Had a crew out to do annual service and to figure out how to clean up a piping mess created by another contractor when they installed a Unico high velocity mini-tube sytem in my 1917 home. There was a huge speaghetti mess of tubes all over the basement which was impacting the usability of the basement. One of the crew on site has installed hundreds of Unico systems, and spoke with Unico technical services as part of developng a solution. Not only does the basement look WAY better, but after they rebalanced the system the whole A/C works WAY better. Tom and crew are the Mike Holmes of HVAC - they make it right.
