Heating, Ventilating and Air Conditioning design is a keystone of our design services. Intelligent energy use has been a design goal at Heapy long before the "energy crisis" of the early 1970's. We have conceived many innovative but simple systems to heat, cool and light buildings with a minimum of energy input. Heapy Engineering has conducted numerous energy audits, and has followed through with implementation of many of these. We strive to make each project cost-effective and functional, often providing on-site assistance or computer monitoring from our office to accomplish these goals.
