I HIGHLY recommend Jason May and MayDay

Jason May with Mayday Heating and Cooling did a great job on replacing my HVAC unit for my basement and also for a serious, emergency situation regarding my upstairs ac unit. He responded quickly And worked diligently in oppressive heat in my attic to fix my AC as well as leaks dripping down through the ceiling into the hallway. He was courteous and never complained and his price was incredibly competitive!
