In 2007 they installed new HVAC in my condo that had a furnace from 1986 and no central air. I got estimates from 3 firms and went with Engineered because they gave me the best price and, were patient enough to explain why I needed this or that. 14.5 years later, they discovered that my AC wasn't working because the compressor had somehow gotten wet and had corroded and, my attic ducts were torn and not performing well. That'll teach me to not have it serviced regularly! Jeff and crew were at my home within 48 hours after my initial call and 3 hours later, my new AC is PERFECT!!!!!!! Truly, I will

I work for a Property Management company, Ive contracted Engineered Comfort Heating & Air and I must say I am not disappointed. These men are polite, professional and fast. They contact our tenants immediately and address repairs/replacements as needed. I would recommend them and know you will not be disappointed!

My air conditioner stopped blowing cool air. I got a recommendation to call Oscar at Engineered Comfort. A team was sent out immediately to assess the repair on Friday. I ended up replacing the entire unit. A team of very professional & kind men showed up at the promised time on Monday. There was two men working inside my home and two on the roof with a crane. They worked very well together and completed the work in under 4 hours. Not only did they take great care of installing the new unit, they were very careful with my furniture. They covered my wood floors and very carefully removed the old

I asked for a quote on Sunday evening and by Wednesday noon I had a whole new AC unit. I was given a range on a high level quote and the firm quote came within the set range. This tells me these guys know what theyre doing. The scope of the work replaced the heat pump/air conditioner as well as the air handler in the living quarters. I was given a whole new door for the air handler. Also, a thermostat was included in the installation. They installed an electrical line with protective conduit. The job required a crane to deliver the unit and remove the old one. There were two guys working on
