One of the most frequent air conditioning problems is inadequate cooling. This issue occurs when the AC unit fails to lower the temperature to the desired level, leaving the indoor space uncomfortably warm. Several factors can contribute to inadequate cooling, including dirty air filters, refrigerant leaks, or compressor malfunctions. Here are common AC problems that can cause inadequate cooling and be treated by an air conditioning service:
Refrigerant Leaks
Causes of inadequate cooling include improper installation, wear and tear on the refrigerant lines, and factory defects. When a refrigerant leak occurs, it can result in a decrease in the level of refrigerant within the AC system. The air conditioner’s cooling capacity is significantly reduced, making it challenging for the unit to cool the space effectively. This may result in longer run times and refrigerant, which can cause the air conditioner to struggle to reach the desired temperature. Engage a qualified HVAC technician to locate and identify the cause of the leak using their specialized tools and techniques. Once they detect the leak, they will complete the repair using epoxy sealing, soldering, or replacing the damaged components.
Electric Control Failure
Electronic control failure can be caused by a damaged electrical wire, incorrect voltage, or faulty circuit boards. Electric control failure can lead to the AC unit working incorrectly or shutting down. Work with an air conditioning service specialist to inspect the electrical components of the system. They can identify any damaged wires and replace them to rectify the problem. Regular air conditioning maintenance can help prevent this problem. During routine inspections, experts can detect potential electrical problems early, allowing timely repairs and avoiding more severe issues.
Faulty Sensor
Air conditioners are equipped with a thermostat sensor behind the control panel. This sensor is responsible for measuring the temperature of the air as it enters the evaporative coil. If the sensor is improperly positioned, it can lead to constant cycling of the air conditioner. The sensor should be located near the coil but not in direct contact with it. To address this issue, perform regular maintenance, including cleaning and keeping the sensors free from dust and dirt.
Loud Noises
A loud AC unit can be caused by the collection of dirt, dust, and debris inside the machine. The buildup can lead to buzzing or vibrating sounds. Imbalanced fan blades, loose panels, or unbalanced blowers can also contribute to the noise. If ignored, the problem may worsen, resulting in more significant damage. HVAC experts can help remove that noise while working on the underlying issue. They can also help in tightening or replacing broken parts. In cases where engines and fan blades are imbalanced, technicians can balance or replace the affected components to restore proper operation.
Frozen Coils
Restricted airflow can prevent proper heat transfer and lead to the accumulation of condensation on the coils, which then freeze. Frozen coils may cause the system to struggle to cool the air resulting in reduced air conditioning. Reduced air caused by frozen coils can put extra strain on the compressor, potentially leading to its failure over time. To prevent this problem, you can check and clean the air filters. Inspect the ductwork for any blockages and leaks inhibiting proper airflow.
Faulty Compressor
Low refrigerant levels and electrical failures are the common causes of compressor failure. A faulty compressor may gradually lose cooling power over time as the refrigerant charge decreases. To address a faulty compressor, look for the root cause of the problem. Low refrigerant levels can be resolved by fixing or locating leaks and recharging the system.
