I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I received a call from a customer who reported that their air conditioner was running good but they could not find a leak. I arrived at the customer's home and performed a thorough inspection of the air conditioner. I checked the refrigerant levels, inspected the condenser coils, and checked the evaporator coils for any signs of leaks. After completing the inspection, I found that the air conditioner was not leaking. The customer was happy with the results and thanked me for my help.
