Grab a notepad, incense stick, and flashlight. Feel for moving air around windows, baseboards, outlets, and attic hatches while smoke traces hint at leaks. Note noisy appliances, hot chargers, and inconsistent temperatures, building a prioritized list that respects both your budget and your schedule.
Sort findings by cost, effort, and savings potential. Sealing obvious gaps, swapping bulbs, insulating pipes, and adjusting thermostats typically pay back faster than appliance replacements. Celebrate quick wins to build confidence, then allocate small monthly amounts toward the next improvement on your personal roadmap.
