"My chest freezer broke down and I did not want to buy a new one since I could not afford the same size. I reached out to appliance parts pro and they were confident that what I ordered would fix my problem. $200 in parts later and I now have a broken freezer on my porch and am still paying the loan to this terrible company. They just want you to order parts and try them because they know you can't return them. I hate this company with every fiber of my being and will make sure that anyone that has a broken appliance will not use them. To top it off, their site is so screwed up that it give you an error trying to log back in. I ended up having to create THREE different accounts because every time I went to place a new order, it would not let me login and it would not send a password reset email. DON'T GET RIPPED OFF."

"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."

"You should probably add 4-6 weeks to the expected delivery date if you expect to need the "enclosed" hardware. I received the blinds in the estimated time, but it came without the required hardware. I have made 4 calls (at least) over several weeks, but the hardware is nowhere in site. It is clear that SelectBlinds.com is a marketing company only has outsourced all production and fulfillment to third parties and evidently has a difficult time coordinating these type of customer service issue. Extremely frustrating that my blinds have been sitting in the floor for over a month and all I need is a few screws. Happy to go to Home Depot to get the screws, but SelectBlinds can't even tell me what sizes I need."

Heating and Air Conditioning questions, answered by experts

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling.

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

HVAC systems last around 10 to 30 years. If you complete the recommended maintenance, you can expect your system to reach its maximum life span. The life span also depends on the type of HVAC system. Heat pumps last about 10 to 15 years, AC units last about 15 to 20 years, and furnaces last around 15 to 30 years. Boilers have the longest life span, as they last around 20 to 30 years.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

Turning off your AC may temporarily stop your unit from leaking water unless the leak is from a thawing coil that continues to thaw after the system is shut off. Regardless, it helps to discontinue use of the unit if it has a leak in order to figure out what’s causing the issue.
