LG 18,000 BTU Window Air Conditioner With Heat

Check Price on Amazon

This 18,000 BTU window AC provides robust cooling and a supplemental heat mode designed for larger rooms—manufacturer guidance lists coverage up to 1,000 sq. ft. It requires a 230/208V LCDI plug (NEMA 6-20), so electrical compatibility is an important pre-purchase check.

Features include digital controls, a remote, 24-hour timer, removable washable filter, and 4-way air deflection. The unit offers multiple fan and heat/cool speeds to adjust comfort and airflow distribution.

Notes: The supplemental heat is intended as a backup or seasonal boost rather than primary home heating in very cold climates. Verify window and circuit compatibility before installation for safe operation.

GE AWGP08WWA 8,000 BTU Smart Heat/Cool Window Air Conditioner

Check Price on Amazon

GE’s 8,000 BTU window AC combines cooling and heat pump heating for rooms up to 350 sq. ft. The unit emphasizes advanced heat pump tech delivering up to 2x more effective heating compared to traditional electric resistance heating.

Smart integration via the manufacturer’s Wi‑Fi app allows remote monitoring and control. The product includes a remote control and an installation kit to simplify setup. The washable filter and user-friendly interface add to everyday convenience.

Notes: Heat pump efficiency depends on outdoor temperature ranges; these systems are most effective as supplemental heat or in milder winter conditions.

ROVSUN 8000 BTU Window Air Conditioner With Heat

Check Price on Amazon

The ROVSUN unit is marketed as an all-season solution, offering 8,000 BTU cooling and 4,000 BTU heating, plus dehumidification and fan-only modes. Coverage is listed at up to 350 sq. ft.

Controls include LED display, five operating modes, three fan speeds, a 24-hour timer and Eco setting. The unit supports Wi‑Fi/app and voice control with Alexa and Google Assistant for remote scheduling and routines.

Notes: The listed heating capacity is lower than the cooling capacity—this signals the heating mode is supplemental. The product emphasizes easy filter access and multiple control options for flexible operation.

Keystone 23,200 BTU Window-Wall Air Conditioner With 16,000 BTU Heat

Check Price on Amazon

This high-capacity 23,200 BTU cooling unit includes 16,000 BTU supplemental heating and is sized for spaces up to 1,500 sq. ft. It’s designed for window-wall installation where larger cooling and heating loads are required.

Capabilities include cooling, supplemental heating, dehumidification and fan circulation. The remote control reads room temperature and updates the unit periodically for tighter temperature control. The manufacturer stresses the supplemental heating mode is not intended as a primary home heating source in extremely cold conditions.

Notes: Due to its size and power, confirm electrical and structural compatibility before purchase and installation, including 230V circuit needs if applicable.

Buying Guide: How To Choose The Right Window Air Conditioner With Heater

Selecting the proper window air conditioner with heat requires balancing room size, heating method, energy efficiency, and installation/electrical requirements. Use the guide below to compare models and make an informed choice.

1. Match Capacity To Room Size

Cooling capacity (BTU) should be chosen based on room square footage. As a general reference:

• Up to 350 sq. ft. — ~8,000–10,000 BTU units (typical bedroom/apartment)
• Up to 1,000 sq. ft. — ~18,000 BTU (larger living areas)
• Up to 1,500 sq. ft. — 20,000+ BTU or through-the-wall units

Oversizing can cause short cycling and humidity issues; undersizing will struggle to maintain comfort.

2. Understand Heating Type And Limits

Two common heating approaches are heat pump and electric resistance/supplemental heat:

• Heat Pump: Reverses refrigeration cycle to provide heat. Efficient in mild-to-moderate cold but less effective below certain outdoor temperatures (often ~40°F).
• Supplemental Electric Heat: Provides direct resistance heat and works in colder conditions but generally consumes more energy.

Check manufacturer notes about operating temperature ranges and whether the unit is designed as a primary heat source.

3. Energy Efficiency And Certifications

Look for Energy Star certification and inverter technology for reduced energy use. Variable-speed compressors (inverter) adjust output to meet demand and save power compared to single-speed compressors.

Also check estimated energy savings claims and seasonal energy efficiency ratings where available.

4. Electrical And Installation Considerations

Confirm voltage and plug requirements. Higher-capacity units often require 230/208V circuits or specific LCDI/NEMA plugs. Verify window size and mounting kit compatibility. For bulky units, consider window-wall preparations and professional installation.

5. Noise, Design, And Placement

Sound levels vary widely. U-shaped or inverter designs tend to reduce vibration and external noise. Consider placement to minimize noise impact in bedrooms or living areas.

6. Controls, Smart Features, And Convenience

Smart connectivity (Wi‑Fi, app control, voice assistant) provides remote scheduling and monitoring. Basic remote control and programmable timers are helpful for daily convenience. Washable filters and accessible panels simplify maintenance.

7. Climate And Usage Patterns

In milder climates, a heat pump-equipped window AC can handle both cooling and heating efficiently. In colder climates or where temperatures regularly drop well below freezing, supplemental electric heat or a dedicated heating system may be required.

8. Maintenance And Longevity

Regular filter cleaning, seasonal checks, and proper off-season storage (if removed) extend unit life. Check warranty terms and availability of service parts.

9. Comparison Perspectives

Performance vs. Cost: Higher upfront cost models with inverter or heat pump tech often yield lower operating costs. Heating Capacity vs. Climate: Models with higher heating BTUs or dedicated electric heat are preferable in colder regions. Smart Features vs. Simplicity: Wi‑Fi and voice control add convenience but may require software updates and account setup.

10. Safety And Compliance

Ensure any required safety certifications are present and that installation meets local electrical codes. Use proper window supports or braces for heavier units, and ensure LCDI protection where required.

Use the table and product summaries above to shortlist units that match your room size, electrical setup, and desired features. Prioritize verified cooling/heating capacity, energy efficiency, and installation feasibility when making the final selection.
