An AC is an essential household appliance that absorbs heat and simultaneously provides cool air throughout your home. However, if your AC suddenly fails on a sweltering hot day, it can bring inconveniences and discomfort to your home. Moreover, ascertaining the cause of its failure can be complicated, and you need an AC repair service to rectify the problem. Therefore, you must employ an AC professional's service to inspect your system regularly and detect problems before they escalate. Below are signs that your system is failing and you need air conditioning repair.
Blowing Warm Air
If your AC blows warm air, it indicates a defective compressor or low refrigerant levels. If there is insufficient airflow into the AC, the coils can freeze, causing the compressor to strain in pressurizing the refrigerant. This causes the compressor to overheat, leading to warm air through the vents. Alternatively, a leak in the coolant line will restrict heat transfer, leading to warm air blowing out. Therefore, you should hire an AC repair technician to examine your unit, replace the compressor, and patch the coolant leaks for adequate cool air distribution in your home.
High Humidity Levels
Since the AC dehumidifies the incoming air in the cooling process, if your indoor atmosphere seems stuffy, your AC could be failing. The evaporator coils allow heat absorption as the refrigerant circulates, expelling heat and moisture. If clogged filters obstruct airflow into the AC, the coils will freeze, drastically increasing the humidity levels inside your house. An AC repair expert will clear away obstructions for proper airflow, thaw the ice on the coils, and integrate a whole-house dehumidifier into your AC for comfortable humidity levels.
Making Strange Noises
If your AC is making weird noises, it could be failing. Although the AC makes noise when starting up and shutting down, it could indicate a malfunctioning component if the noises become loud and unpleasant. For instance, a hissing sound will indicate a refrigerant leak, while a squealing noise will indicate a compressor belt failure. Since your AC unit will make distinct noises when a specific part fails, it is important that an AC repair expert determines the malfunctioning part and repair it for a quiet and effective function.
There is likely a problem when your AC runs for an extended period. Insufficient airflow can result from clogged air filters and blocked vents. This causes the AC to overwork to bring in sufficient air, hence running longer. Therefore, you should contact an AC technician to replace the used-up filters and clear obstruction in the vents.
Your AC will show indications of failure before it breaks down. You should schedule regular AC tune-ups to keep your unit in top condition and rectify the underlying issues amicably.
