Best Radiant Heating in Milwaukee WI

The customer service was excellent starting from the kind person I set the appointment with through the technician the day of service. Pricing was clear and upfront. I would highly recommend Hartlaub. We're lucky to have them in New Berlin 😊

My family has used Knauer for a variety of services for over 50 years. We have always been very satisfied with their professionalism, helpful suggestions, and prompt service.

I had such a horrible experience with this company. Especially with their tech Jim. Who by the way is very unprofessional and rude. As soon as he saw my furnace he said, I'm not touching this. He did not know how to trace conduit for incoming power disconnect switch. Another tech had to come out and take a look at it. Joe was more professional and so knowledgeable, friendly, and answered all my questions. You can tell he knew what he was doing. Not like Jim who conducted poor service. I would not recommend this company at all. I even left a voicemail for the manager. Not a surprise she never called me back. Shows you how this company conducts their business. I DO NOT RECOMMEND.

I met Paul for the first time today. I thought I needed a new water heater since I had no hot water. Paul arrived on time, was courteous and professional! Once he was in my basement, he saw my pilot light was not lit. He lit it for me then took the time to show me how to light it should it go out again. I will definitely call him when it is time to replace my 10 year old heater! Thank you, Paul!

Dave was extremely knowledgeable, efficient and friendly. He noticed a secondary leak I didn't notice.
Also fixed my bathtub spout.
Excellent service!!

Had a couple of plumbing issues, and from the first phone call to the technician walking out the door, the overall experience was great. Everyone was very helpful and polite, and you didn't feel like you were being ripped off.

Just recently used Seider for the second time and couldn't be more happy with the redults.

My daughter needed her hot water heater replaced. He arrived promptly and started to replace it. Since it is an older house, there were other problems that became evident. He called my daughter to explain what else needed to be done, and came back the following week to complete the job. She is very satisfied with the result.
Everyone was so nice from the first phone call until the end. Very professional work. I would highly recommend.
Just a side note, they are located 45 minutes away and arrived promptly both times.
