Why is my air conditioner only blowing out room temperature air?

by | Jun 29, 2023

Are you experiencing an issue where your air conditioning system is blowing out room temperature air during heating or cooling cycle? Don’t worry, you’re not alone in this predicament. In this blog post, we will explore the possible reasons behind this issue and explain why it’s crucial to seek expert assistance rather than attempting repairs yourself. Whether it’s a refrigerant issue, dirty indoor filters, or an electrical problem, we’ve got you covered with informative explanations.

1. Refrigerant Issue:

One major reason for your air conditioning system blowing out cool air during the heating cycle is a refrigerant problem. Refrigerant is the lifeblood of your AC system, facilitating the heat exchange process. If there’s a leak or insufficient levels of refrigerant, your system may struggle to generate enough heat. Consequently, it may appear to blow out cool air instead.

To accurately diagnose and resolve refrigerant issues, it’s important to contact an HVAC expert. They possess the necessary tools and knowledge to detect leaks, repair them, and replenish the refrigerant at the appropriate levels.

2. Dirty Indoor Filters:

Another common culprit for cool air during the heating cycle is dirty indoor filters. Air conditioning systems utilize filters to trap dust, allergens, and debris, ensuring your indoor air quality remains clean and healthy. However, if these filters become clogged and dirty, they can impede proper airflow.

Restricted airflow can disrupt the heating process, causing your air conditioning system to blow out cool air rather than warm air. Regular maintenance and cleaning of filters are essential to prevent this issue. Contact a professional HVAC technician to clean or replace your filters, ensuring optimal performance and energy efficiency.

3. Electrical Issues:

Electrical problems within your air conditioning system can also lead to the circulation of cool air during the heating cycle. Faulty wiring, malfunctioning thermostats, or issues with the control board may disrupt the heating function, resulting in cool air being blown into your space.

Since electrical repairs can be dangerous and complex, it’s crucial to hire a certified technician familiar with air conditioning systems. They will inspect the electrical components, diagnose the problem accurately, and provide the appropriate repairs or replacements to restore your system’s functionality.


Experiencing room temperature air blowing out of your air conditioning system during the heating or cooling cycle can be frustrating, but it’s important to remember that finding the root cause requires professional HVAC expertise.
Whether it’s a refrigerant issue, dirty filters, or electrical malfunctions, contacting an expert is the wisest and safest solution.
