TESTIMONIALS

What do our clients have to say about us?

  • I am writing to commend the contractors that RST Thermal helped us find on their excellent work. Despite having to work on the hottest day of the year, they finished the project without incident. We really appreciate everyone's efforts at RST Thermal!


    Rob Tseng, CEO, Tseng Enterprises
  • The contractors referred by RST Thermal did a fantastic job installing a new boiler in our apartment building. We have been working on renovations for some time, and we were concerned that the faulty boiler would be a major setback. Their staff worked so quickly that we didn't fall a single day behind schedule.

    Mark Tan, Building Owner
  • We were recommended to RST Thermal when we needed to upgrade the mechanical system in our home and didn't know where to turn. After we spoke to some of their people we knew we'd made the right decision. The staff listened to our needs and explained what would be involved in the process. They kept in contact with our installing contractors. The results speak for themselves. We are comfortable and we are saving a lot of money.
