Customer Reviews

Customer feedback for the Della Portable Air Conditioner reveals a generally positive reception with some notable considerations. With a 4.2 out of 5 star rating from 72 reviews, users particularly praise the unit’s quiet operation and ease of setup. One satisfied customer from California’s Central Valley noted, “Bought this for my son for a studio that has horrible insulation. The AC works amazing, we’re in the Central Valley, so this is much needed.”

Many customers appreciate the unit’s functionality, with several mentioning its effectiveness in spaces around 400 square feet. The quiet operation is consistently highlighted, with one reviewer stating they couldn’t hear it from across the room. The energy efficiency and portable design also receive positive mentions from multiple users.

However, cooling performance receives mixed reviews. While some customers report efficient cooling, others have experienced units that won’t cool at all. This inconsistency in cooling performance is the primary concern raised in negative reviews, suggesting potential quality control issues or suitability limitations for certain environments.

Key Features

Advanced Inverter Technology

The Della portable air conditioner utilizes DC inverter technology that sets it apart from traditional models. Unlike fixed-speed units that constantly turn on and off, the inverter compressor operates at variable speeds. It initially runs at high frequencies to rapidly cool your space, then maintains the set temperature with low-frequency operation. This results in significant energy savings and reduced noise levels.

Smart Home Connectivity

The WiFi-enabled smart features make this unit exceptionally convenient. Through the DELLA+ app, users can control all settings remotely, whether they’re at work or lounging on the couch. The integration with Alexa and Google Assistant adds voice control capabilities, allowing hands-free operation. The GEO Location feature can even adjust settings based on your location.

Comprehensive Climate Control

Beyond basic cooling, this unit offers multiple comfort features including sleep mode for nighttime operation, ECO mode for energy savings, and a 24-hour programmable timer. The three fan speeds with oscillation function ensure even air distribution throughout the room. The built-in dehumidifier with its impressive 70 pints/day capacity helps maintain comfortable humidity levels.

User-Friendly Design

The portable design with smooth-rolling casters makes it easy to move between rooms. The removable and washable double-layer filter protects against dust and pet dander, promoting healthier air quality. The full water level indicator and self-evaporation system minimize maintenance requirements.

Buying Guide for Della Portable Air Conditioners

Room Size and BTU Requirements

When selecting a Della portable air conditioner, accurately measuring your room size is crucial. The 14000 BTU model effectively cools spaces up to 450 square feet. For smaller rooms (150-250 sq ft), consider Della’s 8000 or 10000 BTU models. Remember that factors like ceiling height, sun exposure, and insulation quality affect cooling requirements. Rooms with poor insulation or excessive sunlight may need higher BTU ratings.

Energy Efficiency Considerations

The inverter technology in this Della model offers significant energy savings compared to traditional units. When comparing models, look for the SACC (Seasonally Adjusted Cooling Capacity) rating, which provides a more accurate representation of real-world performance. The 10,100 BTU SACC rating of this unit indicates efficient operation. Consider your local electricity rates and usage patterns to calculate potential savings over time.

Installation Requirements

Before purchasing, measure your window dimensions to ensure compatibility. The Della unit accommodates windows from 18.5 to 51 inches, covering most standard sizes. Check that you have a nearby electrical outlet, as the 6.6-foot cord may require an extension in some layouts. Plan for the exhaust hose placement, keeping in mind the 59-inch hose length provides good flexibility.

Smart Features and Connectivity

If you plan to use the WiFi features, verify that your home network operates on the 2.4 GHz frequency band. Many modern routers broadcast both 2.4 GHz and 5 GHz signals, but you’ll need to connect the unit to the 2.4 GHz network. Consider whether voice control through Alexa or Google Assistant aligns with your smart home setup. The app control feature is particularly valuable for pre-cooling rooms before arrival or adjusting settings without leaving bed.

Maintenance and Long-term Use

Factor in ongoing maintenance when choosing a portable air conditioner. The Della unit’s self-evaporation system and washable filters reduce maintenance needs. However, regular filter cleaning every 2-4 weeks ensures optimal performance. The 70-pint dehumidification capacity means less frequent water tank emptying in humid climates. Consider purchasing an extended warranty for peace of mind, especially given the mixed reviews on cooling performance. Always allow the unit to stand upright for 8 hours after delivery or moving to protect the compressor.

The Della 14000 BTU Ultra Quiet Inverter Portable Air Conditioner offers an impressive combination of smart features, energy efficiency, and quiet operation. While some users report cooling inconsistencies, the majority appreciate its functionality and convenience. For those seeking a modern, app-controlled cooling solution for spaces up to 450 square feet, this Della model presents a compelling option worth considering.
