    I can’t recommend O&R more highly. Affordable, friendly, professional and great service. They even helped me out by changing my filters for me. I have great peace of mind knowing O&R are there when I call.

    Orlando is amazing! Called at 8:00 and he was here by 10:00 to work on our AC! Will definitely use again in the future!

    Orlando and his team were amazing! Replaced our AC and furnace within 5 days when our old unit died in the summer. Very fair pricing and great quick work. Would highly recommend!!
