EXCELLENT Based on 52 reviews Posted on Alex V.Trustindex verifies that the original source of the review is Google. I bought a new HVAC in 2020. The whole system went bad due to rolling black outs, spring 2023. I called 3 HVAC companies and non could find out why my system wouldn't run properly. Called JJJ Techs. They came out within 24 hours and found out that both Mother Boards were fried from the blackouts. Juan came out and said their were NO mother boards in the country for the Blower. I even called 2 warehouses my self and confirmed this as well. There was a 6 month wait time for new mother boards. The Blower need to be replaced in which I had to pay for at dealer cost. The condenser mother board was free and when installed the mother board was bad. So a second board had to be replaced. Juan and JJJ Tech where incredible and i recommend everyone to them and on social media too. Fantastic work..... I use them all the time.....
