Justin #48 is a great service technician
Justin #48 is a great service technician and honest person. He was logical in his approach, thorough in his evaluations, and reasonable in his assessment of how best to proceed considering the current age of the AC equipment. I will always ask for Justin #48 for my future HVAC service needs.

Very happy with the experience!
I had been having intermittent issues with my AC unit and it finally stopped working. I called and someone was dispatched and arrived within an hour of scheduling. Brandon Freed was extremely nice and kept me informed of the problems as he worked. He was able to get my 25 year old system working again. I will need to replace the unit soon but for the time being he was able to get it working! Very happy with the experience!

Very polite and respectful
Very polite and respectful, great communication. The AC was making a clicking noise, which Chris checked out to be nothing related to the motor. Paid 89.00 for the service check. It turned out the clicking noise was the door vibrating when the unit was running.

Same-day weekend solution
Chris came out on a hot, 96-degree Sunday afternoon and performed persistent troubleshooting on my condo’s “First Co” air handler to eventually diagnose a loose connection near the switch. Nothing seemed awry until he did the examination with the power on. It was great to get a same-day, weekend solution and be back in business with cool air!
