    I love the 5 star service from this company. They put a brand new hvac system in my house and do the yearly maintenance. Highly recommend using this company. The owner Mark is very personable.

    Called for an estimate to do some work which did not include replacing 2 perfectly functional units. The tech took one look at it and then spent the next five minutes trying to convince me to purchase new units, instead of providing an estimate to do what I called him to do. So long story short, $89 for a quick look, and then several minutes of having to listen to a sales pitch. Even though I told him I was not interested in replacing fully functioning units. The best part is I never received the estimate I paid for. But got these two nifty $89 on the mark stickers slapped on my HVAC without my consent. Won't be using them for anything. Not even preventive maintenance.

    Omar was a good serviceman.He explained everything slowly and in layman's term so the average customer like myself got some kind of basic understanding of what he was checking for and doing.

    Cesar was amazing! His team came on time, got right to work while Cesar explained what was happening. They were extremely courteous and personable answering all our questions and concerns. He explained the new smart thermostat until we understood. They cleaned up really well. I would highly recommend Cesar and On the Mark to everyone.
