Buyers typically pay between $1,200 and $8,500 for an air-to-air heat recovery or energy recovery exchanger, depending on capacity, installation complexity, and model. This article focuses on air to air exchanger cost and breaks down typical totals, per-unit rates, and the major variables that change a final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Unit Only | $600 | $1,200-$2,500 | $5,000 | Small HRV/ERV units for single-family homes |
| Installed (12-20 SEER equivalent) | $1,200 | $2,500-$4,500 | $8,500 | Includes labor, basic duct tie-in |
| Per sq ft Ventilation Impact | $0.10 | $0.25-$0.75 | $1.50 | Cost per conditioned sq ft for whole-house systems |
| Commercial / Large Homes | $4,000 | $8,000-$15,000 | $35,000 | Large-capacity ERV with controls |
Typical Installed Price For A Single-Family Home
Most U.S. households pay $2,500-$4,500 for a midrange air-to-air exchanger fully installed.
Assumptions: 1,800-2,500 sq ft home, standard duct access, 150–300 CFM unit sizing, basic controls. Low-end ($1,200-$1,800) covers retrofit with small HRV/ERV and minimal duct work. High-end ($5,000-$8,500) includes high-efficiency ERV, new duct runs, condenser-style housings, and smart control integration.
Assumptions: Midwest labor rates, standard materials, normal access.
Cost Breakdown: Materials, Labor, Equipment, Delivery
Expect the quote to divide into materials, labor, equipment rental, and delivery/disposal fees.
| Materials | Labor | Equipment | Delivery/Disposal |
|---|---|---|---|
| $600-$4,000 (unit, filters, controls) | $600-$2,500 (2-12 hours × $75-$125/hr) | $0-$300 (scaffolding, lifts) | $50-$400 (old unit removal, disposal) |
How Capacity, CFM, and Efficiency Alter The Quote
Unit capacity and airflow are the clearest price levers: under 150 CFM units run $600-$1,200; 150-500 CFM units typically cost $1,200-$4,000; above 500 CFM jumps into $4,000+ territory.
Two niche drivers: 1) Heat recovery core type—enthalpy cores (humidity transfer) add $300-$900 vs. sensible cores. 2) Ventilation rate—each additional 100 CFM usually adds $200-$600 in unit cost and $100-$300 in labor if ducts expand.
Practical Ways To Lower Your Air-to-Air Exchanger Price
Control scope: choose a unit sized for measured ventilation needs, reuse existing ducts, and install during off-peak seasons to reduce the quote.
Specific tactics: accept a basic control rather than integrated smart thermostats ($200-$600 saved), schedule work in late fall/early spring (contractors offer lower rates), and combine with other HVAC jobs to avoid separate mobilization fees ($150-$400 saved).
How Regional Differences Affect Final Costs
Urban and coastal areas typically add 10%-30% to the national average due to higher labor and permit costs; rural markets can be 5%-15% below average.
Example deltas: Northeast/West Coast +15%-30%; Midwest/South +0%-10%; Rural/Suburban -5%-15%. Permit and inspection fees range from $25 to $400 depending on municipality.
Common Add-Ons, Prep Work, And Hidden Fees To Budget For
Plan for add-ons: new duct sections ($4-$9 per sq ft), wall cores for through-wall vents ($150-$600 per opening), and balancing / commissioning ($150-$600).
Other fees: electrical hookup if a new circuit is needed ($200-$800), condensate drains ($75-$250), and upgraded filters or MERV-rated accessories ($30-$150). Rush installs can add 10%-25% to labor.
Three Real-World Quote Examples With Specs
Concrete quotes help set expectations for different house sizes and scopes.
| Scenario | Unit/Spec | Labor Hours | Price |
|---|---|---|---|
| Small retrofit | HRV 120 CFM, through-wall | 2-4 hrs | $900-$1,600 |
| Typical single-family | ERV 250 CFM, duct tie-in, commissioning | 6-10 hrs | $2,500-$4,000 |
| Large home / light commercial | ERV 900 CFM, new ducts, controls | 20-60 hrs | $8,000-$18,000 |
Assumptions: pricing reflects combined materials and labor in average U.S. markets; permits not included in all scenarios.
Questions That Change The Quote Quickly
Prepare answers about existing duct condition, desired CFM, and whether humidity transfer is required—these three items typically change the estimate by hundreds to thousands of dollars.
Examples: If ducts need re-lining add $500-$3,000; if required ventilation exceeds 500 CFM add $1,000-$6,000; if code requires electrical upgrades add $200-$1,200.
