The Zehnder Novus 300 price and total install cost typically range widely depending on whether buyers purchase the unit only or a full ERV/installation package. Homeowners should expect a unit-only price plus contractor labor, ducting, and controls to drive the final price. This article lists realistic low–average–high figures and the main factors that change the estimate.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Zehnder Novus 300 Unit Only | $1,000 | $1,600 | $2,400 | Assumptions: new unit shipped, no controls, standard warranty. |
| Typical Professional Installation (complete) | $2,400 | $4,500 | $8,500 | Assumptions: 2,000 sq ft home, 2–4 supply/return runs, typical access. |
| Replacement (swap, minimal duct) | $900 | $1,800 | $3,800 | Assumptions: same footprint, existing compatible ductwork. |
| Annual Maintenance / Filter | $40 | $120 | $300 | Assumptions: filters, inspection, no major repairs. |
Typical Total Price Homeowners Pay For A Zehnder Novus 300 Installed
Most buyers pay between $2,400 and $6,000 for a Zehnder Novus 300 fully installed in a typical U.S. single-family home.
Unit-only purchases run about $1,000-$2,400 depending on dealer, options, and local shipping. Installed totals add labor, ductwork, controls, and any electrical or mounting work. The average installed scenario below assumes a 1,800–2,500 sq ft home with 2–4 duct runs and moderate attic/basement access.
| Scenario | Total Price | Includes |
|---|---|---|
| Unit Only | $1,000-$2,400 | Unit, basic mounting brackets, no install labor |
| Standard Install | $2,400-$5,500 | Unit, duct runs, balancing, hookup, basic controls |
| Complex Install | $5,500-$8,500 | Additional trunking, ceiling drops, new electrical, multiple zones |
Breakdown Of Major Quote Parts: Materials, Labor, Equipment, Permits
Expect the unit to be 25–45% of the installed price; labor and duct materials make up the remainder.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $400-$1,200 (duct, fittings, filters) | $900-$3,000 ( — see labor block) | $150-$600 (mounting, vibration isolators) | $0-$300 (local mechanical permits) | $50-$250 (old unit pickup, packaging disposal) |
How Size, Airflow (CFM), And Duct Runs Affect The Final Price
Airflow capacity and the number of trunk/branch runs are the strongest variables: every extra 20–30 linear feet of duct or each additional supply/return adds $200–$600.
Typical thresholds: 1) Homes under 1,200 sq ft (approx. 100–200 CFM) often need 2–3 runs and add $0-$1,200 over unit cost. 2) Homes 2,500+ sq ft (200–350 CFM) require larger trunking and balancing and can add $1,500–$4,000. Electrical upgrades or long runs (>50 ft) can add $300–$1,200.
Labor Time, Crew Size, And Typical Hourly Rates For Installation
Install jobs generally take 4–20 hours and cost $75–$125 per hour per qualified HVAC/ventilation contractor.
A small swap (unit-to-unit) is commonly 4–8 hours with a single tech. New installs with custom ductwork typically require 2 technicians for 8–20 hours. Add-on trades (electrician, drywall repair) increase total hours and may be charged separately.
Concrete Cost Drivers: Controls, Heat Recovery Options, And Accessories
Optional electronic controls, frost protection kits, or a heat recovery coil raise the price by $200–$1,200 depending on complexity.
Examples: upgraded wall control or zoning adds $200-$600; electric preheat or defrost kits add $400-$1,200; higher-efficiency filters or MERV 13+ cartridges add $40-$150 annually.
Three Real-World Quote Examples With Specs And Totals
Sample quotes help translate per-unit numbers into real projects.
| Example | Specs | Labor Hours | Total |
|---|---|---|---|
| Budget Swap | Novus 300, same footprint, attic access, 2 runs | 6 hrs | $900-$1,800 |
| Typical Install | Novus 300, 2,000 sq ft, 3 trunk runs, basic controls | 12 hrs | $3,000-$5,000 |
| High-End Remodel | Novus 300, new ductwork, 6 runs, preheat coil, zoning | 20 hrs+ | $6,000-$8,500 |
Practical Ways To Reduce The Zehnder Novus 300 Price
Control the scope: keep existing branch ducts, schedule off-season installs, and choose standard controls to lower costs.
Specific tactics: 1) Buy unit through the installing contractor to avoid markup but compare quotes. 2) Retain existing main trunk if compatible to save $500–$2,000. 3) Schedule installation in late spring or fall to avoid peak HVAC season labor premiums. 4) Opt for mid-grade filters rather than premium cartridges if budget constrained; upgrade later.
Common Extra Fees, Permits, And Maintenance Costs To Budget For
Budget an extra 5–15% of install cost for permits, minor electrical work, and post-install balancing.
Permit and inspection fees vary by jurisdiction ($0–$300). Expect routine maintenance (filters, simple cleaning) of $40–$120 per year; professional service/cleaning every 3–5 years can run $150–$400.
