| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Unit Only | $2,200 | $3,200 | $4,200 | Manufacturer MSRP, no freight |
| Installed System | $4,500 | $7,500 | $10,500 | Includes basic ducting, labor, and startup |

Total Installed Price for a Zehnder ComfoAir Q350
The typical installed price for a ComfoAir Q350 in a single-family U.S. home ranges from $4,500-$10,500, with an average around $7,500. Most homeowners see a mid-range total when replacing an existing ERV or installing into an attic or mechanical room with standard duct runs.
Assumptions: 1,500–2,500 sq ft home, 8–12 outlet registers, normal access, Midwest labor rates.
Breakdown of Materials, Labor, Equipment, and Permits
This breakdown reflects what contractors include on quotes for a ComfoAir Q350 installation; numbers are ranges for each line item. Understanding component-level pricing helps buyers compare quotes and spot inflated line items.
| Materials | Labor | Equipment | Permits |
|---|---|---|---|
| $800-$3,500 (ducts, elbows, grilles, filters) | $1,200-$3,500 | $2,200-$4,200 (unit, controls) | $100-$1,200 |
| Includes flexible or spiral metal duct options | (10-40 hours, $75-$125 per hour) | Includes optional balancing dampers, heat recovery elements | Depends on jurisdiction and required testing |
How Home Size, Duct Length, and Filter Class Change Price
Final quotes depend heavily on three measurable variables: conditioned floor area, total duct linear footage, and filter MERV rating. For each additional 500 sq ft above 2,000 sq ft expect $400-$900 extra for ductwork and labor.
Long duct runs add costs: runs over 50 linear feet typically add $300-$1,200; complex routing or multiple levels adds more. Higher-grade filters (MERV 13+) add $50-$200 to initial material costs and slightly higher ongoing filter costs.
Actions Homeowners Can Take To Lower ComfoAir Q350 Price
Buyers can reduce cost by simplifying scope, choosing standard ducting, scheduling off-season installs, and preparing the site. Removing old equipment, clearing attic access, and pre-marking register locations can save contractors 2–6 labor hours.
Other cost controls: accept manufacturer standard controls, avoid unnecessary premium grilles, and bundle ERV install with related HVAC work to reduce mobilization fees.
How Prices Vary Across U.S. Regions and Climate Zones
Regional labor and shipping change the installed price by roughly +/-15–30%. Expect prices ~15% higher in the Northeast and West Coast metro areas and ~10–20% lower in parts of the Midwest and South.
Climate impacts sizing: cold-climate projects may add defrost or frost protection options ($150-$600) which increases both unit cost and complexity of controls.
Typical Installation Time, Crew Size, and Labor Rates
Most ComfoAir Q350 installs take 10–30 hours and require a 1–2 person HVAC/ERV crew; larger homes or complex duct paths may need a 3-person crew or multiple days. Budget labor rates of $75-$125 per hour and expect total labor charges of $1,200-$3,500.
Permitting and testing add scheduling time—plan 1–3 weeks for permit approval and 1 day for commissioning and balancing once installed.
Common Add‑Ons, Disposal Fees, and Replacement Parts That Raise the Quote
Quotes often include optional items that increase totals: full duct replacement ($1,500-$4,000), electrical upgrades ($200-$800), condensate or drain modifications ($150-$600). Disposal of an old HRV/ERV and minor demo typically adds $75-$350.
Warranty extensions, specialized controls, and duct sealing to NADCA standards add $200-$1,200 depending on scope and contractor guarantees.
