Rated 5 out of 5 by from Quite with a lot of great features We bought it for the air conditioner to begin with then a few nights later needed it for the heat. Worked beautifully. Love it!!

Rated 3 out of 5 by from I bought 2 units. Had to have a 220 volt outlet installed. Hooked up the first one and it cooled great. However the heat did not work. Replaced it with the second unit and both features work fine. I'm now working to get warranty service on the first unit and hopefully it will be resolved soon.

Rated 5 out of 5 by from Very efficient; great investment! This 12,000 BTU air conditioner/heater is just perfect for year-round comfort! I especially appreciate the Energy Saver. The thermostat allows me set a desired temperature -- and walk away! My unit accommodates a three-car garage and work shop. And still, it runs very little, once the atmosphere is reached. Excellent quality and attractive product. The remote is the cherry on top! Easy to use.

Rated 5 out of 5 by from Does the job. We have an unusual home consisting of several buildings, each with its own HVAC. This unit is in our den and cools it nicely in Econ mode. We will have to wait for cooler weather to see about the heat but are confident it will do well. Thanks.

Rated 4 out of 5 by from Great for the price I bought this to replace my 800 btu AC that I had in my bedroom. I went with the higher btu thinking that it would make my bedroom very cold. I like sleeping in the cold. It didn't make it any cooler then the smaller unit. It does work well. I like how a red light comes on the alert you when it's time to clean the air filter.

What gauge electric wire does the LW 1216HR air conditioner/heater require?

Asked by: Robert12
Wire is sold based on several factors. The most important part is the gauge, sometimes referred to as AWG (American Wire Gauge).The LG 12000 BTU Window Air Conditioner, Cooling & Heating, must be plugged into a standard 250 V, 3-wire grounding receptacle protected by a 20 Amp. time delay fuse or 20 Amp. circuit breaker. The amount of power that will be running over that line will require a 12 gauge wire. However, they are certain circumstances where a larger wire size may be needed even if the amp requirement does not seem to justify it. If your run is longer than 100 feet, inside a conduit or ganged with other wires where the heat dissipation may be inhibited, you may need to go to the next largest wire (10 gauge). According to the National Electrical Code, the overcurrent protection cannot exceed 20 amperes for 12 AWG copper. We strongly advise that you consult a professional with any questions about special circumstances...^IFV
