Buyers replacing or installing an air-to-air heat recovery ventilator typically pay $1,000-$6,000 total; main cost drivers are unit capacity, installation complexity, and duct modifications. This air to air exchanger cost article gives realistic low-average-high pricing and the variables that change quotes within the U.S.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Unit Only | $400 | $1,200 | $3,500 | Assumptions: residential ERV/HRV 60-200 CFM |
| Typical Installation | $600 | $2,500 | $6,000 | Includes labor, basic ducts, one floor home |
| Commercial / High-Capacity | $2,000 | $6,500 | $18,000 | Assumptions: >500 CFM, rooftop or central mechanical room |
| Duct Modification | $200 | $800 | $3,000 | Depends on linear footage and insulation |
Typical Total Price and Per-Unit Costs for Residential Air-to-Air Exchangers
Most U.S. homeowners pay $1,000-$3,500 for a complete residential air-to-air exchanger project, with an average around $2,000. Typical per-unit equipment pricing runs $400-$1,800 for 60–200 CFM home units.
Assumptions: single-family home, 1–2 vents added, standard wall/crawlspace access, Midwest labor rates.
Major Quote Components: Equipment, Labor, Ducts, and Permits
Installation quotes typically break into equipment, labor, ducts/accessories, permits, and disposal.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $300-$1,500 | $400-$2,000 | $400-$3,500 | $0-$400 | $50-$300 |
Assumptions: labor 4–16 hours, hourly rates $75-$150.
How Unit Capacity and CFM Change the Final Price
Capacity is a primary price driver: residential 60–200 CFM units cost $400-$1,800 while 300–1,000 CFM commercial units cost $2,000-$10,000. Upgrading from 200 CFM to 400 CFM commonly increases equipment cost by 50%–150% and installation complexity.
Thresholds: small home <150 CFM often fits single-zone installation; multi-zone or whole-house ventilation >300 CFM requires larger ducts and higher labor rates.
Site Conditions That Add Significant Charges
Access and routing affect price—tight crawlspaces, multiple story runs, or rooftop installs add time and materials. Expect an extra $300-$2,500 for difficult access or vertical runs over 15 linear feet.
Other cost drivers include asbestos/lead abatement, noise mitigation, and sealing/insulation upgrades, each adding $200-$1,500 depending on scope.
Practical Ways To Reduce Air-to-Air Exchanger Price
Control scope: choose a right-sized unit, reuse existing ducts when feasible, and schedule installation in shoulder seasons to lower labor premiums.
- Provide pre-cut openings and clear attic/crawl access to reduce labor hours.
- Opt for mid-tier brand units ($700-$1,200) instead of premium models to save 20%–40% on equipment.
- Combine exchanger install with HVAC service or duct sealing to leverage contractor bundling discounts.
Regional Price Differences Across the U.S.
Prices vary by region: coastal urban areas typically run 10%–35% higher than Midwest or rural markets. For the same 150 CFM install expect $1,800-$3,200 in high-cost metro areas versus $1,000-$2,200 in lower-cost regions.
Cold-climate installations may need energy recovery ventilators (ERVs) vs. HRVs, adding $100-$500 to equipment cost but improving seasonal performance.
Typical Add-Ons, Timelines, and Example Quotes
Common add-ons include motorized dampers, filters, balancing, and condensation drains which add $150-$900 each.
| Example | Specs | Labor Hours | Parts + Labor |
|---|---|---|---|
| Basic Home | 100 CFM, wall-mounted, reuse ducts | 4–6 hours | $950-$1,600 |
| Whole-House | 250 CFM, new ducts, balancing | 8–14 hours | $2,400-$4,500 |
| Small Commercial | 600 CFM rooftop, curb, controls | 16–40 hours | $6,000-$12,500 |
Assumptions: quoted prices include materials, basic commissioning, and local labor; excludes major HVAC upgrades.
When Replacement Beats Repair for Price Control
Repairing aging exchangers may cost $150-$900 for fan motors, controls, or sensors, but units older than 10–15 years often need replacement. Replacing an old inefficient unit typically costs $1,200-$3,500 but avoids repeated repair charges and can reduce energy waste.
Compare the expected remaining life, repair frequency, and energy savings to decide whether repair or replacement gives better long-term pricing.
