5 Signs To Call For Air Conditioning Repair Services
During the warmer months of the year, a functional air conditioning system works efficiently to boost indoor comfort. If your AC unit has underlying issues, hire a qualified HVAC technician to inspect and fix it. Here are five signs that indicate you need to call for air conditioning repair services:
1. Lack of Cool Air
If your air conditioner is running but not producing cool air, several issues could be causing the problem. The compressor circulates refrigerant and pressurizes it to facilitate heat exchange. If the compressor is malfunctioning, the cooling process may not occur.
A clogged air filter can restrict airflow, causing the system to struggle to cool the air effectively. If the refrigerant levels in the air conditioner are low, the cooling capacity decreases. A technician can refill the refrigerant to boost effective and efficient AC functioning. The expert can also change air filters and fix faulty electrical components that can contribute to compressor failure.
2. Frequent Cycling
Frequent cycling can lead to issues such as increased wear and tear on the system and higher energy bills. A malfunctioning thermostat or a thermostat positioned near a heat source can cause the system to turn on and off constantly. The thermostat may be sensing incorrect temperatures, leading to improper cycling. A technician can recalibrate or replace the thermostat for accurate temperature sensing and preventing frequent cycling by the AC system.
Blocked or closed vents can interrupt the airflow balance in the system, leading to uneven cooling. This imbalance can cause the system to cycle more frequently as it tries to maintain a consistent temperature. If the evaporator and condenser coils are blocked, it can hinder the heat exchange process, leading to more frequent cycles. Cleaning these AC components can remove obstructions and promote enhanced function.
3. Peculiar Smells
Strange odors from your cooling system could be a sign to call for air conditioning repair services. Mold can thrive in damp or dark areas, such as the evaporator coil or drip pan, contributing to musty smells. A burning smell may indicate an electrical issue, such as a burnt-out wire or a malfunctioning component.
Sometimes, foreign objects can find their way into the HVAC system, causing strange odors. A technician can inspect and remove unwanted materials to eliminate the odors. If the drain pan is clogged, standing water becomes a breeding ground for mold and bacteria, causing unpleasant odors.
4. Unusual Noises
Different types of unusual noises from your air conditioning system may indicate specific mechanical issues that require attention. If your AC produces banging sounds, a broken or unbalanced fan blade or loose hardware could be causing the problem. Rattling noises may occur due to loose components, debris in the system, or a failing motor.
Buzzing noises may emanate from loose parts, electrical issues, or debris in the cooling system. Hissing or whistling sounds may indicate a refrigerant leak. When you hear such noises, hire a technician to inspect and repair the AC components causing the problem.
5. Constant Ice on the Unit
Low refrigerant levels can cause the evaporator coils to operate at a temperature below the dew point, leading to the formation of ice. A qualified technician can recharge the system or identify and repair refrigerant leaks. A malfunctioning expansion valve can cause irregular refrigerant flow, leading to ice formation. Repairing the expansion valve can resolve the issue and boost your AC unit’s performance.
A malfunctioning blower motor can reduce airflow over the evaporator coils, leading to ice formation. Regular maintenance and prompt repairs can address issues with the blower motor.
