The air conditioner is cooling but not too cold. When I call for repairs, they say it is normal. What is going on?

Today, Zhao Yu will tell you about this fault. This kind of fault is more common in

, inverter air conditioners, , and environmentally friendly refrigerants.

What exactly is going on? Some inverter air conditioners and environmentally friendly refrigerant air conditioners have to be relocated several times. Install. That's all.

is not that cool anymore. This is because environmentally friendly refrigerant has relatively high vacuum requirements. If there is air in the system, the thermal efficiency of the air conditioner will decrease, which leads to the air conditioner not being cool. After

has been moved several times, it may be that the installation personnel did not operate properly, or did not vacuum or , or the vacuuming time was too short, resulting in too much air in the system and it was not cool. Some installers do not bring vacuum pump at all and do not vacuum, that's why. If it is caused by multiple moves of the machine, it is not cool. We only need to use a vacuum pump to remove all the refrigerant and add new refrigerant to solve the problem. At the same time, use the vacuum pump to pump for a while to ensure that the vacuum is high enough and for a longer time.

This phenomenon may also be due to the following reasons: 1. The evaporator of the internal unit is too dirty, including the filter, which reduces the heat exchange efficiency. 2. The condenser of the outdoor unit is too dirty and the heat exchange efficiency decreases. Both of these require thorough cleaning of the internal and external units of the air conditioner. 3. The compressor is boring and the exhaust is insufficient. 4. The four-way valve has a bit of blowby. 5. The outdoor unit does not dissipate heat well and should be placed in a poorly ventilated place. 6. Add too much fluoride. In this case, the pressure may rise slightly, so be sure to check carefully.

When your air conditioner is working normally, you will gradually get used to the temperature of the air coming out of the vents. So it's easy to identify when your system isn't performing well. This usually starts when you notice that your home isn't as cold as usual, or your air conditioner seems to be going through longer cooling cycles. When you put your hand over the vent, you'll notice that the air outside is unusually warm. Today, we’re going to discuss why the air from your air conditioner might not be as cold as usual and what you can do to prevent this problem from happening!

The cooling coil is dirty. Your air conditioner has two sets of coils : an evaporator coil located inside the home and a condenser coil located outside the home. The evaporator coil is responsible for absorbing heat from the air in your home, and the condenser coil is responsible for releasing the heat into the outside air. If dirt accumulates on any set of coils, a layer will form, making the heat transfer process more difficult. As a result, there will be less heat in your home, and the supply air to your home will be warmer than usual.

evaporator coil frozen. A common problem with air conditioners is that the evaporator coil can freeze. When this happens, it can cause the same type of problems as when the coils become dirty, as ice forms a layer on the coils, preventing heat transfer. How does

prevent my air conditioner from causing this failure?

1, find a professional master to install and repair air conditioners. Technical experience is very important.

2, clean the internal and external units of the air conditioner regularly and ensure that the air filter is replaced once a month.

This not only protects your cooling coils from dirt buildup, it also prevents them from freezing.
