Mechanical heat recovery ventilation cost varies widely by system size, ductwork condition, and installation complexity. Buyers typically pay between $1,500 and $8,500 total, with the biggest drivers being capacity (CFM), balanced ventilation features, and retrofit ductwork. The figures below reflect typical U.S. pricing for whole‑house and zoned HRV/ERV installations.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small HRV/ERV Unit (compact) | $400 | $900 | $1,600 | ~50-100 CFM; basic controls |
| Whole‑House Unit + Standard Install | $1,500 | $4,200 | $7,500 | 1,000-2,000 sq ft, existing ducts |
| Full Retrofit with New Ducting | $3,500 | $6,800 | $12,000 | Includes duct runs and penetrations |
| Commercial/High‑capacity Systems | $8,000 | $15,000 | $35,000 | Large homes, multi‑zone, energy recovery |
Mechanical Heat Recovery Ventilation Cost Overview For Typical Homes
A typical total price range for a U.S. home is $1,500-$7,500 depending on unit size and retrofit complexity.
Small homes or apartments with existing ductwork can often install a compact ERV/HRV for $1,500-$3,500 total (unit plus 4-8 hours labor). Average single‑family homes (1,200-2,500 sq ft) commonly pay $3,500-$6,500 for a mid‑capacity system (150-300 CFM) with balanced ventilation and basic controls. High‑end installs with new ductwork, zoning, or energy‑level units reach $7,500-$12,000.
Assumptions: Midwest labor rates, standard materials, normal attic/basement access.
Materials, Labor, Equipment, Permits and Disposal in a Typical Quote
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $400-$2,000 (unit, filters, controls) | $600-$3,000 | $0-$500 (lift, scaffolding) | $50-$400 | $75-$300 |
| Includes core unit, duct connectors, insulation | 10-40 hours, $75-$125 per hour | Rental when tight access | Local building permit fees | Old equipment disposal, duct waste |
Labor and the core unit typically make up the majority of the quote—materials and permits are secondary.
How System Size and Airflow (CFM) Change the Final Price
Price increases roughly by $300-$1,000 when upgrading capacity every 100 CFM above a base 150 CFM unit.
Common sizing thresholds: under 100 CFM (compact rooms/apt), 100-300 CFM (most single‑family homes), 300-800 CFM (large homes or zoned systems). Example pricing: 100 CFM unit $600-$1,200; 250 CFM $1,000-$2,500; 500 CFM $2,500-$6,000. Higher CFM requires larger duct collars, stronger fans, and often more labor to balance airflow.
Assumptions: CFM sizing based on ASHRAE ventilation rates for occupancy and house tightness.
Which Site Conditions and Ductwork Needs Raise Quotes Quickly
Retrofit ductwork or difficult access (historic homes, masonry walls) can add $1,500-$6,000 to the total.
Specific drivers: replacing or extending ducts (+$1,000-$4,000 for 50-300 linear ft), adding sound attenuators or insulated runs (+$200-$900), creating rooftop or exterior penetrations (+$300-$1,000 each). Long runs, deep ceilings, or need for crawlspace remediation increase labor hours and may require subcontracted trades (carpentry, patching).
Assumptions: Typical run lengths and moderate demolition work.
Practical Ways To Reduce Mechanical Heat Recovery Ventilation Price
Control scope: choose a correctly sized single‑zone unit and reuse existing ducts where feasible to save the most.
Other tactics: schedule installation in shoulder seasons for lower labor demand, accept a basic digital control instead of smart home integration, provide clear access (clear attic or basement), bundle with HVAC work for contractor discounts, and get 3+ quotes with itemized bids to spot inflated line items.
Assumptions: homeowner can do minor prep work and coordinate schedules.
How Prices Vary Across U.S. Regions and Climate Zones
Expect 10%-35% regional variation: West Coast and Northeast generally cost more than the Midwest and South.
Typical deltas: Midwest baseline; Northeast +15%-30% (higher labor, code complexity); West Coast +10%-25% (permit and labor); South -5%-10% (lower labor rates, but potential for higher humidity‑rated equipment). Cold‑climate ERVs with defrost features cost $300-$1,200 more than warm‑climate models.
Assumptions: percentage deltas based on labor and permitting differences.
Installation Time, Crew Size, and Hourly Rates To Budget Accurately
Most whole‑house installs take 10-40 hours: plan for a 1‑3 day job with a 2‑3 person crew for average homes.
Labor rate examples: $75-$100 per hour for HVAC techs in many suburban markets, $100-$125 in high‑cost metro areas. Small installs: 4-12 hours, 1-2 techs. Full retrofits with new ducting: 24-80 hours, multiple trades. Use to estimate your local labor portion.
Assumptions: no major structural work or electrical upgrade beyond existing circuits.
Common Add‑Ons, Filters, Controls, and Fees That Affect Final Quotes
Expect add‑ons to add $150-$2,500: MERV13+ filters $40-$150, smart controls $150-$600, heat‑recovery cores or enthalpy wheels $400-$1,800.
Other charges: electrical hookup or new circuit $200-$800, balancing and testing $150-$500, rush or emergency fees 20%-50% surcharge. Warranties or extended service plans add upfront cost but may reduce long‑term maintenance spend.
Assumptions: common add‑ons and local electrician fees.
