How to Build a Box Fan Air Purifier
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.
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.
90% of homeowners could be using less energy to heat and cool their homes.
