"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.

We are a family owned/operated plumbing & HVAC company with over 25 years in the industry and a 2017 Super Service Award winner, offering residential and commercial services. We have focused on plumbing since establishment, but recently added HVAC services to our plumbing services and are offering the same level of expertise, care, and customer service that you have come to expect from our plumbing services. Kristina Johnson has 15 years’ plumbing office experience, but has been around plumbers all of her life. Her father, grandfather and uncle are all plumbers! It is probably no coincidence that she also married a plumber. Jerry Johnson has been a plumber for over 22 years. he is licensed through the State of Ilinois CCCDI (Cross Connection Control Device Inspector) and Med Gas Certified. Tina and Jerry have built on the family business and now run Complete Plumbing Services, Inc. in South Elgin, Illinois. We serve the Chicago Northern Suburbs, including Elgin, Bartlett, Schaumburg, St. Charles, Geneva, Elburn, Batavia and the entire Northern Illinois Region. We provide comprehensive services to our residential, commercial and industrial clients. When you call Complete Plumbing Services, it will probably be Tina who answers the phone. but no matter who answers, you can be assured that you will be speaking to someone who understands plumbing and HVAC services and we will be able to dispatch the help you need to get the job done–promptly and professionally.

"Nick called and said he could arrive early if convenient and that was perfect. He quickly identified the source of a leak in a drain pipe between a second floor bathroom and basement. In less than two hours he replaced a section of pipe in the wall that had been damaged by a nail. His work quality was excellent and was very efficient. I now prefer paying an hourly rate as opposed to most plumbing companies that charge by individual services that keep being added after the initial estimate."

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

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.
