Steve Shannon
“Brian was polite and very good at this job. He patiently taught me how to better care for my air conditioner, and explored all possible solutions to my problems. I will request Brian in the future.”  
Karen Musemic
“I was once again very pleased with all of the above areas. I feel confident that the representatives have my best interest in mind.”
Louise Harrison
We thought the Hoffman team did an exceptional job on our most recent installation. The drilling crew working for Keeven: Tony, Danny, and the rest of the crew were a top notch group of hard working guys who did a great job. Once any problem was identified, we appreciated their earnest effort and extra hard work to resolve it all the way to the end.   
I think Highest marks have to go to your technician, Todd Ehmke. He was exceptional in his effort to get the system up and running. He took extra time to explain the work plans and details of any problems. He worked extra long hours to keep the work on schedule and resolve some glitches they encountered during installation. He is a true asset to your organization. When Todd finished his part and Tim took over, the work continued at a very high level until they were finished. As a technical person with a strong engineering and physical science background, I appreciated their willingness to explain the details of the system.
Ilene and I also appreciated the integrity of all members of the crew. Hoffmann brothers should feel proud and confident that they have a team of workers who are courteous, friendly, and trustworthy. 
As for the geothermal system: our house has never been cooler or more comfortable and our yard has never been quieter. It is nice to sit on our patio or by the koi pond and not have to talk over the noise of the cooling units. Besides being noisy our old conventional system could never quite cool the entire house on the hottest summer days. We could run all 5 zones continuously and still not cool some of the upstairs bedrooms to 84. Thankfully the new geothermal system was up and running when we had the hottest days of the summer. We now have the ability to cool the house to a comfortable level on the hottest days with plenty of room to spare. We even pushed the system to see how low the inside temperature could go but called off the experiment when we hit 72. It was just too cold. I will let you know how it works in the winter.  Hats off to Hoffmann Brothers.”

“My salesman Tim was very helpful in explaining the differences/expectations in Geothermal Heat Pumps and specifically my choice that was to be installed. Adam was very courteous and efficient with the installation. Thanks!”         
Mitchell Montgomery
“I was very impressed by how polite they were, and very nice. My 4 year old daughter got a big kick out of the shoe protectors they wore and I appreciated that they didn’t track dirt into my house.”     
Laura Deweese
“Service personnel arrived on time (early actually), were friendly, and courteous. They kept me informed throughout the installation process and its progress. They also cleaned up the work site very well. “
Marie Goedde
