Warning Signs Your AC Needs Repair: Identifying Common Issues and Solutions

Summer is here, and with it comes the scorching heat. Your air conditioning system becomes an essential part of your daily life during these hot months. However, incessant use might lead to wear and tear, causing multiple issues to arise. With this in mind, knowing the common signs that your AC needs repair is crucial to maintaining a comfortable and cool living space.

One common issue that can occur in air conditioning systems is a refrigerant leak, which would cause your AC to underperform and leave your rooms too warm. Recognizing the signs of low refrigerant levels, such as ice building up on the evaporator coil or hissing noise coming from the AC unit, can help you identify a potential leak. 

Stay tuned as we further discuss the most common air conditioning problems, their warning signs, and how our professionals can help fix them to ensure optimum comfort in your home. Early detection of issues can not only save you money on costly repairs but also prolong the life of your AC system.

1. Refrigerant Leaks and Low Levels

One of the most common AC problems is refrigerant leaks, which can cause your air conditioning system to work less efficiently. When refrigerant levels are low, your AC may struggle to cool your home, resulting in warm, uncomfortable rooms.

Warning Signs:

– Ice build-up on the evaporator coil

– Hissing or gurgling sounds coming from the AC unit

– Reduced cooling capacity

– Pools of liquid around the system, especially on hotter days


Our professionals can help identify and repair refrigerant leaks by inspecting your AC system, fixing any damaged parts, and properly recharging the refrigerant to the required levels. Remember, it’s essential to rely on trained technicians to handle refrigerant, which can be harmful to the environment if not appropriately dealt with.

2. Clogged Air Filters

Over time, air filters can accumulate dust, dirt, and other debris, which can restrict airflow and reduce your AC system’s efficiency. A clogged air filter also forces your unit to work harder to cool your home, increasing energy consumption and wearing the system down more quickly.

Warning Signs:

– Dusty air vents

– Increased indoor humidity levels

– Unusual or foul odors coming from the AC unit

– High energy bills


For optimal performance, it is recommended that you change your air filter regularly. Depending on the type of filter and your living conditions, replacement is usually recommended every 30 to 90 days. Our professionals can help you choose the right filter for your AC system and offer guidance on proper maintenance.

3. Electrical Problems

Electrical issues in your AC system can be dangerous if not addressed promptly. Wear and tear can cause electrical connections to loosen or malfunction, potentially leading to short circuits and even fires.

Warning Signs:

– Flickering lights when the AC is running

– Tripped circuit breakers

– Burning smells coming from the AC unit

– AC unit cycling on and off too frequently


To protect your AC system and ensure your safety, our technicians can perform scheduled electrical maintenance, which includes inspecting and tightening connections, checking the wiring, and ensuring safety switches are functioning correctly. If any electrical issues are detected, our professionals can diagnose and fix them before they cause more severe damage.

4. Malfunctioning Thermostat

A well-calibrated thermostat is essential for maintaining your home’s comfort levels. When it’s not working correctly, your AC system might underperform, resulting in uneven room temperatures and energy waste.

Warning Signs:

– Inaccurate temperature readings on the thermostat

– AC system running constantly or not running at all

– Unusually high utility bills

– Difficulty in setting the desired temperature


Our technicians can check your thermostat’s calibration, ensuring it accurately reads your home’s temperature. For older thermostats, upgrading to a programmable or smart thermostat can help you maintain better control over your AC system’s performance and energy efficiency, allowing you to set different comfort levels for different times of the day or days of the week.


Early detection of AC system problems is essential in preventing costly AC repairs in Clovis and ensuring you stay comfortable in your home. By paying attention to warning signs, such as refrigerant leaks, clogged air filters, electrical issues, and malfunctioning thermostats, you can take action to seek professional help before these issues escalate.
