We offer instant discounts on many ENERGY STAR® certified appliances and HVAC equipment. Instant discounts are savings already applied to the purchase price of the qualified product. There are no rebate forms to fill out or coupons to clip. To realize the savings for appliance products, purchase a qualified product from a participating retailer in the Potomac Edison – Maryland service territory. Instant discounts on qualified HVAC equipment require purchase and installation from a participating contractor in our Maryland HVAC program.
