Major Refit




Review of Holy City Heating & Air, LLC

The crew started early and were here all day. They never stopped working except for a 5-minute break. During the break they were strategizing what they needed to accomplish next! Entire crew was courteous, friendly, efficient, and knowledgable. Tom Harvey, the CEO, came by at the end of the day to check everything out himself. He found a problem with one of the sensors, explained the problem and came back the following morning to replace it and show us how the new thermostats worked. Excellent workmanship on the install and excellent service throughout.

Review of Holy City Heating & Air, LLC

A friend recommended that I call Tom at Holy City H&A when he found out I was looking to replace my AC. This goes to show that word of mouth is the best advertising. The entire process was easy, from the friendly quote process to the installation. The price was easily the most competitive I'd found, the installers were courteous and professional, and the end result is fantastic. This was a particularly tricky install, as it required a crane to lift the unit onto the roof of my building, but even with that added step, the whole process only took a few hours and when they left I would never even have known they were here, except for the cool breeze now blowing from my AC vent! I would use them again in the future and hopefully I can be the "friend" who passes on the word next time.
