While costs depend on several factors, we can somewhat generalize what you can expect based on the industry. In the U.S., boiler repair costs typically range between $180 and $620. A few cost determiners include major boiler features and other elements, such as:
Danger aside, you would void your boiler warranty, making what could be a less expensive repair much more costly. Warranties usually cover replacement part costs for around five to 10 years.
Homeowner’s insurance can even cover some or all of the boiler service depending on what caused the malfunction.
Of course, these possibilities don’t mean you have to trust any and every plumber you come across. Instead of a DIY try, you can personally investigate local plumbing companies to help you find the best one.
