My boiler started making strange noises, so I contacted Superior HVAC Service. Farid arrived on time, diagnosed the issue right away, and had it repaired quickly. He even checked my furnace to ensure everything else was working properly. Excellent service from a knowledgeable technician!

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!
