Why is My AC Blowing Hot Air? How to Fix?

It’s a hot summer day in North Georgia, and you’re looking forward to the cool comfort of your home, only to find your AC blowing hot air. This common issue can be a source of significant discomfort, especially during the warm seasons prevalent in this region. Understanding the potential causes and solutions is essential in addressing this problem effectively. In this article, we’ll explore the reasons behind an AC unit blowing hot air and how Climatrol Air, a trusted Carrier HVAC product dealer, can help resolve these issues.

1. Thermostat Settings

Sometimes the simplest explanation is the correct one. Incorrect thermostat settings can cause your AC to blow hot air. Ensure that the thermostat is set to ‘cool’ and not ‘heat’ and that the temperature is set lower than the current room temperature. In North Georgia, where temperatures can fluctuate, it’s important to regularly check your thermostat settings to ensure they align with your cooling needs.

2. Clogged Air Filters and Dirty Evaporator Coil

A clogged air filter restricts airflow, reducing the AC unit’s efficiency and potentially causing it to blow hot air. In the dusty, pollen-rich environment of North Georgia, air filters can become clogged more frequently, necessitating regular checks and replacements. Similarly, a dirty evaporator coil can impede the cooling process, leading to the same issue. Carrier HVAC systems, known for their durability, also require routine maintenance to prevent these problems.

3. Compressor Malfunction

The compressor is the heart of your AC unit, responsible for circulating refrigerant and facilitating the cooling process. A malfunctioning compressor can lead to your AC blowing hot air. This issue can be more complex and often requires professional intervention. Climatrol Air’s team of certified technicians is adept at diagnosing and fixing such issues, ensuring your Carrier system operates optimally.

4. Outdoor AC Unit Blocked

The outdoor unit of your AC needs adequate airflow to function correctly. If it’s blocked by debris, plants, or dirt, it can overheat, causing the AC to blow hot air. Regularly clearing the area around your outdoor unit is a simple yet effective step in maintaining your AC’s efficiency.

5. Refrigerant Leak

Refrigerant is essential for the cooling process, and a leak can significantly reduce your AC’s ability to cool the air. Signs of a refrigerant leak include hissing noises, ice on the refrigerant lines, and, of course, the AC blowing hot air. Refrigerant issues are particularly sensitive and require professional handling due to environmental and safety regulations.

6. Electrical Issue

Electrical issues, such as a tripped circuit breaker or a blown fuse, can affect your AC’s performance. Regular electrical maintenance and timely repairs are crucial, especially given the frequent storms and power fluctuations in North Georgia, which can impact the electrical systems of HVAC units.
