Had Adam prepare a quote for us to do some plumbing work to replace our water heater. He was very professional and knowledgeable about the installation and answered all my questions. Would recommend this company.

My furnace died in the middle of winter. With the wife panicing I called Superior HVAC and the technician arrived to my house the same day. Told us our 16 year old furnace wasn't cutting it anymore. We decided to get a whole new furnace which was installed the very next day. They were very professional and left the area clean (Looked like no work was done after they left). I highly reccommend this company for furnace repairs
