Fast, professional, and precise installation for my air handler. They've explained everything clearly and cleaned up afterward. Thank you Ian, their tech guy. Couldn’t be happier with the results. Would absolutely hire them again! Keep up the good work Superior HVAC!

I noticed our energy bills were climbing, and the furnace wasn’t heating as efficiently as before. Kevin from Superior HVAC Service came out for an inspection and found that a clogged filter and dirty burners were reducing efficiency. He cleaned everything, replaced the filter, and fine-tuned the system to run more effectively. Not only is the house warmer now, but I can already tell the system is working less to maintain the temperature. Excellent service—professional, knowledgeable, and thorough!

Woke up to no hot water and immediately called Superior HVAC Service. Hunter arrived on time, quickly diagnosed the issue with my tankless water heater, and had it working again in no time. He even did a quick check on my furnace to make sure everything was running smoothly. I really appreciated his professionalism and attention to detail!

I recently had a new water heater installed by Superior HVAC, and Brian handled the entire installation process. He also inspected my boiler for any potential issues. I’m very satisfied with their new unit installation service and would use them again.
