What drives the price
- Size (tons): larger homes need more capacity. A load calculation (Manual J) should set the size.
- Efficiency: higher SEER2 units cost more upfront and can cost less to run.
- Matched system: replacing just the outdoor unit vs the coil and furnace/air handler too.
- Ductwork, electrical and permits.
- Rebates: some Texas utilities pay incentives; see rebates and tax credits.
