What Our Clients Say

Phil Russel

Our 27 year old heating system died and needed replaced. Leo removed the old system and installed a new heat pump and furnace system that is much more efficient than the old one. We appreciate his excellent work and all done in 2 days! We highly recommend him! This is Phil Russell and I approve this message!

Sherae Quattrocchi

We received great service from Reliant. Our furnace was experiencing some issues and Leo came to our home on 3 separate occasions (without billing us!) because he was focused on discovering the problem. He also followed up with us to insure that we were happy with the work that he and his team provided.

David Dardano

Leo was great. He knows his stuff but most of all we had some up front issues with the contractor that put the AC coil in when the house was built. Leo started the job and had to stop because of this. Leo was very patient while I dealt with the other contractor and was Jonny on the spot after the fix to get the job done. AC at last! Use Leo!
