Prices for mechanical heat recovery ventilation (MHVR) systems vary by unit size, performance, and installation scope. This guide presents cost ranges, per unit pricing, and the main drivers behind the total price to help buyers budget accurately for MHVR projects.
Assumptions: Midwest to Northeast labor rates, standard 4-inch ductwork, residential single-family home, and a mid-range MHVR unit with common core efficiency.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| MHVR Unit (core only) | $500 | $1,100 | $2,000 | Includes heat exchangers, fan, controls |
| Installation Labor | $1,200 | $2,200 | $4,000 | Assumes accessible attic/basement |
| Ductwork Modifications | $300 | $1,200 | $3,000 | Perimeter runs, leaks addressed |
| Electrical & Controls | $150 | $550 | $1,000 | New circuit, wiring, thermostat |
| Permits & Inspections | $50 | $350 | $700 | Local city or county requirements |
| Delivery/Logistics | $0 | $100 | $350 | Dealer delivery or freight |
What Buyers Pay For Mechanical Heat Recovery Ventilation
Typical total price includes the MHVR unit, installation labor, and necessary duct and electrical work. For a standard 1,000 to 1,500 square foot home, total project price commonly ranges from $2,000 to $6,000, with midrange installs clustering around $3,500 to $4,500 depending on duct routing and attic access.
Assumptions cover a single MHVR unit replacing or augmenting an existing system, standard humidity and temperature sensors, and a basic wall or ceiling intake/exhaust placement. Per-unit pricing helps compare options when upgrading to higher efficiency cores or larger airflow capacity.
The quote breaks into major parts that aggregate into the total price. A typical breakdown shows unit cost, labor, duct modifications, and permits, with delivery as a minor add-on in some regions.
Table shows a practical cost view for a 1,000–1,500 sq ft home. The per-unit MHVR core price plus labor dominates the upfront expense, while ductwork and electrical work scale with home accessibility and desired airflow.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| MHVR Unit Core | $500 | $1,100 | $2,000 | Heat exchanger type and efficiency impact price |
| Labor to Install | $1,200 | $2,200 | $4,000 | Crew size and access drive costs |
| Duct Modifications | $300 | $1,200 | $3,000 | New runs, sealing, flex vs metal |
| Electrical/Controls | $150 | $550 | $1,000 | Thermostat or smart control wiring |
| Permits | $50 | $350 | $700 | Local permit fees and inspections |
| Delivery | $0 | $100 | $350 | Logistics charges if applicable |
Two numeric thresholds commonly change the quote: airflow rating and duct length. An MHVR with 60 CFM per room and 150 CFM total for a compact home tends to be cheaper than a high-performance 120 CFM per room or 300+ CFM total system, especially if long duct runs or multiple zones are required.
Other influential factors include stairwell access, attic insulation level, and the number of zones or branches in the system. For two-story homes with limited attic space, installation time and duct fabrication can increase price notably.
Regional labor costs and shipping influence total MHVR price. In suburban markets, installed costs often sit near the national average, while urban cores may see a 10–25% uplift and rural areas can be 5–15% lower due to labor supply and transport.
Assuming standard permits and a midrange unit, expect regional differences to shift the average price by roughly $300 to $900 in most cases.
Per unit pricing helps compare multiple unit sizes or upgrade paths. A common approach lists the MHVR core per unit price along with incremental costs for higher efficiency cores or larger airflow capacity, plus a separate line for each additional zone or unit if needed.
The following example illustrates a two-unit scenario in a two-zone home, showing the combined effect on total cost and unit economy.
| Item | Units | Unit Price | Line Total | Notes |
|---|---|---|---|---|
| MHVR Core 60 CFM | 1 | $1,100 | $1,100 | Standard efficiency |
| MHVR Core 120 CFM | 1 | $1,800 | $1,800 | Higher capacity |
| Installation Labor | 2 hours | $110/hr | $220 | Pro-rated |
| Ducting Add-ons | 1 job | $600 | $600 | Moderate runs |
Residential single-zone vs multi-zone MHVR changes the bottom line. A single-zone system might cost around $2,000 to $4,000, while a four-zone layout with longer duct runs can push total toward $6,000 to $9,000 depending on installation difficulty and control complexity.
Consider whether a heat recovery ventilator is placed in an attic, crawlspace, or utility closet, as location affects both labor time and materials like duct length and supports.
Scope control and material choices drive real savings. Choose a midrange core if building airtightness meets code, avoid premium sensors, and minimize unnecessary zoning. Scheduling work during off-peak seasons can also reduce labor quotes by 5–15% in some markets.
Practical steps include bundling the MHVR install with other duct or HVAC work, reusing existing duct runs where feasible, and selecting standard duct sizes to avoid custom fabrication.
Real-world quote examples help set expectations. Example A covers a 1,200 sq ft home with a single MHVR unit and limited duct work, totaling about $3,200. Example B uses two zones and longer runs, reaching around $6,500. Example C is a high-efficiency, multi-zone install near $8,800.
| Scenario | Unit Type | Labor Hours | Total Price | Notes |
|---|---|---|---|---|
| Single MHVR, 1 zone | 60 CFM core | 8 | $3,200 | Standard install |
| Two MHVR units, 2 zones | 60/90 CFM cores | 14 | $6,500 | Moderate ducting |
| High efficiency, 3 zones | 120 CFM cores | 18 | $8,800 | Long runs, premium controls |
Assumptions: Midrange regional labor, standard attic access, typical home layout, and no unusual code complications.
