Common AC Problems

When your AC blows warm air or makes unusual noises, it often points to a deeper issue. Pinpointing the cause is the first step toward a lasting solution. 

Common problems include:

• Refrigerant leaks. Refrigerant is the substance that absorbs heat from your home. When it leaks, cooling performance drops, and the compressor is forced to work overtime, which can lead to serious damage.
• Electrical control failure. Over time, components like capacitors, connections, and contacts can wear out or corrode, leading to inconsistent performance or a complete system shutdown.
• Clogged condensate drain. Your AC pulls moisture from the air, which exits through a drain line. If this line gets blocked by debris, water can back up, causing potential damage and triggering an automatic shutoff.
• Dirty coils. The indoor evaporator and outdoor condenser coils are critical for heat transfer. When coated in dirt or dust, their efficiency drops, forcing the system to run longer and work harder.

Our team has the skill to determine the root cause of the failure and get your system running smoothly again.

Signs You Need AC Service

Your air conditioner will almost always provide warning signs before it fails. Paying attention to these clues can help you address a small problem before it becomes a major, costly repair. 

If you notice any of the following, it is a good idea to call for a professional inspection:

• Warm air is blowing from vents. This is the most obvious sign that something is wrong. It could indicate anything from a simple thermostat issue to a serious compressor problem.
• Weak or no airflow. If the air from your vents feels weak, you may have a clogged air filter, blocked ductwork, or a failing blower motor.
• Strange noises. Grinding, squealing, or clanking sounds are not typical. These often point to mechanical issues that require immediate attention, like a loose part or a failing motor.
• Frequent cycling. An air conditioner that turns on and off more often than it should may be oversized for your home, low on refrigerant, or have a faulty thermostat.
• Unpleasant odors. A musty smell can signal mold or mildew growth within the unit or ductwork, while a burning smell could indicate a dangerous electrical problem.
