Keep Your Cool: Expert Tips for Essential AC Unit Maintenance

O'Fallon, MO – As summer approaches, ensuring your home's air conditioning unit is in top condition is crucial for comfort and efficiency. A local HVAC professional from Stay Cool Climate Control recently shared valuable insights into maintaining outdoor AC units, emphasizing the importance of regular cleaning. According to the expert, the outdoor unit's primary function is to reject heat, and accumulated dirt, pollen, and debris can significantly impede this process. "One of the most important things you can do every single year is clean your outdoor air conditioning unit," he stated. For homeowners, a simple method involves shutting off the AC at the thermostat and using a garden hose to spray the coils at a 45-degree angle. It's crucial to avoid using a pressure washer or excessive force to prevent bending the delicate fins. "If you notice the fins start bending on the coil, that's a problem. Stop because you're not doing it properly," the professional advised. Professional technicians, however, perform a more in-depth cleaning. After powering off the unit and removing the top and sometimes side panels, they clean the coils from the inside out. This method effectively pushes out all accumulated dust, debris, and dander from the coil's interior. Following the internal cleaning, they rinse the unit from the outside and clean the surrounding pad and siding to ensure all dislodged material is removed. Regular cleaning, whether by a homeowner or a professional, is vital. It helps maintain optimal temperatures, keeps pressures and amp draw down, reduces energy bills, and extends the overall life of the unit. This annual maintenance is essential for most environments to ensure your AC system operates efficiently throughout the hot months.
