"Precision installed my water heater two years ago. When I had my furnace serviced, the technician checked the pressure on the water heater and it was very high, a component had failed. A plumber from Precision came out and replaced the defective part since it was under warranty. He suspected that a water pressure regulator may have to be installed but when he checked the water pressure coming into the house, it was in the acceptable range. He could have just as easily told me I needed this and it would have cost me $600 but Jacob was an honest man. I am so impressed with his integrity. I will use them again in the future for sure. The replacement of the defective part didn't cost me anything. Thank you Precision for being an honest company."

"It was great to find a HVAC guy that really knows his stuff. Devin showed up on time and was able to troubleshoot a boiler he had never worked on before and make the necessary repairs within a few hours. I will be using Coal Creek in the future."

"I bought a dishwasher at Home Depot to be installed, They came out  and said they couldn't do it because I didn't have a shut off valve and one needed to be installed be for they could do the job.  I called ProServe told them what I needed. Tech came out, said I didn't need a shut off valve, the one in the laundry would be fine. He then installed the Dishwasher within 45 minutes.  I will definitely be using ProServe for any upcoming plumbing problems.   Fast, Fair, Excellent Service,

"The materials arrived about 15 minutes ahead of the crew and were staged for efficient use outdoors and for bringing into the house.  Four guys arrived as scheduled and immediately all went to work - a flurry of activity.  The guys inside laid down plastic and had covers on their shoes so that no dirt was tracked.
I had been told that the installation would take a full day - and they were true to their word.  Things were explained as they went so I knew how to use the thermostat, change the furnace filter, etc.  They were all very professional and courteous, and when they left I couldn't tell they'd been there.  Not only was the service outstanding, but the products are even better!  My utility bills are proof as is the extremely quiet air conditioner running outside.  I couldn't be happier with the service or results.
