In the summertime, your home will likely feel like a sauna. Cars and indoor spaces can become equally oppressive with warm air, which is what you’ll experience with an air conditioner that’s blowing out warm air. If you live in a house with air conditioning, this shouldn’t be much of a concern. However, if you happen to have an older AC unit then it might end up being problematic for you. When your AC unit is blowing out warm air, it means that it isn’t able to cool the surrounding area effectively enough. This is because the internal thermostats aren’t functioning as they should because they are not getting cool enough air from outside the house.
The air flowing out of your aircon must feel refreshing and cool. When it feels hot or lukewarm, you know there is a problem. While you might have to contact an aircon technician, the good news is that you can sometimes troubleshoot this problem and fix it yourself.
The problem could originate in one or more of these places:
Outside Air Quality
The outside air quality inside your home can affect how efficiently your AC unit works. If it’s dusty or smoggy outside, then it could throw off your unit’s calculations. It could also be a result of standing water, which is something that you might not be aware of. If you have a sump pump, you should be able to tell if it’s not draining properly. If so, then you can have the sump pump replaced. If not, then your air quality could be a factor.
Outdoor Air Venting
If your air conditioning unit is blowing out warm air because it isn’t getting enough outside air, then it might be because the venting for that air is not working properly. There are two scenarios here: either your outdoor air vent is blocked or it isn’t in the correct position. Blocked outdoor air vents are the most common reason for a unit blowing out warm air. You can unblock it by using a broom to sweep any dust out of the vent and then inspect the venting with a flashlight.
Inadequate or Old AC Unit
A possible cause of your unit blowing out warm air could be an inadequate or old air conditioner. If it’s the AC unit that’s the problem, then you’ll want to consider having it replaced. If you have an inadequate AC unit, then it will be able to cool your home adequately. However, it will also be using a lot of power, which can result in your electricity bill rising substantially. An AC unit can also be old if it has been installed for a long time. If so, then you’ll want to replace it.
Improperly Configured ductwork
There are a few things that you will want to make sure are in place if you have an AC unit blowing out warm air. First, you’ll want to make sure that your ductwork is properly installed. This could mean having it redone by a professional. It could also mean having the ductwork cleaned by a professional.
Not Enough Fans Installed
If you have an older AC unit that’s blowing out warm air, then you might want to install more fans to help it out. This will mean that it will use more power, but it should be able to keep things cooler in the process. You could also consider upgrading your AC unit to one that’s more powerful and more energy-efficient at the same time.
Make Sure There’s Proper Ventilation in the House
When you have an AC unit blowing out warm air, then you’ll want to make sure that there’s adequate ventilation in your home. This could mean opening up windows, using fans, and opening up doors and closets.
Summary
A warm air conditioner that’s not able to cool the air effectively enough because it isn’t getting enough cooling air from outside is blowing out warm air. There are a few possible reasons for this. First, it could be a result of outside air quality inside your home being poor or it could be that the AC unit itself isn’t able to cool the air effectively enough. This could mean that the AC unit is too old, insufficiently installed, or improperly configured. If so, then you’ll want to make sure that the ductwork is properly installed, that the AC unit is able to cool the air effectively enough and that there’s adequate ventilation in your house. Keep in mind though that an older AC unit could work just fine and still be problematic if it blows out warm air. In this case, you’ll want to replace it with a more powerful and energy-efficient one to ensure that it does its job properly.
