5 REASONS YOUR AC IS BLOWING WARM AIR AND HOW TO FIX IT

5 REASONS YOUR AC IS BLOWING WARM AIR AND HOW TO FIX IT

INTRODUCTION

When summer heats up in Coquitlam, BC, the last thing you want is your air conditioner blowing warm air. This common problem can be frustrating, but understanding the reasons behind it can help you find a solution. Here are the top five reasons your AC might be blowing warm air and what you can do about it. Get more info hvac company

HOW AIR CONDITIONERS WORK

To understand why your AC might blow warm air, it helps to know how it works. Air conditioners use a refrigerant to absorb heat from inside your home and transfer it outside. The refrigerant moves through a cycle that includes an indoor evaporator coil and an outdoor condenser coil. The cool air is then circulated back into your home, while the heat is released outdoors. If something disrupts this process, your AC may stop cooling properly.

2.1 CLOGGED AIR FILTER

A dirty air filter is one of the most common reasons for an AC blowing warm air. Filters trap dust, pet hair, and pollen to keep your air clean. Over time, these particles can clog the filter, restricting airflow and reducing your AC’s efficiency.

To fix this, check your filter and replace it if it’s dirty. Regularly changing or cleaning the filter (every 1–3 months) ensures proper airflow and helps your system cool effectively.

2.2 REFRIGERANT LEAK

Refrigerant is essential for cooling, but leaks can occur over time due to tiny cracks in the system. When refrigerant levels drop, your AC loses its cooling power and starts blowing warm air.

Detecting a refrigerant leak requires a professional HVAC technician. They can locate the leak, repair the damage, and refill the refrigerant. Don’t attempt to fix refrigerant issues on your own, as handling it requires specialized training.

2.3 INCORRECT THERMOSTAT SETTINGS

Sometimes, the problem is as simple as the thermostat settings. Ensure the thermostat is set to “Cool” rather than “Heat.” Also, check the fan setting. If it’s set to “On,” the fan will blow air even when the system isn’t cooling, which can feel like warm air. Switch the fan setting to “Auto” so it runs only during the cooling cycle.

2.4 DIRTY CONDENSER UNIT

The outdoor condenser unit plays a critical role in releasing heat. If it’s covered in dirt, leaves, or debris, it can’t function properly, causing your AC to blow warm air.

To fix this, clean the area around the condenser and gently spray the coils with water to remove dirt. If the problem persists, contact an HVAC technician for a deeper inspection.

2.5 LEAKY DUCTS

Air ducts deliver cool air throughout your home. If there are leaks, cool air escapes before reaching your rooms, making your AC seem ineffective.

Signs of leaky ducts include uneven temperatures in different rooms and high energy bills. A professional can seal the ducts and restore proper airflow.

CONCLUSION

If your AC is still blowing warm air after trying these fixes, it’s time to call a professional. Regular maintenance can prevent many of these issues and keep your system running smoothly. For expert AC repair in Coquitlam, BC, contact Air Experts and stay cool all summer long.
