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!

We've had issues with our tankless water heater struggling to keep up with demand. The repair person named Reard tried a few things, and our system is working like new again. Highly recommend Superior HVAC and services.

While I’m giving Superior and Daneil five stars, the other man that was with him was less than 5 stars.I unfortunately had to go out of town and had my elderly parents home to let them in.A bed and ceiling panels had to be removed and moved to do some of the work.The man told my father moving things and getting on a ladder to remove the ceiling panels weren’t his job.My father is 77 years old and was made to climb the ladder.I’d be curious to know if someone was in a wheelchair and couldn’t physically move furniture and climb a ladder would it still not be his job? Other than that, they were able to fit us in quickly, and got the job done safely and efficiently
