"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for.

Appliancezone.com is a leading on-line retailer of appliance parts and accessories for do-it-yourself homeowners. Incorporated in 2008, it was started by CEO, Jim Allen and his wife Paula, who operated an appliance repair business for nearly fourteen years prior to starting the internet company Appliance Zone.

"This is the first online review I've ever written -- my experience with this company was that bad. Three aspects that deserve attention: 1) I placed an order and tried to cancel six minutes later. Turns out they don't accept cancellations. 2) I couldn't find a phone number, so I had to work the return/refund by email. The exchange was painful -- so unhelpful I felt like I was interacting with a bad chatbot. 3) I ended up eating shipping costs (expected) and got hit for a 50% restocking fee (unexpected) because I refused the package instead of paying to ship it back. Didn't matter that it went to the correct address, was clearly labeled, and had prior return authorization. So I ended up with a $21 refund on a $60 order, and a lesson learned about where not to buy appliance parts."

"You should probably add 4-6 weeks to the expected delivery date if you expect to need the "enclosed" hardware. I received the blinds in the estimated time, but it came without the required hardware. I have made 4 calls (at least) over several weeks, but the hardware is nowhere in site. It is clear that SelectBlinds.com is a marketing company only has outsourced all production and fulfillment to third parties and evidently has a difficult time coordinating these type of customer service issue. Extremely frustrating that my blinds have been sitting in the floor for over a month and all I need is a few screws. Happy to go to Home Depot to get the screws, but SelectBlinds can't even tell me what sizes I need."

RepairClinic.com® makes fixing things easy for millions of people. Founded in 1999, it is North America’s trusted online store with replacement parts for major household appliances, outdoor power equipment and heating and cooling equipment.

In-stock parts are guaranteed to ship the same business day. Visit RepairClinic.com for more information.

"Repair Clinic sent me a water intake valve that had some scuff marks and an unnecessary fixture (which I thought nothing of, assuming it had been removed from a new dishwasher). When the part did not fix my dishwasher's issue, I ordered a circulation pump, which also failed to fix the issue, so I decided to return both parts. Repair Clinic blamed me for the scuff marks and extra fixture, which is unacceptable. They referenced their return policy which states that parts which have been installed cannot be returned, and denied me any form of refund. For all I know, the water intake valve was defective, and I have no recourse. Don't put any stock in the "No-Hassle 365-Day Returns" they proudly tout on their homepage. Instead, expect finger-pointing and uncaring dismissal. You are better off with one of their many competitors."

Heating and Air Conditioning questions, answered by experts

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
