If your AC isn’t keeping your home as cool as it should, it may be suffering from poor cooling performance. This problem can make some rooms uncomfortable while others remain too warm.

Common signs and causes include:

• The air coming from the vents isn’t as cold as it should be.
• Some rooms are cooler than others, indicating uneven cooling.
• Dirty filters are restricting airflow and reducing cooling efficiency.
• Low refrigerant levels can prevent the system from reaching the desired temperature.
• Blocked vents or failing compressors can also impact performance.

Quick Troubleshooting Tip:

Check and replace filters and ensure that all vents are open.

Even with these basic checks, persistent poor cooling often requires a professional to safely diagnose and repair the system.

Unusual sounds from your air conditioner are often a warning that something is wrong. Buzzing, rattling, grinding, or hissing noises should never be ignored.

Common causes include:

• Loose components within the unit.
• Worn-out motors or bearings.
• Refrigerant leaks create hissing or bubbling sounds.

Quick Troubleshooting Tip:

Listen carefully to identify the location of the noise, but avoid opening the unit yourself.

Persistent or loud noises should always be inspected by a professional to prevent further damage.

Water pooling around your indoor unit is a clear sign that your AC isn’t draining properly. Leaks can cause damage to floors, walls, and ceilings if not addressed quickly.

Possible causes include:

• A clogged condensate drain prevents water from leaving the system.
• Frozen evaporator coils that thaw and drip onto surfaces.
• A damaged or rusted drain pan.

Quick Troubleshooting Tip:

Turn off your air conditioner to prevent water damage, and do not attempt to dismantle the unit yourself.

A licensed technician can safely clear clogs and repair any damaged components to stop leaks.

Electrical problems can prevent your AC from turning on or cause frequent tripping of breakers. These issues are not only inconvenient but can be dangerous if handled incorrectly.

Common causes include:

• Faulty wiring within the unit or home.
• Damaged capacitors that affect startup and operation.
• Tripped breakers caused by overloads or short circuits.

Safety Note:

Electrical repairs are extremely hazardous, and attempting them yourself can result in injury or further damage. Call a professional immediately.

While some minor air conditioner issues can be addressed by homeowners, most problems require the expertise of a licensed technician. Understanding what you can safely troubleshoot versus what should be left to professionals is essential for protecting your home, your AC system, and your safety.

There are a few simple checks that you can perform without risking damage or injury. These include:

• You can check and replace your air filters to improve airflow and cooling efficiency.
• You can make sure all vents and registers are open and unblocked.
• You can verify that your thermostat settings are correct and functioning properly.
• You can check your circuit breakers to see if a tripped breaker is preventing your AC from running.
• You can clear any overgrown foliage or debris that is located near your outside AC unit.

These basic steps may solve minor issues, such as reduced airflow or uneven cooling, but they do not address deeper mechanical, electrical, or refrigerant problems.

Knowing when to call a professional for air conditioner repair is crucial to protect your home, ensure your system operates efficiently, and keep your family safe. While some minor issues can be resolved with basic troubleshooting, certain signs indicate that immediate expert attention is required.

If you notice any of the following issues, it’s time to stop troubleshooting and call a licensed technician:

• Your air conditioner won’t turn on at all, even after checking circuit breakers and thermostat settings.
• Unusual or loud noises persist after basic checks, indicating possible mechanical or electrical issues.
• Water is leaking from your AC unit, which could cause damage to floors, walls, or ceilings.
• Your air conditioner continues to provide poor cooling, even after replacing filters and checking vents.
• You detect burning smells or experience frequent electrical breaker trips, which are serious safety concerns.

These problems are not only inconvenient but can lead to costly repairs or safety hazards if left unaddressed.

Regular maintenance can help keep your air conditioner running efficiently, reduce the likelihood of costly repairs, and extend the life of your system. While professional inspections are essential, there are simple steps you can take to help your AC perform at its best.

Even with professional service, these routine tasks can make a noticeable difference in your AC’s performance:

• Replace or clean air filters every 1–3 months to maintain proper airflow and cooling efficiency.
• Keep vents and registers clear of furniture, curtains, or other obstructions to allow air to circulate freely.
• Maintain proper thermostat settings to reduce unnecessary strain on your system.
• Keep the outdoor unit free of debris, leaves, and vegetation that could block airflow.
• Schedule annual professional tune-ups to inspect refrigerant levels, electrical components, and overall system performance.

Performing these simple steps can help prevent common problems and keep your home comfortable all summer long.
