How can we help?
Top questions
What if the part doesn't fit?
Free return, full refund, and we'll help you find the right part — that's the fit guarantee. Start from your order page; there's no restocking fee on verified-fitment purchases.
Where's my model number?
On the rating plate — a metal or foil sticker inside the service panel on a furnace, or on the outside cabinet of an AC unit. It lists the model and serial together. Our rating-plate guide shows exactly where to look for each type of equipment.
How fast is trade-account approval?
Most trade applications clear within one business day. You'll need a business name, a resale or contractor licence number, and a trade reference. Once approved, your contract pricing applies automatically at checkout.
Orders & shipping
When will my order ship?
Order by 6pm ET and in-stock parts ship the same day. Ground is free over $99; 2-day and next-day are quoted live at checkout. You'll get the tracking number by email the moment the label is scanned.
How do I track my order?
The shipping confirmation email carries the tracking link, and the order page in your account shows the same timeline — placed, packed, shipped, delivered — with every carrier scan under it.
Can I change or cancel an order after placing it?
If it hasn't been picked yet, yes — contact us right away and we'll intercept it. Once a package is with the carrier we can't pull it back, but the fit guarantee still covers you: refuse delivery or start a return, either way you're not stuck with it.
Do you ship to job sites?
Yes — any US street address works, and pro accounts can save multiple job-site addresses with their own labels so the right parts hit the right truck. Will-call pickup at our Columbus counter is free.
Returns & fit guarantee
What if the part doesn't fit?
Free return, full refund, and we'll help you find the right part — that's the fit guarantee. Start from your order page; there's no restocking fee on verified-fitment purchases.
How do I start a return?
Open the order, choose Start a return, and print the prepaid label. Box the part in its original packaging where you can — carriers are hard on loose ceramic and electronics. Refunds go back to the original payment method.
How long do refunds take?
We refund within one business day of the part arriving back at our dock. Cards post in 3–5 business days depending on your bank, back to the original payment method.
Is there a warranty on parts?
Every part carries at least the manufacturer's warranty, and most of what we sell is covered for one year. Warranty claims and mis-fit returns are different processes — a part that failed in service goes through the warranty claim.
Fitment & parts help
Where's my model number?
On the rating plate — a metal or foil sticker inside the service panel on a furnace, or on the outside cabinet of an AC unit. It lists the model and serial together. Our rating-plate guide shows exactly where to look for each type of equipment.
How do I know a part fits my unit?
Enter your model number on any part page and we check it against the manufacturer's parts list plus our own verified cross-references. Green check means verified fit — and everything verified is covered by the fit guarantee.
My part number is discontinued. What now?
Most discontinued parts have a direct OEM-blessed replacement, and our cross-reference data maps the old number to the new one. Search the old number — if a replacement exists, the part page names it and links it.
Can you identify a part from a photo?
Yes — that's the photo-a-part service. Send a clear shot of the rating plate or the old part through the contact page and a tech will ID it, usually within the hour during chat hours.
Pro accounts
How fast is trade-account approval?
Most trade applications clear within one business day. You'll need a business name, a resale or contractor licence number, and a trade reference. Once approved, your contract pricing applies automatically at checkout.
What do the pricing tiers mean?
Tier pricing is volume-based: the more your account buys over a rolling year, the deeper the standing discount on every SKU. Your account page shows the current tier, the discount, and exactly how far the next tier is.
How do trade accounts pay?
Trade accounts pay by card at checkout, the same as retail — your contract pricing and any tax exemption apply automatically. You can tag each order to a job so it's easy to find and reorder later.
