Great service

Very informative as to my system. Helped me to understand the cost effective and comfort levels of my entire heating and air exchange components. Very much appreciated.

Exemplary Service

We had limited hot water and a family member recovering from surgery, even though their schedule was booked well in advance Johnson Bros. arranged to come after hours to install a new water heater. Forever grateful to them!

did a great job and kept me informed as to what he found along the cleaning process.

I found Kurt to be totally knowledgeable of what he was doing and explained what he found. He gave us some options and good advise. He was not pushy on what option we should take.

Excellent !

I am a very satisfied customer. My heating cooling system was evaluated and synched today by an employee of Johnson Bro. I appreciate his technical expertise and helpful professional manner.

Kurt was great!

I had a broken sump pump and dead battery in the backup, and 3” of water in the basement, getting deeper. I woke Kurt up at about 3am and he was cheerful, knowledgeable, and helpful for the next 3 hours. He got a new pump installed, waited until the basement had drained to be sure it stopped when it was supposed to, tested the battery backup and verified it needed to be replaced, and answered all my questions. Thank you, Kurt!

Super service!

I bought a new pressure tank. They were prompt, friendly, and honest. They went over and above by cleaning years of crud out the pump area I could never get at before, and put new brass fittings on the joining pump hose that I didn’t know needed replacement. AND when they discovered that the first tank they brought out had been slightly used, they promptly returned it to the shop and brought out a new one. I never would have known the difference. I’m very happy with their work! Good experience.
