The Greenheck SP-B110 price varies by whether buyers buy the fan only or pay for professional installation, controls, and roof curb work; typical total pricing depends on CFM, motor type, and mounting. This article shows what buyers usually pay for a Greenheck SP-B110, with low-average-high ranges and the main cost drivers for U.S. projects.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Unit Only (new) | $400 | $650 | $1,100 | Assumptions: base model, single-speed, domestic distributor. |
| Installed (residential roof/bath) | $900 | $1,650 | $3,200 | Assumptions: 50-150 CFM, 2-4 hours labor, simple curb or wall. |
| Commercial Install (rooftop curb) | $1,800 | $3,900 | $7,500 | Assumptions: crane, curb modification, permits. |
| Controls & Accessories | $75 | $250 | $1,200 | Includes timers, VFD, roof curb, dampers. |
Typical Total Price for a Greenheck SP-B110 Unit and Standard Install
Expect a retail unit price of $400-$1,100 and an installed residential price of $900-$3,200 depending on complexity.
Unit-only: $400-$1,100. Installed residential job (bath/kitchen exhaust): $900-$1,900 for straightforward wall or roof mounting, supplies, and 2-4 hours of labor. Higher-end residential with insulated curb, VFD, or controls: $1,900-$3,200.
Assumptions: Midwest labor rates, standard 80-150 CFM application, standard single-phase motor, normal roof access.
Line-Item Costs: Materials, Labor, Equipment, and Permits
Breakdown of a typical quote shows materials, labor, equipment, delivery/disposal, and permits as the main line items affecting final price.
| Materials | Labor | Equipment | Delivery/Disposal | Permits |
|---|---|---|---|---|
| $400-$1,200 (fan, curb, duct, dampers) | $300-$1,200 (2-12 hours × $75-$125/hour) | $0-$1,500 (crane rental or lift) | $50-$300 (old unit disposal, packaging) | $0-$500 (local mechanical permit) |
How CFM Rating, Motor Type, and Controls Change the Price
CFM, motor efficiency (EC vs PSC), and whether a VFD or timed control is included move pricing by hundreds to thousands of dollars.
CFM: base SP-B110 installs commonly serve 50-150 CFM. Under 150 CFM: add $0-$200. Above 150 CFM or special high-static applications: add $300-$900. Motor: PSC single-phase is cheapest; EC/ECM motors add $150-$600. VFD or smart control: $250-$1,200.
Thresholds: >150 CFM, >1.5″ w.g. static pressure, or three-phase power typically push the quote into the high range.
Site Conditions That Drive Up the Final Quote
Roof access, curb modification, long duct runs, and seismic or code upgrades are common site conditions that raise costs significantly.
Roof access: ground-level or attic access adds $0-$200; crane or boom: $600-$1,500. Curb modification or new curb: $250-$1,100. Long horizontal duct runs over 20 ft: add $150-$800. Code upgrades (rooftop guards, fire damper): $200-$1,200.
Example thresholds: crane required when roof height >25 ft or when rooftop unit weight/size prevents safe lift.
Practical Ways To Reduce the SP-B110 Price When Budgeting
Controlling scope, choosing a simpler motor and controls, and prepping the site reduce the installed cost without unnecessary upgrades.
Buy unit only and use a local HVAC pro for installation to avoid dealer markup. Choose PSC motor over EC if initial budget is tight (expect higher operating costs). Consolidate with other HVAC work to reduce mobilization fees. Prepare access: clear roof paths and pre-measure curb to avoid same-day extras.
Regional Price Differences and What To Expect Across the U.S.
Prices vary: expect 10%-35% higher installed costs in high-cost coastal metro areas versus lower Midwest and South regions.
Estimate deltas: Midwest baseline; Northeast/West Coast: +15%-35%; Southeast/Deep South: -5% to +10% depending on city. Labor rates example: $75-$95/hour Midwest; $95-$150/hour coastal metros.
Three Real-World Quote Examples With Specs and Totals
Concrete quote examples help translate ranges into realistic budgets for common scenarios.
| Scenario | Specs | Labor Hours | Per-Unit Pricing | Total |
|---|---|---|---|---|
| Basic Bathroom Replace | SP-B110, PSC motor, existing curb | 2 hours | Unit $500, Labor $150 | $900-$1,100 |
| Residential Roof with New Curb | SP-B110, EC motor, new insulated curb, short duct | 4-6 hours | Unit $750, Curb $450, Labor $600 | $1,800-$2,300 |
| Commercial Rooftop Upgrade | SP-B110 high-static, VFD, crane, permit | 8-12 hours | Unit $1,050, Crane $1,200, Labor $1,200 | $3,500-$7,500 |
Typical Installation Time, Crew Size, and Hourly Rates
Installation time and crew size commonly determine field labor cost more than small material differences.
Residential swap: 1-2 technicians, 2-6 hours. Small commercial: 2-3 techs, 6-12 hours. Hourly rates: $75-$125/hour typical; specialty rigs or union crews may be $125-$200/hour. Allow for a minimum charge of 2-4 hours on most service calls.
