- CRChuck Rantzow3 days ago5.0My AC stopped working on Wed, 1 just 26. Donovan S came over to trouble shoot the problem and verified the motor was bad. He came back on 3 July 26 to replace motor. Donovan was very fast and professional in changing out the motors. Very courteous and knowledgeable young man.
- JSJudy Schaefer4 days ago5.0Jake was very informative and helpful to remedy the water problem. My concern is that this was leaking again this afternoon, because Dave was working in the basement until noon and said it was almost dried out from yesterday. I rate Jake’s job a 5 especially for his professional job. We will allow it to dry out, call back with any concerns. Judy Schaefer
- CKCindy Koelsch5 days ago5.0Jon was great , he explained what was wrong with my AC and got me setup to talk to someone for a replacement. Wish it would have been an easy fix instead of replacing the AC. Thank you Jon! I didn't see any pictures u took.
- WSWilliam StoutJun 26, 20265.0Kyle was helpful. Kyle explained how the water heater worked. While he was helpful, I should have been told how it worked when the unit was installed (only a few monthsago). This "service" shouldn't have been needed. With this in mind, the service was overpriced.
- JKJoan KutzJun 19, 20265.0We had 2 mini-split units installed in our tri-level home. Ben G., and his team of Keegan and Logan and the Electrician MJ, did an awesome job and they were very professional. Ben was very polite and he explained how to use the mini-splits and the remotes to operate them. He answered all our questions thoroughly. We are very happy with their service and would highly recommend this team of hard workers. Thank you so much! Dennis and Joan
