Isolate Unused Areas
Closing heating/air conditioning dampers and sealing exterior windows can isolate spaces that are not occupied by people or equipment.
Tighten Door and Window Frames
This will help minimize unwanted air leaks. Automatic door closers should be periodically adjusted.
Cracks may occur in foundations, walls, roofs and around openings (windows, doors, skylights, etc.). Normal use, thermal expansion and contraction, material aging, foundation settling, or earthquake damage can cause these cracks. Glass fiber, expanding foam, silicone, and acrylic sealants can be used to repair cracks or restore damaged seals in the building envelope.
Install Air Conditioner Covers
Placing exterior covers on window-mounted air conditioners during winter months will prevent air leakage both through and around the unit.
Installing rubber blade or brush-type door sweeps on the bottom of exterior doors, or weather-strips on thresholds, limits airflow beneath the door. Rubber strips can also be used between double doors. Weather-stripping can be added around door frames with metal or plastic "V" strips or adhesive backed foam strips. Windows that open, particularly double hung windows, may also benefit from thin foam weather-stripping.
Shade Windows From Direct Sunlight
Interior window blinds and shades can be turned to deflect direct sunlight. This will reduce temperature build-up in the building.
Regular HVAC System Maintenance and Cleaning
Periodically check the flame and replace or clean the air filters and intake screens for gas-fired heating equipment. Properly adjusted burners, and clean air filters and intake screens can help reduce fuel cost by 5-10%.
