An ERV system cost typically ranges from $1,000 to $8,500 depending on unit size, ductwork, and installation complexity. How much does an ERV system cost depends on capacity (CFM), whether existing ducts are usable, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete ERV Install (Single-family) | $1,000 | $3,500 | $8,500 | Assumptions: 800-2,400 CFM range, normal access, suburban region. |
| ERV Unit Only | $400 | $1,200 | $3,200 | Per unit price varies by CFM and heat-exchange core. |
| New Ductwork / Modifications | $600 | $2,000 | $6,000 | Includes materials and labor to add or rebuild ducts. |
| Controls and Balancing | $150 | $650 | $1,800 | Thermostat integration, VFDs, and airflow balancing. |
Typical ERV System Prices For A Single-Family Home
Most homeowners pay $1,800-$5,000 for a typical ERV install including a mid-range unit and minor duct connections.
Price assumptions: 800-1,500 CFM unit for a 1,200-2,500 sq ft house, existing ductwork in good condition, standard wall or attic install. Total low: $1,000 (DIY or basic unit, minimal labor). Average: $3,500 (professional install, 1,000 CFM, modest duct taps). High: $8,500 (large-capacity unit, extensive duct rework, premium controls).
Assumptions: Midwest labor rates, standard materials, normal access.
Materials, Labor, Equipment, Permits, Delivery/Disposal, and Overhead In Quotes
Breakdown of a contractor quote usually shows materials, labor, equipment, permits, delivery/disposal, and overhead as the main line items.
| Line Item | Low | Average | High | Typical Notes |
|---|---|---|---|---|
| Materials (unit, core, filters) | $400 | $1,100 | $3,000 | Unit price varies by CFM and core type. |
| Labor (install & connections) | $300 | $1,200 | $3,000 | 4-20 hours at $75-$125 per hour. |
| Equipment (lifts, scaffolding) | $0 | $150 | $700 | Rental added for difficult attic/roof access. |
| Permits & Inspections | $0 | $75 | $400 | Municipal fees vary widely. |
| Delivery/Disposal | $50 | $150 | $600 | Old unit removal and disposal fees. |
| Overhead / Profit | $200 | $600 | $2,000 | Usually 10-30% of job subtotal. |
How CFM, Duct Condition, And Core Type Change ERV Quotes
Capacity and duct condition are the two largest technical variables—upgrading from 800 CFM to 2,000 CFM can double or triple unit and labor costs.
Example thresholds that change price: under 1,000 CFM (small home) = lower-cost units $400-$1,200; 1,000-1,500 CFM (typical family home) = $1,000-$2,000; over 1,500 CFM (large homes or multi-zone) = $2,000-$5,000. Ductwork: usable duct taps add $200-$800; full duct replacement adds $1,000-$6,000. Core type: enthalpy cores (moisture transfer) cost more than simple sensible cores by $200-$800.
How To Lower ERV Installation Price Without Sacrificing Performance
Control scope: choose a unit sized to your actual conditioned volume, reuse existing ducts when possible, and schedule installs in shoulder seasons for lower labor rates.
Specific savings tactics: accept a mid-range core instead of premium enthalpy if humidity control is not critical (-$200 to -$800), consolidate installs with HVAC service to avoid duplicate mobilization (-$150 to -$600), and prepare attic access or clear crawl spaces to reduce labor hours (-$100 to -$500).
Regional Price Differences For ERV Systems Across The U.S.
Expect 10-30% higher total installed cost in high-cost urban areas (Northeast, West Coast) and 10-20% lower in rural Midwest and South.
| Region | Low | Average | High |
|---|---|---|---|
| Northeast / Urban | $1,200 | $4,200 | $9,000 |
| Midwest / Suburban | $1,000 | $3,200 | $7,000 |
| South / Rural | $900 | $2,800 | $6,500 |
| West Coast / Metro | $1,300 | $4,600 | $9,500 |
Typical Labor Time, Crew Size, And Scheduling For An ERV Job
Installation often requires a 1-2 person crew for 4-20 hours depending on ductwork, with an average job taking 8-12 hours.
Small swap (unit only, accessible): 2 people × 4-6 hours. Moderate install (tapping ducts, short runs): 2 people × 8-12 hours. Extensive install (new trunk lines, roof/attic work): 3 people × 12-20 hours. Hourly rates commonly range $75-$125 per hour.

Concrete examples help match expectations to typical homes and scopes.
| Scenario | Specs | Labor Hours | Total Price |
|---|---|---|---|
| Budget Replace | 800 CFM unit, existing ducts usable, attic mount | 4 hours | $1,000-$1,400 |
| Standard Install | 1,200 CFM, 2 duct taps, balancing, thermostat tie-in | 8-10 hours | $2,800-$4,200 |
| Full Upgrade | 1,800 CFM, new trunkwork, enthalpy core, controls | 16-20 hours | $6,000-$9,000 |
