When the humidity levels rise across the Mid-South, your air conditioning system is your primary line of defense against the sweltering heat. There is nothing more frustrating than walking into your living room only to find that your vents are pushing out lukewarm air instead of a refreshing breeze.
At AirMasters Air Conditioning & Heating, our team of 21 highly trained professionals has spent over 25 years diagnosing this specific issue for property owners throughout Shelby County. While it might be tempting to ignore a slight temperature change, warm air is often a warning sign that your system is under significant mechanical stress.
Troubleshooting Your Thermostat and Power Supply
Before assuming you have a major mechanical failure, the first step is to check the simplest components of your HVAC system. It is surprisingly common for a thermostat to be accidentally switched to a setting that prevents proper cooling.
Check the Fan Setting: Ensure your thermostat is set to "Auto" rather than "On." The "On" setting keeps the fan running even when the AC isn't cooling, which eventually blows room-temperature air through your vents.
Inspect the Circuit Breaker: Your AC system has two main parts. If the breaker for the outdoor unit trips, the indoor fan will still blow, but it won't be able to remove any heat from your home.
Verify the Mode: It sounds simple, but double-check that the system hasn't been bumped into "Heat" or "Fan" mode during a seasonal transition.
The Impact of Restricted Airflow and Clogged Filters
One of the most frequent causes of inadequate cooling is a lack of proper maintenance, specifically regarding air filters. When a filter becomes clogged with dust, pet hair, and Memphis pollen, it restricts the volume of air flowing over the evaporator coil.
This restriction can cause the coil to freeze over, effectively blocking the cooling process. At AirMasters Air Conditioning & Heating, we emphasize that a simple monthly filter check is one of the most effective ways to prevent your system from working harder than it should. If your system is struggling to pull in air, it places an immense strain on the motor, which can lead to expensive repairs if the restriction isn't addressed promptly.
Identifying Refrigerant Leaks and Coil Issues
If your thermostat is set correctly and your filters are clean, but you are still experiencing warm air, you may be dealing with a refrigerant leak. Refrigerant is the lifeblood of your AC system, responsible for absorbing heat from your indoor air and carrying it outside.
Hissing Sounds: If you hear a faint whistling or hissing near your indoor or outdoor units, it often indicates gas escaping from the refrigerant lines.
Ice Accumulation: Low refrigerant levels cause the temperature of the coil to drop too low, leading to ice buildup even on a hot day.
High Utility Bills: When refrigerant is low, the system runs longer to try and reach the target temperature, causing a spike in energy consumption.
