He Was So Great
We just had a tech named Jon Mello here. He was so great: so knowledgeable, patient, friendly, and thorough, and best of all did a great job of balancing our system.

A Great Experience With the Team
We have worked with Coastal Mechanical in our recent new build, and it has been a great experience working with the team. From working with Rob initially to on-site visits by Bill and Brett, they have been so helpful and patient in explaining nuances of HVAC to us (we know little about these things!), never making us feel bad about asking questions. When we call, the office is also excellent—responsive and friendly. We highly recommend Coastal to anyone looking for a high-quality HVAC team!
