    We had Cliffs install our generator. From the beginning Paul was great on explaining the process and getting us scheduled in under a week. The install team of Ed, Darius, and Will were professional and friendly. Ed was fantastic answering all of our questions. We would recommend this service and team to anyone!

    Great experience with this company. It was time to replace both the furnace and air conditioning. Paul came out for an estimate and provided a good overview of my current system. Then provided information on how to improve the operation of system / increase performance and provided a competitive quote , I had received 4 estimates . The installation team arrived on time, were courteous and completed the installation of the furnace / air system same day. They also cleaned up all the work areas and provided instructions on operation of the new system.

    Timely response to initial inquiry regarding installation of generator. Cliff's was very cost effective and the duration from acceptance to installation was very short. The installation itself was very professional. The technicians were extremely competent and courteous with an excellent work ethic. I highly recommend Cliff's Professionals.

    We've trusted Cliff's with our heating and AC needs for several years, and they've consistently provided excellent service. When our 26-year-old AC unit started struggling to keep up, Hunter, Ed, Tom, and the rest of the team quickly assessed the situation and gave us several options. We ultimately chose to replace the unit and were originally scheduled for installation a few days later. However, after a cancellation opened up, they called us back the same day and completed the installation immediately. Tom even made a special trip to pick up the new unit to make the quick turnaround possible. From start to finish, the entire team was professional, responsive, and great to work with. We couldn't be happier and highly recommend Cliff's!

    Hunter was great. Diagnosed the problem and made the repair quickly on my mother in laws AC unit. Made sure the unit was working properly and did not leave until the the house dropped a few degrees. Would highly recommend Cliff's!

    We recently had Cliff’s replace our furnace and AC, and we had a great experience from start to finish. Their pricing was decent and our job was started a few days after our quote. The technicians were professional, quick, and worked efficiently the entire time. Everything was completed smoothly and the job was done great. We’re very happy with the results and would definitely recommend Cliff’s to anyone needing HVAC work done!
