Air conditioning systems can stop working at the worst possible time, especially during hot Lake Balboa summers. Before scheduling a professional repair service, it is important to conduct a few simple checks. These steps can help identify minor issues that may not need expert intervention. This guide provides detailed instructions to troubleshoot your AC unit safely and efficiently before contacting local professionals.
Check the Thermostat Settings
Begin by reviewing your thermostat. Make sure it is set to “cool” mode and the temperature is set lower than the room temperature. Dead batteries in battery-powered thermostats can also stop the system from functioning. Replacing the batteries or resetting the thermostat may restore cooling.

Inspect the Circuit Breaker
If the AC unit does not turn on at all, inspect the circuit breaker panel. Locate the breaker connected to the air conditioner and check if it is in the “on” position. Tripped breakers can happen due to electrical surges or overloaded circuits. Switching the breaker back on may restart the unit. If the breaker trips again, this could indicate a larger electrical issue that needs a professional’s help.
Replace or Clean the Air Filter
Dirty filters can block airflow and cause the system to shut down or operate inefficiently. A clogged filter restricts air movement and may freeze the evaporator coil. If the air coming from the vents feels weak or warm, check the air filter and replace it if it appears dirty. Most filters should be changed every 30 to 90 days depending on usage and air quality in the area.
Examine the Outdoor Unit
Outdoor condenser units can become clogged with debris such as leaves, dirt, or grass. A blocked coil can cause the system to overheat or stop cooling. Turn off the power and inspect the unit for visible obstructions. Clear away debris and gently rinse the coil with a hose if necessary. Make sure the area around the unit has at least 2 feet of clearance on all sides for proper airflow.
Check the Air Vents
Blocked or closed air vents can disrupt airflow throughout your home. Walk through each room and ensure that all supply and return vents are open and unobstructed. Furniture or curtains covering the vents can reduce performance. Balanced airflow is essential for consistent indoor temperatures and system efficiency.
Inspect the Drain Line
Air conditioners produce moisture during the cooling process. This moisture drains through a condensate line. If this line becomes clogged, it may trigger a safety switch and shut off the system. Look for signs of water leakage or pooling near the indoor unit. If accessible, flush the drain line with warm water or a mild cleaning solution to remove blockages.
Reset the AC System
Sometimes a reset can resolve minor malfunctions. Turn off the system from the thermostat, wait five minutes, then restore power. This action allows the system’s internal sensors and control board to recalibrate. Many newer units also have a reset button on the outdoor unit. Pressing this button can restart the unit and clear temporary faults.
When to Contact Lake Balboa Pros
If none of the above steps restore cooling or the system keeps cycling on and off, it’s time to call a licensed HVAC technician. Strange noises, burning smells, leaking refrigerant, or repeated tripped breakers indicate complex problems. These issues require specialized tools and expertise for safe and accurate repair.

Why is my AC blowing warm air?
This could be due to low refrigerant, a dirty filter, a thermostat issue, or a frozen coil.
Can I pour bleach into the drain line to clean it?
A small amount of diluted bleach or vinegar can help prevent mold and blockages in the condensate drain line.
Should I reset the breaker if it trips frequently?
