We have had multiple experiences with United Mechanical Inc and they were all fairly positive. Most recently they installed a full unit in a home that I am working on. They did the outside and inside unit, everything went very smoothly and I'm happy with how fast the work was completed. They made sure to clean up after themselves and communicated very well with me through every step of the way. Pricing was a little higher than I expected but that's the only issue I can think of. I would highly recommend them and would definitely use them again.
