What drives HVAC prices
- Region and labor rates: major metros cost more.
- Season: peak summer and winter mean busier crews and less negotiation.
- Efficiency and technology: variable-speed and high-SEER2 equipment cost more up front.
- Access: attics, crawl spaces and rooftop units add labor.
- Extras: new ductwork, line sets, electrical upgrades, pads and permits.
Ways to save
- Get three written quotes with model numbers.
- Ask your utility about rebates, and check state programs.
- Replace in spring or fall, when contractors are less busy.
- Ask about financing terms carefully. "0%" offers can carry high deferred interest.
