I noticed our energy bills were climbing, and the furnace wasnβt 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 serviceβprofessional, knowledgeable, and thorough!

Conner replaced our heat pump, and from start to finish, he made the process stress-free. He was on time, super polite, and even made sure to clean up after himself (which I really appreciated). Our new system works perfectly, and Iβm already noticing the difference. Thanks again, Conner!
