Why Is My Central Air Conditioner Not Blowing Cold Air. When the blades are covered with an excessive amount of dust or the blower motor is broken, you will have issues with your system. If the air blowing from the vent is not cold, the compressor may be malfunctioning or misaligned.
If you have noticed your ac blowing both cool and lukewarm air off and on, it may be because your thermostat is set to “on”. But on some occasions, this coil can freeze, which can result in your central ac not blowing cold air. If the capacitor blows during a power outage, the compressor will not come back on once power is restored.
There are a wide range of reasons why a central air conditioner won’t blow cold air, many of which might be an easy fix.
Malfunctioning thermostats, dirty filters or compressors, and low refrigerant levels are just a few of the culprits for a central ac not blowing cold air. When central ac is not blowing cold air, for example, you want to shut it off to prevent further damage to a $3000+ unit. On the indoor portion of your ac unit, you’ll find an evaporator coil. Located inside the air handler, this fan is responsible for pushing the cold air through the ducts.
