"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.

"The owner Dave Tarrance was one of five companies that gave us estimates. Crawlspace Doctor had the best price for the work we wanted done. Dave listened to all our concerns about our crawlspace and offered solutions to help us resolve the issues. During the work he stopped in personally to keep us updated on the progress of the job, which took five days. His crew was very polite and disposed of all debris (old insulation) each night."

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."

CP has been providing quality home warranty products since 1998.

"The person performing the service had to make several trips because one of the "new" parts turned out to be faulty. I found both Complete Protection and their local repair contractor to be both very responsive and totally professional at every stage of the repair process."

Heating and Air Conditioning questions, answered by experts

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

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.

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.
