Why Is Your AC Blowing Hot Air??
Your air conditioner is blowing warm air because something is turning off the cooling system while the fan is running. Your air conditioner can be pumping heated air instead of the cool air you’ve been desiring for a number of various reasons.
There are a few common reasons why AC blows hot air:
- Low Refrigerant Levels:
Your air conditioner’s refrigerant levels may be low, which could be a sign of a refrigerant leak. Your air conditioner’s refrigerant pipes are sealed, so if it’s working properly, no refrigerant should leak from it. If you notice frost concentrating on an exterior cable, you might be able to pinpoint where the refrigerant leak in your air conditioner is occurring.
- Return Vents Closed or Blocked:
Here’s another problem with airflow that could make your air conditioner blow warm air. Could vent grilles have been shut throughout the winter and never opened again? Or, are they being blocked by furniture or another object (this happens frequently in offices)?
- Dirty Evaporator Coils:
Condensation will freeze on the dirt when the evaporator coils in your air conditioner are unclean. An AC unit may stop producing cool air if ice forms on filthy evaporator coils.
- Disconnected or Leaky Ducts:
It’s also possible that you have duct-related airflow issues that you can’t see. Return air might not be reaching the unit if a duct has holes, breaks, or is entirely detached. The AC may be spewing warm air because cooled supply air is being wasted in your walls, attic, or crawl area.
- Thermostat Settings are Off:
There can be an issue with your thermostat settings if your air conditioner or thermostat is new or has recently been rewired. Problems with thermostat settings rarely happen unexpectedly and without a known cause.
- Loss of Power to the Outdoor Unit:
An indoor evaporator/air handler unit and an outdoor condensing unit are common components of air conditioning systems. The fan will continue to circulate air in your space if the air handler is operating properly. However, there won’t be any cooling if the condenser unit malfunctioning, which results in your air conditioner blowing heated air.
- Refrigerant Leak:
Refrigerant is the gas that circulates through your air conditioner, and it is what actually causes cooling. Since the system is a closed-loop, you shouldn’t need to add more refrigerant unless there is a leak in the coils or refrigerant line. Your system loses cooling capacity and refrigerant charge when that occurs.
If a minor issue is discovered, it is simple to resolve. Some of these problems will need the help of an experienced HVAC technician to be fixed, but you might be able to handle one or two of these difficulties yourself.
