If you're researching a Tamarack whole house fan for your home, you'll want to understand the differences between their various models before making a purchase.
Each Tamarack fan comes with different CFM ratings, R-values, and installation requirements, and choosing the right one depends on your home's square footage, ceiling type, and climate. Getting this decision right means better performance and real energy savings on your monthly bills.
In this guide, we break down Tamarack's current whole house fan lineup with detailed specs, pricing information, and sizing recommendations.

1. WholeHouseFan.com Tamarack whole house fans
WholeHouseFan.com carries the complete Tamarack HV lineup as an authorized retailer, giving you direct access to genuine factory products with full manufacturer warranties. Their inventory includes four main R38 insulated models that range from 1,000 CFM to 3,400 CFM, each designed for different home sizes and cooling needs.
Key specs to compare before you buy
You'll want to compare CFM ratings, R-value insulation, and motor power across Tamarack models before deciding which fan fits your home. The HV lineup shares a consistent R38 insulation rating, which minimizes heat loss in winter and keeps conditioned air inside during summer. Motor specifications differ by model, with larger units requiring more powerful motors and increased electrical capacity to move higher volumes of air through your attic space.
CFM ratings directly correlate to the square footage your fan can cool effectively, making this the most important spec to match with your home size.
Sound levels matter too, as Tamarack fans operate between 40 and 52 decibels depending on the model and speed setting. Weight and physical dimensions vary significantly across the range, affecting both installation complexity and attic space requirements for proper clearance.
Sizing guidance and model matching
Match your home's total square footage to the appropriate CFM rating when selecting a Tamarack model. The HV1000 handles homes up to 1,500 square feet, while the HV3400 effectively cools spaces reaching 5,000 square feet or more. Your ceiling height and attic ventilation capacity also influence which model works best, since inadequate attic venting can bottleneck even the most powerful fan.
Typical price range and what affects cost
Tamarack whole house fan prices at WholeHouseFan.com run from approximately $800 to $1,600 depending on the model you choose. The HV1000 sits at the lower end of the range, while the HV3400 represents the highest investment due to its increased motor size and airflow capacity.
Where to buy, shipping, and support basics
WholeHouseFan.com ships Tamarack fans directly to your door with fast processing times and provides free lifetime customer support for every purchase. You get a 60-day money-back guarantee with no restocking fees, letting you install and test your Tamarack whole house fan risk-free.

Sizing guidance and model matching
