About Windmill

Windmill is a consumer appliance brand focused on "modern air care," best known for its sleek, quiet, and app-connected window air conditioners, as well as complementary products like fans and air purifiers. Operated by The Air Lab, Inc. d/b/a Windmill, the company sells primarily online through its own website and major retailers, targeting customers who want more design-forward, energy-efficient alternatives to traditional window AC units and air quality devices.([windmillair.com](https://windmillair.com/?utm_source=openai))

A charge with a descriptor like "SP WINDMILL" or including the phone number +1-407-310-0607 is likely from purchasing a Windmill product online—most commonly a window air conditioner, an air purifier, a fan, or related accessories and filter subscriptions—from windmillair.com or a connected e-commerce checkout powered by Shopify (“SP” often denotes Shopify). It may represent a one-time purchase, a split or financed payment, sales tax and shipping, or a recurring filter-subscription charge if you opted into automatic filter deliveries at checkout. Authorization holds may also briefly appear when you first place an order or update your payment method.([shopabunda.com](https://www.shopabunda.com/products/windmill-smart-inverter-air-conditioner-with-whisper-tech-easy-to-install-ultra-quiet-window-air-conditioner-35-more-efficient-auto-dimming-led-display-app-and-voice-enabled-10-000-btu?utm_source=openai))

If you have questions about a Windmill charge, first check your email for order confirmations from Windmill and review your account or order history on windmillair.com. Match the charge amount and date with a recent appliance or accessory purchase, including any filter subscription you may have activated. If something doesn’t look right, you can contact Windmill support via the email or phone listed on their site and in their warranty and safety documentation; the support contact information and the +1-407-310-0607 number on the descriptor match the company’s official records, which is a good sign the charge is legitimate. If you still cannot recognize the transaction after checking your household’s purchases and subscriptions, reach out to your card issuer to dispute or block the charge while they investigate.([images.thdstatic.com](https://images.thdstatic.com/catalog/pdfImages/05/0579f941-9138-4354-87dd-95e0e72fdb98.pdf?utm_source=openai))

Frequently Asked Questions

Why do I see a charge from WINDMILL or SP WINDMILL on my card?

This charge is typically from purchasing a Windmill product—such as a window air conditioner, fan, air purifier, or accessory—through windmillair.com or a Shopify-powered checkout. The “SP” prefix usually indicates Shopify as the payment processor, while “WINDMILL” is the actual merchant name tied to The Air Lab, Inc. d/b/a Windmill.

What amounts are common for Windmill charges?

Windmill window AC units usually appear as larger one-time charges (often in the low- to mid-hundreds of dollars depending on BTU size and model), while smaller charges may be for accessories like filters, covers, or fans, or for recurring filter-subscription shipments. Sales tax and shipping can add to the total, so the final amount may be slightly higher than the base product price shown on the product page.

Does Windmill offer subscriptions that could cause recurring charges?

Yes. When you purchase certain products, especially window AC units or air purifiers, you can opt into recurring carbon or HEPA filter deliveries at a set interval. If you enrolled, you’ll see repeat charges around each shipment date. You can manage, pause, or cancel these subscriptions through your Windmill account or by contacting their support team.

How can I cancel or change my Windmill filter subscription to stop future charges?

Log into your account on windmillair.com using the email you used at checkout, then go to your subscriptions or order management section to adjust frequency, skip a shipment, or cancel. If you checked out as a guest or can’t access your account, reach out to Windmill support via the contact details on their website and provide your order number and the email tied to the purchase so they can locate and adjust the subscription for you.

How do I request a refund or return for a Windmill purchase I see on my statement?

Review Windmill’s Terms of Sale and warranty page on windmillair.com to confirm eligibility and return windows for your product, then locate your order confirmation email or order number. Contact Windmill via their support email or contact form with your order details, the reason for return, and photos if there’s a defect or damage. They will outline return shipping, refund timing, and any restocking or shipping fees that may apply.

Why does the descriptor include the phone number +1-407-310-0607?

Windmill’s safety and warranty documents and its app store listings list +1-407-310-0607 as a company contact number, and some card processors include this number in the transaction descriptor as a customer-service reference. Seeing this number next to WINDMILL generally indicates a legitimate charge from The Air Lab, Inc. d/b/a Windmill rather than a random unknown merchant.

Can Windmill place temporary or small pending charges on my card?

Yes. When you place an order or update your payment method, your bank may show a temporary authorization hold from Windmill (sometimes a small amount or a $0 test). These holds are used to verify your card and should drop off automatically within a few business days, leaving only the final settled purchase amount, if any.

How can I verify a Windmill charge before contacting my bank?

Start by searching your email for “Windmill” or “windmillair” to find order confirmations, then compare the posted amount and date to your orders, including filter subscriptions. Also check whether anyone else in your household ordered an AC unit, fan, or filters. If you still can’t match the charge, contact Windmill using the support information on windmillair.com and provide the last four digits of your card, charge date, and amount; they can usually look up the transaction. If they cannot locate it or you suspect fraud, contact your card issuer to dispute the charge.
