Reviews of Frigidaire FAH12ER2T 12,000-BTU Through-the-Wall Air Conditioner

Customer Ratings:

I recently moved to a Co-op Complex that has Emerson in the wall units. This unit is easy to install (but very heavy), blows very cold air out and the remote is easy to use. It comes with the stuffer sealer and replacement sealer for inside the wall sleave. My living room is 12' wide and is approx. 36' long. The air circulates rather well and after having the A/C on for a little while, the temperature reader on the remote control did drop severl degrees. This was when we had a heat wave of 93 degrees or higher for several days in a row. It defiantly is powerful, I had the bathroom door closed and it was hot in there while the living room was noticably cooler than earlier. For 12,000 BTU the energy rating was not bad at 9.0 but its not an energy star model. Still, it was much better than the 20 year old A/C that it replaced. I believe the other model that was less than 12,000 BTU had an energy efficiency rating of 9.4 which my maintence guy said isn't really noticable and the new Frigidaire 12,000 BTU model is much better at energy efficiency than the old Emerson that I replaced it with. Still when I replace the other 2 Emerson A/C's I think I'll stick with Frigidaire.

This unit is great! My electric bill is not making me twist my head like from The Exorcist. I just bought its middle sibling, the 10,000 BTU unit for my bedroom and its great. My bill only slightly went up a few dollars but that was it. Last year when I had the Emersons going, the bill was constantly over $70. I got the 10,000 BTU A/C for $350 from PCR. The 12,000 BTU A/C from the same place was about $410 last year. Frigidaire and LG are the only products that we buy. (major appliances)

This unit is so expensive to operate and sent our electric bills through the roof!! We hardly ever turn it on now, because we can't afford it and wish that we had never bought it.

I am quite pleased with my through the wall AC/Heater. I purchased this for my "Man Cave" that is a 16 x 32 x10' room attached to my new garage. I will use this to cool it on the humid summer day's and to supplement my pellet stove for heat in the winter if needed. Using the wall sleeve kit installation was a breeze.

As for cost to operate etc. we will have to wait and see.

For a 12000 BTU unit there are some givens: it's going to be heavy, it's will raise your electric bill some to have it running, and it's going to make a little noise. If you can live with those things, this is a great unit.

You should know: this unit requires a single 20 amp, 230 V outlet #10 or #12 wire from the outlet to the breaker. It should be on its own circuit breaker (2-pole breaker). Installation of the wall sleeve was challenging due to poorly written instructions, which caused me to take the heavy unit in and out of the sleeve a few times. Installation of the A/C unit itself is pretty straightforward: slide it into the wall sleeve, stuff insulation around gaps (also sprayed some Great Stuff for extra measure), slide in the edge trim, plug it in.

The room I installed this in is a 400 sq ft bonus room over our garage. We let the A/C run if we're actually in the room. The room never gets chilly, but the unit keeps it comfortable before installation it was uncomfortably hot. We watch TV or the kids play in this room. When the unit is on high fan we turn up the volume on the TV about 10 dB (a minor adjustment), and the fan is background white noise. Not enough to be bothersome, but this is by no means a silent unit.

The remote on this particular model doesn't have a temperature sensor. Great idea but you won't see it with this model. In the place of the "remote sensor" button is a button simply labeled "heat."

The unit has three control options: fan control, temperature control, and timer control. You can set the fan to low, medium, high or "Auto Temp," which means it automatically blows high until the desired temperature is reached, then it will switch to a lower fan setting. Lower fan speeds are quieter. The temperature options are cool, heat, fan only, and "Energy Saver," which the manual describes as: "In this mode, the fan will continue to run for 3 minutes after the compressor shuts off. The fan then cycles on for 2 minutes at 10 minute intervals until the room temperature is above the set temperature, at which time the unit cooling system starts again." The timer allows you to do a delayed start, a delayed stop, or sleep mode. Sleep mode will adjust the temperature (up in cool mode, down in heat mode) 2 degrees at a time every 30 minutes. After adjusting the temperature twice it will maintain the temperature for seven hours. We don't sleep in our bonus room, so you decide if that feature is useful to you.
