Often if an AC system is running but not cooling a clogged or blocked condenser coil can be to blame. If your air conditioner has stopped cooling your home we recommend calling a licensed HVAC professional from Dunn’s Heating, Cooling, Plumbing, and Electrical to diagnose your AC issue. Trying to diagnose or repair your air conditioner on your own can not only turn a small problem into a large one, it can also be dangerous.
