AC Not Cooling? 6 Fast Fixes for SW Michigan

1. Low refrigerant from a leak. A closed system should not lose refrigerant; if it is low, there is a leak that needs professional repair.
   
   
2. Frozen evaporator coil. Restricted airflow or low refrigerant can ice over the coil, blocking cooling entirely.
   
   
3. Dirty condenser coil. A grimy outdoor coil cannot release heat, so the system runs without cooling.
   
   
4. Failing compressor. The compressor is the heart of the system; when it weakens, cooling fades.
   
   
5. Leaky or disconnected ducts. Cool air escaping into the attic or crawlspace never reaches your rooms.
   
   
6. An undersized or aging system. A unit that is too small or near the end of its life simply cannot keep up in peak heat.
   
   

Several of these overlap, which is why guessing rarely works. Our AC repair technicians test the whole system to find the real cause instead of swapping parts at random.
