Why Is My AC Blowing Out Warm Air?


ac blowing hot airDuring the scorching summer months, a malfunctioning air conditioning system can make the time frustrating and sweaty. If you find your AC blowing warm air instead of the blast of cold you were hoping for, there could be several underlying reasons. Many of these issues can be easily fixed at home, while others require the expertise and experience of a professional. Let’s look at some reasons it might be happening, and whether it’s something you can handle or if you need to call the professionals for HVAC services. 

Check Your Thermostat Settings 

One of the most straightforward explanations is just an incorrect thermostat setting. Check the temperature to ensure that your thermostat is set to cooling mode and that it is set lower than the ambient temperature. Additionally, check if the fan setting is on “auto” rather than “on” to prevent the fan from constantly running and circulating warm air. The fan can be helpful, but it does put some extra wear and tear on your system.

Dirty or Clogged Air Filters 

Dirty or clogged air filters can restrict airflow and cooling performance. When filters become clogged with dirt, dust, or debris, they obstruct the airflow and reduce the efficiency of your AC system. Regularly inspect and clean or replace your air filters to maintain optimal airflow and ensure cool air is being circulated throughout your space. If you’re unsure what filters you need, Raynor’s AC services can help you get the best filters for your home and system.

Refrigerant Issues 

Refrigerant is a crucial component in the cooling process. If your system has a leak or is low on refrigerant, it can result in warm air blowing from the vents. Professional HVAC services from Raynor can identify and repair any refrigerant leaks, recharge the system, and ensure the correct levels are maintained to restore your system’s cooling capacity. 

Faulty Compressor 

The compressor is responsible for circulating refrigerant and facilitating the cooling process. A malfunctioning or faulty compressor can hinder the cooling cycle, resulting in warm air being discharged instead of cool air. If you suspect an issue with the compressor, you should seek assistance from a qualified HVAC technician who can diagnose and fix the faulty component.

Damaged Ductwork 

Leaky or damaged ductwork can result in cooled air escaping before it reaches the intended areas. Inspect your ductwork for any visible signs of damage, such as disconnected joints, holes, or gaps. If you find any damage, you’ll need to arrange for professional AC services for repair. An experienced technician can seal or repair the ducts to restore proper airflow and ensure that cooled air is effectively moved around your space.

Electrical or Component Issues 

Electrical problems or faulty components within the AC system, such as malfunctioning motors, sensors, or relays, can disrupt the cooling process and result in warm air blowing from the vents. Raynor’s professional HVAC technicians possess the expertise to diagnose and address electrical or component-related issues, ensuring that your AC system operates efficiently and delivers cool air as intended.

When your AC starts blowing warm air, it’s important to identify and resolve the underlying issue as soon as possible. Whether it is a quick fix like the thermostat setting or something more complex such as a refrigerant leak, professional HVAC assistance from Raynor Services can help.
