Too bad all companies don't have such outstanding customer service. Company is lucky to have those two employees.

Very professional and fast.
Very professional and fast. My Nest thermostat gave me an alert that there was no AC in my condo. Tech Cameron was on site within the hour. Unfortunately, my issue is most likely due to our rooftop deck being redone. Still, very nice. Advised that I call the building’s manager to alert them ASAP.

Best company by far!
Air conditioner broke down at the worst time... middle of August during a heatwave. 🥵 Contacted 3 different places to see if I could get someone out here. Intelligent Service Heating and Cooling was the best company by far! Was able to get an appointment for the following day and a technician named Trevor was excellent. Very professional and extremely kind. Two minutes after meeting him I felt like I was talking to a close friend. And the young lady who is responsible for sending confirmation text messages and arranging everything was great. I think her name is either Rachel or Robin? She and Trevor represented the company very professionally, which I definitely appreciate. Too bad all companies don't have such outstanding customer service. Company is lucky to have those two employees. Alex
