Last week I needed an air conditioner repaired and I was lucky to bump into Superior HVAC Service. They are honest, hardworking guys. The prices were reasonable, and they were very responsible about leaving my house as clean as they found it. You will not be disappointed!

The two technicians were very friendly, informative and professional as they diligently installed our new AC unit. They left a very clean workspace and tested the unit before leaving. Very happy with this service!
