Typical Zehnder ComfoAir 350 Price For a 2,000 sq ft Home
For a typical U.S. 2,000 sq ft single-family home the total Zehnder ComfoAir 350 installed price is usually $3,800-$7,200. Assumptions: single-story or simple two-story plan, 6-8 supply/return vents, moderate attic access.
Expect the unit alone to cost $1,300-$2,500 and installation plus moderate ducts to add $2,000-$5,000.
Breakdown of Unit, Ductwork, Labor, and Permits
| Materials | Labor | Equipment | Permits |
|---|---|---|---|
| $1,300-$2,500 (unit) + $300-$1,200 (filters, controls) | $900-$3,500 (installation labor) | $200-$900 (mounting, core drill, fans/tools) | $0-$500 (local HVAC/electrical) |
Assumptions: Midwest labor rates, basic electrical hookup, standard duct materials.
Materials and labor typically make up roughly 60–80% of the installed price; permit and equipment fees are smaller but can push a quote higher in strict jurisdictions.
How Home Size, CFM Demand, and Duct Runs Change Quotes
System sizing and airflow needs directly change the price: the ComfoAir 350 is rated for about 350 m3/h (~205 CFM) continuous; homes needing higher CFM require multiple units or higher-capacity models. Thresholds: up to 1,200 sq ft usually fits one unit; 1,200–2,500 sq ft may need 1–2 units or extended ducting; over 2,500 sq ft likely requires alternate model.

Adding each extra 50–100 linear feet of duct or an additional 50 CFM requirement can add $300-$1,200 to the total quote.
Practical Ways To Reduce Zehnder ComfoAir 350 Price
Control scope: use existing duct paths, minimize long bespoke duct runs, opt for contractor-supplied standard grilles rather than custom finishes, and schedule installation off-peak. Tip: bundling electrical hookup and ventilation with other planned trades reduces mobilization fees.
Doing pre-install prep (clearing attic access, marking registers, providing an electrical circuit) typically saves $200-$800 on labor charges.
Regional Price Differences Across U.S. Markets
| Region | Installed Low | Installed Average | Installed High |
|---|---|---|---|
| Midwest | $3,200 | $5,500 | $8,000 |
| Northeast | $3,800 | $6,200 | $9,500 |
| West (CA/WA) | $4,000 | $6,800 | $10,500 |
| South | $3,000 | $5,300 | $8,500 |
Assumptions: regional labor rates, permit costs, and shipping; percentages vary ±10–30%.
Expect coastal metro areas to be roughly 15–35% higher than Midwest baseline due to labor and permit costs.
Installation Time, Crew Size, and Typical Labor Rates
Installation time is commonly 6–16 hours for a straightforward job; complex multi-level ducting can take 2–3 days. Typical crew: two technicians. Typical labor rates: $75-$125 per hour for HVAC contractor labor.

A standard 10-hour job at $95/hour with two techs often yields $950-$1,900 in labor on the final invoice depending on billed crew hours.
Real Quote Examples With Specs, Labor Hours, and Totals
| Example | Specs | Labor | Materials | Total |
|---|---|---|---|---|
| Basic Install | 1 unit, 6 vents, 40 lf ducts | 8 hrs × $85 = $680 | $1,600 (unit+filters+duct) | $2,380 |
| Moderate | 1 unit, 8 vents, 80 lf ducts, balancing | 12 hrs × $95 = $1,140 | $2,500 | $3,640 |
| Complex | 1 unit + transfer fans, 12 vents, 150 lf ducts | 24 hrs × $110 = $2,640 | $4,200 | $6,840 |
Assumptions: quoted labor includes travel; materials include basic electrical and grilles but not structural modification.
Comparing at least three written quotes that list unit, ducting, labor hours, and balancing makes it straightforward to identify where costs differ.
