Daniel showed up exactly on time. Same day within two hours of the initial call. He and his team were polite, professional and made every effort needed to complete the job in a timely manner. These folks worked well past midnight and replaced a broken AC beyond my satisfaction in less than 6 hours. I highly recommend Daniel and the team at Superior HVAC services.

Called Superior HVAC Services as I was having issues with hot water in my house. They sent a technician named Ian the same day. He did a thorough inspection, checked all of the fixtures in my house. Turned out my water heater was working and the mixing valve failed. He explained what caused it and how to prevent it in the future. Very knowledgeable staff and helpful. Gave a quote for services needed. I am satisfied with the service and with the technician. I hope all services are like this! Happy client here!
