How Much Does HVAC Repair & Replacement Cost? (2026 Guide)
Reviewed October 2026 · 10 min read
HVAC costs vary more than almost any home service category. A service call might run $100, or the technician's visit might reveal a problem that turns into a $10,000 system replacement. Understanding the cost ranges for common HVAC work helps you recognize a fair quote, budget realistically, and avoid being caught off guard.
HVAC Service Call Cost
Ask what the diagnostic visit covers, whether travel is billed separately, and what you owe if you decline a repair. Confirm any after-hours charge and whether a visit fee is credited toward approved work.
Our HVAC repair cost and diagnostic fee guide explains the cost factors and questions to ask before scheduling.
AC Repair Costs by Component
Once diagnosed, repair costs vary widely by what failed. Use the rule of thumb: if a single repair exceeds 50% of replacement cost and the unit is over 10 years old, replacement is often the better financial decision.
| Repair type | Typical cost range |
|---|---|
| Refrigerant recharge (R-410A) | $200–$500 |
| Capacitor replacement | $150–$350 |
| Contactor replacement | $150–$300 |
| Thermostat replacement (including labor) | $150–$350 |
| Blower motor replacement | $400–$700 |
| Evaporator coil replacement | $800–$1,800 |
| Condenser coil replacement | $700–$1,500 |
| Compressor replacement | $1,200–$2,800 |
| Condensate drain line clearing | $75–$250 |
| Circuit board replacement | $300–$700 |
Full AC System Replacement Cost
A central AC replacement includes the outdoor condensing unit, indoor air handler or coil, and labor. Ductwork modifications and electrical upgrades are additional.
| Home size | Equipment tier | Installed cost |
|---|---|---|
| Under 1,500 sq ft (1.5–2 ton) | Builder-grade (14–16 SEER2) | $4,000–$7,000 |
| 1,500–2,500 sq ft (2.5–3.5 ton) | Mid-tier (16–18 SEER2) | $6,000–$10,000 |
| 2,500–4,000 sq ft (4–5 ton) | High-efficiency (18–21 SEER2) | $9,000–$14,000 |
| Large home / premium equipment | Variable-speed, inverter-driven | $12,000–$18,000+ |
Prices reflect equipment + labor. Ductwork repair, electrical upgrades, and permit fees ($100–$400) are additional.
Heat Pump Installation Cost
| System type | Typical installed cost |
|---|---|
| Air-source heat pump (standard) | $5,500–$12,000 |
| Air-source heat pump (high-efficiency) | $10,000–$16,000 |
| Dual-fuel heat pump (with gas furnace backup) | $8,000–$15,000 |
| Mini-split (single zone, ductless) | $3,000–$6,000 |
| Mini-split (multi-zone, 3–4 zones) | $8,000–$14,000 |
Furnace Replacement Cost
| Furnace type | Efficiency | Installed cost |
|---|---|---|
| Gas furnace (standard) | 80% AFUE | $2,500–$5,000 |
| Gas furnace (high-efficiency) | 95–98% AFUE | $4,000–$8,000 |
| Electric furnace | N/A | $1,800–$4,000 |
City-Specific Pricing Context
Atlanta, GA
Typical service call
$100–$175
Typical AC replacement
$7,500–$10,500 installed (3-ton, mid-tier)
- •July and August are peak demand months — emergency replacement premiums add 15–25% over off-peak.
- •Atlanta's high humidity makes proper equipment sizing critical: oversized AC short-cycles and leaves humidity uncontrolled.
- •Many older Atlanta homes have R-22 refrigerant systems. R-22 is phased out — recharging is expensive; replacement is almost always the better decision.
Tampa, FL
Typical service call
$90–$160
Typical AC replacement
$7,000–$10,000 installed (3-ton, mid-tier)
- •Cooling season is essentially year-round; high humidity demands properly sized equipment.
- •Hurricane and storm events create surge demand — contractors can be backlogged 1–2 weeks post-storm.
- •Florida's robust licensing enforcement means the contractor pool is generally well-credentialed.
Denver, CO
Typical service call
$90–$180
Typical AC replacement
$6,500–$10,000 installed (3-ton, mid-tier)
- •High altitude affects HVAC equipment performance — some equipment must be derated; confirm contractor accounts for elevation.
- •Denver's dry climate means humidity is less of a concern than in Atlanta/Tampa, but proper sizing still matters for efficiency.
- •Cold snaps below 0°F are not uncommon — any heat pump should include reliable backup heating.
Frequently Asked Questions
- How much does a central AC replacement cost in 2026?
- A central AC system replacement typically costs $5,000–$12,000 installed for an average-sized home. High-efficiency variable-speed systems and larger homes can push costs to $15,000–$18,000. Get 3 written quotes with specific equipment and model numbers before committing.
- Is it worth repairing a 10-year-old AC unit?
- The general rule: if the repair costs more than 50% of replacement cost and the unit is 10+ years old, replacement is often the better financial decision. Also: units running R-22 refrigerant should typically be replaced because R-22 is no longer manufactured and recharging is very expensive.
- How much does AC repair cost for a refrigerant recharge?
- Refrigerant recharge (R-410A) costs $200–$500. However, a recharge alone does not fix the underlying problem — refrigerant levels do not drop from normal use; low refrigerant means a leak. A proper repair includes finding and fixing the leak first, adding $300–$600+ to the total.
- How can I reduce HVAC replacement costs?
- Get quotes in the off-season (fall for AC, spring for furnaces). Ask about previous-model equipment. Check your utility and state energy office for current rebates, including pre-approval and equipment requirements. Ask manufacturers or contractors for written terms on any current promotion.
