Buyers typically pay $800-$4,500 for an air-to-air heat recovery exchanger depending on capacity, installation complexity, and controls; the cost and price vary widely by unit size and ductwork changes. This article lays out typical air to air exchanger cost ranges, per-unit pricing, major quote components, and practical ways to lower the final price. Assumptions: U.S. residential installations, standard single-family homes, normal access.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Unit Only (HRV/ERV) | $400 | $1,200 | $3,000 | Depends on CFM rating and features |
| Installed Complete | $800 | $2,200 | $4,500 | Includes labor, basic duct taps, controls |
| Per Vent/Accessory | $25 | $75 | $200 | Registers, balancing dampers, filters |
| Minor Duct Mod/Repair | $150 | $600 | $1,500 | Depends on access and materials |
What Homeowners Usually Pay For A Residential Air-To-Air Exchanger
Typical installed totals run $800-$4,500 for single-family homes with one to three supply/return connections. Average projects land near $2,200 for a mid-range ERV/HRV with 100-300 CFM capacity and basic controls.
Unit-only prices: $400-$3,000 depending on CFM (100-400 CFM), heat recovery efficiency, and whether the unit is ERV or HRV. Assumptions: Midwest labor rates, standard materials, normal attic or basement access.
Per-unit shorthand: small 100-150 CFM units $400-$900; medium 200-300 CFM $900-$1,800; high-capacity 300-400+ CFM $1,800-$3,000.
Breaking Down The Quote: Materials, Labor, Equipment, Permits
A full quote usually separates materials, labor, equipment, and permit fees; understanding each helps spot padding. Expect materials and labor to consume roughly 70%-85% of the installed price.
| Materials | Labor | Equipment | Permits |
|---|---|---|---|
| $300-$2,200 (unit, ducts, filters) | $300-$1,800 (installation, balancing) | $50-$400 (tools, lifts, test gear) | $0-$250 (local filings) |
Typical labor: 4-12 hours for straightforward installs; 12-24+ hours with major ductwork or ceiling penetrations.
How Capacity, CFM, And Efficiency Change The Final Price
CFM and efficiency ratings are primary price drivers; moving from 150 CFM to 300 CFM often doubles unit cost and increases labor for larger duct runs. Numeric thresholds: under 150 CFM (low-cost range), 150–300 CFM (mid-range), over 300 CFM (high-cost range).
Efficiency/heat-recovery effectiveness (sensible recovery %) also affects price: basic units 50%-60% vs. high-efficiency 80%+ can add $300-$1,000 to the unit cost.
Site Conditions That Increase Installation Price
Access, duct condition, and number of penetrations matter; attic or crawlspace access typically keeps costs lower than wall or roof penetrations. Hard thresholds: more than 6 linear feet of new ductwork or 3+ wall/roof penetrations usually add $400-$1,200.
Complicated balancing, asbestos or mold remediation, or custom sheet metal can add $500-$2,000 to the job depending on scope and remediation needs.
Practical Ways To Lower Your Air-To-Air Exchanger Price
Control scope: choose correct CFM for home size, avoid oversizing, and reuse existing duct where possible. Prepping access and doing basic demolition or clearing route access can save $100-$500 in labor.
Compare at least three quotes, bundle work with HVAC service visits, select factory-basic controls, and avoid premium finishes. Repairs instead of full replacement of short duct runs often save $200-$800.
Regional Price Differences And Seasonal Effects On Quotes
Costs vary regionally: Northeast/West Coast often 10%-25% higher than Midwest/South for labor and permits. Example deltas: Midwest base, Northeast +15%, West Coast +20%, Rural -10% on labor rates.
Seasonal demand: fall and winter can raise labor rates or lead times; scheduling in spring or late summer may lower quotes by 5%-12% and shorten wait times.
Common Add-Ons, Balancing, And Warranty Costs To Expect
Common extras include commissioning/balancing ($150-$500), additional filters $30-$120 each, and controls or smart integration $150-$600. Extended warranties or parts plans often cost $75-$300 per year.
| Add-On | Low | Average | High |
|---|---|---|---|
| Commissioning/Balance | $150 | $300 | $500 |
| Smart Controls/Integration | $150 | $350 | $600 |
| Additional Filter Kits | $30 | $75 | $120 |
Three Real-World Quote Examples To Compare
Example A: Small condo, 120 CFM HRV unit $400, labor 4 hours $300, minor duct tap $150 — total $850. Good for: single-room ventilation or small condo.
Example B: Typical 2,000 sq ft home, 250 CFM ERV $1,300, labor 8 hours $700, duct modifications $450, balance $300 — total $2,750. Represents average mid-range install.
Example C: High-capacity 350 CFM ERV with high-efficiency core $2,200, complex roof penetrations 18 hours labor $1,600, sheet metal custom $900 — total $5,700 (high end). High-access or multi-penetration jobs jump cost quickly.
