New Furnace and Air Conditioner Cost Guide 2026

When budgeting for a new furnace and air conditioner, buyers typically see a wide range driven by system size, efficiency, and installation complexities. The cost landscape includes equipment price, labor, permits, and potential add-ons. This guide provides practical pricing in USD, with clear low–average–high ranges and per-unit portions where relevant.

Item	Low	Average	High	Notes
System (Furnace + AC) — Unit Only	$2,800	$4,600	$7,500	Gas or electric furnace + central AC; excludes installation
Installation Labor	$1,200	$2,900	$5,000	Labor hours vary by home layout
Permits & Inspections	$100	$400	$1,000	Local requirements vary by city
Delivery/Disposal	$50	$200	$600	Old equipment haul-away often optional
Optional Accessories	$0	$300	$1,200	Smart thermostat, air cleaners, or UV sterilizers
Warranty & Contingency	$100	$400	$1,000	Extended coverage and unforeseen issues

Assumptions: region, specs, labor hours.

Overview Of Costs

Typical cost ranges reflect equipment quality, efficiency, and local labor markets. For a mid-range setup (gas furnace with 14–16 SEER AC), total installed price commonly runs from about $6,000 to $10,000. Higher-efficiency systems (16–20 SEER or variable-speed units) or in homes with difficult ductwork can push totals to $10,000–$15,000 or more.

Pricing is often presented as totals plus per-unit figures when a unit’s efficiency tier is specified. A common rule: per-ton cooling capacity adds roughly $1,000–$2,000 for equipment, while high-efficiency components and smart thermostats contribute to the delta. Budgeters should expect both upfront costs and potential seasonal adjustments.

Cost Breakdown

Category	Materials	Labor	Equipment	Permits	Delivery/Disposal	Warranty
Subtotal	$2,400–$3,700	$1,200–$2,900	$2,800–$4,600	$100–$1,000	$50–$600	$100–$1,000

Assumptions: SEER-rated equipment, standard ductwork, and no major structural changes.

Price Components

The largest drivers are equipment efficiency (SEER and furnace AFUE), system size (tons), and installation complexity. HVAC installers commonly quote: lower ranges for basic one-stage gas furnace with 13–14 SEER AC, and higher ranges for two-stage or modulating equipment with 18–20 SEER. A sizable share of cost variation comes from ductwork needs, refrigerant lines, and electrical upgrades.

Factors That Affect Price

System efficiency (AFUE and SEER) and tonnage have direct cost implications. A 2-ton system costs less than a 4-ton system, but the per-ton price can rise with higher efficiency. ductwork changes or zone controls further influence total costs, as does the choice of smart thermostats and air quality accessories. Regional labor markets also shift pricing by ±10–20% compared to national averages.

Regional Price Differences

Prices vary by region due to labor rates, code requirements, and permit costs. In the Northeast, expect higher installation complexity and elevated permitting, while the South may see lower winter demand but different refrigerant needs. In rural areas, labor may be cheaper, but travel charges and equipment availability can affect overall cost by ±5–15% compared with urban centers.

Labor, Hours & Rates

Typical installation takes 1–2 days, depending on ductwork and old equipment removal. Labor rates commonly range from $75 to $150 per hour, with more complex projects approaching $180 per hour. Estimating a project at 16–24 hours is common for standard replacements, but homes with unusual layouts or multi-zone systems can exceed this range.

Additional & Hidden Costs

Hidden costs may include refrigerant recharge, sealing leaks, or rebalancing ductwork. Replacement of old gas lines or electrical upgrades can add $300–$1,000. Expect occasional add-ons that aren’t included in base quotes, such as carbon monoxide detectors or air purification modules.

Real-World Pricing Examples

Three scenario cards illustrate typical outcomes. Assumptions: single-family home, standard ductwork, city permit where applicable.

Maintenance & Ownership Costs

Ongoing costs include annual maintenance, minor repairs, and filter changes. A typical maintenance visit costs $140–$250 and can extend equipment life. Over a 5-year horizon, plan for $600–$1,200 in routine servicing and potential part replacements.

Assumptions: regional labor market stability, standard warranty terms, typical home size.
