Reliable hydronic heating system repair
We work on all different types of boiler heating systems including hot water boilers (the most common type), steam boilers (less common), and combination (combi) boilers that provide both heat and hot water.
Numerous companies had been called in the past and their general consensus was that the entire system needed to be replaced. Being skeptical and knowing that such a replacement would be cost prohibitive, I was able to find found someone who specialized in boilers and works at Prompt Heating... He checked out the boiler, the thermostat and the registers and in one visit was able to diagnosis the problem.
Boilers are also called hydronic systems because they use water instead of air to distribute heat in your home. Some hydronic systems circulate the hot water through pipes and radiators, others use radiant floor heating (circulating the hot water through tubing in your floors).
We have years of experience fixing boilers in and around Milwaukee and can help you with problems like:
- Your boiler keeps turning off
- You hear banging, whistling or gurgling sounds
- Radiators are hot at the bottom but cold on top
- Pilot light is out
- Boiler is dripping, leaking, or losing pressure

Common boiler issues
Boilers are extremely durable and reliable. Yet even with regular boiler maintenance, equipment age and wear-and-tear will lead to problems eventually. The most frequent reasons for boiler repair include:
Kettling is the term used to refer to a boiler banging, bubbling, rumbling or making other troublesome noises. Kettling can be caused by a leak, overheating (usually from a faulty thermostat), or from buildup of limescale and other mineral deposits.
Milwaukee has hard water which means it has a lot of mineral content. Over time, minerals build up in the boiler which can change the pressure level, making a leak more likely. If you hear your boiler kittling, call for professional repair as soon as you notice it.
Leaks and drips
This is another warning sign you’ll want to call a professional for – especially if the leak is coming from the boiler tank itself, which could mean it’s corroded to the point of needing replacement. Leaks can also spring from pumps and pressure relief valves, which can be repaired.
Drips can indicate loose pipe or tube fittings, damaged seals, or a damaged valve. A lot of times drips are caused by wear and tear or a pressure issue. An occasional small drip from the pressure outlet pipe is normal, but check your pressure gauge anyway – if it’s in the red, call Prompt.
Pilot light problems
If your boiler’s pilot light won’t ignite or stay lit, you’re better off calling a professional rather than attempting to fix it yourself. Sometimes pilot lights just go out and relighting is straightforward – but when it’s a struggle or happens repeatedly it can indicate a serious problem.
Often the cause involves the thermocouple, a long wire that acts as a heat sensor. When it malfunctions the gas valve closes (as a safety feature) which means the pilot light goes out. Another common cause of pilot light trouble is the pilot tube that supplies gas to the pilot light. If it’s dirty and clogged the pilot light can’t get fuel.
Boiler turns on and off again
Also known as short cycling, there are many reasons why a boiler might fire up only to keep shutting off again. It can be caused by low water pressure, a broken pump, a faulty thermostat, issues with a heat exchanger, a closed or broken valve, or other issues.
If you’re experiencing any type of problem with your boiler, it’s better to be safe than sorry. Give us a call to speak to a technician, and if we can help you troubleshoot over the phone, we will. If we need to come take a look you’ll get a firm price quote for any and all work ahead of time.
Boiler repair FAQ
How much does it cost to fix a boiler?
There’s no way to quote a price without inspecting the boiler and diagnosing the problem. We understand price is a chief concern when you need boiler repair, and you’ll never get surprise costs with Prompt. We’ll add up the labor and any parts needed to fix your boiler, and give you a fair, firm price before getting to work.
Should I repair or replace my boiler?
It depends on a few different factors, the first being age. On average a residential boiler should last around 15-20 years. This can vary depending on how well and how often the boiler was serviced and maintained over the years. If you suspect your boiler might need replacing, the most important thing is safety. Get it inspected by a professional to make sure your older boiler model meets modern safety standards. If you’ve noticed your heating bills and boiler repair costs increasing year after year, that’s a sign you might be better off replacing your boiler with a more efficient unit. Give us a call and we’ll come take a look – if we can help you get more quality years out of your current boiler, we will!
Why is my boiler leaking water?
We’d have to take a look to tell you, but the first thing that comes to mind is imperfect installation. Corroded pipes, valves or tank can let water escape too. If mineral buildup leads to excessive pressure, water may leak from the valves (which is better than the tank rupturing). Seals around the boiler pump could also be worn and need replacement (in some cases the pump itself is damaged). And finally, as time passes boilers and other equipment can develop stress fractures, which can cause leaks to develop.
