Luxaire furnaces are covered by warranties from the manufacturer. The exact terms and coverage details vary between products, so it's best to contact a dealer with specific warranty questions.
Luxaire furnaces come with a standard 10-year warranty on parts, compressors and heat exchangers. According to Furnace Compare, these warranties must be registered within 90 days, or coverage is reduced to five years. Luxaire dealers offer extended warranties with furnace purchases, which can cover parts, labor, or both for up to 10 years. These extended protection plans cover an unlimited number of service calls and repairs, and they are purchased separately for a one-time fee.
