An exhaust air heat pump typically costs about $8,000-$18,000 installed in the United States, with complex whole-home projects reaching $25,000 or more. Equipment availability, heating capacity, duct and ventilation changes, electrical work, and local labor rates have the biggest effects on the quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed exhaust air heat pump | $8,000 | $13,000 | $25,000+ | Equipment and typical installation; major duct or electrical upgrades can exceed the high range. |
| Equipment only | $4,000 | $7,500 | $12,000 | Availability and whether a ventilation or hot-water package is included affect price. |
| Installation labor | $2,000 | $4,000 | $8,000 | Higher for new ducts, extensive controls, or difficult access. |

What an installed exhaust air heat pump costs
For a home with suitable mechanical ventilation, a practical planning range is $8,000-$18,000 installed. A straightforward replacement with compatible ducts and electrical service may fall near $8,000-$12,000. A new installation involving duct modifications, a hot-water cylinder, controls, or backup heating can run $15,000-$25,000 or more.
These systems capture heat from indoor air removed by a ventilation system, then transfer some of it to domestic hot water or space heating. They are not interchangeable with every ductless air-source heat pump. Many products sold in Europe are designed for specific ventilation layouts, so U.S. buyers should confirm local availability, parts support, and code acceptance before relying on a catalog price.
For a standard retrofit, budget around $13,000 before unusual electrical, duct, or structural work.
Assumptions: Existing home, standard equipment, ordinary access, and U.S. contractor pricing; regional rates and system scope vary.
How equipment, ductwork, and labor shape the quote
Written estimates should separate the heat pump from ventilation, hot-water storage, electrical work, and commissioning. A low equipment price may exclude a tank, duct transitions, controls, or the labor needed to make an imported or less-common model work with the home’s existing system.
| Quote component | Typical price | What changes the charge | Common unit |
|---|---|---|---|
| Heat pump and controls | $4,000-$12,000 | Capacity, integrated features, brand support | Per system |
| Ventilation ducts and fittings | $500-$3,000 | New runs, sealing, access, number of grilles | $10-$35 per linear ft |
| Hot-water tank or cylinder | $800-$2,500 | Capacity, insulation, and controls compatibility | Per tank |
| Installation and commissioning | $2,000-$6,000 | Installer experience, system integration, testing | $75-$150 per hour |
| Electrical and disposal | $300-$2,000 | New circuit, panel work, removal of old equipment | Per project |
Permit charges are often $100-$600 where mechanical or electrical permits are required, though local fees can be higher. A contractor may also charge $150-$400 for a diagnostic or site assessment if the existing ventilation system needs detailed evaluation. Ask whether those amounts are included or credited toward the installation.
The most useful quote comparison is a complete installed scope, not the equipment price alone.
Why airflow, tank size, and duct runs change the price
System sizing depends on the building’s continuous exhaust airflow, heating demand, and hot-water use. A small unit serving roughly 100-150 cubic feet per minute (CFM) of exhaust may cost less than a model intended for 200-300 CFM, but airflow alone does not determine heating capacity. The contractor should explain the rated output and how much backup heat the home will need during cold weather.
Tank size also affects the total. A 40-50-gallon tank may suit a smaller household, while a 60-80-gallon cylinder can add equipment and installation expense. Larger storage can help meet peak demand, but it does not automatically improve efficiency; the heat pump and controls must be matched to the tank and household use.
Duct layout is another major variable. Reusing sealed, correctly sized exhaust ducts may keep modifications near $500-$1,500. Replacing long runs, adding grilles, or correcting undersized ducts can add $2,000-$5,000 or more. A duct run over 30 feet, multiple floor penetrations, or a tight mechanical closet can increase both material and labor needs.
Electrical requirements vary by equipment. A compatible nearby circuit may require little work, while a new dedicated circuit can add about $300-$1,200. Panel replacement or service upgrades are separate scope and can cost several thousand dollars.
Confirm the required CFM, heating output, tank capacity, and duct work in writing before accepting a price.
How long installation takes and what labor includes
A replacement using compatible ductwork can take one to two days, often involving two technicians. A new system with duct changes, tank installation, electrical work, and controls can take two to four days; complicated projects may take longer if inspections or equipment delivery delay completion.
At roughly $75-$150 per technician hour, a two-person crew working 16-32 combined hours represents about $2,400-$9,600 in labor before overhead, depending on how the contractor calculates crew time. Many bids use a fixed installation price instead.
Labor should cover setting and connecting the unit, sealing or adapting ductwork, wiring and controls, condensate management if applicable, startup, airflow checks, and homeowner instructions. Ask whether commissioning is included and whether the installer will document airflow and operating settings. If a system is unfamiliar locally, confirm that the technician can source parts and provide service after installation.
Installation time matters most when the quote includes new ducts, tank work, or electrical upgrades.
Regional labor rates and equipment access across the U.S.
Pricing can differ by roughly 10%-25% between lower-cost rural markets and major metropolitan areas, mainly because of labor, travel, permit, and contractor overhead. In high-cost coastal cities, an otherwise standard $13,000 installation might reach $15,000-$17,000. In a lower-cost market with a qualified installer, comparable work may land around $10,000-$12,000.
Local availability can matter more than distance alone. Exhaust air heat pumps are less common in the U.S. than conventional air-source heat pumps, and some models have limited distribution. A specialist may charge for sourcing equipment or adapting a product to local electrical and plumbing requirements. Imported equipment can also involve shipping, customs, warranty, and replacement-part risks that are not reflected in an online listing.
Climate affects expected performance and system design as well. Cold regions may require a larger backup heat source or different controls, while mild climates can reduce heating demand. Those needs should be reflected in the load calculation rather than handled through an oversized unit by default.
Compare local, fully installed bids that specify service support and code compliance, especially for less-common equipment.
Three sample exhaust air heat pump quotes
These examples illustrate how scope changes the total; they are not fixed national rates. Each assumes ordinary residential access and does not include major panel replacement or extensive building repairs.
| Project | Scope and labor | Estimated total | Price basis |
|---|---|---|---|
| Compatible replacement | Existing ducts and tank retained; 2-person crew, 16 hours | $8,500-$11,500 | Equipment $4,500-$7,000; labor and startup $2,500-$3,500 |
| New system in a 1,500-sq-ft home | Moderate duct changes, new 50-gallon tank; 2-person crew, 24 hours | $13,000-$18,000 | Equipment and tank $6,000-$9,000; duct work $1,000-$2,500 |
| Large retrofit with difficult access | Long duct runs, upgraded circuit, 65-gallon tank; 2-person crew, 32 hours | $19,000-$27,000 | Equipment $8,000-$12,000; labor, electrical, and duct work $8,000-$12,000 |
In the first example, replacing a compatible unit avoids extensive construction. The second includes modest changes to serve the new equipment. The third allows for a larger scope and access challenges, but a quote above $25,000 should identify each upgrade separately and explain why it is needed.
Use the scope and line items to compare sample totals; a higher price is not meaningful without the work it covers.
How it compares with air-source heat pumps and ventilation units
A conventional air-source heat pump often costs about $8,000-$18,000 installed for a ductless multi-zone system, or $10,000-$25,000 for many ducted replacements. Those systems collect heat from outdoor air and can provide substantial space heating and cooling. An exhaust air heat pump instead recovers heat from indoor ventilation exhaust, so its output and suitability depend on the home’s airflow and heating load.
A heat-recovery ventilator or energy-recovery ventilator typically costs about $2,000-$6,000 installed, depending on ductwork and controls. It recovers heat or energy from exhaust air to temper incoming ventilation air, but it does not usually provide the same domestic hot-water function as an exhaust air heat pump. It may be a more appropriate comparison when the main goal is ventilation efficiency rather than water heating or space heat.
Repairing an existing ventilation fan or replacing a hot-water heater may cost less upfront, often $300-$1,500 for a fan replacement or $1,000-$3,500 for a standard water-heater replacement. Those are not equivalent upgrades, but they can avoid a large integrated-system purchase when only one component has failed.
Compare systems by the services they deliver, not by equipment names or purchase price alone.
Where a lower quote can save money without cutting performance
Retaining sound ducts, a compatible tank, and usable wiring can avoid thousands of dollars in replacement work. Before installation, clear access to the mechanical area and identify existing plans, equipment labels, and service records. The contractor should verify that retained components meet the new unit’s airflow and control requirements rather than assume they will fit.
Request at least three itemized bids using the same capacity, tank size, duct scope, and commissioning requirements. If a quote is substantially lower, check whether it omits permits, electrical work, removal, balancing, or startup. If a quote is much higher, ask for the specific equipment model and a line-by-line explanation of duct or panel upgrades.
Keep optional smart controls, premium monitoring, and nonessential duct replacements separate from code-required work. Avoid choosing a smaller unit solely to lower the price: inadequate output can increase backup-heating use and reduce comfort. Conversely, oversizing without a documented load calculation can add cost without a corresponding benefit.
Scheduling outside peak heating-season demand may improve installer availability, though it does not guarantee a lower equipment price. Ask whether a diagnostic fee is credited, whether disposal is included, and how warranty service will be handled if the equipment is not widely stocked locally.
The safest savings usually come from a clearly limited scope, reusable compatible components, and comparable written bids.
