Home Depot is a one-stop shopping destination for all things related to home improvement, but you've likely visited the store for more than just renovation supplies. But if you pick up the wrong tool or a ceiling fan that doesn't fit your space, Home Depot has a generous return policy for most items, but if you're a regular customer, take note — the store recently changed the rules for a few products. The home improvement store offers an even shorter return window for some items, allowing only seven days for air conditioners, dehumidifiers, and gas generators. Effective July 2026, Home Depot added pumps, portable evaporation products, and portable heaters to its seven-day return policy. For many products, the store's typical 90-day return policy remains in place.
