Our gas fireplace wouldn't light. Superior HVAC Service sent Maria, who quickly cleaned the pilot light and got it working again. She was friendly, efficient, and charged a very reasonable fee. Highly recommend!

Our furnace suddenly stopped blowing warm air, and we were freezing! Conner quickly diagnosed the issue as a bad blower motor and had it replaced the same day. He explained everything in simple terms and even checked the rest of the system to make sure we wouldn’t have more problems. Super professional and friendly—highly recommend!

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!
