Mike was excellent. He was courteous and professional, and after talking to me for five minutes, he knew what the problem was and was working on fixing it. He was upfront about what he was going and explained the costs before starting on the repairs. It took him less than an hour to have the boiler part replaced, the thermostat tested, and the whole system up and running. On top of being fast and professional, Mike was very courteous. Our five month old went down for a nap in the basement (where we had a backup heater) near where Mike was working, and he tiptoed and whispered so as not to disturb the baby. The price for the service was very reasonable, and my boiler was up and running less than three hours after I first called. I am likely going to continue to use Capital for all future heating needs, as this experience was great.

What made us choose Nimmer was a couple of things. One was the time Mark Nimmer spent explaining the best option for our house. He really went into detail why we didn't need the highest rated boiler given the type of hot water system we had. Second, they were the only company to offer a Buderus Boiler, which through researching, I found to have very high reliability ratings. The installation was done in a very professional and neat manner. Because we have a somewhat unusual radiant hot water system ( the pipes are in the ceiling) it took a few calls to get the air out of the system and adjustments to regulate the water temp. All the service calls were responded to quickly and professionally. Very pleased with Mark and his crew. This spring we had them out to look at the AC unit as it was not starting. Mark found a loose wire, then cleaned and checked the condensing unit. He found that it needed a new capacitator which he ordered and also recommended that we replace another part that would better seal it from insects and prevent power surges from possibly burning out the unit. All services were done in a professional and timely manner.

Businesses in high demand can react to high demand in two ways, good or bad. Aire Care, a local company in this area, has always been friendly and reliable. Unfortunately, it would take too much time to explain how awful they were when we called to ask for help with our boiler. From subtle...

All the repairs were done professionally. Although the leaky shower problem took most of the summer to resolve, the end product has been worth the trouble.

I've used this company at my income property for many years (15?). Most recently this past June and November. In June 2016, I had the boilers in the property cleaned/serviced. Then, early in November 2016, one of the boilers was not working properly. Knauer came out and fixed the problem and...

I thought the service I was getting was more than adequate, but I've had some other HVAC contractors out lately. They point out things that they would do differently. For example, we have an auto-vent on our hot water boiler. I was told that they would take out the auto-vent. It is easy...

Capital was fantastic. The boiler in my home stopped working, and the house had dropped to 55 degrees. My wife and I have a five month old, as so we were frantic to get someone here quickly to fix the boiler. After calling a few places that could not free anyone up, Capital answered and the...

"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager.

FAQs for boiler repair projects in Bayside, WI
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
