Help! My AC is Blowing Warm Air! What Should I Do?

There are few things more frustrating than a malfunctioning AC unit, especially when the warm weather sets in. If your once-reliable air conditioner has started blowing warm or room-temperature air, it’s definitely time to take action. Fortunately, there are some simple checks you can perform before calling in the professionals at Essential Home Performance.

Troubleshooting 101: Before You Call the HVAC Experts

• Thermostat Check: Start with the basics!
  • Is your thermostat set to “cool” and the temperature set below the current room temperature?
  • Is the fan set to “auto” and not “on”? The “on” setting means it will blow continuously, regardless of air temperature.
• Clean Air Filter: A dirty air filter severely restricts airflow, causing numerous issues including warm air from the vents. Your filter should be changed regularly.
  • Check your filter and replace it if dirty or clogged.
• Outdoor Unit Check: Your outdoor condenser unit needs space to breathe.
  • Ensure there are no weeds, debris, or objects blocking the airflow around your condenser unit.
  • Check if the unit is running. If not, try resetting the breaker associated with your AC.

If the Simple Checks Don’t Help…

If the problem persists after these basic steps, it’s time to call the experts at Essential Home Performance. Attempting to fix a complex AC issue yourself can cost you more in the long run. Here’s what could be causing your warm air problem:

• Refrigerant Leak: Your AC relies on refrigerant to cool the air. A leak will compromise the cooling cycle and result in warm air output. Refrigerant must be handled by a licensed HVAC technician.
• Compressor Issues: The compressor is the heart of your AC unit. A malfunctioning compressor can lead to a range of problems, including reduced cooling ability.
• Electrical Problems: Loose wiring, damaged capacitors, or other electrical failures can disrupt your AC’s operation.
• Frozen Coils: Frozen evaporator coils within your indoor unit can prevent the AC from cooling your home. This can be caused by low refrigerant, airflow problems, or other issues.

Why You Need a Professional Diagnosis

While a few obvious problems might cause your AC to blow warm air, several more serious issues can be the culprit. HVAC technicians have the equipment and specialized knowledge to:

• Accurately diagnose the problem: Our trained technicians understand the complexities of AC systems for precise troubleshooting.
• Safely and effectively repair your unit: Whether it’s refrigerant recharging, replacing a faulty compressor, or fixing an electrical malfunction, we get the job done right.
• Prevent further damage: DIY attempts without proper tools or knowledge can worsen the problem, potentially resulting in more expensive repairs.
