About Us


BobFounded in 1986 by Robert Zemke a mechanical contractor with roots from the solar energy and geothermal heating and cooling industries, we have developed a team of experts dedicated to designing, installing, and servicing your next high efficiency heating and cooling system. We are committed to providing outstanding value, first-rate service, and the comfort and energy savings you are looking for.

Take confidence in knowing that we will make every effort to treat your home as if it were our own. Our installer’s motto is to do the “best job we know how to do each and every time.”




We have licensed journeymen service technicians who are courteous, neat, and prompt. They have spent years training to get the knowledge needed to fix your air conditioner, geothermal or air source heat pump, gas furnace or light commercial unit the right way the first time. Each year we upgrade our service skills by attending training sessions at the local vocational tech schools, manufacturer schools delivered by Waterfurnace, Climatemaster & Rheem. We always fully guarantee our service and will gladly recheck any service problem at no cost for 30 days.  We offer “worry free” planned maintenance agreements with free filters, priority emergency service, and written check lists.


We have the knowledge and the software to do custom heat-loss and cooling-gain calculations on residential and light commercial retrofit and new construction projects. We also design a wide variety of air distribution and exhaust systems. We have more than 20 years of experience designing open and closed loop geothermal heat pump systems. We are certified to design radiant floor heating systems and multiple zone systems. Our software has the unique ability to put various types of systems side by side, so you can see the comparative operating costs and payback of different traditional heating, cooling, and hot water heating options.


From a simple air conditioner change outs to retro fit gas furnaces, air source and geothermal heat pumps, multiple zone custom houses, offices, roof top light commercial restaurants, banks, and nursing facilities take confidence from the fact that our installers have “been there, done that.”
