Homeowners commonly pay for an air exchanger to improve indoor air quality and energy efficiency. The cost of a residential air exchanger, including a heat-recovery ventilation (HRV) or energy-recovery ventilation (ERV) unit, depends on unit type, performance, ductwork, and installation labor. This article breaks down the typical price, per-unit costs, and regional factors to help buyers estimate a realistic budget for a home air exchanger.
Assumptions: Midwest to Southeast labor rates, standard 2-zone central system, typical 60-100 CFM capacity, mid-range ERV/HRV model, normal attic or crawlspace access.
Itemized Price Tag for a Residential Air Exchanger
Typical total cost ranges including equipment and basic installation are $2,000 to $5,500. For a standard 2- to 3-bedroom home with a mid-range unit, expect closer to $2,500-$4,000, while larger homes or higher-efficiency models can reach $4,500-$5,500.
Cost Components Behind the Quote
The quote breaks into major parts: equipment, labor, ductwork, and permits. Equipment and installation often comprise the lion’s share of the price.
- Equipment: $1,200-$2,800 for the unit itself, depending on CFM, efficiency rating, and brand.
- Labor: $800-$2,000 for installation, including mounting, wiring, and commissioning.
- Ductwork: $500-$2,000 if new ducts are needed or existing ducts require modification.
- Permits and inspections: $100-$500 depending on local codes.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Air exchanger unit | $1,200 | $1,800 | $2,800 | ERV or HRV, 60-100 CFM |
| Labor and installation | $800 | $1,500 | $2,000 | Includes basic wiring and commissioning |
| Ductwork and routing | $500 | $1,200 | $2,000 | Existing vs new runs |
| Permits and inspection | $50 | $250 | $500 | Local code requirements |
| Total installed price | $2,000 | $3,000 | $5,500 | For typical homes |
How the Unit Size Drives Price
Air exchangers are rated by airflow, measured in CFM. A 60-100 CFM unit handles a small-to-medium home, while 150-200 CFM supports larger spaces. Higher CFM units start around $1,900-$2,400 before installation. In contrast, premium high- performance models with passive cooling, higher efficiency, and quieter operation can push equipment costs to $2,600-$4,000.
Regional Price Variations That Matter
Costs differ by region due to labor rates and climate. In the Northeast and West Coast, expect higher installation labor and permitting fees compared with the Midwest and Southeast. Installed price ranges by region commonly fall within $2,600-$5,000 for the same model. When weather extremes demand more robust ductwork or additional controls, prices rise accordingly.
System Type Matters: ERV vs HRV vs Hybrid
ERV units recover both heat and humidity, while HRV units focus on heat exchange. Hybrid systems blend features. Equipment price tends to be $1,400-$2,500 for HRVs, $1,700-$3,000 for ERVs, with hybrids landing $2,200-$3,500. Installation complexity, duct routing, and controls add to the total.
Labor Time and Crew Size You Can Expect
Typical installation takes 1-2 days for a straightforward setup, with 2-4 tradespeople on site. Labor costs usually range from $800-$1,800 for standard work in a typical home. Complex attic routing, tight spaces, or multiple zones can push labor to $2,000-$3,000.
Ductwork Scope and Its Price Impact
Existing duct systems can lower costs if they align with the new exchanger’s duct connections. Replacing or adding runs increases price. New duct installs or extensive rerouting can add $500-$2,000 to the total. Duct sealing and insulation may add $100-$300.
Permits, Inspections, and Code Upgrades
Some jurisdictions require permits for ventilation equipment installation. Permit costs vary widely. Budget $100-$500 for permit fees and inspections. Code upgrades or energy-efficiency mandates can influence the choice of unit and layout.
Smart Controls and Optional Upgrades
Smart thermostats, humidity sensors, and automatic damper controls can improve comfort and efficiency but add to the upfront price. Basic controls: $100-$300; premium modules: $400-$800. Wireless integration or app-based monitoring may incur additional setup fees.
Maintenance Costs That Change Over Time
Annual maintenance includes filter checks and fan operation. Estimated ongoing costs: $75-$150 per year for filter replacements and inspection. Replacements for filters, seals, or motor parts can occur every 5-10 years depending on usage and climate.
Two Real-World Scenarios: Quick Comparisons
Scenario A: 1,500-square-foot, 60 CFM ERV in a suburban home with existing ducts. Total installed price: $2,400-$3,200. Scenario B: 2,800-square-foot home needing 100 CFM HRV with new duct routing in a cold climate. Total installed price: $4,000-$5,500.
What A Typical Quote Might Look Like
Quote example 1: Unit 70 CFM ERV, installed, with 3 zones and new runs. Equipment: $1,600; Labor: $1,200; Ducts: $900; Permits: $150. Total: $3,750.
Quote example 2: 120 CFM HRV, existing ducts, smart controls, Midwest region. Equipment: $2,000; Labor: $1,600; Ducts: $400; Permits: $100. Total: $4,100.

How to Cut the Price Without Sacrificing Value
Carefully manage scope and timing. Bundle the air exchanger with related HVAC work when possible to reduce trips and labor charges. Compare quotes from multiple contractors, and consider whether to repair an existing system or replace with a single, appropriately sized unit. Choose standard controls over premium smart features unless the extra benefit justifies the cost.
Key Takeaways for Budget Planning
The price of a residential air exchanger usually sits in the $2,000-$5,500 installed range, influenced by unit size, ERV vs HRV type, ductwork needs, regional labor rates, and permit requirements. Early qualification of CFM needs and duct layout avoids overpaying for an oversized system.
