"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.

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."

Heating and Air Conditioning questions, answered by experts

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money. 

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

No, a licensed local AC repair technician must replace AC coils due to the need to handle hazardous refrigerants. Attempting DIY poses risks to your personal safety, as most refrigerants are flammable and toxic. You also risk voiding your warranty with the HVAC company and causing damage to the unit.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
