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!

Couldn't get to the "19 more choices" of services to check off install of smart/wi-fii thermostat. ALLEN did a fabulous job replacing the thermostat with smart/ wi-fii capable one. Took care of a minor issue from the furnace install in January and signed us up for a maintenance plan on HVAC. He was knowledgeable, and patient working with us on workings of this new thermostat.

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.!

Excellent Techs!! We had two out here on the same day, Jordan for the furnace and Terry for the plumbing, and they were both great. 5* for both! The thought that went through my mind was, "Where do they get these guys?" ... meaning that they were both great, as was the tech that checked our system last year. Whoever does the hiring does a good job. Thanks!

Jordan was very professional and explained everything he was doing with the maintenance and yearly checkup with our furnace and completion of updates to the system . Would like to have him doing our yearly annual maintenance with furnace and air conditioning unit.

Except for having to purchase a new furnace, the technician was professional and courteous. Jordan explained everything on my 20 year old furnace and gave me many options to choose from. Excellent people to work with!
