Complete Comparison & Main Differences
When it comes to reliable portable air conditioners, Whynter is one of the most trusted brands on the market. Two of its most popular models — the Whynter ARC-14S and the Whynter ARC-14SH — have earned impressive reputations for efficiency, cooling power, and user-friendly design. However, consumers often wonder what sets these two models apart. Are the differences worth the extra cost? Which one should you buy for your home, office, or RV?
In this detailed comparison, we’ll explore every aspect of both models — from design, cooling capacity, and dehumidifying performance to energy efficiency and noise levels. By the end, you’ll know exactly which portable AC suits your needs best. Let’s dive into the Whynter ARC-14S vs 14SH portable air conditioners showdown.
Main Difference Between Whynter ARC-14S and 14SH
Core Functionality
The main difference between the Whynter ARC-14S and Whynter ARC-14SH is that the ARC-14SH includes a built-in heater function, making it a 4-in-1 unit (air conditioner, heater, dehumidifier, and fan). The ARC-14S, in contrast, is a 3-in-1 model that functions as an air conditioner, dehumidifier, and fan but lacks heating capability.
This means the ARC-14S is ideal for those needing cooling and humidity control during hot months, while the ARC-14SH is perfect for users seeking a year-round comfort solution that can handle both cooling and heating.

Performance Comparison
Cooling Power and Coverage
Both models deliver an impressive 14,000 BTU cooling capacity, designed to effectively cool rooms up to 500 square feet. Their dual-hose design enhances cooling efficiency by using one hose to draw in outdoor air and another to expel hot air, preventing negative pressure and ensuring faster temperature control. This makes them ideal for medium to large rooms, offices, and apartments.
Heating Function (14SH Only)
The standout advantage of the ARC-14SH is its heating capability. With a 13,000 BTU heating output, it works efficiently during colder seasons, transforming your portable AC into a full-fledged year-round comfort system. The electric resistance heater evenly distributes warm air, making it ideal for homes without central heating or for supplemental warmth in specific rooms.
Energy Efficiency
Both models are Energy Star rated, offering reliable performance without excessive electricity consumption. The ARC-14SH may use slightly more power when heating, but overall, both units remain efficient for their class thanks to advanced compressor technology and the eco-friendly R-32 refrigerant, which has lower environmental impact compared to older R-410A gases.
Design and Build Quality
Durability and Aesthetic Appeal
Both air conditioners feature a sleek platinum-and-black body that blends well with modern interiors. Built with durable ABS materials, they are designed for longevity and frequent use. The casters allow for easy mobility, letting you roll the unit between rooms effortlessly.
Control Panel and Remote Operation
Both the ARC-14S and 14SH include an intuitive digital control panel and a full-function remote. You can easily adjust temperature, mode, fan speed, and timer settings without leaving your seat. The LED display offers real-time status updates, and the units can be programmed for 24-hour operation cycles.
Dehumidifier Performance
Moisture Removal Capacity
One of the strengths of both models is their high dehumidifying power. They can remove up to 101 pints of moisture per day, making them suitable for humid regions. This function operates independently, so you can use it even when cooling or heating is off — helping maintain comfortable humidity levels year-round.
Noise Levels
Quiet Operation
At around 56 decibels, both models are relatively quiet compared to most portable air conditioners. The dual-hose system not only improves cooling efficiency but also reduces noise caused by internal pressure differences. This makes them suitable for bedrooms and offices where noise reduction is essential.
Maintenance and Filter System
Filter Quality
Both units use a combination of washable pre-filters and activated carbon filters, which trap dust, pet hair, and odors. Regular cleaning ensures optimal performance and prolongs the life of the machine. The carbon filter can be replaced periodically to maintain clean air circulation.
Drainage and Cleaning
Maintenance is straightforward thanks to Whynter’s auto-drain technology. This system recycles moisture collected during dehumidifying to cool the condenser coils, reducing manual draining frequency. However, in extremely humid conditions, you might need to occasionally empty the water pan manually.
Portability and Installation
Easy Setup
Whynter includes a complete installation kit with both models, featuring dual exhaust hoses, a window kit, and adapters. Setup typically takes less than 15 minutes. The window kit fits most vertical or horizontal windows (up to 46 inches wide), making it ideal for renters or users who don’t want permanent installation.
Mobility
At about 80 pounds, both units are on the heavier side, but the durable caster wheels and side handles make movement manageable. The ARC-14SH may feel slightly heavier when heating components are active, but the difference is negligible in daily use.
Environmental Impact
Eco-Friendly Refrigerant
Both air conditioners use R-32 refrigerant, which has a lower Global Warming Potential (GWP) than older refrigerants. This makes them an environmentally responsible choice for eco-conscious users. Additionally, the efficient dual-hose design reduces operational time, further minimizing carbon footprint.
Price and Value
Cost Considerations
The Whynter ARC-14S is generally priced slightly lower than the 14SH, making it an excellent option for those who only need cooling and dehumidifying. The ARC-14SH, however, offers better overall value for year-round use since it combines both heating and cooling in one device — eliminating the need for separate appliances.
Final Verdict: Which One Should You Choose?
Choosing Based on Your Needs
If you live in a region with hot summers but mild winters, the Whynter ARC-14S offers exceptional performance, efficient cooling, and strong dehumidification without the added cost of heating features. It’s ideal for bedrooms, offices, and living areas where cooling is the top priority.
However, if you experience both warm and cold seasons and want a portable, all-in-one solution, the Whynter ARC-14SH is the better investment. Its built-in heating function provides year-round climate control while maintaining the same cooling efficiency as the ARC-14S.
Conclusion
In summary, both the Whynter ARC-14S and Whynter ARC-14SH stand out for their dual-hose efficiency, powerful performance, and eco-friendly operation. The key difference lies in the heating capability — the ARC-14SH includes it, the ARC-14S does not. For users wanting flexibility and full-season comfort, the ARC-14SH is the superior choice, while the ARC-14S remains a top performer for cooling-only needs.
Regardless of which model you choose, Whynter’s reputation for quality engineering ensures you’re investing in a durable, efficient, and user-friendly portable air conditioner that will serve you well for years to come.
