The LG 18,000 BTU model is sized for larger rooms — cooling up to 1,000 sq. ft. It provides supplemental heating and requires a 230/208V LCDI plug (NEMA 6‑20) for operation, which is typical for higher‑capacity window units.
Features include digital controls, remote, 4‑way air deflection, and a 24‑hour timer. Two speeds for cooling and heating offer basic customization while a filter light reminder and removable washable filter aid maintenance. The supplemental heat mode is intended for temperate conditions as an assist to primary heating.
This unit suits larger open living areas or basement installations where a higher BTU capacity and broader airflow control are needed. The 230/208V requirement should be verified before purchase to ensure compatibility.
ROVSUN 8,000 BTU Window Air Conditioner With Heat
ROVSUN’s 8,000 BTU window AC/heat combo lists cooling at 8,000 BTU and heating at 4,000 BTU, targeting rooms up to 350 sq. ft. It offers five modes (Heat, Auto, Cool, Dry, Fan), three fan speeds, and an ECO energy saver mode.
Smart features include app connectivity and voice control with Alexa/Google Assistant, enabling remote scheduling and routines. The unit has a front‑accessible washable filter and a swing setting to adjust louver direction.

This model highlights convenience through smart integrations and multiple modes. The stated heating BTU is lower than cooling, indicating it is best used for mild supplemental warming rather than as a primary heater in cold climates.
GE AWGP08WWA 8,000 BTU Smart Heat/Cool Window Unit
The GE 8,000 BTU smart window unit uses advanced heat pump technology to improve heating efficiency versus typical electric resistance heat. It covers medium rooms up to 350 sq. ft. and offers both remote operation and Wi‑Fi control via a companion app.
Key points include equal cooling and heating BTU ratings, enabling more consistent year‑round performance, and the option to control temperature remotely. The unit is positioned for bedrooms and living spaces where smart scheduling and efficient heating are important.
Heat pump efficiency can deliver faster, more energy‑efficient warmth than resistive supplemental heaters, but performance is subject to outdoor temperature constraints typical of heat pump systems.
Whirlpool 18,000 BTU Window Air Conditioner With Supplemental Heat
Whirlpool’s 18,000 BTU window unit targets large rooms up to 1,000 sq. ft. It offers significant cooling capacity with supplemental heating designed to assist—but not replace—primary heating systems in very cold weather.
The unit includes 3 cooling speeds, digital controls, eco and sleep modes, a programmable 24‑hour timer, and 8‑way directional louvers for targeted airflow. A quick‑install mounting kit is supplied to simplify installation in compatible windows.
This model fits larger living rooms or multi‑use spaces where strong cooling is required and supplemental heat can provide seasonal comfort during milder cold periods. Verify window height and electrical requirements prior to purchase.
Buying Guide: Choose The Right Window AC Heater Combo
Selecting the best window air conditioner with heat depends on multiple factors. Below are the critical considerations and comparison perspectives to help match features to your needs.
Room Size And BTU Requirements
- Measure Room Area: Calculate square footage (length × width). Use manufacturer coverage as a guideline: ~8,000 BTU for 250–350 sq. ft., ~18,000 BTU for 800–1,000 sq. ft., larger units for greater areas.
- Avoid Oversizing: Excess capacity can short‑cycle, reducing dehumidification and comfort. Slightly larger units help in poorly insulated rooms or rooms with high ceilings.
Heating Type And Performance
- Heat Pump vs. Supplemental Heat: Heat pump units move heat and are more energy‑efficient than resistive supplemental heating, but they lose efficiency at very low outdoor temperatures.
- Heating BTU Ratings: Compare heating BTU to cooling BTU. Units with similar heating and cooling BTU (e.g., 8,000/8,000) provide more balanced year‑round performance.
- Intended Use: For primary heating needs in cold climates, a dedicated heating system is recommended; window units are typically supplemental.
Electrical Requirements
- Voltage And Plug Type: Higher BTU units often require 230/208V and specific plugs (NEMA 6‑20). Confirm your home’s outlet and circuit capacity.
- Circuit Load: Ensure the circuit can handle the unit’s current draw; high BTU units may need dedicated circuits.
Energy Efficiency And Operating Cost
- Energy Star & Inverter Tech: Look for inverter compressors and Energy Star ratings to reduce runtime and electricity consumption.
- Modes And Fan Speeds: Eco, sleep, and variable fan speeds help manage energy use and maintain comfort.
Noise, Installation, And Maintenance
- Sound Levels: Bedroom installations benefit from quieter models and inverter compressors that run at lower RPMs.
- Installation Type: Confirm window size, minimum height, and whether a through‑wall or 230V unit is required for your location.
- Filter Access: Front‑accessible, washable filters simplify maintenance and help air quality.
Smart Features And Controls
- Remote And App Control: Wi‑Fi and app control allow scheduling, remote temperature adjustments, and integration with smart assistants.
- Thermostat Accuracy: Units with room‑sensing remotes or built‑in thermostats provide better local temperature control.
Durability And Warranty
- Brand Support: Consider manufacturer reputation, availability of replacement parts, and warranty coverage.
- Seasonal Use: Window units exposed to outdoor conditions benefit from periodic inspection and timely filter cleaning.
Comparison Perspectives
- Small To Medium Rooms: 8,000 BTU smart heat/cool units (Midea, GE, ROVSUN) balance efficiency, smart features, and quiet operation.
- Large Rooms: 18,000 BTU units (LG, Whirlpool) deliver stronger cooling for open floor plans but often require 230/208V and careful installation.
- Smart Home Integration: Units with Wi‑Fi and Alexa/Google compatibility support remote management and routines.
- Energy Savings: Inverter and Energy Star units reduce operating cost for frequent year‑round use.
Use the above factors to prioritize what matters most: cooling capacity, heating type, electrical compatibility, smart controls, or noise. Matching a unit’s BTU and heating method to your climate and room size will maximize comfort and efficiency.
