AC Installation

New central air conditioning system installation, replacement of aging units, and system upgrades for improved efficiency

💰 $4,200–$9,500 ⏱ 1–2 days for standard installation; longer if ductwork modification needed ⚡ Plan ahead — install before summer

⚠️ Warning Signs You Need AC Installation

  • ⚠ AC unit is over 15 years old — efficiency has declined significantly and repairs will become more frequent
  • ⚠ Repair quotes exceed 50% of the cost of a new system — the "replace vs repair" threshold
  • ⚠ R-22 (Freon) refrigerant system — R-22 is no longer manufactured and recharging is very expensive
  • ⚠ Comfort complaints throughout the home — rooms that never cool properly despite regular maintenance
  • ⚠ Energy bills have increased year-over-year with no increase in usage or rate changes
  • ⚠ HVAC system requires multiple repairs per season — a sign of systemic end-of-life failure

What to Do: Step-by-Step

  1. 1 Get a load calculation (Manual J) from your contractor — right-sizing your AC is critical; bigger is not better
  2. 2 Obtain at least 3 quotes from licensed, insured HVAC contractors before committing
  3. 3 Verify the contractor pulls the required permit and the installation is inspected by a local building official
  4. 4 Choose a SEER2 rating appropriate for your climate — 16–18 SEER2 is the sweet spot for Sunbelt homes
  5. 5 Consider variable-speed or two-stage compressor systems — they cost more upfront but save significantly on energy bills
  6. 6 Inspect your existing ductwork before installation — leaky or undersized ducts reduce any new system's performance by 20–40%
  7. 7 Register your new system for the manufacturer warranty immediately after installation — most require registration within 60–90 days
