Portable Air Conditioners

Frequently Asked Questions

How do I choose the right size air conditioner portable for my room?

To select the right portable air conditioner for your room, first calculate the room's area in square meters (length × width). Our website indicates the recommended room size for each portable air conditioner, so you can choose as needed. However, please note the calculation should be adjusted for specific conditions - rooms with large windows or direct sunlight exposure may need 10-20% additional capacity, while spaces with ceilings higher than the standard 2.7 meters benefit from another 10-15% boost.
Kitchens or frequently occupied rooms also need more capacity to account for additional heat sources. A portable AC with a higher energy rating can ensure better performance. Avoid oversizing to maintain proper dehumidification and efficiency.

What is the typical warranty period for a portable AC unit?

Costway portable air conditioning units are classified as home appliances and come with a one-year limited warranty. This warranty covers defects in materials or workmanship under normal residential use. It does not include damage caused by misuse, abuse, accidents, or any unauthorized attempts to repair the unit.
If you need to return a product due to a quality-related issue within the warranty period, Costway will cover the return shipping costs. However, if the return is not related to product quality, such as if you changed your mind, the return shipping fee will be deducted from your total refund.

How do I clean and maintain a portable air conditioner unit for optimal performance?

1. Regular Cleaning (Monthly During Use)
Air Filter: Remove and vacuum or wash the filter (check the manual in the package). Let it dry completely before reinstalling. Clogged filters reduce airflow and efficiency.
Exterior & Vents: Wipe down the unit’s exterior and vents with a damp cloth to remove dust and grime.
Condenser Coils: Use a soft brush or vacuum to clear dust from the rear coils (improves cooling efficiency).
2.Deep Cleaning (Every 3-6 Months)
Drain the Condensate Tank: Empty the built-in water reservoir (if applicable) to prevent mold and leaks. Some units auto-evaporate moisture—check your model.
Clean the Evaporator Coils: Use a coil cleaner spray (available at hardware stores) to remove built-up dirt. Check the Exhaust Hose: Detach and inspect for blockages or kinks—clean with a pipe brush if needed.
3.End-of-Season Maintenance (Before Storage)
Fully Drain & Dry: Remove all water to prevent mold growth.
Clean the Entire Unit: Wipe interior surfaces with a mild detergent solution.
Store Properly: Keep in a dry, covered place (preferably in its original box) to protect from dust.
Pro Tip: Always unplug the unit before cleaning and refer to our manual for model-specific care. Proper maintenance extends lifespan and keeps energy bills low!

Are portable air conditioners energy efficient?

Portable air conditioners are generally less energy-efficient than split systems, often consuming 20–40% more energy to achieve similar cooling performance. This is primarily due to their single-hose design and the need to work harder to cool a space.
However, when used thoughtfully, portable AC units can still be effective and cost-efficient, especially in rentals or small spaces where permanent installations aren't feasible. To enhance their efficiency:
Use ceiling fans: Pairing your portable AC with ceiling fans can help distribute cool air more evenly, reducing the workload on the AC unit.
Regular maintenance: Clean or replace filters monthly to maintain optimal airflow and cooling efficiency.
Optimal placement: Position the unit near a window for venting and away from heat-generating appliances.
By following these practices, you can maximize the performance of your portable air conditioner and achieve more efficient cooling.

Do portable air conditioners need to be installed?

Costway portable air conditioners require minimal installation and are designed for a user-friendly setup. Each unit comes with all necessary accessories, including an exhaust hose, window kit, and detailed instructions. Installation typically involves connecting the exhaust hose to the unit and fitting the window kit to a nearby window for proper ventilation.
No permanent modifications or professional assistance are needed, making them ideal for renters or temporary spaces. With clear guidance provided in the user manual, most customers can complete the setup in under 30 minutes. For further assistance, our customer support team is always ready to help.

Are portable air conditioners noisy?

Noise levels vary by model and setting of portable AC.
1. Typical Noise Levels
- Decibel Range: Most portable ACs operate at 50–60 dB (similar to a loud conversation or dishwasher).
- Low fan mode: ~50 dB
- High cooling mode: Up to 60+ dB
2. What Causes Noise?
- Compressor: The loudest component (especially during startup).
- Fan motor: Noise increases on high-speed settings.
- Vibration: Poor placement (e.g., uneven floors) can amplify sounds.
3. Quieter Options
- Dual-hose designs: Reduce strain on the compressor (less noise).
- Look for "sleep mode" (dims display and lowers fan speed at night).
4. How to Reduce Noise
- Place on a Soft Surface: Use a rubber mat to absorb vibrations.
- Keep Away from Bed: Position the unit at least 2 meters from sleeping areas.
- Seal Window Gaps: Prevents rattling from exhaust hose movement.
- Clean Filters Monthly: Clogged filters force the fan to work harder (louder).
