As we return to work, we will prioritize the areas with the greatest need and best safety conditions. We will work hard to bring comfort as quickly and safely as possible!

Your family depends on air conditioning for temperature, humidity, and air quality control. When you need AC repair, your home can get downright uncomfortable. It’s important not to delay a repair, whether it’s a simple DIY fix or you need a technician. Below, we’ll detail how to troubleshoot your system, know when to call for help, and some common AC repair issues.

Troubleshooting Your Central AC

Some common issues you might be able to correct include:

  • The Condenser Doesn’t Turn On: Check whether the AC has power. If not, plug it in, switch the system on, or if the circuit breaker has tripped, reset it. Also, reset the thermostat if it’s set too high. However, other possible issues include a faulty compressor or motor.
  • The Condenser Unit Cycles to Often: If the condenser keeps turning on and off frequently, the condenser coil and fins may need to be cleaned. You may also need to clean the evaporator or remove grass, weeds, leaves, and other debris from around the unit.
  • The AC Is Cooling Unevenly: Check whether any vents are closed and open them, or clean or change the filter. It’s also possible the air distribution system may be out of balance. You’ll need an HVAC professional to inspect the ductwork and related components to see what to do.
  • There’s Not Enough Cool Air: The thermostat may be set too high, so lower the temperature. If the issue is caused by a dirty condenser or evaporator, clean the system, and if the condenser is blocked, remove debris. If any components are faulty or there’s not enough refrigerant, you’ll need a professional to address the problem.
  • Ice Forms in the AC Unit: Try operating the unit on the fan setting. The ice should melt and your system should work normally again soon. If the problem persists, there may be a fan problem, restricted airflow, or an issue with the coolant level.
  • There’s Low Air Pressure or Warm Air: Check the AC filter; if it’s dirty or clogged, replace it. See whether performance has improved once you’ve changed the filter and cleaned the system. If not, there’s likely an internal problem or the system isn’t the proper size.

Common Repair Issues

AC repair technicians tend to encounter a few common issues. Therefore, they are ready with the knowledge, tools, and parts to fix the issue when they arrive. Some of the most common air conditioner problems include:

Drainage Issues

Condensation forms as air is cooled in the system. High humidity can cause the drain pan to fill up and overflow, while a clog in the drain line can cause water to pool up on the floor. Excess condensation can lead to reduced performance and AC damage. A technician can clear clogs, treat the line to prevent algae growth, and perform other repairs.

Refrigerant Leak

AC refrigerant absorbs heat and transports it to components that release it outside. Low refrigerant levels typically mean there’s a leak and can overwork your air conditioner. Since coolant can be toxic to people and dangerous to the environment, you should call a professional ASAP to fix the problem. 

Faulty Compressor Fan

A malfunctioning or failed fan inhibits heat transfer. Aside from your home not getting cool, this can cause the compressor to overheat and fail, requiring major AC repair. At the very least, the system may keep shutting off because the fault triggers the safety controls. Repairing or replacing the fan is less expensive than installing a new compressor.

Frozen Coils

If the condenser coils keep freezing, there may be an airflow issue or obstruction such as a dirty filter or blocked return duct. Low refrigerant is another possibility. Therefore, it’s important to have the issue diagnosed and fixed by a skilled technician.

Leaky Ducts

Ventilation issues can cause cooled/treated air to escape from your home before it has a chance to cool rooms. This can reduce AC performance and efficiency. Holes and tears in ducts can also let outside air in, potentially causing pollution in your home including dust, mold, and viruses that can lead to a range of health issues. Professional duct sealing can quickly resolve small leaks and improve efficiency.
