Sam was our technician, we feel like our furnace & humidifier checkup got their best care. Thank you, Sam! Today we paid for this checkup & for our 2026 A/C checkup. Thankfully, the 2 system checkups price had not increased from the previous year.
Response from the owner:Thanks, Olivia! We’re glad Sam took great care of your furnace and humidifier during the checkup. We appreciate you trusting us again for your 2026 A/C service!

They came to look at our sump pumps to make sure they were working properly. They were working properly but it gave us peace of mind to get them checked out.
Response from the owner:Thanks, John! We’re glad we could help with your water heater replacement and appreciate your trust in our team.

The fix for this old house’s main toilet is constrained by very ancient building practices. CU has had to create a work around to prevent an expensive permanent repair. I am extremely pleased with the newest approach brought to bear on the problem.
Response from the owner:Hi Fred! We are so glad you are pleased with our work. Thanks for the review !
