“A great experience! Their communication and service is excellent. They quickly responded to our request for an estimate to provide a central heating system to replace old electric baseboard heat. They were on time for every appointment and listened to exactly what we were trying to accomplish in our home. They also provided great options at the best prices. All work was done well and very neat ensuring that everything was clean before they left. If you are looking for someone to do your HVAC work, do yourself a favor, stop looking and call Coastal Air. I will use them for any future service and would recommend him to anyone. ”
