What does AC replacement cost in Fort Bend County?
A complete AC or heat pump replacement in Fort Bend County typically runs about $5,500–$14,000 installed, depending on system size, efficiency (SEER2) and your home's ductwork. These are planning ranges, not quotes — your exact price is quoted in writing before any work.
What drives the price
- System size (tonnage): a larger home needs more capacity, which costs more.
- Efficiency (SEER2): higher-efficiency equipment costs more upfront and uses less energy over its life.
- Ductwork: if existing ducts are undersized, leaky or need modifying, that adds to the job.
- Equipment type: a heat pump that replaces both AC and furnace differs from an AC-only swap.
- Add-ons: a new thermostat, air handler, line set or indoor air quality equipment.
Planning ranges (not quotes)
- AC or heat pump replacement, complete & installed: $5,500–$14,000
- Furnace / heating replacement, complete & installed: $3,500–$8,500
- Ductless mini-split, per zone supplied & installed: $3,000–$7,000

Common questions
How much does it cost to replace an AC in Fort Bend County?
Most full AC or heat pump replacements here run about $5,500–$14,000 installed, depending on size, efficiency and ductwork. That's a planning range — your exact price is quoted in writing before any work, and financing is available.
Is a more efficient AC worth the extra cost?
Often, over the life of the system. Higher-SEER2 equipment costs more upfront but uses less energy every summer — and in Fort Bend's long cooling season those savings add up. A written estimate can show the payback for your home.
