Schmidt Mechanical has installed 2 units in my home. The first was in my home that did not have central air. They installed a new unit and duct work. They did such a good job that I reciently used them again to install a seperate unit for a master bedroom addition. Both jobs were always kept clean and were on schedule. They were great from the initial evaluation, install and service as well. I highly recommend Schmidt Mechanical for any air conditioning and/or heating needs
