What Customers Are Saying

Traffic was a nightmare to make it home in time to meet the technician. After calling the office to let him know I was running late, he waited on me. The customer service that was provided was excellent and the technician was very knowledgeable.

Gene Lewis of Sing Heating and Air is the BEST! He’s serviced our unit about 10 years ago. He’s honest, professional, very knowledgeable on what he does, pleasant conversationalist. All around good guy. I trust him, I trust Sing HVAC. He just gave our unit a clean bill of health and I’m happy. I’m hoping to get 10 more years from this unit before we have to replace it or make repairs.
