Debbie Mast
I had a furnace issue in the early morning hours 1-26-26 I called the service number and within 5 minutes got a call back from Dan Elbon. He was at my house in 30 minutes. He got problem solved but said he needed to return later in the day to complete the job. Back at 2pm and I am grateful to know I am safe and warm. I have been working with CU for a year now and so glad I switched to them. I hope CU knows what a valuable and loyal Dan is!
Response from the owner:Thank you, Debbie! We’re so happy to hear that Daniel provided excellent service and made such a great impression. It means a lot that you’re choosing to switch to C-U for your future needs. We look forward to serving you and appreciate your trust in us!
Michelle Osman
Great service, reasonably priced! I needed to find a new plumber after my last contractor left me with multiple leaky repairs. C-U sent over their guys immediately. Right away they diagnosed what was wrong with the previous repair and had it fixed within the hour.
Response from the owner:Hi Michelle! We are glad you called us and that the plumbers found the problem and got it all fixed. We do electric and HVAC too so anytime you need home maintenance, give us a call! We really appreciate you taking time to give us feedback and we hope you stay warm this weekend!
Lori Smith
They were very friendly and informative. Gave us some suggestions as to what the problem was. We had a sewer odor in our house. Thought the outside drain needed cleaned out. They were honest about it. It did not need cleaned. They were recommended to me and I will 100% recommended them.
