Whirlpool 12,000 BTU Window Air Conditioner With Supplemental Heat
This Whirlpool window unit provides combined cooling and supplemental electric heating designed for spaces up to 550 sq. ft. The unit lists 12,000/11,600 BTU cooling and 11,000/9,000 BTU supplemental heat capacity, indicating it is intended to help maintain comfort during milder cold conditions rather than replace primary heating in severe winter.
Key controls include an electronic control panel with digital display, three cooling speeds, eco and sleep modes, and a 24-hour programmable timer. The package includes a quick window mounting kit for windows with minimum height of 19.5 inches, and 8-way directional louvers to adjust airflow direction.
Use cases: Good for apartment living rooms or larger bedrooms where supplemental heat is sufficient for transitional seasons. Installation is simplified by the included kit, and the unit’s feature set focuses on manual and onboard programmability.
Midea 12,000 BTU Smart Inverter Air Conditioner Window Unit With Heat
The Midea 12,000 BTU unit combines variable-speed inverter technology and a heat pump function to provide both cooling and heating for rooms up to 550 sq. ft. It’s Energy Star rated and engineered to reduce energy consumption compared to traditional fixed-speed units.
Controls include an LED display, five modes (Heat, Auto, Cool, Dry, Fan), three fan speeds, and a 24-hour timer. Smart features allow remote control via app and integration with Alexa and Google Assistant. Note: the heat pump function is limited when outside temperature drops below about 41°F, per manufacturer guidance.
Use cases: Suited for users prioritizing energy efficiency and remote/smart control, and for spaces where heat pump supplemental heating is appropriate during cool weather above the unit’s effective outdoor temperature threshold.
Midea 8,000 BTU Smart Inverter Air Conditioner Window Unit With Heat
This Midea 8,000 BTU model is designed for smaller rooms up to 350 sq. ft. It uses inverter technology and a heat pump to offer year-round comfort with reduced energy usage. The unit features Wi‑Fi connectivity and voice control, plus an accessible washable filter.
Operational modes mirror the larger Midea unit — Heat, Auto, Cool, Dry, Fan — and the unit includes eco mode and timer capabilities. As with other heat pump window units, heating performance is temperature-dependent and may be limited below roughly 41°F.
Use cases: Appropriate for medium bedrooms, small living spaces, or apartments where a compact unit with smart control and efficient inverter operation is desired.
GE AWGP08WWA 8,000 BTU Smart Heat/Cool Electronic Window Air Conditioner
The GE AWGP08WWA uses heat pump technology to deliver both cooling and heating for rooms up to 350 sq. ft. The manufacturer highlights improved heating efficiency relative to resistance-based electric heaters, noting faster and more energy-efficient warm-up via the heat pump.
Smart functionality includes Wi‑Fi-enabled control through the SmartHQ app, allowing remote monitoring and scheduling. The unit lists an 8,000 BTU rating for both heating and cooling, making it a compact option for medium rooms that need year-round climate control.
Use cases: Useful where app-based control and a compact footprint are priorities, and where a heat pump can provide adequate supplemental heating for milder cold conditions.
Heat Storm HS-1500-PHX-WIFI Infrared Heater, Wi‑Fi Wall Mounted
The Heat Storm HS-1500 is a wall-mounted infrared electric heater with Wi‑Fi control. Its design emphasizes space-saving installation and targeted radiant heating, making it suitable for bedrooms, kitchens, or offices where spot warming and wall installation are preferred.
Features include Wi‑Fi control via phone, a touchscreen digital thermostat, remote control, and tip-over safety shutoff. As an infrared heater, it warms objects and people directly rather than primarily heating air, which can feel efficient for localized comfort.
Use cases: Best where a dedicated wall-mounted electric heater is desired instead of a window AC. It’s appropriate for homeowners seeking zoned heat with smart control and minimal visual impact on windows.
Buying Guide: How To Choose A Window-Mounted Heater
Selecting the right window-mounted heater or window AC with heat involves several technical and practical considerations. The sections below outline the key factors to compare.
Type And Intended Use
- Window AC With Supplemental Heat (Heat Pump Or Electric): Combines cooling and heating; heat pumps are more energy-efficient but limited at low outdoor temperatures. Supplemental electric heat provides additional warmth but is typically not meant as sole heating in very cold climates.
- Wall-Mounted Electric Infrared Or Convection Heaters: Provide targeted heating and free up the window; infrared units heat objects and people, while convective units warm air.
Coverage And BTU Rating
Match the unit’s BTU rating to room size. Higher BTUs are needed for larger rooms. Example ranges from the selected products: 8,000 BTU for ~350 sq. ft., 12,000 BTU for up to ~550 sq. ft., and 14,000 BTU for up to ~700 sq. ft. Use manufacturer guidance for coverage and account for ceiling height, insulation quality, and sun exposure.
Heating Technology And Outdoor Conditions
- Heat Pump Units: Efficient for mild to moderate cold but may lose effectiveness below ~41°F. Ideal for transitional seasons and moderate climates.
- Electric Resistance Or Infrared Heaters: Provide consistent heat regardless of outside temperature, but typically consume more electricity for sustained whole-home heating.
Energy Efficiency And Ratings
Look for Energy Star certifications and inverter technology for lower operating costs. Efficiency metrics like CEER for cooling or COP for heat pumps can indicate long-term operating expense differences.
Controls And Smart Features
- Local Controls: On-unit electronic panels, timers, and programmable modes are standard.
- Remote And Wi‑Fi Control: Allows scheduling, remote start/stop, and integration with voice assistants. Useful for preheating or remote management.
Installation And Electrical Requirements
Verify whether the unit requires standard 115V power or higher-voltage connections (e.g., 230V or dedicated 20-amp circuits). Window AC units typically include a mounting kit; wall-mounted units will require secure wall attachment and possibly professional installation for wiring.
Noise And Comfort Modes
Noise levels vary by model. Look for listed decibel ratings if bedroom quietness is important. Comfort modes like eco, sleep, and dehumidify add utility and can affect perceived comfort and energy use.
Maintenance And Filter Access
Choose units with easy-to-remove washable filters and straightforward access panels for routine cleaning. Regular filter maintenance helps preserve efficiency and indoor air quality.
Safety Features
For electric heaters, check for tip-over protection, overheat cut-off, and certified safety listings. For window AC with heating, ensure proper sealing and secure mounting to reduce drafts and prevent water ingress.
Comparison Perspectives
- Cost vs. Efficiency: Heat pumps typically reduce running costs compared to resistance heating but may cost more upfront.
- Year-Round Use: Window AC units with heat provide both summer cooling and fall/spring heating, offering value for seasonal climates.
- Space And Aesthetics: Wall-mounted electric heaters free window space and preserve views; window units occupy the opening but integrate cooling and heating.
- Climate Suitability: In colder regions where temperatures frequently fall below a heat pump’s effective range, consider supplemental resistance heating or a dedicated primary heating system.
