First, check your air filter; a clogged filter is a common culprit for reduced airflow and cooling. Also, ensure your outdoor unit isn't blocked by leaves or debris, which is frequent in our area. If these are clear, the issue could be low refrigerant, a failing compressor, or a dirty evaporator coil. For a proper diagnosis and repair to beat the Dundalk heat, it's best to call a professional technician.

Regular professional maintenance is key. It includes cleaning coils, checking refrigerant levels, inspecting electrical components, and lubricating moving parts.

For Dundalk homeowners, it's the best way to ensure reliability, improve efficiency, and extend your system's lifespan.
