"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. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

"I called Marr's for an estimate for a new furnace/ac. Kyle came out and instantly impressed us with his expertise, thoroughness and friendly demeanor. He explained, in detail, the equipment we would need to have installed to maximize the comfort of our home. Well, we awarded the contract to Marr's. It was a large purchase for us and we were concerned about the quality of the job we would get...well those concerns were squelched almost immediately when Jacob and Wyatt showed up, on time, and well prepared to do the job. They were polite and respectful of our home. They are true professionals and performed the work to completion and to our complete satisfaction. Jacob took the time to go over the operation of the new programmable thermostat for the heating and cooling units. They left the work area in better condition than when they first arrived and the installed equipment looked great! I would recommend Marr's to anyone in a heart beat. Great job guys!!"

"The whole process was not pleasant. We went with Arrow because of the good reviews, but the insulation process was anything but easy. We have an older home that had nailed in dry wall. We decided to have the installation done through the home exterior in order to minimize clean up (we had a 3 month old at the time that we didnt want exposed to the dust/insulation particles). When the insulation was being blown in, many of our dry wall nails began to pop through the dry wall. We were never made aware of any of the potential problems with blowing in insulation through the home exterior, and this process created far more work than we were expecting. As for the exterior of our home, we were left with many siding boards damaged (which thankfully Arrow decided to pay for). Some of our siding could not get removed, and holes were instead cut into our siding. When these were initially patched, they looked awesome, but after only 1.5-2 months, the patch work began to show cracks, and now every hole that was created is visible from the street (some of the plugs have even been able to be moved around with very little pressure). This process has been a nightmare, and our home exterior, after almost 3 months, still is not what it was before the work was done."

2008 years of experience

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

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

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.

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.
