Installed a new furnace and AC today. Dean and Nick did an excellent job, worked quickly and kept us informed about the progress, and were a pleasure to work with. Took great care to keep floors protected and cleaned up beautifully. Price was a bit more then we hoped, but with the great warranty and excellent financing we felt we couldn't go wrong. They Installed our last system 31 years ago. Always pleased with this company.

Darrius was courteous and helpful. He solved our issue and recommended a service plan that will help maintain our furnace/ac units affordably. My wife felt very comfortable with him and wants him back to maintain our furnace/ac…and she said thank you good sir!

We called CCS about a month or so ago to complete a furnace check-up and to inquire about an annual maintenance plan. Jordan, our tech, completed the total job in very close to 1/2 hour. Then we signed on for the plan for Spring/Winter maintenance. Everything was top notch! I can’t say enough good things about Aquarius/CCS! If you’re looking for any heating or water service to be done, I highly recommend Comfort Control Systems…job well done! Thanks Jordan M.!
