When you turn on your air conditioner, you expect to be cooled down in a manner of moments, which is what makes it so frustrating when only hot air comes out of your AC system. If you notice that your air conditioning unit is blowing only hot air, there are a few possible causes that you should examine to fix the problem.

By getting a few tips and a little professional guidance, you should be able to diagnose why hot air is blowing from your air conditioner. Read about some of the potential causes of your AC hot air problem and find out how you can get your system back up and running.

Check Your Liquid Levels

One of the most important factors that allows your air conditioner to blow cold air instead of hot is its Freon or refrigerant. If you notice hot air blowing from the AC unit, then one of the first things you should check is the level of Freon in your system. When your refrigerant level gets low, it makes it increasingly harder for your system to cold air, and often leads to AC air coming out hot. When your Freon runs out completely, there is no way for your AC unit to create cold air.

Fortunately, low or non-existent refrigerant levels are easy to correct, and topping off your refrigerant should return your system to full functionality. However, if you’re unsure where to check your Freon or how to refill it, you might need to schedule professional HVAC service.

Clean or Replace Your Air Filters

For your air conditioning system to function at its fullest capacity, air must be able to flow freely throughout your system, which requires clean air filters. While almost everyone knows that clogged air filters are a problem for air flow, they can also be an issue when it comes to hot air coming from your AC system.

When air cannot easily flow through your air filters, it causes the air to stagnate. This, in turn, causes the air to heat up, which can lead to hot air blowing from your air conditioner. Make sure that your cold air can flow unimpeded by periodically checking your filters. Clean them regularly and occasionally replace them, and you’ll be able to keep the cold air flowing.

Inspect Your Condenser Unit

The condenser unit is the most important piece of equipment that your air conditioner possesses, as it is responsible for your AC’s ability to alter the temperature of refrigerant and control the temperature in your home. When your condenser unit isn’t working correctly, it can cause your system to blow hot air instead of cold.

While some condenser problems may require repairing an HVAC unit, others are more simple to address. For example, if it gets dirty, a condenser will not function at its optimal level. If hot air comes from your system, check the condenser and clean it if it has accumulated a large amount of dirt or dust.
