The Electactic 10,000 BTU Window AC is a 115V unit for living areas, bedrooms and offices up to 450 square feet. It combines cooling with dehumidification, three fan speeds and Sleep, Auto and Eco modes, plus a programmable timer. It is a newer brand among mid-size conventional window air conditioners, with 4.3 stars from 557 ratings.
It suits a living room or large bedroom. The main gaps are missing window fit details in the listing. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This Electactic is a well-rounded unit for a medium to large room. Its strongest points are a listed CEER of 10.9, three fan speeds, dehumidification, Sleep, Auto and Eco modes, a programmable timer from 0.5 to 24 hours, a washable filter with a reminder light, automatic restart after power interruptions and a complete window mounting kit. The listed noise level is 51 dB.
The trade-offs are gaps in the listing. It does not give a window opening range, and the listed dimensions look inconsistent, so confirm the fit before ordering. There is no inverter or Wi-Fi. If you want a straightforward, efficient unit for a room up to 450 square feet, it is worth considering.

Cooling Capacity and Room Size
Electactic rates the unit at 10,000 BTU for spaces up to 450 square feet and names living areas, bedrooms and offices. That covers most apartment living rooms and large primary bedrooms.
Effective dehumidification adds comfort in humid weather. If your room is well under 400 square feet, a smaller unit may be a better match, since an oversized AC cools quickly and shuts off before removing much moisture.
The three fan speeds let you balance cooling speed and noise. Use the highest speed to bring a hot living room down after a warm afternoon, then step down once the room is comfortable.
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Adjust for your room: reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
At its listed 10,000 BTU, it lines up with rooms of about 400 to 450 square feet, which matches Electactic’s coverage claim.
Installation and Fit
The included window mounting kit and manual cover installation, and Electactic says you just follow the instructions, plug the unit in and start cooling. The listing does not give a window opening range, so check the manual or contact the seller for supported dimensions before ordering.
The listed dimensions appear to have the width and height swapped, so do not rely on them for fit planning. The unit weighs 48.7 pounds, so plan on two people. Follow the manual, secure the unit with the supplied kit and plug it into a standard 115V outlet.
Noise, Energy Use and Efficiency
The listed noise level is 51 dB, which is quiet for a 10,000 BTU unit and suitable for a bedroom on lower settings.
Electactic lists a CEER of 10.9, the standard efficiency rating for room air conditioners. Eco mode and the programmable timer help limit energy use. The compressor has no inverter, so it cycles on and off.
Controls and Smart Features
You can choose Sleep, Auto or Eco modes and set the programmable timer anywhere from 0.5 to 24 hours to match your schedule. Three fan speeds let you balance cooling and noise. The listing lists remote control.
Automatic restart returns the unit to its preset temperature after a power interruption or accidental shut-off. There is no Wi-Fi or app control.
The flexible timer is useful in a living room. You can set a short timer to switch the unit off after you go to bed, or a longer one to have it start before you get home.
Auto mode lets the unit choose settings to hold your target temperature, which is useful during the day when the room’s heat load changes. Eco mode is the better choice when you want to keep running costs down.
Maintenance and Drainage
The washable, reusable filter has a reminder light that tells you when cleaning is due. Rinse it, let it dry and slide it back in to keep airflow and efficiency steady.
The unit dehumidifies as it cools. The listing does not describe condensate drainage, so check the manual for how water is handled and for seasonal storage.
