If you hear a hissing, lose hot water, or find that your house isn’t heating up like it used to, you probably have a boiler issue on your hands. So, who do you call to fix your boiler? Well, the local professionals in your area may label themselves slightly differently according to their primary business, but a boiler repair and installation service will know exactly what to do. Make sure you hire a pro licensed to operate a boiler and years of experience. This could be a plumber, an HVAC technician, or—ideally—a specialized boiler repair pro. 

Why It’s Best to Hire a Boiler Repair Pro

These technicians are considered specialists for several reasons. Here are a few of them. 

Safety Precautions

Boilers burn fuel to generate heat. That’s part of why they’re one of the most dangerous appliances in your home, and tinkering with them risks some extreme consequences. Professionals licensed to repair and operate boilers understand the important health and safety precautions to take before investigating or repairing it so that no one is at risk of harm—not even your house.

Expert Diagnosis

This one’s a no-brainer. You may think you know everything you need to know about your home, but a boiler is a complex beast. Professionals can determine what’s gone wrong and how to fix it better than any average homeowner or handyperson. 

Access to Correct Parts (Quickly) 

Maybe you need to heat your home before a big freeze or get the hot water running again ASAP. If you’re on a tight deadline (which most people are), purchasing and receiving the parts for your boiler repair can be your biggest challenge. Professionals will often have them on hand or have access to them quickly through their industry, getting the job started much sooner than you can do on your own. 

Angi Tip

Get your HVAC system serviced and inspected at least once per year. For extra peace of mind, call in a pro twice annually: once before the hottest months of the year and again before the coldest time of year.

Can I DIY Boiler Repair?

It might be tempting to save yourself about $400, which is the average cost to repair a boiler. But the truth is, DIYing your boiler repair isn’t just a bad idea—it’s dangerous. Boilers are complex systems that involve a lot of heat and fuel, so one wrong move could create unexpected combustion. It’s best to hire a local boiler repair pro for any boiler service, repair, or installation. 

That said, there are some easy DIY boiler maintenance tasks you can do on your own to make sure your system is running smoothly each year. Inspecting the vents, chimney, and pipes can help you spot any issues you need to call a pro about. You can also lubricate the circulating pump with oil, replace or clean the filters, and reset the pilot light on some models.

Some people have experience with boilers through other services they provide, like HVAC installation or general home maintenance tasks. But unless this person is specifically licensed to work with boilers, you don’t want them around yours. The biggest reasons are the safety risks it poses, the liability you may face if they injure themselves, and the fact that only a professional boiler service can complete the service from start to finish properly.

How Does a Boiler Repair Technician Fix My Boiler? 

Your boiler tech will begin by entering your boiler room, investigating the unit, and discussing any issues with you. After that, they’ll make the necessary repairs (either in the same visit or a second one) until the project is complete and you have everything you need. 

Since there are usually two types of boiler repair pros, this may come from a plumbing company or an HVAC company. Plumbers are licensed to work on boilers, but they mainly focus on their water disbursement. That means fixing leaks, unusual noises, pressure fluctuations, and pilot lights. An HVAC technician would be able to inspect the entire system for issues, which covers everything under the umbrella of your home’s heating and cooling systems.
