When choosing air conditioners, most people are concerned about the brand, efficiency, and horsepower. They often miss a key factor, which is the installation position. In fact, even if you purchased a high-efficiency air conditioner, if the installation position is unconventional, then the cooling performance will be decreased and energy consumption will be high, or the life span will be shortened, etc. So how important is the installation position? How to choose a perfect position for installation? Here we will explain and help you pick out the best position to install your air conditioner.

 

I. The impact of improper indoor unit location

 

1. Uneven cooling, bad comfort feeling

If the air conditioner is installed on one side or locked by the furniture in the room, the cold air can not be spread evenly. This will easily lead to "one side cold, other side warm" and greatly discount the feeling of comfort.

 

2. Lower cooling efficiency, more energy consumption

The air conditioner starts frequently to adjust the temperature, consuming more electricity and damaging the air compressor easily. It's not cost-effective in the long run.

 

3. Blow directly toward human body; it triggers "air conditioner illness"

Installation at a lower position or facing the bed will make the cold air blow directly on the head or body, easily lead to "air conditioner illnesses" such as cold, headaches, muscle stiffness, etc.

 

The indoor unit shall be installed in the middle-upper part of the room, avoiding the positions that could blow directly on the human. The air vent is toward the open zone of the space, which is better for cold air to spread.

 

 

II. The impact of improper outdoor unit location

 

1. Bad radiation, lower cooling ability

If the outdoor unit is placed under direct sunlight or bad ventilation and the heat can not be radiated effectively, then the cooling efficiency will be greatly decreased.

 

2. More noise and vibration

Installing on window sills, corners, or weak structural areas can cause noise and vibration problems due to resonance or unstable support.

If the air conditioner is installed on window sills, corners, or weak structural areas, because of the resonance or unstable support, it will make noise and vibration problems.

 

3. Lifespan problem

Being long-term exposed to sunlight or heavy dust accumulation will accelerate the aging of the outdoor unit, influencing the lifespan of the whole unit.

 

The outdoor unit should be placed in a cool and ventilated location, such as a balcony, and keep a heat radiation area of at least 30 cm around it.

 

 

III. Common misconceptions inventory

Misconceptions	Description
Concern on beauty rather than the air flow.	If the air conditioner is installed too high or blocked by the ceiling, cold air circulation is hard to achieve.
The outdoor unit is too close to the wall.	The space for heat dissipation is not enough, affecting the operation efficiency of the compressor.
The indoor unit faces the bed.	The cold air blows directly to the human body, influencing our health.
The distance between indoor and outdoor units is too long.	This will lead to too long a connecting pipe, increasing the energy consumption and installation cost.

 

IV. Advice for the best installation position.

 

• Bedroom: It should be installed in the upper position of the side wall, avoiding facing the bed.
• Living room: It's better to choose the position near the center of the ceiling or the unblocked wall.
• Office: Keep it away from the workplace, ensuring the cold air is dispersed in the activity area.
• Child's room: Avoid direct blowing and concern yourself with the adjustable wind direction.

 

 

V. Reasonable installation consumes half the efforts

 

Whether your home air conditioner works well or not, the installation position determines. Proper installation can not only improve cooling efficiency and energy-saving effects but also extend the lifespan and secure family health. As for an air conditioner, 30% is based on the quality and 70% is on the installation. Please refer to the professional guidance before installation, or give this job to the servicemen.

 

Standing air conditioner inverter is normally more expensive than non-inverter ones; whether it is worth purchasing depends on your demands and places. Let's analyze it from several aspects and see if this investment is worth doing.

 

1. Why is inverter floor standing air conditioner more expensive than normal ones？

Well, the key difference between inverter and non-inverter air conditioners is the working method of the compressor.

• Inverter AC: By adjusting the rotating speed of the compressor, it could control temperature precisely, reducing energy consumption.
• Non-inverter AC: The compressor has only two modes, on and off, which leads to high starting power, large temperature fluctuation, and high energy consumption.

Floor standing air conditioners have high power consumption themselves. With inverter technology, the price will be absolutely higher, but the advantages it brings are obvious.

 

2. Whether it is worth buying an inverter floor standing air conditioner, we can check from the following points.

Suggested crowd and scenario

• Large spaces: Living rooms, conference offices, and stores. Floor standing air conditioners are suitable for large areas, and with inverter technology, it could improve the comfort and the energy-saving effect.
• Long-time usage: Homes and offices that use air conditioners all day long. Inverter air conditioners could save more energy when operating for a long time.
• People who pursue comfort: They request air conditioners with stable temperature and low noise, avoiding sudden cold and heat.

 

Unsuitable crowd and scenario

• Small space: Rooms within 10 ㎡. Floor standing air conditioner is to big to place in such a small area, which may lead to a waste of resources.
• Short-time usage: Use it for 1-2 hours per day only. Under such condition, the advantage of inverter energy saving is not obvious, and the payback is slow.
• Tighten budget: If we have a limited budget, then a non-inverter AC with smart socket would also save some energy.

 

 

3. Key comparisons between inverter and non-inverter floor standing air conditioners.

Items	Inverter standing air conditioner	Non-inverter standing air conditioner
Price	Expensive.	Cheap.
Energy consumption	Saving electricity, long-term usage will be cost-effective.	Consuming more power, making it suitable for short-term usage.
Comfort	Constant temperature, low noise.	Large temperature fluctuation, loud noise.
Lifespan	Longer lifespan compressor.	Frequent start-up affects the compressor lifespan.
Maintenance	More complex technology, higher maintenance costs.	Easy maintenance, low cost.

 

If we use the air conditioner frequently and with a large room, then we choose inverter type. If we need it cheaper and use it seldom, then we'd better choose the non-inverter type.

 

4. Floor standing air conditioner with inverter can save energy; will it truly bring payback to us?

Let's take 3 horse power inverter and non-inverter floor standing air conditioners as an example:

• Power consumption (8 h/day): inverter ac 1.8 kW on average.
• Power consumption (8 h/day): non-inverter ac 2.5 kW on average.

During a summer (90 days on average), it saves 63 kW (2.5*90-1.8*90) of electricity. Then we can calculate how much the money it saves in a summer. After several years, the saved costs could cover the additional money that we had paid on the inverter air conditioner.

If we truly use the air conditioner often, then the inverter type can definitely pay back and save more money.

 

 

5. Purchasing tips on inverter floor standing air conditioners.

• Focus on "Full DC Inverter". Compressor, fan, and motors—all parts are inverter, and the energy saving effect will be much better.
• Focus on "Energy Efficiency Label". Class I is the most effective.
• Focus on "Brand and After-sales". Famous brands from the USA, Japan, Korea, China, etc.
• Focus on “Additional Features".  Dehumidification, air purification, smart WIFI control, etc.

 

6. Should we buy it?

So, if we use air conditioners very often (longer time and larger space), an inverter floor mounted air conditioner is worth purchasing, which is energy-saving and comfortable.

But if we use it for a short time at home and our budget is limited, then a normal non-inverter air conditioner is also considerable. It costs less. However, in a long period, the electricity bill will be higher.
