I had my water heater’s gas valve replaced, and the experience was great! Ian was skilled, efficient, and got the job done quickly. Everything is working perfectly now, and the service was both reliable and reasonably priced. I would definitely recommend them for any water heater repairs!

This is undoubtedly one of the best companies I have ever hired. Several companies offered me furnace installation, but Superior HVAC Service instilled confidence even over the phone. I am confident that my furnace will serve me for many years thanks to a safe installation from professionals with certificates and awards.

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!
