LG 23,000 BTU Window AC With Heat

This LG window AC and heater combo is a high‑capacity option designed for large rooms up to about 1400 sq. ft. It provides both cooling and a supplemental heat mode for cooler days.
- Low Noise Performance: Operates down to about 50 dB on low mode for quieter operation during sleep or work.
- Heat Function: Supplemental heat option suitable for maintaining steady indoor temperatures.
- Fan Speeds: Two speeds for cooling, heating, and fan-only modes to customize airflow and comfort.
Considerations: This is a high BTU window unit that requires a compatible 230V window setup and sufficient space. It’s intended for permanent window mounting rather than portable use.
BLACK+DECKER Smart Portable AC With Heat

The BLACK+DECKER portable model is a four‑in‑one device with cooling, heating, dehumidifying, and fan modes. It targets rooms up to about 700 sq. ft. and adds smart controls via Wi‑Fi.

- Four-in-One Functionality: 14,000 BTU ASHRAE cooling (10,200 SACC) plus 10,000 BTU heat, dehumidifier and fan modes.
- Portability: Compact footprint and casters make it suitable for renters or multi‑room use.
- Smart Features: Mobile app control and voice compatibility with Alexa and Google Assistant for remote scheduling and monitoring.
Considerations: Portable units require a venting kit to exhaust hot air. Heating performance is best as supplemental heat in moderate cold conditions.
Whynter ARC-14SH Dual Hose Portable AC

The Whynter ARC-14SH is a dual‑hose portable unit with combined cooling and heating capability plus a built‑in dehumidifier. It emphasizes efficiency and quieter operation for rooms up to about 500 sq. ft.
- Dual Hose Design: Improves cooling efficiency and reduces intake of warm room air compared to single‑hose models.
- Quiet Operation: Operates around 51 dBA on low speed, suitable for bedrooms and living spaces.
- Dehumidification: Patented auto drain function with up to 71 pints/day dehumidifying capacity in ideal conditions.
Considerations: Dual‑hose systems need two openings or window kit adjustments. They tend to be more efficient for longer run times in larger areas.
Midea 12,000 BTU Smart Inverter Window AC

The Midea 12,000 BTU inverter window unit offers energy‑efficient cooling and a heat pump function for supplemental heat. It targets rooms up to about 550 sq. ft. and includes smart controls.

- Inverter Technology: Variable‑speed compressor for more efficient operation and up to 35% energy savings compared to baseline standards.
- Multi‑Mode Controls: Heat, Auto, Cool, Dry, Fan, plus 3 speeds, 24‑hour timer, ECO mode and washable filter.
- Smart Connectivity: App and voice control via Alexa/Google Assistant for remote operation and scheduling.
Considerations: Heat pump function may be limited when outdoor temperatures fall below certain thresholds (manufacturer notes ~41°F). Best suited for moderate climates or supplemental heating.
Wiytamo 14,000 BTU 4‑in‑1 Portable AC

The Wiytamo 14,000 BTU portable unit advertises both cooling and heating modes with auto swing airflow and multi‑mode operation. It aims to serve rooms up to about 700 sq. ft. depending on layout and insulation.
- Heating And Cooling Range: 14,000 BTU cooling (9,500 SACC) and 11,000 BTU heating capacity for year‑round comfort.
- Auto Swing Outlet: 80° swing distribution designed to spread conditioned air more evenly through a room.
- Remote & LED Display: Full function remote and front LED temperature display for convenient control.
Considerations: Portable performance varies with venting setup and room insulation. Check SACC (seasonal adjusted cooling capacity) values and expected coverage for realistic expectations.
Buying Guide: Choosing The Right Air Conditioner Plus Heater Combo
Selecting the right combo depends on room size, installation preferences, efficiency goals, noise tolerance, and whether you need portability. The following factors help compare units objectively.
1. Type: Window vs Portable vs Inverter Window
Window Units typically provide higher BTU per dollar and steady performance for fixed installations. They are often quieter than portable units and can offer efficient heat pump modes.
Portable Units offer mobility across rooms and simple setup with a vent kit. They generally trade off some efficiency and noise compared to window or split systems and require floor space.
Inverter Window Units use variable compressor speeds for improved efficiency, smoother temperature control, and potential energy savings over fixed‑speed models.
2. Heating Capability And Limits
Clarify whether the “heat” is a resistive supplemental heater or a heat pump. Heat pumps are more energy efficient but lose effectiveness in very cold climates. Many window/portable combos are intended for supplemental heating, not full replacement for a furnace.
3. BTU Ratings And Realistic Coverage
Look at both manufacturer BTU and SACC values where provided. SACC reflects real‑world cooling power. Match unit capacity to room size, insulation, ceiling height, and sun exposure for accurate performance expectations.
4. Efficiency And Energy Features
For long‑term savings, consider Energy Star certifications and inverter technology. Features like ECO modes and variable fan speeds can reduce runtime and energy use.
5. Noise Levels
Decibels matter for bedrooms and offices. Units listing operating noise (e.g., ~50–51 dB on low) are preferable for quiet environments. Portable models can be louder due to integrated compressor placement.
6. Venting, Installation, And Power Requirements
Window units require a secure window opening and may need higher voltage (e.g., 230V for larger units). Portable units require a window vent kit and space for exhaust hose routing. Confirm electrical circuit capacity and plug type before purchase.
7. Smart Controls, Timers, And Remote Operation
Wi‑Fi apps, voice control, and programmable timers add convenience and can improve energy management. Ensure app compatibility and consider whether remote control is included for daily convenience.
8. Dehumidification And Additional Modes
Units with built‑in dehumidifiers or dry modes can improve comfort in humid climates. Dual‑hose designs typically handle dehumidification and cooling more efficiently than single‑hose portable units.
9. Maintenance And Filter Access
Check for washable or easily replaceable filters and accessible panels for cleaning. Regular maintenance prolongs performance and maintains indoor air quality.
10. Portability And Space Considerations
Consider footprint, caster quality, and whether the unit will be moved frequently. Window units are fixed but free up floor space, while portable units require floor clearance and vent access.

Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
- Efficiency-Focused Buyers: Prioritize inverter window units or Energy Star rated models to reduce operating costs.
- Portability-Focused Buyers: Choose portable models with easy vent kits and casters for room‑to‑room flexibility.
- Noise-Sensitive Environments: Favor units specifying lower dB levels or those designed for quiet bedroom use.
- Large Space Coverage: Opt for higher BTU window units for open floor plans; dual‑hose portables can be effective in larger rooms when window mounting not feasible.
