A central AC replacement in Phoenix or similar hot-climate cities runs $6,000–$13,000. Most home warranty plans cap HVAC coverage at $1,500–$6,500. Understanding that gap — and which company minimizes it — is the core decision.
What Central AC Coverage Includes
Most plans cover central AC components:
What's Excluded
Window AC units
Portable and window-mounted AC units are excluded from all standard plans. They're portable appliances, not built-in systems.
Refrigerant recharge
Most companies exclude refrigerant recharge or apply a small sub-cap. AHS includes it — a significant advantage for older systems using R-22.
Rust and corrosion
Excluded by most companies. AHS includes it — another reason AHS is often the top pick in humid climates with older equipment.
Maintenance failures
Dirty coils, clogged filters causing compressor stress — grounds for denial if the technician documents maintenance neglect. Annual tune-ups create your paper trail.
Improper prior repair
Prior HVAC work by an unlicensed contractor can void coverage on those components. Always use licensed contractors.
AC Coverage Cap Comparison
Phoenix average central AC replacement (3-ton): $6,000–$13,000. The gap between cap and actual cost is your out-of-pocket exposure.
| Company | AC Cap | Potential Out-of-Pocket |
|---|---|---|
| AFC Home Club | ~Actual cost | $0–$2,000 (schedule-based) |
| Old Republic | $6,500 | $0–$6,500 |
| AHS | $5,000 | $500–$8,000 |
| 2-10 HBW | $5,000 | $500–$8,000 |
| First American | $3,500 | $2,000–$9,500 |
| Liberty | $2,000 | $3,500–$11,000 |
| Cinch | $1,500 combined | $4,000–$11,500 |
Gap estimates based on Phoenix market; varies by region and system size.
Mini-Split Coverage
Ductless mini-split systems (Mitsubishi, Daikin, LG, Fujitsu) are covered in modern comprehensive plans. Older plan contracts may not specifically enumerate them — if you have mini-splits, verify the coverage language explicitly before purchasing.
Mini-split outdoor compressor units are expensive ($800–$2,500 for the unit alone). If your home relies on ductless cooling, the HVAC cap is your most important comparison point.
Annual HVAC Maintenance — Your Claim Protection
Most warranty companies require that you maintain your HVAC system to keep coverage valid. A documented annual tune-up is your defense against "maintenance failure" denials.
Practical step: Schedule an annual AC tune-up ($75–$150) by a licensed HVAC technician. Keep the receipt. If your compressor fails three years later, you have documentation that the system was maintained — making it much harder for the company to cite "maintenance failure" as a denial basis.
