Have you noticed that your home’s air conditioning system doesn’t feel as if it is cooling properly, or maybe even blowing warm air? This is one of the most commonly asked questions among Orange County residents when they are having home cooling issues.

If you’re wondering what could be the cause of this annoying disturbance in your home comfort, then we can help. Read on to learn the causes and solutions to this fairly common problem. We’ll help you troubleshoot this annoying problem.

First, decide what type of problem you’re actually experiencing with your A/C:

Air Is Blowing Out of the Vents, But It Is Warm Air

This is a very common issue that people notice. Here are some great steps to follow if your A/C is functioning, but the air is not coming out cold.

Examine Your Air Filter

Have you been checking and changing or cleaning your air filter regularly? If not, then you could have a very dirty air filter. A dirty filter can block the airflow to your system’s air handler, causing the air that is coming out of your home’s vents to blow out warmer and weaker. If it’s been a long time since you’ve changed your air filter, then do so immediately and see if that alleviates your issue. If it’s been a really long time since you’ve changed your filter, change it. Then, call in an HVAC tech to check out your system for any potential damage not changing the filter could have caused.

Check Your Thermostat

This may seem silly to have to mention, but occasionally the cause of your A/C blowing warm air is that sometimes the fan is set to “auto” or “fan”, which causes your system to continuously circulate air throughout your home, even if the cooling unit isn’t running. This can happen for a variety of reasons, oftentimes it is just accidentally switched on. Check this out to make sure it’s not just an incorrect setting on your thermostat causing warm air to come out of your vents.

Examine Your Outdoor Unit

If you’ve been paying decent attention to your home’s indoor A/C unit, but don’t really pay much mind to your outdoor unit, then do so now. If the unit is covered in weeds, leaves, grass or other debris, it can inhibit how effectively it will cool your home. Clear any debris from your outdoor unit and keep it free from outdoor buildup.

It Could Be a Refrigerant Leak

If none of the above solutions fix your A/C, then it could be a refrigerant leak. Unlike gas in your car, your A/C doesn’t “use up” refrigerant. So, if your air conditioner is low on refrigerant liquid, that means that there is a leak in your unit, and you will need to call in a professional HVAC technician to fix this problem.

If Your A/C Isn’t Blowing ANY Air

If your air conditioner simply isn’t blowing any air at all, then it’s a good time to call in a professional to help assess the problem. It could be electrical or a failure in the system itself. Oftentimes an A/C will shut down to prevent bigger problems, such as overheating or water damage to your home.
