We recently had one of our heating zones quit on us. We called Airtime (using Yelp) and the owner of the company picked up. He told me he'd assign a technician and text me with the appointment information. Within minutes he texted me that the tech (who turned out to be their service manager) would arrive at 10 to noon. He actually showed up at that time. Within minutes he had diagnosed the issue (bad igniter) and very soon had the issue fixed. No up charge attempts or phony issues.
These folks are honest and competent. Definitely a home run.
