Best Heating And Cooling Repairs in Milwaukee WI

Had 2 tankless water heaters installed approximately in 2021. Pressure relief valve failed on one of them. Valve was under warranty. Phoned and emailed repeatedly. Finally after 2 plus weeks they got back to us. The problem was resolved. Now the relief valve on the other is failing. Emailed them on January 2nd and received no reply to this date. Please contact me so I can get this situation resolved. Installation of water heaters were done professionally and I was very satisfied. But getting in contact with company could use some improvement.

Want to commend Jack Hanley; did my replacement on a hot water heater.
Most professional: and best service that I've received in a long time.
Would highly recommend Hartlaub and this plumber!

Omer installed a tankless water heater for us. He explained every step of the installation and was extremely helpful/timely with the install. We are very grateful for his help

Wonderful experience, honest helpful people. I had a water pressure issue with my shower. They were able to come out the same day and quickly identified the problem and made the necessary repairs. I would recommend them to anyone who needs a plumber.

I had my furnace inspected by Kurt B. He was very prompt and professional. Highly recommend. I will use them again.

Always on time and efficient.

The best of the 'hardware' stores. I like being able to look up items I need online and seeing where they are located in the store ahead of time, which saves a lot of time. Service is great, and employees are knowledgeable. Only wish they would still cut plywood and plexiglass to size like they did in the past. Must be some liability thing now. Otherewise, an all-around awesome experience for any home needs.

I love they free learn workshops.....
