Frigidaire FFRE063ZA1 19″ Energy Star Window Mounted Air Conditioner with 6000 BTU Cooling Capacity With Remote 115V in White

I bought a 5000 btu Frigidaire last year (Model FFRA0511R1E) for the bedroom. It did an acceptable job of cooling an area larger than its rating (with the help of a tiny circulating fan), is not too loud, and draws only 3.5 amps, which is just amazing. My electric bills are tiny.

This year I added this model, a Frigidaire FFRE063ZA1 6000 btu, for the living room. It arrived with a small defect; the rail on the bottom to hold the left-side accordion wing was crushed at the end, and I had to bend the metal and shave the plastic frame of the wing in order to install the wing. Minor issue, not a difficult problem, but if I hadn’t been handy I would have had to send it back.

This unit is quiet, easy to set up and cools my studio apartment perfectly (a little over 350 square feet). I thought they’d forgotten to include hardware, but it’s packed with the gray foam insulation strip. I highly recommend this product.

I found only one flaw, but desided to give it5 Stars anyway. The one flaw is how the filter is clipped in when the air is on high it sometimes rattles. I added a bit of foam that came with it to the inside corner, and sound is gone. I love that for the price it came with all needed insulation for around the window. Something my old cheep fridgeair didn’t.

And this being only my 2nd unit I’m only judging it off the fridgeair.

Setting work great and the remote is great to have, When I can find it. but I’ll take that as user error. The rest of the house can be 79-80 and it will keep my room at 62.

Friedrich Chill Premier 6,000 BTU Smart Window Air Conditioner with Built-in WIFI

This Friedrich unit looks and works great – good controls on the unit. The remote control with LCD is OK, but I would opt for a simpler remote without the LCD screen, if one was available. The initial wi-fi setup is a little clumsy – you have to push a button on the remote 6 times within 6 seconds, and look for ‘CF’ to show up on the AC display. If you cannot get this to happen, or if the code comes up and then goes away, you need to unplug the unit, wait maybe 30 seconds, and then start again. Once the wifi and Frriedrich app are set up and configured, the app interface looks very good.

There is nothing not to like about this air conditioner. It’s easy to install, sturdy with impressive construction but I was able to install 2 of these units by myself. It cools off a room 250-350 square feet very well. The WiFi app is easy to use and awesome especially if you forgot to set the timer or you want to turn your a/c on remotely.

How to choose Window Air Conditioner?

Cooling: What great is a forced air system on the off chance that it can’t cool a room? This is our most significant test. I set the unit up in the test room, which is around 650 square feet. I place a thermometer on the furthest edge of the room. At that point, I have the climate control system run on high. I measure the temperature and dampness before I turn the unit on and contrast it with the readings after it’s been running for 60 minutes.

Uproar: You don’t need an AC unit to shield you from dozing, working, or staring at the TV so it needs to run discreetly. To test this, I utilized a sound meter situated six feet from the forced air system as it ran on high. I additionally alter the fan speeds and set point to check whether these progressions caused off-putting sounds that could frighten individuals close by.

Additional items: at least, a forced air system should accompany a window establishment pack, remote control, dehumidifier and fan modes, and deferred on and off. I likewise search for extra comforts, such as including froth to seal and protect the openings around the AC. WiFi-empowered savvy capacities are additionally a significant also, yet I discovered there’s a great deal of opportunity to get better here.

Vitality Efficiency: I take a gander at whether the unit is Energy Star-guaranteed just as the vitality productivity proportion (EER). The EER is the BTU isolated by the Watts. The joined vitality proficiency proportion (CEER) is additionally normally utilized. It thinks about the vitality utilization while a unit is in backup mode.

This is essential for holding down long haul utility expenses.

Establishment: Though establishment will probably just be a little piece of your relationship with your AC, it’s a significant part. Windows somewhere in the range of 27 and 36 inches wide will oblige most window units, yet on the off chance that you have a 25-inch-wide window, it gets uncertain. We take a gander at what windows various models fit. We likewise see to what extent it takes to introduce the ACs, on the off chance that you need extraordinary apparatuses, and how troublesome uninstalling and reinstalling it will be in the event that you live in an atmosphere where winterizing is an unquestionable requirement.
