Vertical ground source heat pump cost varies widely by bore depth, loop material, and labor access; most homeowners pay between $15,000 and $45,000 for a complete closed-loop vertical GSHP install. This article gives realistic low-average-high pricing, per-ton and per-foot ranges, and the main factors that drive the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete 2–4 ton system | $15,000 | $28,000 | $45,000 | Assumptions: 2–4 ton, 250–400 ft total bore, standard soil, suburban site. |
| Per ton installed | $4,000 per ton | $7,000 per ton | $11,000 per ton | Includes heat pump, ground loop, basic ducting/controls. |
| Per vertical bore | $2,000 per bore | $3,500 per bore | $6,000 per bore | Assumes 150–400 ft per bore, contractor driller rates vary. |
Typical Installed Price For A Vertical Closed-Loop System
Most U.S. homeowners pay $15,000-$45,000 for a vertical closed-loop ground source heat pump installed.
That range assumes a 2–4 ton heat pump for a 1,200–2,500 sq ft home, 250–400 ft of bore depth total, standard-grade loop piping, and average regional labor. Per-ton pricing is $4,000-$11,000; per-foot loop drilling costs are typically $4-$15 per ft for drilling plus $1-$3 per ft for grout and pipe.
Assumptions: Midwest labor rates, standard materials, normal access.
Breakdown Of Major Quote Components And Typical Shares
Expect materials, drilling, and labor to make up the bulk of the invoice—equipment plus ground work account for 70%-90% of the total.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $3,000-$12,000 (heat pump, loops) | $4,000-$15,000 () | $2,000-$10,000 (drilling rig mobilization) | $200-$1,200 | $200-$1,500 |
Typical component roles: heat pump unit and controls (materials), drilling rig and crew (equipment + labor), trenching or site prep (labor), bore grout/pipe (materials), permits and hookup (permits).
How Bore Depth, Tons, And Number Of Bores Change The Quote
Bore depth, system tonnage, and number of bores are the strongest price drivers—each extra 100 ft per bore often adds $400-$1,500.
Numeric thresholds: switching from 2 to 3 tons increases total cost roughly $5,000-$9,000; each additional bore (150–400 ft) typically costs $2,000-$6,000 depending on depth and drilling difficulty. Systems over 5 tons frequently require heavier equipment and higher permit fees that add $3,000+.
Practical Ways To Reduce Vertical GSHP Price On A Budget
Control scope by choosing a lower-tonnage unit, reducing bore depth per ton with supplemental air-source backup, or bundling loop drilling across neighboring projects.
Other cost-saving moves: provide good site access to avoid rig mobilization fees, accept factory-standard controls instead of premium smart thermostats, and schedule work in shoulder seasons when drilling crews have more availability. Compare at least three bids with detailed line items.
Regional Price Differences And What To Expect In Each Market
Coastal urban areas and the Northeast commonly run 10%-35% above the national average; rural Midwest and parts of the South often run 5%-20% below average.
Example deltas: Northeast +20%-35% (higher labor and permit costs), Mountain West +5%-25% (rock drilling premiums), Southeast -5%-15% (lower labor but longer mobilization if specialists are scarce). Adjust your budget upward for remote sites or constrained access.
Extra Charges, Add‑Ons, And Typical Time On Site
Allow for $500-$3,000 in extra fees for unexpected bedrock, casings, grout additives, or utility re-routing.
Typical job duration: 2–6 days for drilling and loop installation, plus 1–3 days for equipment hookup and commissioning; total crew time often 20–80 hours depending on system size. Common add-ons: soil testing $200-$800, grout additives $150-$900, rock hammering surcharge $1,000-$5,000.
Real-World Quote Examples With Specs And Totals
Comparing three realistic examples helps translate ranges into budgets homeowners can use when asking for quotes.
| Example | Specs | Labor/Hours | Per-unit Rates | Total |
|---|---|---|---|---|
| Small | 2 ton, 2 bores × 150 ft | 30 hours | $4,000/ton; $2,200 per bore | $15,000-$17,500 |
| Average | 3.5 ton, 3 bores × 250 ft | 60 hours | $7,000/ton; $3,500 per bore | $28,000-$32,000 |
| Large | 5 ton, 4 bores × 350 ft | 80+ hours | $9,500/ton; $5,000 per bore | $40,000-$60,000 |
Use these examples when requesting line-item quotes: ask for per-ton equipment price, per-bore drilling rate, grout and pipe cost, and mobilization fees so bids are comparable.
