Why Is My Air Conditioner Not Cooling the House?

Office Chairs

The most common malfunction of climate systems is that the air conditioner does not cool the house well or blows air at room temperature. Such a failure in operating a split air conditioning system happens for various reasons. In the article, we will consider what to do if the air conditioner has worsened in cooling the air. A possible causes and recommendations on how to avoid this. Troubleshoot on your own or with the help of a specialist. Let’s talk about this in more detail.

Downed settings on the control panel

One of the main problems is the downed settings on the control panel. The air conditioner may not work in the cold because one information is displayed on the remote control and another in the system itself. First, you need to turn off the power to the air conditioner. You also need to remove the batteries from the remote control. After 5-10 minutes, try to turn on the system. On the remote control, you need to set the cooling mode with the “mode” button (on the screen, it is either a snowflake or cool) and the lowest temperature. Set the fan mode to maximum and wait 15 minutes. Most air conditioners do not immediately begin to cool. Next, we bring our hand to the air conditioner. Here you should feel the cold. If the air conditioner is still blowing room air, move on to the second reason.

The outdoor unit does not start

The air conditioner may not cool the air due to the lack of operation of the outdoor unit. Accordingly, we need to check its work. Today, most air conditioners operate silently, so ideally, you need to put your hand on the cover of the box of the outdoor unit. Here it would help if you felt the vibration and therefore look for the cause elsewhere. The operation of the outdoor unit of the air conditioner may also be hindered by the installed low-temperature (winter) kit. As a rule, such breakdowns cannot be repaired independently, and you should contact specialists.

The outdoor unit starts and stops

Often, the air conditioner’s external unit starts for a while and then turns off. The average operating time of the outdoor unit should be 70-85% and 15-30% in sleep mode. If the compressor is in standby mode more, then you need to look at the options: related to dirty filters and outer and inner sides.

This stage is to check the outdoor and indoor units for contamination. It is necessary to open the front cover and check the filters and the evaporator radiator of the indoor unit of the air conditioner. You should also check the outdoor unit’s evaporator for a layer of dust or poplar fluff. Think ahead about new HVAC supplies. The filters are easy to remove and can be washed under running water, while the outdoor unit and all consumables should be purchased separately. Then restart the system.

Too little or too much refrigerant

On average, up to 10% of the refrigerant is lost per year of using the air conditioner, even with a sealed system. There may not be enough refrigerant if the air conditioner has not been serviced for more than two years or the air conditioner has a refrigerant leak. If the air conditioner has not been serviced for a long time, it is worth contacting specialists for further technical service.

Often there is a refrigerant leak. It is caused by negligence and inexperience during installation. Due to a poor rolling connection, the freon comes out. If your air conditioner has been running for more than one season without problems, there is most likely no leak. If the operating time of the air conditioner is shorter, then you should contact the installer. In all other cases, you can not do without specialists. They will diagnose and determine the exact cause of the breakdown. If necessary, they will refuel with freon. If a refrigerant leak is detected, it is sealed.

In conclusion

Do not ignore the problem of poor air conditioning cooling. Minor faults are easily eliminated without requiring large expenditures. However, if you forget the inefficient operation of the device, you can wait for severe breakdowns. In this case, the repair will have to be decently spent. Follow the rules of operation and timely technical inspection of climatic devices. Experienced specialists from the service center will always help in solving this problem.
