Yes! Keeping your air conditioner clean ensures it runs efficiently and lasts longer. Here are a few simple maintenance tips:
Dust and dirt build-up can restrict airflow, so it’s best to clean or replace filters every few weeks during peak usage.
If you have a split system, make sure the external unit is free from leaves, dirt, or obstructions to maintain proper airflow.
To keep everything in top shape, it’s a good idea to have your air conditioner serviced professionally once a year.
Always check the manufacturer's guidelines for specific cleaning recommendations.
To install a portable air conditioner in a push-out window, you'll need a secure window sealing kit or create a custom seal with plexiglass or foam board. The goal is to cover the open space and provide a hole for the exhaust hose to vent hot air outside. It’s important to ensure a tight seal to prevent warm air from re-entering the room.
If you don’t have a traditional window, you can still vent a portable air conditioner through a sliding door, ceiling vent, or even a dryer vent. Some users create custom venting through a wall or use a drop ceiling panel. Proper ventilation is crucial for effective cooling and to avoid overheating the unit.
Portable air conditioners work by drawing in warm air, cooling it with a refrigerant system, and blowing the chilled air back into the room. The heat is expelled through an exhaust hose that typically vents out a window. They’re a convenient, plug-and-play option for cooling bedrooms, offices or rentals without the need for permanent installation.
Energy consumption depends on the type, size, and efficiency of the unit, as well as how often it’s used. Models with higher energy star ratings are designed to use less power while still keeping your space cool. To cut down on running costs, look for features like eco-mode, timers, and inverter technology, which helps regulate power use more efficiently.
The best portable air conditioner is one that suits your room size, insulation and layout. At Retravision, we stock leading brands like Dimplex and Omega Altise, offering models with features such as reverse cycle, built-in timers, and remote controls. Look for one with a high energy efficiency rating and the right BTU output for your space. You can explore our full range of portable air conditioners online.
Most air conditioners come with warranties ranging from 1 to 5 years, depending on the brand and model. Some manufacturers offer extended warranties on certain parts, such as compressors. It’s always a good idea to check the warranty details before purchasing to understand what’s covered.
Getting the right size air conditioner is crucial for both comfort and efficiency. Here’s a general guide based on room size:
Up to 20 m² – 2 to 2.5 kW
20–40 m² – 2.5 to 5 kW
40–60 m² – 4 to 6 kW
60–80 m² – 5 to 7 kW
80+ m² – 6 to 9 kW
However, other factors like ceiling height, insulation, and sunlight exposure can affect cooling needs. For a more precise recommendation, visit our Air Conditioner Buying Guide.
The best air conditioner for you depends on your needs and living situation:
Need to cool or heat a single room? A split system or window air conditioner is a great choice.
Living in a rental? A portable air conditioner is your best bet, as it doesn’t require installation.
Looking for an energy-efficient option? Evaporative coolers use less electricity and work well in dry climates.
Need whole-home cooling? A ducted system provides seamless temperature control across multiple rooms.
If you’re unsure, our Air Conditioner Buying Guide has all the details to help you decide.
