Ryan from Superior HVAC Service diagnosed a bad ignition module on our furnace. He replaced it quickly and stayed until the flame sensor tested perfect. The whole experience was easy and professional.

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 I’m already noticing the difference. Thanks again, Conner!
