A clean air filter is essential for an air conditioner to work efficiently. It allows air to circulate freely throughout the system, ensuring that cold air is able to flow through the evaporator (cooling coil). If the filter becomes clogged with dirt and debris, it will prevent cold air from passing through, resulting in warm temperatures and a decrease in system efficiency. This can lead to more frequent repairs and a shorter lifespan for the unit.
It's important to replace the AC filter regularly to reduce the load on the system. A clean filter will not impede airflow, but a dirty one will restrict it, causing cold air to build up inside the air conditioner and lower the temperature. This can cause ice to form on the coils or evaporator, reducing the HVAC system's ability to remove heat from the air and eventually leading to failure. If your HVAC isn't blowing cold air, check for airflow obstructions like curtains or furniture blocking ventilation grilles.
A dirty or wrongly sized air filter can also be the culprit. As it becomes clogged, system efficiency plummets and the blower must work harder than normal, which can cause internal damage. To prevent this, change the filter every one to three months on average, but check it monthly during times with high pollen counts or excessive dust. In addition, if you notice uneven temperatures or if the temperature doesn't match your thermostat, a clogged air filter may be to blame.
According to the US Department of Energy, a dirty air filter can cause a 15% increase in energy consumption. To avoid this, try cleaning some of the dirt on the filter when your air conditioner doesn't need to be turned on anyway.
