I used Coastal Service Of Delmarva to repair my air conditioning. The office staff was very helpful and they were able to send someone to my house within an hour of my call. The tech was very knowledgeable and explained the problem before he began the repair. Our air conditioning was up and running again within about an hour of his arrival. We`ve been cool and comfortable ever since. I would definitely use Coastal Service Of Delmarva again and highly recommend this company.
