The short answer
Low end
$150
Most repairs / tune-ups
$750
High end
$12,000+
In 2026, most HVAC repairs run $150–$900, AC tune-ups run $75–$200, and new system installations run $3,500–$7,500 (central AC) to $6,000–$12,000+ (full furnace + AC replacement). The biggest cost drivers are system tonnage (sized to your home), efficiency rating (SEER for AC, AFUE for furnace), and whether ductwork needs repair.
HVAC pricing has three distinct tiers: maintenance/tune-ups, repairs, and full-system installs. Most homeowners interact with HVAC pros for repairs first — and the repair-vs-replace decision is the highest-stakes one because a wrong call can cost thousands either way.
The U.S. residential HVAC market is dominated by central-AC + gas-furnace setups (the "split system"). Heat pumps are gaining market share fast — particularly in moderate-climate states + with the federal Inflation Reduction Act tax credits. Ductless mini-splits remain a smaller but growing segment, especially for additions, garages, and zone-heating retrofits.
System longevity is the lever that drives most cost-of-ownership math: a well-maintained AC lasts 15–20 years, a furnace 15–25 years, a heat pump 12–15 years. Replacing a 10-year-old system before it breaks during a heat wave is significantly cheaper than emergency installation.
HVAC service costs by scope (2026)
| Service | Typical cost | Notes |
|---|---|---|
| AC tune-up / maintenance | $75 – $200 | Annual service recommended |
| Furnace tune-up | $75 – $200 | Pre-winter check, gas safety inspection |
| AC repair (minor) | $150 – $500 | Capacitor, contactor, thermostat |
| AC repair (major) | $500 – $1,500 | Compressor, evaporator coil, refrigerant work |
| Refrigerant recharge (R-410A) | $200 – $600 | Plus leak detection if leak suspected |
| Furnace repair | $150 – $900 | Ignitor, blower motor, heat exchanger |
| New central AC unit (install) | $3,500 – $7,500 | 2,000 sq ft home, mid-tier SEER 14–16 |
| Full HVAC system replace (AC + furnace) | $6,000 – $12,000+ | Both units, includes labor |
| Heat pump install (whole-home) | $5,500 – $14,000 | Cold-climate models on higher end |
| Ductless mini-split (single zone) | $2,500 – $5,000 | Per zone; multi-zone systems scale up |
| Ductwork repair / replacement | $500 – $4,000 | Depends on access and scope |
What drives costs up
System tonnage (size)
AC + heat-pump systems are sized in "tons" — 1 ton = 12,000 BTU/hr cooling capacity. A typical 2,000 sq ft home needs ~3 tons. Tonnage doubles cost roughly linearly: a 2-ton install runs $3,000–$5,500, a 5-ton install runs $7,000–$12,000+.
Efficiency rating (SEER, AFUE)
AC SEER ratings range from 14 (code minimum in most states) to 26+ (premium variable-speed). Each 2-SEER step typically adds ~$500–$1,500 to install cost. AFUE ratings on furnaces range 80% (standard) to 98% (premium condensing). Premium efficiency pays back in 3–7 years in colder climates, longer in mild ones.
Ductwork condition
Older or poorly-installed ductwork can lose 20–30% of heating/cooling efficiency. Repair runs $500–$2,000; full replacement on a typical home runs $3,000–$10,000. Bad ducts often discovered during install — adds time + cost.
Refrigerant type + transition costs
Older systems use R-22 (phased out, expensive — $50–$150/lb where still available). Current systems use R-410A. New 2025+ systems are transitioning to R-454B or R-32 (lower-GWP refrigerants). Repairs on older systems can hit $1,500+ just for refrigerant.
Emergency / after-hours service
After-hours, weekend, and holiday rates typically run 1.5x–2x standard pricing. Emergency call-out fees alone can run $150–$400 before any work starts. Worth scheduling preventive maintenance in shoulder seasons.
AC repair vs. replace decision
The "$5,000 rule" is a useful starting point: multiply the age of your AC by the repair cost. If the result is more than $5,000, replacement is usually the better call.
A 12-year-old AC needing a $500 repair: 12 × $500 = $6,000 → lean toward replacement. A 5-year-old AC needing a $500 repair: 5 × $500 = $2,500 → repair is fine.
Other replace-signals: refrigerant is R-22 (recharge costs are punishing), efficiency is well below current code, or the system has needed multiple repairs in the last 2 years. Energy bills creeping up year-over-year on the same usage pattern is often the leading indicator.
Hidden costs in HVAC quotes
Reputable HVAC contractors itemize these — anything missing usually surfaces as a change order after work starts:
- Manual J load calculation (proper sizing — non-negotiable for installs)
- Permits + inspection fees ($150–$500 typical)
- Old-system removal + refrigerant recovery ($150–$400)
- Thermostat upgrade (smart thermostats run $200–$400 installed)
- Condensate-drain + line repairs
- Electrical upgrades (some installs need a new dedicated circuit)
- Pad / mounting for outdoor unit
- Warranty registration (often requires installer to register within 60 days)
How to save money
Schedule annual tune-ups in shoulder seasons
Spring (March–April) for AC, fall (September–October) for heating. Tune-ups catch problems before they become emergency repairs, extend system life, and shoulder-season pricing is 10–20% lower than peak.
Check manufacturer + utility rebates
Carrier, Trane, Lennox, and other major brands run installer-tied rebates ($500–$2,000) on premium systems. Local utility companies often offer additional efficiency rebates ($200–$1,500). Federal Inflation Reduction Act tax credits add up to $2,000 on heat pumps.
Get 3+ quotes for installs
New-system quotes vary 25–35% on the same job. Three quotes is the minimum. Make sure each quote uses the SAME Manual J load calculation — if quotes use different sizing, you're comparing different systems.
Replace before failure
Planning a replacement when your old system is 10–12 years old (vs reactive replacement after a summer breakdown) saves $1,000–$2,500 in install pricing plus 1–7 days of no AC. Pros have more time + don't need to expedite.
Regional cost variation
National-average pricing varies by region. Here's how to adjust your expectations based on where you live:
| Region | Typical adjustment |
|---|---|
| Northeast / Midwest (cold climates) | +10–20% — premium heat-pump or high-AFUE furnace requirements |
| South + Southwest (hot climates) | On par — high demand but competitive contractor market |
| West Coast (CA, OR, WA) | +15–25% — high labor + Title 24 (CA) efficiency requirements |
| Mountain West | +5–15% — altitude derating + variable climate needs |
Common cost questions
How long does HVAC installation take?
A simple AC + furnace swap on existing ductwork: 1 day. A more complex install requiring electrical upgrades, new ductwork, or relocation: 2–5 days. Heat-pump retrofits typically take 1–2 days. Whole-home ductless mini-splits (multi-zone): 2–4 days.
How often should I service my HVAC system?
Twice a year — AC tune-up in spring before cooling season, heating tune-up in fall before heating season. Maintenance plans run $150–$400/year and often include both visits plus priority emergency service.
Should I get a heat pump instead of a furnace + AC?
Often yes — especially in moderate climates (zones 3–5). Heat pumps provide both heating + cooling from one system, are 2–4x more efficient than electric resistance heat, and qualify for federal tax credits. Cold-climate heat pumps (with auxiliary backup heat) now work down to -15°F. Trade-off: higher upfront cost ($5,500–$14,000 vs $6,000–$10,000 for furnace + AC).
What size HVAC system do I need?
Sizing depends on square footage, insulation, window area, ceiling height, sun exposure, and climate zone. A proper Manual J load calculation is required for accurate sizing. Rule-of-thumb: ~1 ton of AC per 500–600 sq ft in moderate climates. Oversized systems cycle on and off (bad for efficiency + humidity), undersized systems run constantly (bad for longevity + comfort).
How much can I save with a high-SEER AC?
Going from SEER 14 to SEER 18 saves roughly 22% on cooling-related electricity. On a $200/month summer bill, that's ~$44/month or $200–$300/year. Premium SEER 22+ systems save 35%+ vs code minimum. Payback periods: 5–8 years in hot climates, 10–15 years in mild climates.
Why is my AC running but not cooling?
Most common causes: dirty air filter (clogged airflow), frozen evaporator coil (often from low refrigerant or restricted return), capacitor failure (cheap repair, ~$150–$300), compressor failure (expensive, $1,000–$2,500), thermostat issue. A tech can usually diagnose + fix most issues in a single visit.
Are HVAC techs licensed?
All HVAC techs need EPA 608 certification to handle refrigerant. Most states require a state HVAC contractor license. Verify both before any work — especially for installs. Look for NATE certification (industry-standard technician credential) as a quality signal.
