84. Ensure windows and doors are properly weather-stripped and use door sweeps.

86. Do not use roof-top power ventilators for attic exhaust as they may draw conditioned air from your home.

87. Have your HVAC system serviced once per year by a NATE-certified technician.

88. Monitor your home’s relative humidity in the summer. If it consistently stays in the 60 percent range or higher, ask your HVAC technician about lowering your central air conditioning unit’s indoor fan speed.

89. Ensure window A/C units are weather-stripped. Remove the unit in the winter and close and lock the window.

90. Remove and clean window A/C filter monthly
