Contractor voices attached to the specs.
The table below compares Bore's documented performance across residential, light commercial, and institutional project types. Contractor testimonials are embedded beneath each parameter row — the numbers and the witnesses agree.
| Parameter | Residential Single-family · <5 tons | Light Commercial Office / Retail · 5–40 tons | Institutional Schools / Municipal · 40+ tons |
|---|---|---|---|
Typical Loop Field Size Vertical bore, 200 ft depth | 2–4 bores · 400–800 lin ft | 6–16 bores · 1,200–3,200 lin ft | 24–80 bores · 4,800–16,000 lin ft |
"Bore laid out our loop field in a 0.4-acre lot we thought was too tight. They hit 210 ft on every bore and we had the school's mechanical room commissioned six weeks ahead of schedule." Marcus Reinholt Principal, MEP Reinholt Engineering Group · Columbus, OH Jefferson K-8 · 44-ton system · 2024 | |||
System Capacity Tons (12,000 BTU/ton) | 2–5 tons | 10–40 tons | 50–400 tons |
COP Range · Heating Mode Coefficient of Performance | 3.8 – 4.9× | 4.2 – 5.1× | 4.5 – 5.6× |
"Our mechanical engineer spec'd a 4.5 COP floor for the LEED submittal. Bore's loop field hit 4.9 in the first heating season — that's the number that got us EA Credit 1." Sandra Okafor LEED AP BD+C · Project Engineer Meridian MEP · Philadelphia, PA Northside Community Center · 28-ton · 2023 | |||
SEER Equivalent Cooling mode comparison | 18 – 22 SEER | 22 – 26 SEER | 26 – 34 SEER |
IRA §48 Tax Credit Eligible Inflation Reduction Act 2022 | 30% of system cost | 30% of system cost | 30% + bonus adders up to 50% |
"The 30% ITC closed the budget gap on three school projects in one fiscal year. Bore's documentation package was exactly what our CPA needed — no back-and-forth." Derek Vasquez Director of Facilities Lakeshore Unified School District · Chicago, IL 3 campuses · 180 tons aggregate · 2024–2025 | |||
Avg Simple Payback Period Post-incentive, vs. gas/electric | 6–9 years | 5–7 years | 4–6 years |
Drilling Footprint Required Surface area during install | 15×15 ft per bore | 12×12 ft per bore | 10×10 ft per bore |
"We were white-labeling Bore for a customer with a finished backyard. Their crew drilled four bores in two days, re-seeded the cores, and you couldn't tell they'd been there." Tony Ferraro Owner Ferraro Mechanical · Hartford, CT Residential retrofit · 4-ton · 2023 | |||
Bore Depth Range Subsurface installation | 150–300 ft | 200–400 ft | 200–500 ft |
HDPE Pipe Warranty Factory-fused loop piping | 50 years | 50 years | 50 years |
Mobilization Lead Time PO to on-site (partner SLA) | 10–14 days | 14–21 days | 21–45 days |
"Bore was on my bid sheet two days after I called. They had insurance certs and a license number I could put in the proposal before the GC deadline. That's what won us the job." Jennifer Kwon VP Estimating Kwon Mechanical Contractors · Pittsburgh, PA Net-zero office campus · 90-ton · 2025 | |||

"I needed a full loop-field thermal conductivity report, grouting logs, and ASHRAE 90.1 compliance docs for a LEED Gold submittal. Bore had the folder ready before I finished the specs." Priya Nambiar Principal Mechanical Engineer Nambiar + Hollis Engineers · Boston, MA Mixed-use LEED Gold · 55-ton · 2024 | |||
