"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."

"One word to describe Holbrook Heating, INCOMPETENT!!! **STAY AWAY, UNLESS YOU WANT TO WASTE YOUR TIME, MONEY AND HAVE UNNECESSARY AGGRAVATION IN YOUR LIFE** I purchased an extended warranty with the company I bought my HVAC unit, and Holbrook Heating was their designated contractor to install and maintain. HVAC unit was installed on 12.4.19, the compressor had to be replaced 3 times in 3 years, which is UNHEARD of, and it still did not work!!! After the 2nd compressor went at end of June 2022, I was told from Holbrook, they no longer service my area, so I would have to contact the new service company. I had to pay $149 for service call. New service company said I needed a new compressor and freon as there is a big leak. I told them that is impossible as compressor was just replaced a year ago and freon replaced, that means this would be the 3rd compressor! When they heard that, they told me they did not want to get get involved in this mess as they've never heard of 2 compressors breaking down in 2 years in all the years they've been in business. They said it's clear there is something gravely wrong and Holbrook had to deal with it. That's when Holbrook said they would do me a favor, (wink wink) and replace for me. Because of their incompetence, I went without A/C basically this whole summer! They installed 3rd compressor and added more freon on 8.16.22, I specifically asked them if they fixed the leak, as I cannot go through this anymore, the tech said there was no leak, valves needed to be tightened (I had to pay for freon thats not covered under warranty). 3 months later not working again! Rather than come back to address issue in mid November, when I still had warranty, (heat was only blowing out warm, then turned to cold air) they placated me stating all was fine with unit as its more energy efficient now. In beginning of December compressor started making really loud noises again. When I called them on 12.12.22, I was told my extended warranty expired on 12.4.22!!! And now I would have to pay $250 for service call and $250 an hr after that, as again, THEY NO LONGER SERVICE MY AREA. I then asked to speak to Scott Rossen, the owner, as how could he charge me this amount when clearly there's something wrong!! I'm still waiting for a call back, I won't hold my breath! Since I was no longer under warranty, I called another HVAC person, the first thing he told me is I had a huge leak and my freon is pouring out again!!! This is the reason why the compressor kept on breaking down. The compressor would need to be replaced again if I didn't call the new HVAC company. Also the thermostat Holbrook replaced, was not compatible with my system, so that's why heat never came out hot, only warm, then turned to cold air. New HVAC person fixed leak and installed proper thermostat within 4 hrs that Holbrook couldn’t fix in 3 years!!!! I had to pay $2200 in total for this visit (freon, new thermostat and their time). In total I paid almost an additional $3,000 because of Holbrook's incompetence. I'm more annoyed over the unnecessary aggravation and the time I wasted on them. I purchased a new HVAC system so I wouldn't have issues, all I had were issues because of them ughhhh"

Heating and Air Conditioning questions, answered by experts

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

Replacing an evaporator coil costs around $1,350 on average. The coil itself, depending on the size and brand, can cost from $550 to $1,100. Professional labor averages about $700 total. Note that a license is required to work with refrigerants, so it’s necessary to have an AC pro complete this task.

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.
