What customers said about a/c system repair
Precision Plumbing, Heating, Cool…Good service. Figured out what was wrong and it’s been working great. Just a little expensive.
Precision Plumbing, Heating, Cool…The technician was professional and knew what to check first thus discovering our AC problem(s) in a timely manner.
Precision Plumbing, Heating, Cool…Joe and Jeremy did a great job on troubleshooting my AC unit and would not give up until they figured it out. The unit is back up and running, especially during the hottest week we have had. Thank you for such great service.
Precision Plumbing, Heating, Cool…My AC went out on a Friday night so I called early Saturday morning for emergency AC service as temps were expected to reach 100 degrees. The technician, Kyle, was able to come right away and was very kind, professional, and thorough in explaining what he was doing and what it would cost. Im incredibly thankful the process was so quick and easy.
