From the representative that provided the quote, the office personnel that answered my many inquiries and questions, to the technicians that did the install, the experience was flawless. I was encouraged to get several quotes and Donovan & Jorgenson's estimate was in the ballpark of all the others; actually offering above standard units compared to others. Would highly recommend them to anyone looking for top notch service and expertise.

I contacted Donovan & Jorgenson to have them check out the boiler on our hydronic heating system…read more 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, and 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.

They are not hiding costs, burying money places or charging "extras". In this business you get what you pay for - and I have not ever been happier with HVAC service and repair ever.

Uttke performed a diagnostic and confirmed what I thought all along--the air handler was not cracked, and there was no carbon monoxide leaking into my home. The system was cutting off because I had installed one of those "smart" thermostats that have given homeowners so much trouble. Uttke did show me a good replacement for my furnace when the time came--a mid-range Armstrong furnace. I appreciated their integrity. I went out of my way to purchase AprilAire filters from Uttke because I appreciated how I was treated. Fast forward a couple years and I had moved to Cedarburg and needed two heat pumps. I called Uttke, got an in-person assessment, and a quote. I purchased on the spot and within days I had two heat pumps installed. Uttke was great in terms of communication to make certain the units were placed where I wanted them, and where they would make the most sense. I would recommend Uttke with confidence.
