AC Unit Starts Blowing Warm Air

Were you experiencing Warm Air from Your AC Unit During a Scorching Summer? 

Don’t Panic Just Yet – The last thing anyone wants during an unbearably hot summer is their air conditioning system to fail them. It’s particularly distressing when your trusted AC unit starts blowing warm air instead of the cool breeze you desperately need.

Understandably, thoughts of expensive repairs might flood your mind, especially knowing that the demand for AC repairs tends to skyrocket during the summer, often driving up the rates.

However, there’s no need to lose hope immediately. The issue might be minor and doesn’t require a costly professional fix. There could be various factors causing your AC unit to function below its best, and many of these issues can be addressed through simple troubleshooting methods. 

Before you call a technician, here are some DIY tricks to restore your AC unit’s performance.

Check the Thermostat

It Might Sound Simple, But Check Your Thermostat First. As basic as it may sound, you’d be surprised how often the culprit behind a malfunctioning air conditioner is an incorrectly set thermostat. It’s easy for thermostats to get bumped or accidentally adjusted, especially in busy households or during cleaning. If your AC unit is blowing warm air, check your thermostat settings first.

Ensure the system is set to “cool” rather than “heat.” You might have unintentionally flipped the switch while attempting to adjust the temperature, which is a more common mistake than you think. Additionally, please take a moment to look at the temperature setting itself. On scorching days, you might find that the set temperature is higher than you’d prefer, causing the AC to blow out warm air compared to your comfort level.

Ensuring your thermostat is correctly set can save you a lot of stress.

Do Some Cleaning

Understanding the Fundamentals: Airflow and Clean Components are Key Air conditioning units that operate on a relatively straightforward principle: they pull in ambient air, cool it down through an electrical process, and then circulate the chilled air back into your home.

However, various factors can impede this cycle, causing the unit to blow warm air—or sometimes, no air.

  1. The Importance of a Clean Air Filter: If your air filter is clogged, it restricts your AC unit’s airflow to function properly. Inadequate airflow can result in the unit blowing warm air or failing to produce any air circulation. Do you recall the last time you replaced or cleaned your air filter? If you can’t remember, it’s probably overdue. Changing a dirty air filter is a simple, cost-effective way to enhance your AC unit’s performance and efficiency.
  2. Keep an Eye on the Condenser Unit: Located outside, the condenser unit is another crucial component that outdoor elements can easily obstruct. Check its surroundings for blockages like dirt, tall grass, leaves, or overgrown bushes. Make sure the unit can “breathe” freely, and while you’re at it, inspect any moving parts to ensure they’re functioning correctly. Removing any obstacles and maintaining clear airflow can significantly improve your AC’s cooling ability.
  3. Please don’t Neglect the Cooling Coils: Air conditioners use evaporator and condenser coils to absorb and release heat, making them key players in the cooling process. When these coils get dirty, they can’t effectively exchange heat, leading to less efficient cooling or warm air being blown into your home. Regular inspection and cleaning of these coils are crucial for maintaining optimal performance.

By giving attention to these components, you not only increase the likelihood of discovering the issue affecting your AC unit, but you also stand a good chance of solving the problem without needing expensive professional repairs.

Call a Professional

When DIY Fixes Don’t Work, It’s Time to Call the Experts.

If you’ve carefully gone through the recommended troubleshooting measures and your AC unit continues to emit warm air. It’s probably an indication that you’re facing a more complex issue. This could mean anything from a refrigerant leak to a damaged duct that requires immediate professional attention.

One savvy approach to avoid last-minute repair costs is to be proactive about your AC maintenance. Consider scheduling diagnostic tests and consultations during the off-season—spring is usually ideal. Many air conditioning repair services offer special promotions, discounts, or package deals during this slower period. Leveraging these opportunities not only allows you to get a comprehensive inspection at a reduced cost, but it can also preemptively identify potential issues before they escalate into costly repairs during peak season.

By having a professional inspection done in the spring, you’re investing in the longevity of your AC unit and ensuring its readiness for the hot summer months. You’ll have the peace of mind that comes with knowing your cooling system is in optimal condition, and you’ll likely save money in the long run by catching small problems before they become expensive emergencies.
