Report
Coastal was fantastic. The technician Adam was great. He was professional, personable, and very knowledgeable. Adam made our first experience with Coastal one we we never forget. Adam not only took care of our HVAC issues but also took the time to explain your service agreement, to which we took advantage of before he left. Thank you Coastal for employing Adam, we will always recommend your company to anyone and everyone who needs HVAC or any other issues repaired. We will also be requesting Adam when the time comes to preform preventative service on our HVAC. Thank you Coastal and thank you Adam.

Report
Jeff, from Coastal A/C came to do my Spring A/C tuneup. I explained a concern I had regarding my heat pump over the Winter. He checked that concern out for me as well as performing the tuneup. He explained the increased electrical usage to me in terms I could understand. I agreed it needed to be dealt with and he gave me the cost of the part in minutes. Additionally, I had questions about an alternative heat source. He answered all of my questions and gave me his opinion. He is knowledgeable and thorough. I trust Coastal and will deal with them for years to come.
