"The Smart Home features they installed, such as thermostat and door locks, etc. do not always work. For example, the Honeywell thermostat can no longer be operated from our phones and is difficult to install. Remote door locks are also unpredictable."

"The office was able to schedule an appointment to fit my schedule and the plumber, Tony, arrived promptly. He diagnosed the problem with a rusted pipe joint and gave me best-case and worse-case estimates. He was very thorough and persistent and replaced the bad pipes."

"Overall, I was very pleased with the results of this project. The crew was excellent and hardworking. I can't comment on the price because I didn't get another estimate. However, I felt that the price was fair for the amount of work that was done. I expect to be using this company regularly in the future."

"I contacted Donovan & Jorgenson to have them check out the boiler on our hydronic heating system. This was a flat-rate fall ‘tune up,’ and I didn’t have very high expectations. Two techs spent most of the morning tearing into the boiler, cleaning and testing, reassembling it and testing further. They worked methodically and meticulously. They completely contained and vacuumed any mess as they brushed out the burners and the heat exchanger. They were cordial, they answered all my questions, and they never stopped working until the job was done. Ours is a fairly ‘messy’ system, with four zones, five pumps, a heat exchanger that’s bigger than the hot water heater, and a few other curiosities. The techs seemed to be familiar with all elements of the system. We’ve been in this home a relatively short time. The previous owner recommended Donovan & Jorgenson to us, and now we recommend them to you. "

"Complaint filed 5/7/25 with BBB of Wisconsin. This is a HORRIBLE company who just blow off customer complaints who have legitimate concerns on plants that are ordered online and do not survive the year. They cover up reviews left on their site and on Facebook! My reviews were quickly deleted and none were posted to their online site! This company has had problems dating back to 1972 in a court case that’s public knowledge!"
