Dolphin has been our go-to A/C service at both of my businesses plus my house for several years. They replaced an a/c unit and fixed another unit that was installed by a very shoddy company. They have a maintenance agreement that is for two times a year maintenance that I really like because I can’t keep track of when service was done on everything! We are pleased with their installers, service technicians and office support staff and would recommend them if you are looking for a quality a/c company.
