Why Is My AC Not Blowing Cold Air

If you’re finding it hard to sleep or work due to the heat, an air conditioning unit can help. Not only does this provide better living conditions for those who need them, but it also makes your home more comfortable with less risk of discomfort from excessive sweating during hot days/nights! But if your AC goes out and stops blowing cool air, you might feel sticky from all that sweating. It’s important to have this fixed quickly because otherwise, things will only get more uncomfortable than they already are now.

Let’s look at the different ways your AC unit can stop blowing cold air. Some are simple and quick, while others will require professional help from an AC professional in this field of work- but don’t worry! You’ll know what to do when troubleshooting any problem with AC service because we’ve got all tips right here for you below:

Clogged Air Filter

The system’s air filter helps to keep the air conditioning system clean and functioning at its best. Suppose you don’t change your dirty air filter often enough. In that case, they can get clogged up with dirt, restricting airflow for any given unit – resulting in less energy efficiency or, even worse, no cooling whatsoever!

The aircon filters should be changed every three months to prevent dirt and bacteria from accumulating on them. If your pets are indoor animals, you may need to change them more often! To replace clogged filters yourself is easy if you have some basic know-how about which type of equipment works best for this task

Refrigerant Leaks

Your central air conditioner is running low on refrigerant, and it could be a problem. A leak on refrigerant lines will keep your AC from working properly and cause other issues in homes around you! If someone smells something funny coming out of their home’s vents or if there are visible signs of refrigerant leak like liquid spilling all over, then they should contact an AC professional right away because not fixing this issue could lead to bigger problems down the road such.

Problems with Evaporator Coil

The air filter in your air conditioner does its best to keep the evaporator coil clean and operating at peak performance, but even they will wear out over time. The evaporator coils keep the cooling system clean and running at peak performance, but even they will wear out over time.

The constant moisture can cause problems with mildew or mould on an indoor evaporator’s coil as well; if there isn’t enough refrigerant in your air-conditioning unit, then you may experience freezing up of these parts too! Which is one of the common causes of ac not blowing cold air.

To keep your air conditioner running efficiently during the hot summer season, ensure the evaporator is clean. If you start to wonder why your AC is not cold, it might be time for an annual check-up on the refrigerant system.

Make sure all dirt builds up around its exterior by giving them regular washings at least once per six months – or whenever they need attention, depending upon how often things go wrong

Condenser Unit

The condenser unit also has an important role in maintaining constant humidity levels for interior comfort and should never wear out unless there’s some other major issue with our home’s HVAC system.

Cleaning up your outdoor condenser unit is something you can do on your own! We recommend using soap and water to wipe away the dirt gently. You could also use a hose with low pressure, but make sure not to abuse or bend anything while cleaning because it’s possible that one little bump could break something internally, which would result in poor performance from then onwards, preventing your air conditioner from blowing cold air.

Clogged Vents

Just like an air filter clogged and restricts airflow, a blocked or cloth vent can do the same thing. A return-air register takes in ambient room temperature while supply vents blow conditioned cool breeze into your house throughout its length – but something obstructs the ductwork.

When something is obstructing the vent of a central air conditioning system, only that room will feel warmer than other areas of your home or office. This can be an indication there may have been a problem with air circulation in ducts which supply conditioned airflow around our homes and businesses – so make sure you check for any closed vents!

Thermostat Settings

If you’re having trouble with your air conditioner, misconfigured thermostat settings likely cause the problem. The first step in diagnosing this issue would be confirming whether or not there have been any changes to how the cool/heat setting was set on their device; if so, we need to find out what those adjustments were before continuing forward!

If the thermostat is not working, a few things could be causing this. First, you’ll want to check and make sure it’s batteries before replacing anything else because if they’re dead, all your equipment will stop functioning! If those don’t work, call an AC professional for help right away.

Wrong Air Conditioner Size

If you’re looking for a new air conditioner, be sure to get one that fits your needs. An improper fit can cause all sorts of problems, from not cooling properly to wiring issues! When shopping for an air conditioning unit, it is essential to consider your space needs.

If you have a small house or room with low ceilings, make sure that whatever size machine matches this perfectly before buying so as not to overwhelm its performance capacity and prevent the proper functioning of the AC/ ventilation system in question.

Check for Ice Build Up

Ice build-up can be a serious problem for air conditioning units. This will result in low cooling performance over time and may cause other more major issues such as overheating, failure of components due to salt build-up on exterior surfaces, which causes corrosion, and reduced airflow leading to inefficient operation.

Common Troubleshoot You Can Do

Clean Dirty Air Filters

The dirty air conditioner filter will make the device work harder and less effective. As a result, there is an increased possibility for your electricity bills to go up, which means you won’t get that cold breeze on those hot days! Make sure it’s washed at least once every month.

The Thermostat Is Set To Cool

If you notice that your air conditioner is not blowing cool enough wind, it might be because the unit’s temperature setting isn’t high enough. Before calling an expert for help, ensure this problem happens in a room with low ambient temperatures.

Circuit Breaker Box

The problem with your air conditioning unit could be due to a circuit breaker box. Most units have two parts- an indoor unit and an outdoor device. If they’re not appropriately powered together, there will be no way for this machine to provide cold air inside, so make sure everything’s in working order by resetting any tripped breakers if necessary before seeking assistance from professionals!

Proper Maintenance is Important

The easiest way to keep your AC running smoothly year-round is by performing routine maintenance on it. This includes cleaning and replacing filters, oiling fan motors or removing accumulated dust obstructing air flow into the machine’s cooling system.


Your air conditioner is a vital part of your home; if it’s not working correctly, you might feel some hot heat. There are many reasons that can cause this problem, including easy-to-fix (like changing out filters) or more extensive repairs depending on what needs fixing!
