Use a smoke pencil or incense stick around windows, slides, steps, pass-throughs, and plumbing chases to reveal sneaky air movement. Replace tired weatherstripping, adjust latches, and seal penetrations with butyl and quality caulk. Consider foam gaskets for electrical outlets on exterior walls. A simple door-sweep upgrade can change nighttime comfort dramatically. Keep notes, label fixes, and re-test after each repair. If your pet insists on sitting by one corner, trust the furry meteorologist; investigate that chilly spot and reclaim your warmth.

Layer solutions for windows and underbelly to capture steady gains. Reflective window inserts cut radiant loss, while thermal curtains and magnetic covers add convenience. Coroplast skirting, foam board, or an inflatable skirt reduces undercarriage wind. Add pipe insulation to exposed sections and consider insulating rugs over cold floors. Inspect factory insulation voids near wheel wells and service panels. Keep materials removable for shoulder seasons. Record temperatures inside and outside to see real improvements, celebrate progress, and refine your setup without wasting energy or time.

Before the first frost, vacuum furnace compartments, inspect burner flames, and test airflow at each register. If you rely on catalytic or radiant heaters, confirm ventilation paths and check carbon monoxide and propane detectors. Heat pumps help above freezing, but plan for a switchover strategy when temperatures plummet. Carry backup electric heat if hookups allow and keep a small parts kit: igniters, fuses, and spare filters. A professional inspection before peak season provides peace of mind, smoother starts on frigid mornings, and fewer surprises when storms arrive.
