Installing an air conditioner may seem simple, but the correct placement of the indoor and outdoor units is crucial for comfort and efficiency. Poorly chosen locations can lead to drafts, noise, or uneven cooling. In this blog, we explain what to consider to ensure your air conditioner performs optimally and provides comfort throughout your home.
Best location for the indoor unit
Consider carefully where the air conditioner is needed most. In the living room, it provides cooling during the day, while in the bedroom it ensures comfort at night. The location largely determines the system’s efficiency and usability. Keep the following points in mind when installing your indoor unit:
- Avoid heat sources: Place the unit where the temperature sensor is not affected by heat from ovens, radiators, or other appliances, so it can work accurately without unnecessary cooling or heating.
- Mount the unit high on the wall: Cold air naturally sinks, so placing the unit higher helps distribute air evenly throughout the room, creating a comfortable climate without drafts or cold spots.
- Allow sufficient clearance around the unit: Leave at least 10 cm of free space around the unit to ensure proper airflow for efficient operation.
- Attach the unit to a sturdy wall: The indoor unit must be securely mounted on a stable wall that can support its weight.
- Provide a condensate drainage solution: Cooling produces condensate that must be drained via a hose. Ensure a nearby outlet or external drainage option is available.
- Ensure unobstructed airflow: Avoid corners or placing the unit behind furniture or curtains. Air must circulate freely to maintain a stable, comfortable temperature throughout the room.
Where to place an air conditioner in your home
Air conditioner in the bedroom
A properly placed bedroom air conditioner ensures a comfortable night’s sleep during warm nights. Keep the airflow indirect and even, avoiding direct contact with the bed to prevent discomfort or potential health issues.
Air conditioner in the living room
Choose a wall with sufficient surrounding space for proper air circulation. A central location is usually most effective. Consider aesthetics as well, selecting a model that blends with your interior design.
Air conditioner in the attic
An attic unit is only effective if the space is well-insulated; otherwise, cool air is quickly lost, and the unit overworks. If the attic is insulated and used as a bedroom, office, or hobby room, an air conditioner adds significant comfort and productivity during hot summer days.
Air conditioner in the kitchen
Kitchen installation requires extra attention due to heat sources like stoves and ovens. Ensure warm and cool air do not mix directly to prevent inefficiency. Choose a strategic location, such as a corner where air can circulate freely.
Air conditioner in your office
A comfortable workspace improves well-being and productivity. An air conditioner keeps the indoor climate pleasant, especially during hot days. Combine it with adequate daylight, ergonomic furniture, and noise reduction for an efficient and comfortable home office or workplace. Ideally, install the unit centrally, just below the ceiling and preferably above a window.
Key considerations
There are several points that are important not to forget when having air conditioning installed.
Minimize the distance between indoor and outdoor units
Shorter distances improve energy efficiency. The shorter the distance, the less energy is lost transporting the refrigerant. Standard installations usually keep a maximum of 20 meters to optimize performance.
Minimize the height difference between units
A large height difference between indoor and outdoor units can negatively affect system performance. If the outdoor unit is much higher than the indoor unit, the system works harder to move refrigerant, increasing costs. Consider this when positioning the units.
Common installation mistakes
Avoid these pitfalls to ensure optimal operation:
- Indoor unit mounted too low: Causes poor air distribution and uneven cooling.
- Direct airflow on bed or desk: Can lead to discomfort, colds, or muscle pain.
- Outdoor unit too close to walls or shrubs: Blocks ventilation, causing overheating and lower efficiency.
- Poor maintenance access: Makes cleaning or repairs difficult, shortening system lifespan.
- Uninsulated attic: Forces the unit to work harder, increasing energy use.
Always consult a professional installer to avoid these issues and ensure efficient, long-lasting operation.
The importance of professional installation
Professional installation is recommended for several reasons, especially for split air conditioners, where certified installation is legally advised:
- On-site assessment: Ensures a thorough evaluation of the room and installation requirements.
- Technical accuracy and comfort: Guarantees proper installation that is both efficient and comfortable for users.
- Prevents errors that shorten lifespan or increase energy consumption: Avoids mistakes that could damage the system or raise operating costs.
- Warranty and post-installation service: Professional installation often comes with warranties and aftercare for long-term reliable performance.
