HVAC Repair Maryville MO | Call Al's Heating Cooling & Refrigeration

If your AC is running but not cooling properly, it could indeed be a refrigerant leak. First, check your air filter—a clogged filter can mimic cooling issues. If the filter is clean, turn the system off to prevent further damage and call us. Our technicians use specialized tools to locate and repair leaks, then recharge the system with the correct refrigerant to restore efficient cooling and prevent future problems.

In Maryville, with our varying seasons and potential for dust, we generally recommend checking your air filter every month and replacing it every 1-3 months. A clogged filter restricts airflow, forcing your system to work harder, which increases energy bills and can lead to overheating or freezing. Regular filter changes are the simplest way to improve air quality, protect your HVAC equipment, and maintain consistent comfort.

Absolutely. While refrigerant is specific to cooling, a clogged air filter affects both heating and cooling systems. In winter, a dirty filter restricts airflow over the heat exchanger, which can cause the system to overheat and shut down as a safety precaution. For heat pumps, which provide both heating and cooling, a refrigerant leak will impact their heating performance as well. Regular maintenance from our team checks for these issues in both seasons.
