Air conditioners commonly face performance issues that can hinder their effectiveness, which requires immediate AC repair. In the case of central air conditioning systems, problems often occur when rooms are closed off or there are obstacles to proper airflow throughout the house.
To address this, it’s crucial to close windows and outside doors, effectively isolating a room or connected rooms from the rest of the house as much as possible. By taking these measures, you can optimize the performance of your air conditioner.
Air conditioners can experience common problems due to faulty installation, insufficient maintenance, and inadequate service procedures. When a central air conditioner is improperly installed, it can lead to duct leaks and reduced airflow.
Another issue arises when the amount of refrigerant in the system, known as the refrigerant charge, doesn’t follow the manufacturer’s specifications. This discrepancy can have a negative impact on the unit’s performance and efficiency.
Unfortunately, unqualified air conditioning contractors that offer AC repair in Knoxville TN may overlook refrigerant charging issues or exacerbate existing issues by adding refrigerant to a system that is already full. When seeking a technician to maintain your air conditioner, it’s essential to ask the right questions and assess their expertise to ensure optimal service.
Air conditioner manufacturers are known for crafting long-lasting, high-quality products. If your AC unit malfunctions, begin troubleshooting by examining the fuses or circuit breakers. Give the unit around five minutes to cool down before resetting any breakers.
On a scorching hot day, if the compressor of a central air conditioner suddenly stops, it might be due to the high-pressure limit switch being triggered. You can attempt to reset it by pressing the button found in the compressor’s access panel.
Problems That Need AC Repair
Low refrigerant levels in your air conditioner can be due to undercharging during installation or a leak. Simply adding refrigerant is not a solution if there’s a leak. A trained and certified technician should fix any leaks, test the repair, and then charge the system with the correct amount of refrigerant.
Remember, your air conditioner performs best when the refrigerant charge is the same as the manufacturer’s specifications precisely—neither overcharged nor undercharged. Refrigerant leaks could also be detrimental to the environment.
Neglecting to clean filters and air conditioning coils can impair the proper functioning of your air conditioner and cause premature failure of the compressor or fans.
Electric Control Failure
The compressor and fan controls can wear out, especially if the air conditioner frequently turns on and off, which often happens when a system is oversized. Corrosion of wires and terminals is also a common issue in many systems, so electrical connections and contacts should be inspected by air conditioning contractors such as J.C. Heating & Air during professional service calls.
Room air conditioners have a thermostat sensor located behind the control panel that measures the temperature of the air entering the evaporative coil.
If the sensor has been displaced, the air conditioner may behave erratically or cycle constantly. The sensor must be placed near the coil but not touching it. Adjust its placement by bending the wire that holds it in position carefully.
During humid weather, inspect the condensate drain to make sure it’s not clogged and is properly draining. Room air conditioners may not drain correctly if they are not mounted level.
