The art of HVAC is found in mitigating heat transfer. One of the tools to help contractors in this area is insulation. Before suiting up and insulating everything in the house, contractors should understand the science to insulation — how it balances out what is necessary not only for the house itself, but also for the heating and cooling systems within the house. In essence, proper insulation can yield a win-win-win situation for the HVAC system, the customer, and the contractor.
