The Garvee 8,000 BTU Window AC with Heat is a 4-in-1 unit that works as an air conditioner, heater, dehumidifier and fan for rooms up to 350 square feet. It runs on standard 115V power and adds app control, Alexa support, a remote and a 24-hour timer. Among conventional window air conditioners, it is one of the few 115V heat and cool combos with smart control.
Garvee lists noise as low as 52 decibels. The main points to check are the 81.4 pound weight and the 16 inch window height. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This Garvee is a practical choice for an apartment, living room or bedroom that needs cooling in summer and supplemental heat in winter. Its strongest points are the heat and cool combo on a 115V outlet, 5 working modes (cool, heat, dehumidify, fan and auto), fan settings of auto, high, medium and low, ECO and sleep modes, a 24-hour timer, 4-way swing, app and Alexa control, and a clean filter alert.
The trade-offs are the heavy cabinet, no inverter and a listing that does not give the heating capacity. The heat is supplemental rather than a full heating system. If you want one smart window unit for both seasons in a room up to 350 square feet, it is worth considering.

Cooling Capacity and Room Size
Garvee rates this unit for rooms up to 350 square feet. It provides cooling and dehumidification in summer, supplemental heat in winter and a fan mode for air circulation in between.
Auto mode chooses the right setting to hold your set temperature, and the 4-way swing moves the louvers to spread airflow across the room. Dehumidify mode helps on humid days when the room feels sticky rather than hot.
For a living room or apartment near the top of the range, start on high to bring the temperature down, then let auto mode take over.
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 8,000 BTU, it lines up with rooms of about 300 to 350 square feet on the ENERGY STAR chart, which matches Garvee’s coverage claim. Remember to add 4,000 BTU if you plan to cool a kitchen.
Heating Performance
Garvee describes the heat as supplemental heating for winter. The listing does not give the heating capacity, so treat it as a way to take the chill off a room rather than the main heat source.
Heat mode works from the panel, the remote, the app or Alexa. Setting the temperature on your way home lets the room warm up before you arrive, and the 24-hour timer can do the same on a schedule.
Installation and Fit
The unit fits windows 16 inches tall and 26 to 36 inches wide. A quick and effective window mounting kit and detailed instructions are included. Garvee asks buyers to confirm their window size and voltage before ordering.
The cabinet measures 19.76 inches deep, 24.02 inches wide and 15.16 inches tall, and weighs 81.4 pounds. That is heavy for an 8,000 BTU unit, so plan for two people and make sure the sill and any support bracket can carry the load.
It runs on 115V/60Hz power, so a standard household outlet is enough. The listed wattage is 730 watts.
Noise, Energy Use and Efficiency
Garvee lists noise as low as 52 decibels, quiet enough to work, relax or watch TV without disturbance. Sleep mode adds a quieter setting for the night.
The listing does not give an efficiency rating such as CEER. The ECO energy saver mode and the programmable 24-hour timer are Garvee’s tools for reducing unnecessary power use. There is no inverter compressor.
Controls and Smart Features
All functions can be set from the control panel, the remote, the app or a voice assistant, and Garvee says it works with Alexa. You can set the temperature on your way home so the room is comfortable as soon as you arrive.
The digital LED display shows the current setting at a glance. The 24-hour timer covers routine scheduling without opening the app.
For a bedroom, a simple routine works well: cool or heat the room before bed, switch on sleep mode and set the timer to turn the unit off later in the night.
Maintenance and Drainage
The filter is washable, and the clean filter alert tells you when it needs attention. Slide it out, rinse it, let it dry fully and slide it back in. A clean filter keeps airflow steady for both cooling and heating.
The listing does not describe condensate drainage. Check the manual for how water is handled, especially in dehumidify mode, and for storage steps if you remove the unit for part of the year.
