Why Your AC Isn’t Blowing Cold Air

If your AC isn’t blowing cold air yet it is operational, keep reading this post to find out the cause.

Is your AC on full blast but not blowing any cold air? Don’t worry, you’re not alone. In fact, it’s a pretty common problem. But don’t fret, there are a few things you can do to fix it.

Reasons your AC isn’t blowing cold air

If your air conditioner isn’t blowing cold air, there could be a number of reasons why. The first step is to check your air filter and replace it if it’s dirty.

A dirty air filter can restrict airflow and cause your AC to work harder than it needs to. If that doesn’t fix the problem, there are a few other potential causes:

Your thermostat is set too high: Check the temperature setting on your thermostat and lower it to the ideal range of 78 degrees.

The air conditioner is too big for the space: An AC that’s too big for the space will cycle on and off too frequently and won’t properly remove humidity from the air. This can make the space feel colder than it actually is.

The AC coils are frozen: Frozen coils can restrict airflow. Check to see if the coils are covered in ice and, if they are, turn off the unit and call a professional for assistance.

There’s a refrigerant leak: A refrigerant leak needs to be addressed by a trained professional as it can be dangerous. If you suspect there may be a leak, turn off your AC unit immediately and call for help.

How to troubleshoot your AC

There are a few things that could be going wrong if your AC isn’t blowing cold air. The most common problem has to do with the Freon levels in your AC unit.

The Freon level basically means that your appliance is not absorbing heat effectively from your room. Thus, it blows warm air instead of cold air.

If the Freon level is too low, it won’t be able to cool your home effectively. You’ll need to call a professional to come and add more Freon to your unit.

Another possibility is that your evaporator coil is frozen. This can happen if the air filter is dirty and isn’t allowing enough air flow.

The lack of airflow will cause the coils to freeze up. You’ll need to replace the filter and thaw out the coils before your AC will work properly again.

Finally, it’s possible that the outdoor fan isn’t working properly. The outdoor fan helps move heat from inside your home to outdoors.

If it’s not working, then heat will build up inside and won’t be released. This could be another reason why your AC isn’t blowing cold air. You’ll need to call a professional to come and take a look at your outdoor fan motor.

When to call a professional for help

If your AC unit is old, it may need to be replaced. A new unit will be much more energy efficient and will likely last much longer than your old one.

With a new AC, the only problem you might have if your AC isn’t blowing cold air would be the settings.

If your unit is only a few years old, it may just need a tune-up or some repair work. In either case, it’s best to call a professional to diagnose the problem and recommend a course of action.

Tips for improving AC performance

If your central air conditioner isn’t working as well as it should, then try these easy tips to improve AC performance.

1. Check the air filter. A clogged air filter will restrict airflow and make the AC work harder. Clean the filter if it’s dirty or replace it if damaged.

2. Make sure the outdoor unit is clear of debris. Leaves, dirt and other debris can block airflow and cause the AC to overheat.

3. Clean the evaporator coils. Dirty coils can reduce the AC’s efficiency and cause it to overheat. You can clean them yourself with a brush or a special cleaning solution, or you can hire a professional to do it for you.

4. Check the Freon level. If the Freon level is low, it can cause the AC to overheat and shut down. A professional will need to add more Freon to the system.

5. Check for leaks in the ductwork. Leaks in the ductwork can cause cold air to leak out, making the AC work harder than necessary. A professional can seal any leaks that are found.

How to clean your AC unit

If your AC unit isn’t blowing cold air, one of the first things you should check is the air filter. A dirty air filter will restrict the airflow to your AC unit, which can cause it to freeze up.

To clean your AC unit’s air filter, first turn off the power to the unit. Then remove the filter and rinse it with warm water.

Let the filter dry completely before putting it back in place. If cleaning your AC unit’s air filter doesn’t solve the problem, you may need to call a professional for help.

How to properly maintain your AC unit

Your air conditioner works hard to keep you cool all through the dry season, so it’s important to give it the care it deserves.

A well-maintained AC unit will function more efficiently and may even last longer than one that isn’t maintained. Neglecting your AC unit can also lead to breakdowns, which can be expensive to fix.

Here are a few tips on how to properly maintain your AC unit:

  • Check the outdoor unit regularly to make sure there is no build-up of debris, such as leaves or dirt. This can impede air flow and cause the unit to work harder than necessary.
  • Inspect the indoor unit (the evaporator coil) and clean it if necessary. A build-up of dust and dirt on the coil can cause it to freeze, which will negatively impact air flow and cooling efficiency.
  • Change the air filter regularly. A dirty filter can cause the AC unit to work harder than necessary, leading to increased energy usage and higher utility bills.
  • Make sure all vents in your home are open and unobstructed. Closed or blocked vents will not allow cool air to circulate properly, making your AC unit work harder than necessary.

Final Words

It can be frustrating when your AC isn’t blowing cold air as it should, particularly at a moment when you need it the most.

Fortunately, the problem may not be as serious as you might think. Review the probable causes why your unit is not chilling in this post and follow a strict routine of maintenance to keep your AC performing at optimal levels.

    Howdy would you mind stating which blog platform you’re using?
    I’m planning to start my own blog soon but I’m having
    a tough time selecting between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design seems different then most blogs
    and I’m looking for something completely unique.
    P.S Apologies for getting off-topic but I had to ask!
