A residential heat recovery unit, usually called an HRV, costs about $2,000-$6,500 installed for a standard whole-house project; complex retrofits can reach $10,000 or more. Heat recovery unit price depends on airflow capacity, ductwork, electrical work, access, and whether the home needs an HRV or an energy recovery ventilator (ERV).
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Residential HRV installed | $2,000 | $4,200 | $8,000+ | Existing ducts and straightforward access reduce labor |
| HRV equipment only | $700 | $1,600 | $3,000 | Price varies by airflow, controls, and efficiency |
| New duct runs | $500 | $1,500 | $3,500+ | Depends on length, route, and number of rooms |
| ERV installed | $2,500 | $4,800 | $9,000+ | Comparable project with humidity-transfer equipment |
What a residential heat recovery unit costs installed
For a typical 1,500- to 2,500-square-foot U.S. home, a standard HRV with roughly 100-200 cubic feet per minute (CFM) of capacity often totals $2,000-$6,500 installed. A practical national planning figure is around $4,200, assuming ordinary access, moderate duct modifications, and a midrange unit. Larger homes, extensive new ductwork, and difficult routing can push the quote above $8,000.
Equipment alone commonly runs $700-$3,000. A basic unit near the lower end may suit a small home or limited ventilation demand, while higher-capacity models with quieter fans, better controls, or more efficient heat exchange cost more. Installation adds roughly $1,000-$4,000 for labor, materials, setup, and testing, but major retrofit work may exceed that range.
For a standard retrofit, compare the complete installed price rather than the equipment sticker price. One quote may include new supply and exhaust ducts, controls, balancing, and commissioning; another may assume that most of those items already exist. Assumptions: Typical U.S. residential labor, midrange equipment, normal access, and no major electrical or building-code upgrades.
How HRV equipment, ductwork, and labor appear in quotes
A contractor’s estimate may combine several tasks into one price, so an itemized breakdown helps identify what is included. The ranges below describe common residential work and are not all additive: existing ducts, a bundled installation rate, or regional labor pricing can change the total.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| HRV unit | $700-$1,000 | $1,000-$2,000 | $2,000-$3,000 | Residential equipment, roughly 100-250 CFM |
| Labor | $600-$1,200 | $1,200-$2,500 | $2,500-$4,500 | Mounting, connections, controls, and testing |
| Ducts and fittings | $300-$700 | $700-$1,800 | $1,800-$3,500 | Branches, insulated duct, grilles, and transitions |
| Electrical and controls | $150-$350 | $350-$800 | $800-$1,500 | Power, wall control, sensors, or wiring changes |
| Removal and disposal | $100-$250 | $250-$500 | $500-$900 | Old unit removal or difficult disposal |
Labor may be priced as a fixed installation charge or estimated at about $75-$150 per hour, depending on trade and location. A straightforward replacement can take 6-10 labor hours; a new installation with long duct runs can require 12-24 hours across a crew.
Ask whether duct balancing and airflow commissioning are included. These steps help confirm that the unit delivers the intended ventilation rate; a low quote that excludes them may not represent an equivalent finished job.
Which airflow rating, duct length, and climate conditions raise the price
Capacity is one of the clearest equipment price drivers. A unit rated around 80-150 CFM may cost $700-$1,700, while 150-250 CFM models commonly run $1,200-$2,800. Homes needing more than 250 CFM may require larger equipment or multiple ventilation zones, with equipment and installation together potentially exceeding $8,000. A contractor should size the system for the home and ventilation plan, rather than selecting by square footage alone.
Duct scope can shift the total substantially. Reusing suitable ducts may keep the installation near the lower end, while adding 30-60 feet of insulated duct, several room branches, or separate intake and exhaust routes can add $800-$3,000. Running ducts through finished ceilings or multiple floors may cost more than routing them through an unfinished basement or attic. Exterior wall penetrations and weatherproof hoods also need to be included.
Climate and moisture conditions influence the choice between an HRV and an ERV. HRVs transfer heat and are commonly considered in colder, drier regions; ERVs also transfer some moisture and may suit humid climates or homes where humidity control is a priority. ERV equipment often costs $200-$800 more than a comparable HRV, although installation scope matters more than the unit premium.
Capacity, route length, and finish access can matter more than the brand name. A 200-CFM unit installed beside an open mechanical room may cost less overall than a smaller unit requiring concealed duct runs and extensive ceiling repair.
How long HRV installation takes and what labor includes
A replacement using compatible ducts and electrical connections may take one working day, or about 6-10 labor hours. A first-time installation often takes 1-3 days because the crew must mount the unit, create intake and exhaust paths, run branch ducts, install controls, and seal exterior penetrations. Work in a finished home can take longer if access panels or drywall repairs are needed.
At $75-$150 per labor hour, direct labor for a simple 8-hour job pencils out to about $600-$1,200 before materials, overhead, and any specialist subcontracting. Larger jobs may involve two technicians for part of the work, an electrician, or an HVAC contractor handling both duct installation and system balancing. Hourly rates are a comparison tool, not a reliable substitute for a written scope.
Commissioning should cover airflow checks, control operation, and basic instruction on filter access and maintenance. If balancing is listed separately, it may add $150-$500 depending on the number of supply and exhaust points. Ask whether the installer will document airflow readings and explain the recommended filter replacement schedule.
Schedule around access and finish work, not just the advertised installation day. A contractor may complete mechanical installation quickly but need additional time for inspection, drywall patching, or follow-up balancing when the house has complicated duct routes.
What retrofit conditions add to a heat recovery unit estimate
Replacing an old HRV is generally less costly than adding ventilation from scratch. A like-for-like replacement may land around $1,500-$4,000 when the duct connections, mounting location, and electrical supply remain usable. Adapting mismatched ducts, moving the unit, or replacing deteriorated insulation can bring the job closer to $4,000-$7,000.
New installations can include extra charges for drilling through masonry, working in a cramped attic, running ducts through finished spaces, or creating access openings. Those complications may add $300-$2,000 or more. Drywall repair and painting are often outside an HVAC quote, so homeowners should confirm who handles them and whether the estimate includes patching.
Old equipment removal may cost $100-$500, though some contractors include it in the replacement price. A new circuit or electrical correction can add $200-$1,000, and permits or inspections may add roughly $50-$400 where required. Local rules differ, so the contractor should identify permit responsibility before work begins.
Separate necessary upgrades from optional improvements in the written estimate. A damaged duct or unsafe electrical connection may need correction, while relocating a functioning system for convenience may be deferrable. Requesting separate line items makes those choices easier to assess.
HRV or ERV pricing compared with repair and replacement
An HRV and an ERV both exchange stale indoor air for outdoor air while recovering energy from the outgoing air. HRV equipment typically costs about $700-$3,000, compared with roughly $900-$3,500 for an ERV of similar residential capacity. Installed prices often overlap: approximately $2,000-$8,000 for an HRV and $2,500-$9,000 for an ERV, with ductwork and access driving much of the difference.
Repair may be economical when the cabinet and heat-exchange core are sound. A diagnostic visit often costs $100-$250, and common repairs such as replacing a motor, control, or sensor may total $200-$900 including labor. A replacement core or multiple failed components can cost $500-$1,500, making a new unit worth comparing when the existing system is older or has recurring problems.
For a replacement decision, compare the repair quote with the installed price and the condition of the ducts. A $400 control repair is different from a $1,300 motor-and-core repair on an aging unit. A new system also may require updated controls or duct connections, so “equipment-only” replacement pricing is not a fair comparison with a repair invoice.
Choose by ventilation needs and climate, not by the lower unit price alone. An ERV’s moisture transfer may be useful in some homes, while a well-sized HRV may be a less expensive fit elsewhere; a qualified contractor can explain the design basis.
How U.S. location and home layout shift installed rates
Labor and contractor availability vary across the country. A straightforward job in a lower-cost market may be 10%-20% below the national planning range, while high-cost metro areas can run 15%-35% above it. Remote locations can also cost more because of travel time, limited installer availability, or delivery charges, even when local wages are lower.
Climate affects equipment selection and installation details more than it creates a fixed regional surcharge. Cold-weather projects may need careful intake and exhaust placement, insulated ductwork, and condensation management. In humid areas, an ERV may be quoted more often. These choices can add several hundred dollars in equipment or materials, but site layout and duct access still determine much of the final bill.
Home configuration matters at least as much as the ZIP code. An unfinished basement near the air handler can simplify duct routing; a two-story house with finished ceilings may require long runs and more labor. Ask contractors to specify whether the quote assumes access through a basement, attic, utility room, or finished living space.
Use regional percentages as a planning adjustment, then compare local itemized quotes. Two estimates from the same city can differ because one includes duct balancing and finish repairs while the other covers only the unit and basic connections.
Where homeowners can trim heat recovery unit costs
Keeping the project focused is usually the most reliable way to control price. Confirm the required airflow, rooms served, and equipment location before approving a larger capacity or extra zones. Avoid paying for capacity that the design does not support, but do not undersize the unit simply to reduce the initial invoice.
Use existing ducts only when they are correctly sized, clean, sealed, insulated where needed, and suitable for the new system. Reuse can save several hundred dollars to more than $1,000, but unsuitable ductwork may reduce performance or require later corrections. Ask the contractor to identify which ducts will be reused and which will be added or replaced.
Obtain at least three written estimates with matching assumptions: model or capacity, duct footage, electrical work, controls, removal, balancing, warranty, and permit handling. Compare the installed total and exclusions rather than choosing the lowest headline price. Scheduling during a less busy period may improve availability, although seasonal savings are not guaranteed.
Control upgrades and scope before negotiating the equipment line. A standard wall control may be sufficient when advanced sensors are not needed, and an existing unit’s repair should be priced against replacement before a full system is ordered. Do not remove commissioning or necessary safety work solely to reduce the quote.
