Highly recommend! Great service, courteous and reasonable cost! Andrei fixed my unfixable PTAC!

George was fast in his response when scheduling a service and Andrei performed boiler maintenance for us after we noticed that the top floor of our townhouse wasn't heating. He helped check our system

OptimizeAir Installed a new steam boiler controller. Service person was very professional, he did an amazing job at a fixed, agreed upon price. I would hire them again.
