These guys really know their stuff! Our furnace went down earlier in the week and our house was freezing! George was able to come and asses right away, and provided solutions that worked well for our family and budget. I highly recommend Superior Heating and Air Conditioning!

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!
