upgraded-hvac-system03

This project really came to life after the installation was completed. The customer decided to upgrade his Heating and cooling system to a 2 stage air conditioner and 2 stage furnace with a variable speed supply air motor. These enhancements allows for ultimate humidity control and allows equipment to operate at a much lower ratio than standard on/off equipment.
