HVAC Repair & Replacement Cost Guide [2026]

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 Costs

A service call covers a technician's time to diagnose the problem. It does not include repairs.

Service type	Typical cost range
Standard service call (diagnosis only)	$75–$200
Emergency / after-hours service call	$150–$400
Seasonal tune-up (AC or furnace)	$80–$175

Important: Many contractors apply the service call fee toward the repair if you proceed. Confirm this before scheduling — not all do.

AC Repair Costs

Repair type	Typical cost range
Refrigerant recharge (R-410A)	$200–$500
Capacitor replacement	$150–$350
Contactor replacement	$150–$300
Thermostat replacement	$150–$350 (including labor)
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

Rule of thumb: If a single repair exceeds 50% of the cost to replace the system, and the unit is more than 10 years old, replacement is usually the better financial decision.

Full AC System Replacement Cost

Home size	Equipment tier	Installed cost range
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 above are for equipment + labor. They do not include ductwork repair, electrical panel upgrades, or permit fees (typically $100–$400).

Heat Pump Installation Cost

A heat pump provides both heating and cooling. In the South (Atlanta, Tampa), heat pumps are often the most cost-effective choice because winters are mild enough for year-round heat pump efficiency.

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, no duct)	$3,000–$6,000
Mini-split (multi-zone, 3–4 zones)	$8,000–$14,000

The Inflation Reduction Act provides a 30% federal tax credit (up to $2,000) for qualifying heat pump installations. See our HVAC Tax Credits & Rebates Guide for current details.

Furnace Replacement Cost

Furnace type	Efficiency	Typical 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

HVAC Costs in Atlanta, GA

Atlanta's hot, humid climate creates high demand for HVAC services. July and August are peak demand months — scheduling an emergency replacement during peak season adds 15–25% to labor rates.

• Typical service call: $100–$175
• Typical 3-ton AC replacement (mid-tier): $7,500–$10,500 installed
• Many older Atlanta homes run R-22 — phased out and very expensive to recharge; systems using R-22 warrant replacement

Getting an Accurate Quote: What to Require

The most common reason HVAC quotes vary by thousands of dollars for the same job is that contractors are quoting different things. Require every quote to include:

1. Specific equipment brand and model number
2. SEER2 rating (for AC or heat pump)
3. AFUE rating (for furnaces)
4. Labor included vs. excluded
5. Permit fees (included or extra)
6. Disposal of old equipment (included or extra)
7. Warranty on labor and equipment separately
