Before diving into solutions, it’s crucial to understand the underlying reasons why your AC unit might freeze. The freezing occurs when the refrigerant, which absorbs heat from your home, gets too cold and forms ice on the evaporator coil. This coil is located inside the indoor unit (usually in your attic, closet, or basement). Here are the primary culprits: Emergency Heating Repair Near Me Air Conditioning Repair Contractor Air Conditioning Service Companies Near Me
