Ryan from Superior HVAC Service performed a full duct cleaning and balanced airflow through each vent. The house feels evenly heated for the first time this winter.

Had an issue with my furnace not heating well, so I called Superior HVAC Service. Cole was the technician they sent, and he did a great job. He found the problem fast, got it fixed, and even made sure my water heater was running efficiently before he left. Super professional and friendly!
