We have been waiting for a while to receive our Trane. It's here, installed and working fantastic! We are SO happy with the 2 installers. They were so very polite and knowledgeable. The Trane unit is what we replaced, and even though it took a little while. We have to replace our other unit, and we can't wait. Thank you, Coastal Air!

Positive:Quality,Responsiveness
We have used Coastal Air Technologies for many years. They provide outstanding service and are extremely responsive. Recently our compressor fan went out. They ordered a new fan immediately and also offered a number of alternatives to this issue. They replaced the fan and allowed us to beat the heat once again.

It is my experience that Coastal Air seems to be a local business who hires and trains local men and women to work in the most professional and kindest way. I have my heating and air units serviced every spring and fall and have never been disappointed with the service. I highly recommend Coastal Air Technologies for any of your heating and air needs.
