AC BLOWING HOT AIR –  Let’s investigate the cause

The operation of an air conditioner is to cool the air in a room adequately. However, sometimes even when the thermostat is set correctly, it blows warm air, and regardless of how long the air conditioner is running, the rooms remain stuffy and damp.

An AC blowing hot air indicates that something is wrong with your unit’s cooling system. You may hire an air conditioning specialist to check and repair the issue. However, there are some things you can check to save time, energy, and money.

It also goes for any form of difficulty or damage in residence, such as water heater leaking, tap leakage, etc. Before contacting support, you may do some troubleshooting to decide if the issue can be resolved or you need to hire professional assistance. 

Speaking of AC, what may be incorrect and how to correct it is as follows:

You may experiment with simple problems and fixes

  1. Clogged or too restrictive filter

While a clogged air filter may not directly cause heated air to blow, it will add to the issue and diminish your air conditioner’s capacity to produce cold air over time. Certain filters may also be problematic because, although they are intended to keep tiny impurities out of your house, they can also obstruct airflow. Replace or clean the air filter regularly – every 1-3 months, depending on how quickly they accumulate dirt.

  1. Clogged Evaporator or condensing coil 

Dirt and debris may obstruct the functioning of your air conditioner, resulting in the AC blowing warm air. Cleaning the unit thoroughly and leaving at least a foot of free space around it is critical. Maintain a trim around vegetation and overhanging trees to prevent leaves from entering the unit.

  1. Tripped Breaker 

Without electricity, the outside unit will be unable to cool or chill the air moving through your house. If the breaker is the source of the issue, it’s very easy to determine. Verify that the circuit breaker or fuse panel is providing power to the item.

If the circuit breaker or fuse has been tripped or blown, you should contact a professional immediately.

  1. Disabled Thermostat Settings

Your thermostat’s settings may have been altered accidentally, or you may have forgotten to shift from “warm” to “cool.” Ascertain that the thermostat is set to the proper temperature and auto mode, not on. When the air conditioner is set to “on,” it keeps circulating air even when it’s not cooling.

Here are a few other reasons why your air conditioner may be blowing hot air.

  1. Refrigerant Leak

The refrigerant is the substance that circulates throughout the system to cool the air. If coolant levels fall due to a leak, the air conditioner will lose its cooling power and only blow warm air. If this occurs, contact a technician to check for a refrigerant leak. It will need to be shut down and refill the coolant.

  1. Outdoor device loses power

Certain systems utilize an indoor air handler in conjunction with an outdoor condenser. If the indoor unit is functioning properly, the fan will circulate air throughout your home, but without the condenser unit cooling it, the air will remain warm.

  1. Leaking Ducts

Airflow issues may also occur as a result of faulty ducts. If tiny leaks occur in the ductwork of your HVAC system, all conditioned air is lost to the environment, and no cool air reaches the room’s air vents.

As a result, you will either get warm air or none at all. It’s a significant energy waste and will increase your utility bills as the AC attempts to compensate for the loss. If your ducts are easily accessible, you can inspect them yourself, but it’s best to leave the inspection, cleaning, and repair to a technician.
