I've been a customer of Rox air for a few years. Both for air and heating but also water heater. I am on there maintenance plan and they come out twice a year and do a thorough job checking out the systems. They spend a lot of time to make sure everything is working right for the next season. I would recommend them to anyone.

Rox Heating replaced my almost 30 year old HVAC with a new heat pump recently. The experience was extremely positive from the very beginning till the job got completed. Scheduling process was hustle free, techs arrived right on time and gave us a heads up call 30 minutes prior to their arrival. They kept us informed on the installation progress, which was great since we were had activities planned that day and had to adjust our schedule. ROX techs gave us a detailed walkthrough on how to use the new heat pump. We really appreciated follow up calls from ROX’s office to make sure that everything was done to our satisfaction. I would definitely recommend ROX Heating and Air to anyone who needs help with any type of HVAC work.
