Common Causes of AC Repair Issues

Air conditioners are an essential part of modern life, providing relief from hot and humid weather conditions. However, like any mechanical system, air conditioners can experience problems and breakdowns that require repair.

These issues can cause the AC unit to work harder, resulting in inefficient cooling and higher energy bills. Regular maintenance and timely repair by a professional AC repair technician can help prevent these problems and ensure your air conditioner operates efficiently.  

Common A/C Issues

Homeowners may encounter several common causes of air conditioner repair issues. These include:

Clogged air filters
Air filters are a critical component of air conditioning systems, as they help remove dust, dirt, and other airborne particles from the air before circulating throughout the home. Over time, these filters can become clogged with dust and debris, which can restrict air flow and cause the AC unit to work harder to circulate air. If left unchecked, clogged air filters can cause the AC unit to overheat and potentially lead to system failure. This can lead to various problems, including reduced cooling capacity, higher energy bills, and increased wear and tear on the AC unit.

Low refrigerant levels
Refrigerant is responsible for absorbing heat from indoor air and transferring it outside, which cools the air inside the home. If the refrigerant levels in the AC unit are low, the system cannot cool the air effectively. This can be caused by leaks in the refrigerant lines or components, such as the evaporator coil or condenser. Low refrigerant levels can reduce cooling capacity, increase energy bills, and even damage the AC unit if the compressor overheats.

Faulty capacitors or fan motors
Capacitors store and release electrical energy to start fan motors, which circulate the air and cool the home. Over time, these components can wear out, become damaged, or fail, leading to problems with the AC unit. A faulty capacitor can cause the fan motor to start slowly, make unusual noises, or fail to start. A defective fan motor can reduce cooling capacity, increase energy bills, or complete system failure.

Leaking ducts
Sealing leaks in the ductwork can improve the efficiency of the AC system, reduce energy bills, and improve indoor air quality. If there are leaks in the ductwork, cooled air can escape into the attic or crawl space rather than reaching the home’s living areas. This can result in inefficient cooling, higher energy bills, and reduced comfort. Leaking ducts can also allow contaminants, such as dust, dirt, and allergens, to enter the home’s living spaces, impacting indoor air quality and potentially causing health problems.

Electrical problems
Electrical problems can be a significant issue for air conditioning systems, as the AC unit requires electricity. Various issues can cause electrical problems, including faulty wiring, damaged components, or electrical surges. These problems can result in the AC unit not turning on or failing to function correctly, leading to reduced cooling capacity, higher energy bills, and even damage to the system. Electrical problems can also create a safety hazard, as faulty wiring or components can increase the risk of electrical shock or fire.

Dirty coils
Dirty coils can cause a range of problems for air conditioning systems. The evaporator and condenser coils are critical components of the AC unit, as they help to remove heat from the air and transfer it outside. If these coils become dirty, they can restrict airflow and reduce the AC system’s cooling capacity. Dirty coils can also cause the AC unit to work harder, leading to higher energy bills and increased wear and tear on the system. Over time, dirty coils can cause damage to the AC unit, including compressor failure, which can be costly to repair.

Thermostat issues
Thermostat issues can be a problem for air conditioning systems because they regulate the home’s temperature. If the thermostat is not functioning correctly, it can result in the AC unit not turning on or off when it should, leading to inefficient cooling, higher energy bills, and reduced comfort. For example, if the thermostat is malfunctioning, it may not accurately sense the temperature in the home, leading to the AC unit turning on and off unnecessarily, which can be inefficient and costly.
