How Much Does HVAC Repair & Replacement Cost? (2026 Guide)
Updated April 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
A service call covers a technician's time to diagnose the problem. It does not include repairs. Many contractors apply the service call fee toward the repair if you proceed — confirm this before scheduling.
| Service type | Typical cost |
|---|---|
| Standard service call (diagnosis only) | $75–$200 |
| Emergency / after-hours service call | $150–$400 |
| Seasonal tune-up (AC or furnace) | $80–$175 |
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 for utility rebates — many utilities in Georgia, Florida, and Colorado offer $200–$800 on high-efficiency equipment. Ask about manufacturer rebates on new model-year equipment.
