Why Is Warm Air Coming Out of My A/C? – Dial One Sonshine - Orange County HVAC

The only thing worse than an A/C that’s not blowing out air is an A/C that’s blowing out warm air!

The air coming out of the vents should of course always be refreshingly cool, so if you’re wondering why warm air is coming out, that’s a very good question. There are a lot of possible culprits, and we’re going to go over all the possibilities so you’ll know what to do if this happens to you in your Orange County home.

1. Is it actually set to cool?

We don’t want to insult you with this suggestion or anything like that, but sometimes the simplest answer is the right one! Be sure that the thermostat is set to “cool” and that the fan is on auto. Maybe someone else in the family accidentally ran into it, or tampered with it, and so it’s actually not a problem with your cooling system at all, but with the temperature setting.

2. Have you changed your air filter recently?

If you don’t change your filter, then your A/C unit is working harder than normal to push air through the filter and over the coils (it’s actually warm air that is blown over the coils, which cools that air down). If you don’t change your air filter and it’s clogged, then it’s no wonder you’re having an issue with air flow and getting cool air. Your system can’t function properly with a clogged filter!

3. Do you have a leaky duct problem?

If your A/C is blowing warm air out, then it’s possible the problem is leaky ducts. Air is escaping from somewhere – through cracks or holes in the ducts. This causes cool air to escape into your walls or your attic, and all that’s left coming through the vent is unhelpful hot air!

4. Do you have an issue you need a tech’s help with?

It’s also very possible that warm air coming out of your vents indicates a larger problem with your A/C system. For example, dirty condenser coils make it difficult for your system to release heat from indoors into the outdoors. Or, the problem could be a refrigerant leak, which makes it tougher for the refrigerant to do its job of absorbing your home’s excess heat and can also cause the refrigerant line to freeze, so this is an issue to take care of quickly!
