When your AC unit starts to fail in the middle of a hot Rockwall, TX summer, it can turn your home into an uncomfortable, sweltering space. Whether your air conditioner is blowing warm air, making strange noises, or just not cooling like it used to, a failing AC can quickly ruin your comfort. Here’s what you should do if your AC is no longer keeping your home cool.
Check for Common Issues Before Calling a Technician
If your AC unit isn’t cooling your home properly, the first step is to check for simple problems that could be easily fixed. Start by inspecting your thermostat. Sometimes, the issue is as straightforward as the thermostat being incorrectly set. Ensure it’s set to “cool” and that the temperature is lower than the current indoor temperature. If your thermostat runs on batteries, try replacing them, as old batteries can prevent the system from turning on properly.
Next, take a look at your air filter. A clogged or dirty air filter is one of the most common reasons why AC units fail to cool effectively. When filters get clogged with dust and debris, airflow is restricted, causing the system to overheat and underperform. This can lead to poor cooling and even cause the unit to shut down altogether. Changing the air filter every 1-3 months is a simple but important step in maintaining your system’s efficiency. A clean filter can instantly improve airflow and restore your AC’s cooling ability.
Another issue that can cause your AC to stop working is a tripped circuit breaker. Air conditioners require a lot of power to run, and a power surge or overload can cause the breaker to trip. Check your home’s electrical panel to see if the breaker that controls your AC has been tripped. If it has, reset it and try turning your AC on again. If the breaker keeps tripping, there may be an underlying electrical issue that requires professional repair.
Listen for Unusual Noises
If your AC unit is making strange noises, it’s often a sign that something is wrong inside the system. Banging, rattling, squealing, or grinding sounds could indicate loose or broken parts, such as a failing motor or compressor. Running your AC when it’s making these noises can cause further damage, so it’s best to turn the system off and schedule an inspection with a licensed HVAC technician. Catching these issues early can prevent expensive repairs or a full system replacement.
Strange noises also signal that your AC might be working harder than it should, leading to higher energy bills and reduced efficiency. By addressing the issue quickly, you can save money on repairs and improve the overall performance of your unit.
Watch for Refrigerant Leaks
If your AC is running but isn’t effectively cooling your home, a refrigerant leak could be the cause. Refrigerant is essential for the cooling process, and when there’s a leak, the system can’t cool the air properly. This often results in warm air coming from your vents or uneven cooling throughout your home.
Refrigerant leaks require professional attention and should not be handled as a DIY project. A licensed HVAC technician can detect the source of the leak, repair it, and recharge your system with the appropriate amount of refrigerant. Continuing to run your AC with low refrigerant levels can cause more damage to the system, leading to more expensive repairs.
Consider Replacing an Aging AC Unit
While many AC issues can be repaired, if your unit is over 10-15 years old and requires frequent repairs, it may be time to consider a replacement. An aging AC unit is less efficient, resulting in higher energy bills and more frequent breakdowns. Investing in a new, energy-efficient AC unit can save you money in the long run by reducing repair costs and lowering your monthly utility bills.
Modern AC systems are designed with advanced energy-saving features that allow them to cool your home more effectively while using less energy. Many new units are also compatible with smart thermostats, giving you greater control over your home’s temperature and improving overall efficiency.
- Check thermostat settings: A simple adjustment or battery change can sometimes resolve the issue.
- Inspect air filters: Clogged filters can restrict airflow, causing the system to overheat and reduce efficiency.
- Look for refrigerant leaks: Low refrigerant levels can prevent your AC from cooling effectively and require professional repair.
- Listen for unusual sounds: Noises like banging or squealing can indicate mechanical problems that need immediate attention.
- Consider replacement for older units: If your system is old and requires constant repairs, a new, energy-efficient unit might be the best solution.
