testimonials

I just wanted to check up on the HVAC system services with you and couldn’t be happier with how everything turned out. Your company provided the most competitive quote and backed it up with superb service. The people that came out and installed spare parts of VRF/VRV air conditioner system were fantastic. They completed the task in a fraction of the time I anticipated and even scheduled a follow-up visit to deliver after sales services. Again, R4S performed up to its reputation from beginning to end, and I will refer you to everyone I know who needs their HVAC maintenance services or spare parts.

The contractor completed two days' load of service in one day, staying late and working hard! They're really decent men. Very well-behaved. Person A gave me advice on how to improve the efficiency of my ducting after their cleaning and sanitation process done. R4S is a great firm with great people.
It was a pleasure to work with R4S. They were really professional, punctual, and well-trained, as well as providing exceptional customer service. My new Chiller spare parts that they have installed and the maintenance services has exceeded my expectations. Highly recommended!
