.

Washington Energy Services technicians use their years of experience to repair and maintain your furnace, checking and re-checking all possible safety concerns. Put simply, it’s an assurance of safety for your family.

It can void your warranty and cost more in the end.

Warranties are great—when they aren’t voided. One of the ways you can void a warranty is to install or repair a furnace yourself. Many manufacturers require that only trained professionals repair their equipment in order to uphold the warranty. Consider this: to save money, you repair the furnace yourself (despite the safety risks). A month later, the furnace breaks, but you are not covered under warranty because you did not have a professional fix the equipment. You then must pay for a new furnace, installation, and ongoing maintenance. It’s a risky proposition.

It’s complicated and requires specialized tools.

This one is simple—furnace work is complex. Successful repairs require precise measurements and a solid understanding of electrical components, gas lines, ductwork, sheet metal work, and more. Special tools not typically found in the weekend warrior’s tool belt are also required.

Even though DIY furnace repair isn’t a good idea, there is one key maintenance task you can undertake to ensure proper operation of your furnace: changing your air filter on time, every time. Check out last week’s blog article to learn more about the benefits of consistently changing your air filter and our Automatic Filter Replacement Program.

So while we encourage homeowners to learn the inner workings of their home and take on money-saving projects, furnace repair is just something that’s best left to the professionals. It’s a matter of safety, peace of mind, and of course, comfort.

    Thanks for covering such an important topic!
    Many people first try to fix the furnace themselves, and then it turns out that it was a breakdown due to the fault of the manufacturer. And the warranty has already been voided…

    Hello there, thanks for sharing! You’re right, sometimes it’s better to hire a qualified electrician. However, there are situations one can handle without professional help. For example, if your pilot light has gone out, gas will not feed into the burner, even though all other systems in the furnace are functioning properly. If so, all you will need to do is re-light it. To get more information about it you can check our guide to DIY furnace repair, hopefully, it will be useful to your readers: https://www.escoutah.com/quick-guide-performing-furnace-repair-utah/

    I had no idea that doing your own repairs could void your warranty. That sounds awful and expensive. I’d rather keep my warranty and pay someone else to handle repairs.
