Ductwork Installation & Repair Costs
Duct condition is one of the biggest variables in HVAC pricing nationally — poor ducts waste 20–30% of cooling energy.

|---|---|---|
| New duct installation | $2,800 – $6,500 | Full home, insulated flex or sheet metal |
| Duct replacement (partial) | $1,200 – $3,500 | Attic or crawlspace sections |
| Duct sealing (Aeroseal / mastic) | $450 – $1,200 | Recommended for homes built before 2005 |
| Duct cleaning | $350 – $700 | Not a substitute for damaged ducts |
Energy Efficiency, SEER Ratings & Rebates
Higher SEER ratings cost more upfront but cut summer electric bills — critical in warm climates where AC runs much of the year.
SEER ratings explained
- 14 SEER (standard): Minimum in many states; lowest install cost
- 16 SEER (high): ~12% more efficient than 14 SEER; best value in most U.S. climates
- 18+ SEER (premium): Up to 25% savings vs. 14 SEER; ideal for large homes
Estimated annual savings (2,000 sq ft)
- 14 → 16 SEER: $180 – $280/year off cooling
- 14 → 18 SEER: $320 – $450/year
- Payback on upgrade premium: typically 4–7 years
2026 rebates & tax credits
- Federal tax credit: up to $2,000 for qualifying heat pumps
- Utility rebates (varies by provider): $200 – $1,200 for high-efficiency equipment
- Ask your contractor — many handle rebate paperwork
HVAC Repair vs. Replacement
Know when a repair makes sense and when a new system saves money on energy and breakdowns.
HVAC repair
$150 – $800
per service call (parts extra)
- System under 10 years old with a single failed component
- Repair cost under 30% of replacement price
- Refrigerant leak, capacitor, thermostat, or blower issues
- Still meeting cooling/heating demand efficiently
Repair when: the unit is young and the fix is under $1,500.
Full replacement
$4,500 – $18,000
typical national range
- Unit is 12–15+ years old (AC) or 15–20+ (furnace)
- R-22 refrigerant system — expensive to recharge
- Rising energy bills or uneven cooling rooms
- Repairs exceed $3,000 or happen twice in 12 months
Replace when: repair quote exceeds 50% of a new system or energy bills jumped 25%+.

Climate drives system sizing, efficiency priorities, and long-term operating costs.
Hot & dry climates
- Extreme summer heat — oversizing risks short-cycling and humidity issues
- High cooling load; prioritize SEER and proper duct sealing
- Heat pumps work well in mild climates; reduced heating demand in winter
- Attic installations need extra insulation around ductwork
Florida
- High humidity — variable-speed systems and dehumidification matter
- Coastal corrosion requires coated coils and regular maintenance
- Mold prevention depends on proper duct insulation
Arizona
- Extreme dry heat — very high cooling load per sq ft
- Solar + high-SEER AC pairs well for peak summer bills
- Minimal heating needs; heat pumps still viable
HVAC Permits & Inspections
Nearly all municipalities require a permit for HVAC installation. Permit fees typically run $150–$500 for residential work, and your licensed contractor usually pulls the permit.
- Mechanical permit: $150–$350 for residential HVAC change-out
- Inspection: Rough-in and final — usually included in permit fee
- Timeline: Same-day to 3 business days for online filing
- Contractor responsibility: Licensed HVAC pros pull permits on your behalf
| City | Permit cost | Requirement |
|---|---|---|
| Dallas, TX | $150 – $450 | Mechanical permit + inspection |
| Houston, TX | $150 – $400 | Varies by district |
| Phoenix, AZ | $125 – $350 | Same-day in many cases |
| Miami, FL | $175 – $500 | Wind code may apply |
| Los Angeles, CA | $300 – $650 | Title 24 compliance |
| Chicago, IL | $200 – $450 | Winter scheduling |

Durham, NC — Local Cost Context
Prices on this page adjust for Durham-area labor, permits, and climate — not a generic national template.
Labor
Durham blends older in-town housing near Duke and RTP with suburban growth in Chapel Hill direction. Contractors experienced with older home quirks — cast iron plumbing, small kitchens — are in steady demand.
Contractor labor runs about 9% below the U.S. average; typical permit fees in our model start around $225 for standard residential work.
Permits
City of Durham Neighborhood Improvement Services issues permits. Durham County handles unincorporated areas. Historic districts near downtown may require design review.
Climate
Durham shares Triangle humidity with older housing challenges:
- Humid summers — older homes often lack modern insulation
- Aging roofs on 1960s–1980s stock due for replacement
- Crawl-space moisture in pre-1970 homes
Top local projects
- Bath remodel with plumbing upgrade — Cast iron replacement common in older Durham homes
- Roof replacement — Aging shingle stock in established neighborhoods
- Mini-split or heat-pump HVAC — Older homes without ductwork
HVAC Installation FAQs
Answers optimized for voice search, AI overviews, and People Also Ask.
How much does HVAC installation cost?
HVAC installation typically costs $4,500–$18,000 nationally for a typical 2,000 sq ft home. Most homeowners pay around $8,200 for central AC at 16 SEER, depending on ductwork and efficiency. Use our calculator for a personalized range.
Does HVAC replacement include ductwork?
Most quotes assume existing ductwork in good condition. New duct installation adds $2,800–$6,500. Always inspect ducts for leaks — sealing costs far less than full replacement.
What size HVAC system do I need?
A typical 2,000 sq ft home usually needs a 3.5–4 ton unit, but Manual J load calculation is the only accurate method. Oversized systems short-cycle; undersized units run constantly during peak summer heat.
Is a heat pump cheaper than AC?
Heat pumps cost 10–20% more than AC-only but replace both furnace and air conditioner. In many regions, a heat pump often wins on total equipment cost versus separate systems.
How long does HVAC installation take?
Standard replacements take 1–2 days. New ductwork or multi-zone mini-splits take 3–5 days. Permit approval in most cities may add 1–3 business days before work starts.
What SEER rating should I choose?
16 SEER is the sweet spot for most U.S. homes — meaningful savings over 14 SEER without the premium of 18+. High-usage homes benefit most from 18+ SEER and utility rebates.
