How to Repair a Frozen Air Conditioner

Resources

Air filters on HVAC equipment should be changed or cleaned periodically. Replacement air filters come in many sizes and can be purchased at home centers. Reusable filters should be cleaned at least once per season, more regularly in homes with pets. Outdoor units should be cleaned with a vaccum brush attachment and kept clear of bushes and other obstructions. A professional HVAC contractor can help assess if a system may be oversized and need replacement or if the refrigerant is recharged incorrectly.
