I have worked with many different HVAC-R companies trying to get my ventilation equipment working properly. Finally I found CIS. One service call and it work and still works perfectly. Thank you CIS!
CIS’ staff handled all of the HVAC-R equipment installation in my newest construction project and is setup to handle the next couple facilities as well.
Thank you CIS for being there for me when I needed you most. My boiler is finally running well and more important continuously. Great job to their staff. I should have call you last year.
I really enjoy working with CIS’ team. They are truly concerned that my facilities HVAC-R equipment is running optimally. Even after a repair, CIS’ staff calls me to make sure that everything is working correctly. They care unlike other companies that we have dealt with over many many years in business. I always suggest CIS whenever a friend or client asks for a great HVAC-R company.
