Five Star Mechanical is an HVAC service and contracting company that institutes "best clean-tech practices" in all elements of its work and products. We sell and install Bes-Tech's Digi RTU controllers in Western WA. The Digi RTU controller will lower commercial building's heating and air conditioning demands from 40-60%. We provide a unique HVAC preventative maintenance program called the Sustainable HVAC Preventative Maintenance Program. It is guaranteed to lower overall energy costs to a building owner/tenant while providing a less expensive annual maintenance program. Last, in early 2015 we will be offering Western Washington the most cost-effective solar space heating collector yet developed. We are Sunreps' distributor and installer for the first ever fabric transpires solar collector. The collectors pre-heat a commercial building's make-up air which reduces the amount of fossil fuel needed to accomplish the same task.
