Buyers typically pay $900-$6,500 to install a residential air exchanger; total price depends on unit size, ventilation type, and installation complexity. This article focuses on air exchanger cost and the main drivers contractors use when quoting equipment, labor, and additional work.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole‑house ERV/HRV Unit | $600 | $1,200-$2,000 | $3,500 | Unit only; variable by CFM and brand |
| Installed Single‑Zone System | $900 | $1,800-$3,500 | $6,500 | Includes labor, basic duct tie‑ins |
| Complex Retrofit (new ducts, roof chase) | $2,500 | $4,500-$7,500 | $12,000 | Extensive work, multiple penetrations |
| Permits & Extras | $0 | $50-$300 | $800 | Depends on local code and electrical work |
Typical Total Price for a Whole‑House Air Exchanger
Most homeowners pay between $1,800 and $3,500 for a typical whole‑house ERV or HRV installed in a single‑family home with existing ducts. Expect the average installed price to be $1,800-$3,500 for 100-300 CFM units in normal access conditions.
Assumptions: Midwest labor rates, 150-250 CFM unit, single‑story or attic access, standard passive duct connections.
Costs Broken Down: Materials, Labor, Equipment, and Permits
A homeowner’s estimate should separate unit cost, installation labor, ducts/electrical, and any permit fees to compare quotes accurately.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $600-$3,500 (unit price; 150-400 CFM) | $300-$1,800 (; 3-12 hours typical) | $50-$400 (mounts, grilles, controls) | $0-$300 (local permit and inspection) | $0-$250 (old unit disposal, crates) |
How Capacity (CFM), Efficiency, and Duct Complexity Change the Price
Capacity and efficiency strongly affect both unit and operating cost: a 150 CFM basic HRV costs $600-$1,200 while a 300-400 CFM highly efficient ERV with heat recovery features is $1,500-$3,500. Doubling CFM typically increases unit price 40%-100% and may increase labor 20%-60% due to larger ducts or multiple penetrations.
Duct complexity thresholds: up to 100 linear feet of tie‑in is low complexity; 100-300 linear feet is medium; over 300 linear feet, or multiple story runs, pushes quotes into high complexity territory.
Practical Ways To Lower Your Air Exchanger Price
Control scope by choosing a right‑sized unit, preparing access, and avoiding unnecessary new duct runs to cut costs.
- Opt for a mid‑efficiency 150-250 CFM unit when home size and airtightness allow.
- Prepare the site: clear attic space, mark duct routes, and ensure easy electrical access to reduce onsite labor hours.
- Bundle with HVAC service or other home projects to lower contractor overhead markup.
- Request multiple quotes that separate materials and labor to negotiate specific line items.
How Installation Time, Crew Size, and Hourly Rates Affect the Quote
Installation time typically ranges 3-12 hours. Expect small jobs to take one 2‑technician crew 4-6 hours at $75-$125 per hour per tech, while complex retrofits may need 8-16 crew‑hours.
Example time thresholds: simple replacement — 3-5 hours; moderate duct tie‑ins and controls — 6-10 hours; new ducting or structural penetrations — 10+ hours. Travel, minimum charges, and after‑hours service can add $50-$300.
Typical Add‑Ons, Removal Fees, and Site Complications That Raise Price
Expect extra charges for electrical upgrades, new ducts, roof or wall penetrations, and decommissioning old systems.
| Extra | Low | Average | High |
|---|---|---|---|
| Old unit removal | $0 | $50-$150 | $300 |
| Electrical hookup / new circuit | $150 | $250-$600 | $1,200 |
| New short duct runs / boots | $200 | $400-$900 | $2,000 |
| Roof or wall chase | $300 | $700-$1,500 | $3,500 |
How Prices Vary Across U.S. Regions and Seasons
Regional labor differentials change installed price by roughly ±15%-35% from national averages: Northeast and West Coast tend to be 15%-35% higher; Midwest and South often 10%-20% lower.
Seasonality: HVAC contractors are busiest in summer and winter; shoulder seasons (spring/fall) can yield faster scheduling and slightly lower labor rates or promotional pricing.
Three Real‑World Quote Examples With Specs and Totals
Concrete quotes help budget: below are realistic scenarios contractors provide.
| Scenario | Specs | Labor Hours | Unit+Materials | Total |
|---|---|---|---|---|
| Simple replacement | 150 CFM HRV, attic access | 4 | $800 | $1,200-$1,600 |
| Moderate retrofit | 250 CFM ERV, duct tie‑ins, new controls | 8 | $1,600 | $3,000-$4,200 |
| Complex retrofit | 350 CFM high‑efficiency ERV, new ducts, chase | 16+ | $3,000 | $6,500-$12,000 |
Readers should use these ranges to request line‑item quotes and verify assumptions about CFM, efficiency, access, and electrical needs when comparing bids.
