I would not only not recommend Coastal Cooling as an option or as a trustworthy company, I would advise clients to steer far away as their inability to correctly install and dishonesty in our situation should be seen a red flag for anyone. In 2022, we hired Coastal Cooling to install a new AC. It wasn’t working right so after 7 days we asked if they could come back to check on it. They sent out a technician and it took 2.5 hours to correct mistakes after the initial install, which included a leaking main unit and a missing pipe for white vinegar. Then, on Dec 16th of 2024, the thermostat panel in the living room showed black and was not working. We phoned Lennox as we thought the warranty had already expired and were told by them it was still under warranty, so we phoned Coastal Cooling, the company who installed the AC, and they sent someone over to see what the problem was. The technician they sent disconnected the thermostat, opened the AC unit, and to the best of our knowledge checked everything. After 30 minutes he told us the thermostat was broken, but was still under warranty, therefore making the replacement free. To have the Costal Cooling technician there for maybe an hour cost $149. The next day Coastal Cooling called and said they had new thermostat, which we were informed would be free because we were still under warranty, but they were going to charge $225 for the installation cost. As all the wires were still connected, and all that was needed was a new thermostat, which as they said would be free, and their technician would only have to replace the panel and check if it all was working would cost that much, we refused service. We went back and phoned Lennox who agreed it was indeed very expensive, but told us it out of their hands. We ended up purchasing a new Honeywell thermostat panel via Amazon and tried to install it but ended up calling the Honeywell help center twice, who were unfortunately unable to assist. So we reached out to another AC company who came to the house and checked the entire system for us. We were informed by them that the problem was in the AC unit itself, and the thermostat was NOT broken. Thankfully, they were able to fix all the mistakes Coastal Cooling had made and overlooked during their initial and recent visit. This company may come across as reputable, but based on their actions on the phone as well as the multiple installation problems, I would not trust them to accurately do their job and they are not welcome to step foot in my home again. It should also be noted that I did leave a review on their website, which was removed by them the day after it was posted, hence you will see this review in other places, not their site.
