Best HVAC System Maintenance in Milwaukee WI

Very responsive. Good followup. Highly recommend

Very satisfied with work

I had a very helpful conversation that lasted about 25 minutes when I called to book an appointment. Ultimately, I didn’t make an appointment because it wasn’t needed, and OW was honest and helpful in explaining WHY it wasn’t necessary. What integrity!!

They sent a gentleman by the name of Scott. He's simply amazing. I'd give him a 10+ thank you Heiden plumbing.

Terrible , they took apart my furnace and left with parts. Scam .

Journeymen that work there are great, but Brennan sends you a lump sum bill and won't respond to any questions regarding it. I have tried for over 4 months to pay a bill, but I get a different answer every time I ask. I sent a letter to one of the owners, again trying to resolve the $500 plus bill, but never got a response. Horrible customer service. It's too bad as the journeymen that come out for service have always been great. Other tenants in our building downtown also complain about they feel they have been overcharged many times. We have a great HVAC contractor in Brookfield that we'll have to use in the future.

John (master plumber) was recommended by a friend of mine and he came out to look at the work needing to be done giving free advice. However even after hours of confirming he would be out here to do the work he never showed up. He never called back or returned any of the messages that were left. I waited all day for Friday and am now without any running water in my house for the weekend and gosh knows when until I can find another plumber to come out and fix my busted water pipe. I thought I could really trust this person and had he even called to tell me something came up or any reason he couldn’t do the job would have been acceptable but I heard nothing back! This company unfortunately can not be trusted to show up to do the work needed to fix any problems.

Tom was professional, informative, and pleasant. He helped us with our backup in the basement, and gave us options. Thank you

Words cannot describe the professionalism, attention to details, and responsiveness IcyHot founder Hector gave to us! We were referred to him by a friend as the big box HVAC companies were unresponsive to our lack of heat. Hector answered us immediately, came out to our house within an hour for a quote for a new boiler, and installed the next day!!! He would not leave our house on day of install until we had fully function heat. Words cannot describe the amount of faith and hope we put into Hector and his crew to come to our rescue as our home was without heat and 55 degrees (of note the big box company had over a week and did not even provide us with an install date....so yes! we were without any head for over a week until Hector came to us!). The next day he and his crew installed our new boiler, ensured everything was fully functional prior to leaving, even went above and beyond to clean out our 1906 pipes/plumbing which is above and beyond the quote (and didn't charge us extra!!!!). This is the first time in 15 years of using a big box company that we actually have equal heat on our second story which mirrors our first story! Again....words on this review cannot describe our extreme joy and warmth with Hector's professionalism, responsiveness, and HVAC expertise on what our unique 1906 plumbing needed to guarantee us heat and peace of mind. Highly, highly recommend to all!!!!!

Got the drain unclogged but left a mess in basement which I had to clean up. Don't know if this is standard operating procedure
