Air leaks in your central Arizona home can be a big source of energy loss. They not only drive up the cost of cooling and heating your home, but they also make it more difficult to keep your house comfortable for your family. Fortunately, air-sealing is relatively simple and can give you a big return on your investment via lower utility bills.

Air sealing is a project many homeowners tackle themselves, but an experienced contractor may be able to find and seal many air leaks that are not readily apparent to a casual observer. Following are some of the most common places to find air leaks in a typical Arizona home and the best ways to seal them:

  • Door and window frames. When doors and windows are installed, the spaces around the frames should be insulated before the finishing touches are put on the walls. If you can see or feel cracks around your doors or windows, seal them with caulk or expanding foam insulation.
  • Moving parts of doors and windows. Apply weather stripping where the moving parts of doors and windows seal against their frames when they are closed. Install door sweeps to block drafts beneath doors.
  • Attic access. Your attic access hatch can be a big source of energy loss if it is located inside your home’s conditioned space. Apply weather stripping to seal air leaks around the hatch and insulate the attic side of the hatch to minimize heat conduction.
  • Holes in exterior surfaces. Openings in your outside walls, main floor, or ceiling where plumbing or electrical wiring comes into your house can be a big source of air leaks in your home. Use caulk or expanding foam to seal around pipes, vents, and wiring. Be aware of fire-safety issues when sealing the space around chimney flues or furnace vent pipes.
