How To Repair TRANE Air Conditioner That Does Not Blow Cold Air

This information enables better preparation for repairing your unit quickly. Still, we have to mention that not every issue homeowners can resolve themselves. The most common cause of air conditioners not blowing cold air is a lack of adequate air flow. In a properly working air conditioner, a fan will draw air over the evaporator coils, where it is cooled, and then be re-circulated back into the room. If the air filter is dirty or clogged, there may be little or no air flow over the evaporator coils, which may cause them to become too cold and frost or ice can form on them, restricting the airflow even more. This will result in little or no cool air being circulated into the room. The air filter is normally located behind the front grille which may have a side access opening. Clean or replace the filter as often as required. If the evaporator coils are very dirty then cleaning with soapy water and a soft brush will be required and we also recommend changing the filter. It goes without saying you don’t need to do everything personally - address any problems as soon as possible to our professional helpers. Why? Because a broken air conditioning unit is often difficult and inconvenient to repair. Don’t hesitate to ask for help!
