SAEDNEWS: Air conditioners are essential for maintaining indoor comfort during hot weather, but sometimes they may blow warm air instead of cooling the environment. This article explores seven common reasons why a window or split-type air conditioner might emit hot air
According to SAEDNEWS, Few things are more frustrating on a hot summer day than turning on your AC and getting blasted with warm air instead of that much-needed cool breeze. If your window or split air conditioner is blowing hot air, don't panic — there are several common reasons this might be happening.
Here are the 7 most likely causes — and how to fix them:
If your AC has both cooling and heating functions, a wrong setting on the remote control might be to blame. Check to make sure it's set to "Cool" and not "Heat." A single button press can change the mode, especially with multifunction remotes.
Clogged filters can block airflow and cause ice buildup on the cooling coils. This restricts the cooling process, often resulting in warm air coming out. Cleaning or replacing the filters regularly helps maintain cooling efficiency.
Skipping annual servicing can lead to dust buildup, electrical issues, and more. Yearly maintenance not only keeps your AC working efficiently but can also prevent expensive damage like a burned-out compressor.
The refrigerant (cooling gas) is essential for cooling. If levels drop due to leaks or long-term use, the AC will struggle to cool air and may blow warm instead. In such cases, a refill by a professional technician is necessary.
The fan motor helps circulate air. If it fails, airflow is disrupted, resulting in warm air output. Replacing a damaged motor should be left to a qualified HVAC technician.
The compressor is the heart of your AC. If it’s damaged, overheating, or receiving low voltage, the cooling function can break down entirely. Causes include physical damage, dirty coils, and poor installation (e.g., direct sunlight exposure).
A malfunctioning thermostat might send incorrect signals, causing your AC to behave erratically and blow hot air instead of cool. Replacing or recalibrating the thermostat may resolve the issue.
If your air conditioner is blowing hot air, it's not always a major issue — but ignoring it could lead to costly repairs. Check these common culprits, and if you're unsure, contact a certified AC technician. Stay cool and enjoy the summer! ❄️☀️
