Tech came yesterday afternoon and the crew was here today at 8 am to install a new furnace. It’s in an inconvenient closet, but they were done in 2 hours. Would recommend.
Allison Campbell
Great customer service. This company went above and beyond to help get the warranty part and got us running again. Courteous and helpful repairmen. Will definitely be calling on them again for future needs.
Megan Webb
We loved meeting CJ today and getting his professional assessment of our heater. We are very happy with the quick sameday service today. We look forward to a new heater installed soon. Thank you!

Coastal Heating and Cooling is the best! Whether you need a service maintenance or a full system replacement, the Team at Coastal will provide you with fair pricing and professional service. Jarrad and Andrew installed a full system AC and heating system in my home and I couldn't be happier. They were on time and worked efficiently. Once the installation was complete, both men explained the work they performed and answered all of my questions. Great job!
