5 Common Central AC Repair Issues Every Homeowner Should Know

Central air conditioning is a modern marvel in home comfort, but like any complex system, it’s prone to various problems over time. Unfortunately, when your central AC system malfunctions, it’s often not just a matter of comfort; it can also impact your home’s energy bill and air quality. Understanding the common issues with central AC units can help homeowners identify problems early and seek solutions before the system suffers significant damage. Call for a central AC repair in Mason if you experience any of the following common issues:

1. Refrigerant Leaks

Refrigerant is the lifeblood of your air conditioning system. It’s responsible for cooling the air and removing humidity, making leaks a serious concern. Signs of a refrigerant leak include ice accumulating on the evaporator coil or decreased cooling efficiency. If you notice these symptoms, call a professional HVAC technician. Attempting to replenish refrigerant can be dangerous and is best left to those with the right training and equipment.

2. Sensor and Thermostat Problems

The thermostat communicates your desired cooling level to the AC unit. If the thermostat is faulty, it can lead to inconsistent temperatures or the AC not turning on when it should. Additionally, a thermostat sensor on the AC’s evaporator coil can cause similar issues if knocked out of position.

3. Drainage Issues

Your central AC system’s primary job is to remove humidity from the air. Condensation collects in the drip pan and is drained away. However, if the drain becomes clogged, the drip pan will fill up, potentially overflowing and damaging the surrounding areas.

4. Electric Control Failure

The compressor and the fan in your AC system rely on electrical connections. Over time, switches and relays may wear out and require replacement. If your AC is frequently turning on and off, also known as short cycling, it’s a good indication that there may be an issue with the controls.

5. Compressor and Fan Issues

The compressor circulates the refrigerant through the AC system while the fan blows over the condenser and evaporator coils, releasing or absorbing heat. If you hear grinding or squealing noises from the AC, it could be a sign that the fan or compressor is failing.

Understanding the components of your central AC system and being aware of potential issues is the first step to keeping your home cool and comfortable. Regular maintenance, including annual inspections by a professional, can help prevent many problems before they start. However, if you notice any of the issues above, don’t hesitate to contact an HVAC technician.
