Your technician, Jonathan Santana was awesome. My husband was not home and Jonathan was very understanding. Even though there was a mix up with the service connection from Rheem, Jonathan assisted without hesitation. His help made my follow up conversation with Rheem much more productive. Please thank Jonathan for me.Best regards, Lisa

I had a very good experience with them installing a heat pump to complement our gas furnace. Vlad, the project manager, did the initial site review and inspected the existing setup in detail. He made sure that all our concerns about the project as well as about the current system were addressed (we did not have an AC before so it was a more complicated install). Price was comparable to other quotes we got -- but the proposed systems were closer to what we actually wanted. We even got a post-season promotion so the choice was easy.Kareem and his install crew were also great -- he told me in detail what they were going to do and answered all my questions about where and how things are going to go. They were working hard all day to finish the project and making sure everything was cleaned up at the end.Highly recommend!
