"Called Eric, he called back within a couple of hours. Came over to my house that evening with a new hot water heater per my requested specs.. Got it installed in about 2 hours. He also rerouted my gas pipes to the new hot water heater to meet code. He also explained what he was doing and answered all my questions. I will call Gans Plumbing for any future plumbing needs."

Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"In todays fast paced world, it is hard to find people we can trust and to wonder when we purchase something ,whether or not we are going to get a quality product for what we are paying for. I had been looking around to purchase some new windows for several years, but when I always heard quotes on the cost I was unwilling to take the leap. One day, upon hearing a quote of what the windows I wanted replaced would cost me from their sales rep., I took that leap. It was a no brainer. With such a great price, now I wondered if i was going to get quality for what I was paying. I have to tell you I was delighted to see the final results of my beautiful new windows. Not only were all the people I spoke with in this company kind and respectful, but they also helped me set up financing as well. Great Company, Really Good People, Quality Product and Service!"

"Jill H. St. Francis, WI 02 9/25/2022 First to Review It started out back in Jan 2022.. He seemed nice and polite but it just went downhill. He started way later than he thought and he showed up very seldomly.. very little got done after the kitchen had barely been gutted at ALL..after first few couple months to start.... After that, he had a family emergency..I was very understanding of that and I waited and waited and waited.. I told him I would understand if he needed to end the contract but he said no, he would finish it.. numerous times.. Everything got delayed for months and he would over and over say he would be there and wouldn't be. Mary Jo( owner) would call him but she would say she couldn't do anything.....nothing really changed.I had to constantly move stuff and back out of the kitchen thinking He would arrive.. almost never did..After I ended the contract, I had other contractors come in and look and they said it looked like an amature home owner did it.. gaps, cheap material , uneven, not 90 degree angels, etc.. and it would cost me more than I paid him ( which was a lot) to re- gut it and re do everything to make nice.. I'm sorry about his family problems. but it was NOT handled professionally- I was not a priority it felt from the beginning and even less and less as time went on as he wasn't getting paid anymore since he was way outside the time line of the contract... Cheap materials, and he admitted even he had to focus on his family (so I was basically just a crap job).. Updated as of 9/26/2022 The original project was to be a total remodel of the one kitchen area( not the bathroom area in the beginning) It was to be cabinet installation, new floors, soffits out, headers, shoeing, framing around windows, etc.. When I saw how crazy the ceiling looked and uneven and not straight etc with gaps , I was very surprised and I thought- why is he just patching everything in a very uneven sloppy way and didn't he just put in a new ceiling?? So I mentioned it..He told me it wouldn't be a big deal..at least what he said, . Mark and I talked about the idea of the bigger kitchen idea to make it bigger way back in the Jan/ Feb- ish time frame but I decided to think about it for a little bit first.... .. he said' Well you can always do that as a later project" I did end up deciding to do it about a month later then since he was already doing the work. If he couldn't do it, he should have just said so.. That being said, I'm sure I'm not the first customer to ask to add things on after the start. Again, the family emergency was very sad and I'm nothing but sympathetic, but it wasn't handled in a professional manner. He should have just been upfront that he couldn't do it instead of dragging me along for months and months and months..very unprofessional and not nice... ... He also left 3 foot wide holes in the kitchen floor that someone could have fallen into the basement, huge not safe messes all the time so I couldn't even get through even though he said it was usable.. He was very nice but almost never showed up from the beginning when he said he would.. not professional.. I always was very supportive of his family issues and again, asked several times if he wanted to end the contract , he said no.. I had other contractors look at the current situation and say that they had never seen anything like it and they would have to totally re gut it to start over and make it correct..... wrong kind of pine for inside, not straight angles, gaps behind boards etc-Again, I'm very sorry for the family issues but it is a job and either he should have ended the contract much earlier or just gotten it done properly and done a proper job!- I always wished him the best.."

Install Boiler questions, answered by experts

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
