Customer Reviews

Clayton Derby

We have been using City Air Mechanical for our HVAC and plumbing needs for many years, and they have always been timely, professional, and friendly. Those are all attributes that we all expect in services but may not always received. Today, they went even further to the point that I was compelled to write this review. Our water heater started leaking this morning. After taking care of the initial water on the floor, I called City Air. In less than 2.5 hrs, the service team arrived, removed my old water heater, installed the new one, and were pulling out of the driveway! NOW THAT IS SERVICE! Thank you, City Air.
