Buyers replacing both furnace and central air typically pay between $5,500 and $12,500 for a new heating and cooling system; final price depends on system size, efficiency, ductwork, and installation complexity. This article focuses on cost estimates and pricing drivers for a new heating and cooling system so readers can plan a realistic budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full HVAC System (installed) | $3,500 | $8,000 | $20,000 | Ranges by home size, SEER/AFUE, and ductwork work |
| Air Conditioner Only (installed) | $2,500 | $5,000 | $12,000 | Split systems, 1.5–5 tons |
| Furnace Only (installed) | $1,800 | $3,500 | $7,500 | Gas, electric, or heat pump options |
| Ductwork Replacement | $2,000 | $5,500 | $12,000 | Depends on linear feet and accessibility |
Total Price For A New HVAC System In A Single-Family Home
Assumptions: 2,000 sq ft, suburban installer, standard access. Typical all-in replacement for furnace plus central AC is $5,500-$12,500 with an average near $8,000; premium high-efficiency systems with extensive ductwork can reach $15,000-$20,000. The most common average for U.S. buyers replacing both units is about $7,500–$9,000 including basic thermostat and permits.
How Materials, Labor, Equipment, and Permits Break Down
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $1,500-$6,000 | $1,500-$4,500 | $1,500-$8,000 | $100-$600 | $150-$800 |
Assumptions: Midwest labor rates, standard manufacturer equipment, normal access. Materials and equipment typically make up 50%–75% of the installed price, with labor and disposal the remainder.
How System Size (Tonnage) and SEER/AFUE Ratings Affect Price
AC tonnage: 1.5–2.5 tons fits most 1,000–1,500 sq ft homes while 3–5 tons fit 2,000–3,500 sq ft homes; expect $2,500-$4,000 for 2-ton units and $4,500-$8,000 for 4-ton units. Efficiency: 13–16 SEER is common ($3,000-$5,500 installed), 17–20 SEER costs 10%–35% more, and 21+ SEER is premium and can add $2,000-$5,000. Choosing a larger tonnage or higher SEER rating raises equipment cost nonlinearly and may require larger ductwork or electrical upgrades.
Site Conditions That Drive Major Price Changes
Hard-to-access installations, multistory homes, long refrigerant lines (>50 ft), or electrical service upgrades add cost: add $300-$1,200 for tight access, $700-$2,500 for extended refrigerant runs, and $1,500-$4,000 for a service panel upgrade. Big-ticket site conditions (panel upgrade, significant roof or foundation work) can increase the project by 20%–60%.
Practical Ways To Lower Your Heating And Cooling System Price
Keep the original duct layout when possible, opt for mid-efficiency rather than top-tier SEER, schedule during shoulder seasons, and get at least three written quotes. Simple scope choices—like repairing duct leaks instead of full replacement—often save $1,000-$4,000.
Regional Price Differences And What To Expect By Market
Assumptions: national averages, urban vs rural effects. Expect prices ~10%–25% higher in coastal metro areas (Northeast, West Coast) and ~5%–15% lower in parts of the Midwest and South. Contractor availability and local labor rates usually explain regional deltas more than equipment MSRP.
Common Add-Ons, Removal Fees, and Typical Job Duration
| Item | Low | Average | High |
|---|---|---|---|
| Old Unit Removal | $75 | $200 | $600 |
| Thermostat (smart) | $75 | $200 | $600 |
| Duct Sealing/Minor Repair | $250 | $900 | $2,500 |
| Typical Job Duration | 6 hours | 1-2 days | 3-5 days |
Labor crew size and duration: small jobs use 2–3 technicians; complex replacements can require 3–6 crew members and multiple days. Budget for add-ons and disposal—these often add $200-$2,500 to the base quote.
Three Real-World Quote Examples Buyers See
Example A: 1,400 sq ft ranch, 2-ton 14 SEER AC + 80% AFUE gas furnace, reuse ducts: $4,200-$5,500 (6–10 hours). Example B: 2,400 sq ft two-story, 3.5-ton 16 SEER + 95% AFUE furnace + partial duct replace: $9,000-$12,500 (2–3 days). Example C: High-efficiency 20 SEER heat pump retrofit for 1,800 sq ft, electrical upgrade required: $12,000-$18,000 (3–4 days). These examples reflect common permutations of size, efficiency, and ductwork scope that determine final quotes.
