In June 2023, I bought a 2002 square-foot Tudor style home that was built in 1929. I really wanted central air-conditioning, but knew it would be problematic because of the plaster ceiling and walls. Not only that, but I have a boiler and radiator heating system system and I wasn't willing to replace it in lieu of a furnace for central air and heat. I did get one bid and that was for mini splits only and then only in 2 bedrooms upstairs and one unit in the dining room. The price was astronomical and I thought I would be resigned to using portable air-conditioning units during the hot months. That was, until I found Jeff. We scheduled an appointment for a free estimate, and he determined that he could install central air conditioning in all four bedrooms and the bathroom upstairs by placing the air-conditioning unit in my attic. The other company I had give me an estimate never even thought of that concept. The possibility of having central air downstairs wasn't an option because of a number of different obstacles. I have two mini splits downstairs, situated in rooms that will allow for maximum cooling of every room on the lower level. Tyler, Ethan, Hunter, and Jeff, himself, were meticulous and took pride in their workmanship. They went to great lengths to ensure that my flooring was covered and everything was cleaned up at the end of the day. I've had a lot of work done at my house since last June, and this crew was the most polite, thorough, and hardworking as I've seen! I would give Optimal Heating and Cooling 100 stars if I could! read more
