Why is my AC running constantly but my home still feels sticky or humid?
When your AC runs nonstop but fails to dehumidify your home, it's a sign of an underlying issue. This often points to a system that is too large for your space, causing it to cool too quickly without effectively removing moisture. Other causes include low refrigerant levels or issues with your thermostat. Our professional air conditioning services team can diagnose the problem and provide a solution that improves both temperature and humidity.

How often should I have my AC system professionally serviced?
Regular professional maintenance is key to the longevity and efficiency of your air conditioning system. We recommend having your AC unit serviced at least once a year, preferably in the spring before the heat sets in. This proactive approach helps identify minor issues before they become major problems and ensures your system is ready to deliver peak performance all season long.

Why is there mold or mildew growing around my AC vents?
Mold or mildew growth around your AC vents or in your ductwork is often a sign of excess moisture in your system. This can be caused by issues like a clogged condensate drain line or an improperly sized unit. Beyond being unsightly, this can negatively impact your indoor air quality. For a thorough inspection and solution, trust our professional air conditioning services team.

How often should I change my air filter?
Changing your air filter regularly is one of the easiest ways to maintain your AC system's efficiency and improve air quality. For most homes, we recommend replacing the filter at least every three months. Some filters may last up to six or 12 months, depending on the filter type and the size of your home. A dirty filter restricts airflow, forcing your unit to work harder and increasing energy costs.
