Sales Tax & Shipping

Do you charge sales tax?

We collect sales taxes for select US states. If you see a tax amount listed on the last checkout screen and have a valid Tax Exempt Form or Resale Certificate for the ship-to state, we can add it to your account to make sure we do not collect state tax on your purchases. Give us a call or email prior to ordering or just place the order and we will remove the tax prior to shipping your order.

If you have previously placed your order online, please email the tax exempt form to The tax exempt form(s) must be received within 30 days of order. All received tax forms are verified with the corresponding state tax authority.

Most items we sell are shipped via UPS. ALL ITEMS SHIP FULLY INSURED AGAINST FREIGHT DAMAGE. Large items (such as commerical fans and large HRVs) must be shipped via truck freight. However, we are happy to make any arrangements that are required.

To view your final shipping cost, add the item(s) to your basket/cart and select the ship-to state. There is no need to enter any persnal information or to log in to see the shipping costs.

To determine transit time see the ship time maps on the individual product pages or give us a call. We ship from multiple warehouses.
