Most of us assume that heating and cooling homes is the work of our HVAC system. But an HVAC system works in tandem with a home’s insulation and envelope, which include the outer walls, windows, doors and other openings.

When air leaks through a home’s envelope or is compromised due to under-insulation, HVAC systems must work harder to maintain a comfortable environment.

Even though you may lower your thermostat in the winter and raise it in the summer if your home is under-insulated and has leaks, your HVAC system may be carrying a big load. By sealing air leaks around your home and adding insulation, you can increase comfort, save energy and lower utility bills.
