Replace filters, vacuum burners gently, confirm flue integrity, and schedule combustion analysis to verify safe, efficient operation. Smart thermostats with learning features prevent overshoot and short cycling. With carbon monoxide alarms tested, you gain both savings and peace as nights turn crisp and demanding.
Use mastic, mesh, and patience, not flimsy tapes that dry out. Prioritize joints near the air handler and long runs crossing unconditioned spaces. Even partial sealing boosts delivered airflow, stabilizes room temperatures, and chops wasted energy that otherwise escapes silently into attics, crawlspaces, and garages.
Close a sheet of paper in the door and tug; if it slips easily, the seal fails. Install adjustable sweeps and compression gaskets, then admire quieter rooms and calmer temperatures. This inexpensive, satisfying project returns value daily through winter and cushions shoulder seasons beautifully.
