Pricing
AC Direct advertises contractor wholesale prices and claims savings of 30% to 60% off local contractor pricing by eliminating middlemen. It also offers a Price Match Promise on qualifying products. This pricing model is a genuine strength for full-system buyers who want lower equipment costs.
PexUniverse describes its pricing as competitive and often significantly lower than local hardware stores or other online retailers. It runs special deals and occasional flash sales, and provides coupons and promo codes such as 5% off, $30 off orders of $500 or more, and $60 off, though promo codes cannot be stacked. For PEX-specific items in particular, PexUniverse can offer better prices.
Shipping
AC Direct offers free shipping on orders over $1,500, with commercial products excluded. Orders of $1,500 or less are subject to a $60 fee, except for ductwork materials, which receive a specific shipping quote. AC Direct ships to the 48 contiguous states only, not Alaska or Hawaii, via common carrier. Delivery times are currently running 3 to 10 business days, not including holidays or weekends, with special order items taking longer. The driver delivers freight to the tailgate of the truck, a lift gate can be requested for an additional charge, and the customer moves freight to its final location after offloading. All orders ship fully insured, and customers must inspect equipment at delivery and note any damage on the delivery receipt.
PexUniverse offers free FedEx Ground shipping on all orders over $99, valid for the lower 48 states only. Orders shipped via freight may carry additional surcharges. To qualify, orders must be placed before 3PM EST on a weekday, have matching billing and shipping addresses, and contain in-stock products. Expedited shipping is free and automatically applied to qualifying orders. Orders placed on national holidays ship the following business day.
Returns
Both retailers publish return policies, so review the current terms on each site before buying.
AC Direct accepts equipment returns for 14 days from the date the customer receives them; later returns require manufacturer approval. A 15% restocking fee applies, based on the total order price plus associated insured freight to deliver and return materials. Equipment must be in like-new condition, uninstalled, undamaged, and returned in the original boxes neatly taped with clear tape, with all manufacturer documentation included. Original shipping charges are non-refundable, and for items that shipped with free shipping, the actual shipping cost is deducted. Refunds can take up to 3 weeks after AC Direct receives the return. Note that R410a equipment is no longer accepted for returns, and orders placed as of November 15, 2024 are not eligible for returns except for equipment shipped in error or damaged in shipping. Cancellations submitted in writing within one business day, before shipping, receive a 100% refund; after that a restocking fee may apply, and once shipped an order cannot be cancelled.
PexUniverse generally allows 30 days from the date of purchase to return items for a refund, with products required in original, unused condition with all packaging, accessories, and documentation. Custom-made or specially ordered items, and items that have been installed or used, are typically not returnable, and proof of purchase is usually required. Returns made between 30 and 60 days are subject to a 15% restocking fee. Some customers report delays in receiving refunds, and in some cases customers have been asked to pay return shipping on items shipped incorrectly or arrived damaged. A 3-day notification policy for damaged packages has been mentioned by customers. Confirm the current return policy on PexUniverse’s website before ordering.
Warranty and Support
AC Direct states that all equipment it sells includes a Manufacturer’s Warranty and recommends reading the full warranty included with the purchase, which can also be found on the manufacturer’s websites. AC Direct does not claim to provide its own warranty service, and for returns all manufacturer documentation, including warranty information, must be included. It says it cannot be held liable for installation or operation damages and will assist with shipping damage claims, though the carrier has final say.
PexUniverse highlights a knowledgeable customer service team that provides technical support, product recommendations, and help with project planning and design. Support is available by phone from 9:00 to 5:00 Monday through Friday and through its app, alongside installation guides, how-to articles, and expert tips. That said, the warranty claim process is a frequent point of contention, some users report receiving defective products, and support experiences are mixed. In some cases customers were told defective products were the manufacturer’s responsibility, contrary to website policy. Check PexUniverse’s current warranty terms before purchase.
