"Scheduling was easy and they were on time for our appointment. Price for replacing our water heater was as quoted and very reasonable compared to other local plumbing services that quoted the same job. The water heater is a name brand with a warranty. All in all, Miley Plumbing was respectful of our time, our home, and provided quality service at a reasonable price. Plus, they are just good honest people."

"Outstanding company of real professionals. Work performed: 1. All power receptacles and switches were upgraded (new parts replaced old, wornout parts). 2. Assembled and install two (2) new customer supplied ceiling fans . 3. Provided and installed new 15A convenience 0utlet. 4. Provided and installed single pole 15A/20A arc fault breaker I have an eye for detail. Minor discrepancies leap out to me as well as minor work done well. Perhaps, twenty-two years in the military created this effect upon me. Sometimes it's a blessing and sometimes a curse as I find myself unable to accept minor, shoddy work. Example: All of the screws to the new face plates for receptacles and switches were oriented with the screwdriver slots in the vertical position. This was not done by chance by the team's three electricians but by their attention to detail and uniformity. If the small things are done perfectly, I feel it is safe to assume that all of the larger work is too. I have four more electrical projects to be accomplished and TE Certified Electricians will be my "go-to" company for these activities. I highly recommend TE Certified Electricians for your electrical projects."

"I cannot say enough good things about Mitchell and Demarcus. They called when they were on the way, arrived on time, and completed the installation in just a few hours. It was a tough job. The water heater was partially blocked by the furnace but Mitchell figured out how to remove the old heater without having to remove part of a wall, which is what I expected would have to happen. He re-piped the connections (the old piping was a mess!) ran the gas line extension to my stove area and placed the new heater. I had hot water within a few hours of job completion. I now look forward to hiring Mitchell again to install my new gas stove (once I buy it). I highly recommend Cool Air. I will receive a 10% discount on the water heater in the form of a gift card because I'm a Costco member."
