Lennox FAQs

- Installed price varies more by capacity, efficiency, indoor equipment, ducts, electrical work, controls, labor, and market than by the outdoor badge alone. Compare complete written scopes.
- What should I compare in a Lennox quote?
- Compare both model numbers, AHRI match, load calculation, ducts and line-set scope, controls, refrigerant, permits, startup, parts warranty, and contractor labor coverage.
