What Affects Your HVAC Replacement Cost?

• Home Size & Load — We size your system with a Manual J load calculation, not a rule of thumb. A larger or leakier home needs more capacity.
• Efficiency Rating — Higher SEER2 (cooling) and AFUE (heating) ratings cost more upfront but cut monthly energy bills. Variable-speed equipment adds comfort and cost.
• Ductwork Condition — Sound, well-sealed ductwork keeps costs down. Damaged, undersized, or missing ducts that need repair or new runs add to the install.
• Equipment & Permits — Brand, model features, line-set length, electrical upgrades, and local permits all influence the final installed price.
