Most homeowners don’t notice anything wrong with their air conditioning system until it fails to perform when it is needed. Perhaps it is 95°F outside and you need to cool down, but there is just something wrong with the air conditioner. It’s always a good idea to be familiar with your air conditioning unit and some common issues so that you can call professionals if the situation requires.
Over time, your air conditioner’s filter will undoubtedly accumulate dirt and debris. Homeowners, however, should never let it get to a point where the system develops a clog. Airflow will be restricted, reducing your air conditioner’s ability to efficiently and effectively cool the air. Usage and indoor conditions play a large part in determining how quickly the filter gets dirty. If the unit runs constantly or if you have pets, it can happen quicker. To avoid this, inspect your filter regularly and replace it at least once a month, especially when it is heavily used.
Sensor ProblemsA thermostat sensor is an inherent part of an air conditioning unit. If your air conditioner behaves erratically in terms of temperature, this may be the culprit. Sensors are usually located behind the control panel near the evaporative coil. Gently adjusting the position of the sensor by bending the wire holding it in place might do the trick, but be careful not to tamper with it too much. When in doubt, always seek professional help.
A refrigerant is a fluid used in the cooling cycle. There are two main causes for a low refrigerant level: undercharged at installation or leakage. Low refrigerant charge level decreases your air conditioner’s performance and efficiency. It should be charged to a level that matches the manufacturer’s specification. In case of a leak, you can’t simply refill the refrigerant. Call a trained technician to fix the leak and refill the refrigerant to the correct amount. Remember, refrigerant leaks can be harmful to the environment. Only a qualified technician should handle this.
Maintenance is an important but often overlooked part of air conditioning care. Technicians will perform many tests and check-ups, as well as thoroughly cleaning your air conditioning system to ensure optimum performance. Inadequate maintenance brings a number of potential problems, starting from faulty temperatures to premature damage to the compressor or fans. Scheduling annual inspection and maintenance helps preserve the lifespan of your air conditioner.
Air conditioning problems can be prevented by cleaning your filters and performing timely maintenance. If it does break down, call an air conditioning repair company promptly.
