I contacted Superior HVAC Service, Heating & Air Conditioning after noticing my furnace was making unusual noises and not heating evenly. The technician arrived on schedule, identified the issue quickly, and explained the repair in a way that was easy to understand. The problem was resolved efficiently, and the furnace has been running quietly and consistently since. Very professional service overall.
