How to Troubleshoot Common Air Conditioning Problems
Are you having problems with your AC? Here is how to solve some of the most common problems!
AC repair in Houston can be needed at any time, as an air conditioner can break down for many reasons. How to deal with a breakdown, or better yet, prevent it from happening? For this purpose, it is necessary to know what kind of malfunctions happen with your climate control equipment and what they can be caused by.
The Conditioner Does Not Switch On/ Does Not Switch Off
There can be a lot of reasons for this problem. The most simple – is in the remote control, the batteries are dead. In this case, a simple change of batteries will help. Probably, rebooting the device will help to solve the problem. It is also possible that the filters are clogged. In this case, remove the top panel, and look into the filters. If they are dirty, gently wipe them with a soft damp cloth. To avoid the problem, wash the filters once every 3 to 4 weeks.
Improper installation is a common cause of the failure of air conditioning equipment. Contact an expert to correct the errors. Sometimes the unit may not turn off. The problem is most often caused by batteries or a faulty remote control. But if it does not turn off even after pressing the button on the body, you need the help of a repairman.
Problems with the Temperature Sensor
If the sensor constantly displays inappropriate values or incorrectly selects the time of operation in the active mode of the air conditioner, the room may be too cold or too hot. Such a malfunction can lead to a permanent failure of the air conditioner, so you need to fix it immediately.
There are two possible solutions to the problem:
- Turn off the air conditioner and power, using the switch on the main electrical panel, and remove the plug from the outlet.
- Open the compartment in which the evaporator of the air conditioner indoor unit is located. Install the temperature sensor close to the coil for maximum accuracy. If it is too close to the coil or touches it at all, the temperature will be overestimated; if it is too far away, it will be underestimated. All this leads to errors in the operation of the device. You can fix the problem yourself by carefully bending the sensor in the right direction.
After that, put the air conditioner back together and do a test run. If the problem is only in a sensor, climate techniques will work as they should. If the conditioner continues to malfunction, switch it off and call a master – the repair requires special skills and tools.
Lack of Freon
A frozen inlet valve to the outdoor unit is a definite sign of a lack of refrigerant in the system. It leads to the deterioration of air conditioner performance and insufficient cooling of the room. In addition, the overall performance of the climate equipment decreases. Such a problem can be caused by freon leakage from the system.
It can be determined both by a bad smell from the place where the device is installed and by the fill scale if your air conditioner model has one. The amount and type of freon are determined by the manufacturer and must comply with the datasheet of the specific model. If you find a leakage, you must immediately turn off the air conditioner and call a technician – the refrigerant is harmful to human health.
