Shipping and Handling Information

Items are shipped Monday through Friday(excluding holidays) with a 3:00 p.m. cutoff time.

The majority of our orders are shipped with 24 hours of your payment clearing through paypal or your charge card.

It is your responsibility to keep your shipping address updated on eBay and PayPal. Should the package be returned to us as undeliverable due to an error in the address you have on file, additional shipping costs will be collected to compensate for reshipping the item to you.

Please note that our shipping process is quite efficient. We will attempt to process your address change, cancellation and order change as quickly as possible. However, we cannot guarantee that we will be able to provide this service. Often, an item is pulled, packed and shipped within minutes of our receiving the order. Please review your order for accuracy before submitting it.

USPS states on their website that their Express Mail service is a 1 or 2 day mail service. The time frame depends on your location and is determined by the Post Office. You may go to their website and click "Calculate a Price" to determine if your package will take one or two days to deliver.

Your will receive an email with the tracking # once your label is printed. Tracking information is accessible once the item is delivered to the post office or picked up by UPS.

When we are out of stock on an item, we may (at our discretion) choose to have the part shipped directly to you from our vendor. In these cases, the shipping carrier may change but we will attempt to have it delivered in the requested time frame. If we cannot keep to the original delivery time frame in these instances, we will notify you.

For our International Buyers

USPS First Class International mail is not trackable once it crosses the U.S. border. Delivery times vary by country and are not provided by the U.S. Postal System. Generally, our experience is that First Class International mail takes at least 3 weeks to deliver.

Canadian Customers: Please ask about using UPS Standard as your shipping option. If timely delivery and the ability to track your package is important, it is an option worth considering. However, UPS does charge brokerage and misc fees for Canadian shipments, so make sure you understand these fees before using UPS Standard as your shipping option.

If you desire the ability to track your package you will need to select either USPS Priority International, USPS Express Mail International or UPS as your shipping option.

Import duties, taxes and charges are not included in the item price or shipping charges and are the responsibility of the buyer.

Unfortunately, Customs may cause a delay in delivery of your item, please allow extra time for this process.

For Everybody!

Shipping charges include shipping fees, bubble wrap, other packing material, tape, transportation, carrier pickup fees, etc. These charges are not refundable for all correctly filled orders.

Return Policy

Customer satisfaction is very important to us.

However, you as the buyer play a very important part in this. Please review the entire listing carefully and make certain you are ordering the part you need. If you have any questions, please contact us before purchasing.

Full refunds are given only for a part this is grossly misrepresented by its picture or listing description, or if it is shipped incorrectly. Please note that HVAC manufacturers frequently update their parts without warning. While we strive to update our listing pictures as quickly as possible, an outdated picture is not grounds for return. If you receive a part updated by the manufacturer in the last 90 days, it will be considered as correctly shipped.

We have a 14 day return policy starting from date of delivery (confirmed by the carrier). You must obtain a return authorization to return the part within this time frame. We must receive the item being returned within 21 days of delivery date. Parts are not eligible for return for any reason if we are not notified within the 14 day time frame.

Damaged parts must be reported to us within 3 days of the delivery date. This is to insure that we can file a claim with the carrier when applicable. Please send an email describing the damage and attach pictures of the part and the packaging for our inspection.

A RMA # must be obtained prior to returning any part.

There is a 25% restocking fee on all parts that were shipped correctly (waived on exchanges)

All items being returned must be in their original packaging and accompanied by any instruction manuals and other paperwork. All items must be in a brand new (without signs of installation) and resaleable condition. All parts are inspected for signs of installation upon our receipt of them. (Note: Parts that have physical evidence of being installed may receive a 50% refund at our discretion. The decision is made based on our assessment of the part and whether it can be resold as "used". )

The customer is responsible for all return or replacement shipping charges including insurance. However, we will reimburse the return shipping charges (least expensive available) for incorrectly shipped items. Original shipping charges are not refundable unless the part was shipped incorrectly or damaged in transit. We recommend that the customer insures items being returned. Items being returned which are lost/damaged in transit are not the responsibility of the seller. However, we will assist in the buyer's efforts to file a claim with their carrier.
