We are extremely happy with Comfort Control and especially VuTran who was a thorough and knowledgeable professional. We called a few technicians who could not figure out our HVAC problem as everything was working yet there was no air flow in the apartment. Vu Tran is such a seasoned expert that he was not only able to identify the problem but fix it. We are so happy with his service and expertise. Thank you Comfort Contral and Vu Tran!!
