During the hot months, your HVAC system plays a significant role as it helps maintain an
optimal and comfortable temperature. Without proper maintenance, issues can arise, which
might leave the AC in your home in Charleston, SC, struggling. Here are seven of the most
common reasons for AC repairs to your HVAC system.
1. Refrigerant Leaks
If your HVAC system is low on refrigerant, it could be either as a result of leaks or because of
undercharging during installation. If your system has a leak, adding refrigerant may not be an
appropriate solution. The leak will need to be fixed and then the system can be recharged.
An experienced technician will determine if the leak is fixable.
That is why you need to find a professional HVAC technician to help. A trained technician will
identify the issue and fix any leaks as well as charge the air conditioning with the appropriate amount of
refrigerant. To achieve peak efficiency, keep in mind that your system’s refrigerant shouldn’t be
either undercharged or overcharged.
2. Outdoor Fan Problems
The primary function of the outdoor fan is to disburse heat from inside your house to the
outside. A faulty outdoor fan can prevent efficient heat transfer. A lack of heat transfer will
affect the cooling ability of your system and affect your system’s efficiency.
3. Sensor Issues
Some systems have a built-in thermostat sensor. If the sensor is not functioning the way it
should, it might not be able to measure the air entering the evaporator coils correctly.
Ideally, the sensor should be close to the coil but not in contact with it. A trained technician can
help check your system and adjust the sensor’s position.
When wires combine with moisture, corrosion can happen. Corrosion affects terminals and
wires related to your AC system, and this will make your AC turn on and off.
Typically, corrosion makes your AC struggle to achieve its optimal functionality. It might also
lead to your system coming to a complete stop.
5. Clogged Drains
During normal functioning, your air conditioner removes moisture from the air that needs to go
somewhere. The condensed water should travel via a drain line into the pan and eventually
down a pipe that drains outside of your home.
If the pan is full or the drain clogged, the condensation can accumulate in the drain pan and
overflow to damage a floor, ceiling and stop your AC system from cooling.
6. Frozen Evaporator Coils
Your system’s evaporator coils are responsible for capturing heat from the air. For proper heat
flow, the coils require warm air moving around them. If the evaporator coils get extremely cold
for whatever reason, something wrong might be happening to the airflow.
Too much cold on the coils can create a layer of ice on the outside of the coils. Frozen air coils
can result in the transfer of warm air or very little air from the supply registers.
7. Dirt and Debris
Every part of your AC system must be clean for it to function the right way. Evaporator coils, air
filters, and electric panels must be free from dirt and debris. Too much dust and dirt coating
specific areas of your system can reduce your system’s efficiency as well as pump allergens and
dust into your home.
When your system is not working at its peak efficiency, you might not achieve your intended
home comfort. On the other hand, allergens can cause severe health issues for you and your
family. It’s important to keep all of the system’s components clean to ensure it is functioning
