Why Isn't My Home's AC Cooling to the Set Temp?

When your AC unit starts showing signs of wear and tear or starts having issues, you might find yourself at a crossroads: Should you repair it or replace it altogether? We can help!

Living in the Treasure Coast area of Florida, a properly functioning air conditioning system is paramount for home comfort. As temperatures soar and humidity levels rise, ensuring your home remains a cool and comfortable oasis becomes a top priority. However, the frustration sets in when homeowners discover that their air conditioning units are not effectively reaching the desired set temperature. In this article, we delve into the details of common issues that might be hindering your AC's performance, offering insights into troubleshooting and solutions to restore optimal cooling comfort to your living space. Illustrating the problem at hand: Imagine your indoor temperature stands at 82°F. Despite setting your home's thermostat to a comfortable 74°F, several hours later, the indoor temperature has only decreased to 78°F. Clearly, when your thermostat setting doesn't align with your home's temperature, there is an issue that needs attention. So what are some reasons why this could be happening? Air Filter Neglect A common culprit for inadequate cooling is a neglected air filter. In the Florida climate, where the AC often works overtime, filters can quickly become clogged with dust and debris. A dirty filter restricts airflow, making the cooling system less efficient. Regularly changing or cleaning the air filter is a simple yet effective solution to ensure optimal performance. Thermostat Issues Sometimes, the issue lies with the thermostat itself. Incorrect settings, faulty sensors, or outdated thermostats can mislead your AC into working inefficiently. An air conditioning contractor can assess and recalibrate your thermostat, ensuring it accurately reflects your desired temperature and communicates effectively with the cooling system. A Refrigerant Leak Low refrigerant levels can significantly impact your AC's ability to cool. The Florida heat can put additional stress on the system, causing refrigerant levels to drop. If you notice a decrease in cooling performance, it's crucial to have a professional air conditioning contractor inspect and replenish refrigerant levels to restore your system's efficiency. Some signs of a refrigerant leak that you may be able to identify yourself: Formation of ice on refrigerant lines Freezing of the evaporator coil Audible hissing or whistling noises emanating from refrigerant lines If you do notice any of these signs, it’s important to call in a professional to conduct a thorough inspection to pinpoint and address the source of the refrigerant leak. Once the source of the leak has been located and repaired, they’ll be able to recharge your system with the proper amount of refrigerant to restore optimal performance. Inadequate Insulation Florida's heat can be relentless, and if your home lacks proper insulation, it becomes challenging for your AC to maintain the desired temperature. An air conditioning contractor can evaluate your home's insulation and recommend improvements to help your cooling system work more effectively, keeping the warm air outside where it belongs. Ductwork Leaks Leaky ducts can undermine your AC's performance by allowing cooled air to escape before reaching its destination. In Florida's humid climate, this issue is particularly common. A professional contractor can inspect and seal any leaks in your ductwork, ensuring that the cooled air reaches every room in your home. Insufficient AC Size When your AC unit is undersized for your home, it is likely to consistently face challenges in achieving your desired temperature. Air conditioning systems are classified by tonnage (1 ton, 2 tons, 3 tons, etc.). The higher the tonnage, the greater the cooling capacity within a specific timeframe. A skilled HVAC technician will conduct a Manual J calculation to accurately determine the appropriate AC size for your home. However, if the technician took shortcuts, for instance, by only considering square footage when determining the size of your AC, there's a possibility that your AC has been improperly sized.
