We treat cooling a little differently than heating because of the way the human body works. Our bodies carry their own little heat plant around within us - all the time. To cool, we perspire and count on air movements to evaporate our sweat and cause us to cool. Convective air movements facilitate that. So what we have come up with is a way to heat and cool a home that is friendly to the average homeowner and to do it yourselfers and still maximizes your comfort.


On a cooling system, the basic components are a chiller or compressor, a heat exchanger, an insulated piping system, a fan coil and a thermostat. The chiller unit sits outside and the heat exchanger unit is located within the chiller. Our heat exchangers use a fluid that is a chilled water/glycol mix. The water/glycol mixture flows through the insulated pipes and is drawn through a fan coil that passes room air across the chilled water/glycol mix and blows cool air into the room. The reason we use insulated piping is mostly due to condensation. When you run cold water through a pipe, it is a lot like a glass of iced tea on a hot day. The outside of the glass is cooler than the air and humidity condenses on that cold surface. You would not want that in a piping system in your house, so you have to insulate it. In a typical cooling cycle, the thermostat in a room or an area calls for cooling and that turns the fan on. The fan-coil unit opens a valve and draws cool fluid from the chiller and compressor until the thermostat is satisfied in that area and shuts itself off.
