I am a real estate agent and Will put in a new furnace for one of my clients. He did a great job and they were very happy with his work.

Mike D.

Will is experienced, reliable, and a great communicator. I hire and refer him whenever I get a chance!

Bethany O.

We had two other guys come out and couldn’t figure out the problem.Will figured it out right away. Will made us feel very comfortable. He always communicated every step of the way and we are very happy with his work. I would recommend Will to everyone I know!

Amy M.

My experience with Cozy Conditions was amazing. The quality of the product was second to none. The work was done very efficiently and without issue. I would recommend them to anyone.

Benjamin B.

Will is as good they get! He knows his stuff and is as fair and honest as they come. He’s a true family man who works hard for not only his family but also yours!!!


Will was very professional – he explained all the details and worked efficiently. The price was awesome too.

Francisco E.

Will replaced a furnace for me located in my basement. I was pleasantly surprised on how neat and clean the installation went. No issues and the furnace works great. I will have Cozy Conditions back this spring to do a service check on my AC.

Denise M.

We would gladly hire Cozy Conditions again for a project and would recommend them wholeheartedly. The work was done with care, they kept their commitments, and the work area was tidy and orderly.

Michelle L.

It was time to replace our existing unit. We got several bids, and so happy we went with Will. He was very informative, honest, and we really appreciated that. The timeline/install was exactly what he had said. I highly recommend Cozy Conditions! Thank you Will!!

Kimi L.

After screening several contractors and well-known HVAC businesses, it was clear to me that Cozy Conditions was the best overall value. I received daily updates on the progress of the job and Will always checked in to make sure I didn’t have any questions.

Clifford H.

Will not only did an excellent job of both my installations, but also charged me a rate which was extremely reasonable. He installed a mini-split system on the roof of my office building and an exhaust fan in the men’s restroom. He is now my regular HVAC tech.
