An energy recovery ventilator (ERV) typically costs $2,000-$6,500 installed in a U.S. home, with many standard projects near $3,800. The final price depends on home size, ductwork, unit capacity, installation access, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed ERV system | $2,000 | $3,800 | $6,500 | Typical whole-house retrofit |
| ERV equipment only | $600 | $1,200 | $2,200 | Residential unit, before installation |
| New ductwork | $500 | $1,500 | $3,500 | Varies with run length and access |
| Labor | $700 | $1,500 | $3,000 | Installation and system balancing |
What a whole-house ERV installation usually costs
A basic installation using an accessible mechanical room and existing compatible ductwork can fall around $2,000-$3,500. A typical retrofit with dedicated intake and exhaust runs, electrical work, and balancing often totals $3,000-$5,000. Complex installations or high-capacity equipment can reach $5,000-$8,000 or more.
For a planning estimate, budget about $3,800 for a standard retrofit, not including major duct repairs or code upgrades. Equipment-only pricing commonly runs $600-$2,200; online unit prices are not directly comparable with an installed quote. Assumptions: 1,500-2,500-square-foot home, standard residential ERV, ordinary access, and no extensive duct replacement.
How ERV equipment, ductwork, and labor shape the quote
Quotes should separate the ventilator from the work needed to connect it. A lower equipment price may still require substantial duct installation, electrical connections, or commissioning. Ask whether the price includes airflow testing and balancing, since an installed unit needs correct supply and exhaust rates to work as intended.
| Quote component | Typical range | What it covers | Common price driver |
|---|---|---|---|
| ERV unit and controls | $600-$2,200 | Core equipment, basic controls | Capacity and features |
| Labor | $700-$3,000 | Mounting, connections, setup | Access and installation hours |
| Ductwork and fittings | $300-$3,500 | Intake, exhaust, and supply runs | Run length and routing |
| Electrical and permits | $150-$900 | Power connection and local fees | Existing wiring and local rules |
| Removal and disposal | $100-$500 | Old fan or equipment removal | Disposal needs and job scope |
At roughly $75-$150 per hour, 8-16 hours of HVAC labor can add $600-$2,400 before electrical work. A line-item quote makes it easier to distinguish equipment cost from installation complexity.
Why airflow capacity and duct runs change the price
ERV sizing is based on ventilation needs, not square footage alone. A smaller home with high occupancy may need more airflow than its area suggests. Residential units commonly serve roughly 50-200 cubic feet per minute (CFM); moving into a higher-capacity model can add $300-$1,000 or more, depending on controls and manufacturer.
Duct scope is another major variable. A short connection of under 20 feet may be straightforward, while separate intake and exhaust routes totaling 50 feet or more can add $800-$2,500 in materials and labor. Tight attic access, finished ceilings, and long exterior penetrations can increase installation time. Confirm the quoted CFM and duct route before comparing equipment prices.
How labor hours and access affect ERV installation time
A crew may complete a simple replacement or connection in 6-10 hours. A retrofit requiring new duct routes, ceiling access, or additional electrical work may take 1-2 days, often totaling 10-20 labor hours. Contractor minimum charges can make a short visit expensive, especially when a separate electrician or drywall repair is required.
Basements and unfinished utility spaces usually keep access costs down. Finished homes may need access panels or patching after duct installation; drywall repair and paint can add $200-$1,000 depending on the number and size of openings. Ask whether patching, electrical work, and final airflow balancing are included or billed separately.
ERV prices in high-cost cities and smaller markets
Local labor and permit requirements can shift an otherwise similar quote. Major coastal and high-cost metro areas may run 15%-30% above a national midrange estimate. Smaller cities and rural markets can be 5%-15% below it, although travel charges or fewer competing installers may narrow the difference.
These are planning adjustments, not fixed regional tariffs. A $3,800 standard project could land around $4,400-$4,950 in a higher-cost market or $3,200-$3,600 in a lower-cost area before unusual ductwork. Compare at least two local, scope-matched estimates rather than applying a national average as a guaranteed price.
What add-ons can push an ERV quote above budget
Old or undersized ducts, a new dedicated circuit, difficult exterior wall penetrations, and removal of existing equipment can add $150-$1,500 each, depending on the work. Roof or masonry penetrations may cost more than a simple wall cap. Permit fees often range from $50-$300 where required, while inspections or code-related corrections can increase the total.
Optional controls, upgraded filters, and humidity sensors may add $100-$700. Some homes need additional ventilation controls to coordinate the ERV with an existing HVAC system. Request a written list of included accessories and any exclusions before approving add-ons.
ERV versus HRV pricing for similar homes
An HRV, or heat recovery ventilator, often costs about $1,500-$5,500 installed, while an ERV commonly ranges from $2,000-$6,500. The equipment and installation prices overlap; the right comparison depends on climate, indoor humidity, and ventilation design. ERVs transfer some moisture along with heat, while HRVs transfer heat but not moisture.
Where either system can meet the ventilation plan, request quotes for both using the same airflow target and duct scope. A lower-priced unit is not a savings if it requires different ductwork or cannot meet the home’s ventilation needs. Compare installed totals and specified airflow, rather than unit prices alone.
Ways to reduce the installed ERV price without cutting capacity
Keep the project focused on required airflow and avoid paying for controls or accessories that do not solve a specific need. If existing ducts are clean, correctly sized, and well positioned, ask the contractor to price reuse separately from full replacement. Schedule the work before ventilation problems become urgent, when contractor availability may be better.
Get two or three written quotes that identify model, CFM, duct length, labor, permits, balancing, and warranty. Compare the same scope, and ask whether combining ERV work with other HVAC service can reduce a separate dispatch fee. Do not reduce system capacity simply to lower the bid; correct sizing and commissioning protect the value of the installation.
