Nothing is worse than coming home from a stressful day at the office to discover the house is sweltering hot. When your air conditioner is no longer functioning properly, it's disheartening especially when the weather is so hot. To understand why air conditioners suddenly stop working, let’s review the 3 most common causes of A/C malfunctioning.
Lack of Proper Maintenance
It sounds improbable, but it’s often the case. Air conditioners begin to malfunction when they haven’t been maintained properly. That means it doesn’t receive annual inspections or regular filter changes. Inspections are important because the service technician can often stop a problem before it starts. Filter changes are necessary to keep the air flowing. Just like with any piece of machinery, it needs regular check-ups and cleaning.
Lack of Refrigerant
If you are low on refrigerant, your air will not blow cold air. Having a service technician fill up your unit up with refrigerant will cool your house down but it rarely solves the main problem. You will only experience a loss of refrigerant if there is a leak or the unit didn’t have enough refrigerant to start with.
Air conditioners rely on a thermostat to tell it when the room is the proper temperature. Within the thermostat is a sensor, which indicates when the thermostat should turn on or turn off. If the sensor is malfunctioning it won’t read the temperature right and you will have an air conditioner that won’t turn on or off when it’s supposed to.
While there are other reasons an air conditioner may fail to work properly, these are some of the most common. If you need a reputable heating and cooling professional, contact the team at AJR Heating, Air Conditioning, and Refrigeration today.
