I Highly recommend Mike and Brian from Mid State Heating and Air. They are highly knowledgable in all areas concerning HVAC. They replaced an upstairs air-conditioning unit, as well as outside heat pump. The air conditioner/heat pump brands were Carrier/Payne. They also discovered an unknown issue with our venting and were able to fix that as well. I was able to communicate any questions/concerns easily with them via cell and email. Scheduling an appointment was quick and easy and they were flexible to meet our needs. Pricing is very competitive.
