Having a clean air conditioner (AC) coil is essential for efficient operation. When the coils are covered in dirt, it makes it difficult for the equipment to transfer heat, resulting in longer run times and increased energy consumption. Not only that, but dirty coils can corrode and lead to coolant leaks. The condenser coils of an AC system are located outside and are prone to dirt buildup over time.
If you don't take steps to keep them clean, your residential air conditioner may experience some serious issues. If the filter hasn't been changed in a while and the air conditioner isn't blowing cold air like it used to, it could mean that the system has frozen. Clogged filters restrict the flow of cold air, which can cause it to build up inside the AC unit and result in ice formation on the coils. When your air conditioner's air filter is full of dust or clogged, energy consumption can increase by up to 15%.
If you don't routinely clean or change the filter, the unit will need more energy to release and circulate cool air throughout the room. To ensure your AC system is running efficiently and effectively, it's important to keep the coils clean. A buildup of 26% dirt on the coils can cause your AC unit to work harder and consume more energy, leading to parts wearing out and breaking down. Regularly cleaning or changing your air filter is essential for keeping your AC system running smoothly.
It's also important to check for any signs of corrosion on the coils and take steps to prevent further damage.
