Waukesha boiler repair service 5 star review

"Prompt Heating and Air Conditioning owner Ty came immediately from his last job to our home, and arrived within 30 minutes. We came home tonight to a cold house, and since we have a baby, it was important to get a diagnosis quickly. Ty zeroed in on the problem immediately and even had the part we needed on his truck. He fixed everything in about 30 minutes and we had heat again! I am so grateful someone recommended Prompt to me, and I will recommend him to others."

Boiler Repair Frequently Asked Questions FAQ

Have a Question? Contact Us

How much does it cost to fix a boiler?

A boiler needs to be inspected to diagnose the problem. Price is a chief concern when you need boiler repair, and you’ll never get surprise costs with Prompt. We’ll give you a fair, firm price before getting to work.

Should I repair or replace my boiler?

The first consideration is the boiler's age. On average, a residential boiler lasts 15-20 years, depending on how often the boiler was professionally serviced and maintained. If you suspect your boiler needs replacing, get it inspected by a professional to make sure the boiler meets modern safety standards. If your heating bills and boiler repair costs increase year after year, you might be better off replacing your boiler with a more efficient unit. Give us a call and we’ll come take a look!

Why is my boiler leaking water?

Your boiler may have been installed incorrectly. Other causes of leaking boilers include corroded pipes, valves or tanks, excessive mineral residue causing pressure buildup, and worn seals around the boiler pump. In some cases, the pump itself is damaged. As time passes, boilers can also develop stress fractures, which can cause leaks to develop.
