Check Your Thermostat

To begin with, sometimes things aren’t as complicated as we believe them to be. Your aircon might not be blowing cold air for one simple reason and that’s because you haven’t adjusted your thermostat settings properly.

Whether it’s set to “AUTO” or “ON”, a good idea is to simply reset the thermostat and program it a few degrees lower than the home’s normal temperature. Chances are high that this will work. If there’s still no cold air coming out, then you should move on to the next issue on the list.

Tripping Circuit Breaker

But don’t be too quick with presuming the worst. If the problem isn’t in the thermostat settings, it might just be another simple mishap – a circuit breaker tripping.

Breakers trip all the time, especially when there’s too much electricity flowing through it. Typically, every aircon unit is connected to two circuit breakers – one for each of the panels. The problem is that if the outside breaker trips, the condenser coil won’t work, thus leaving your system unable to cool the air in your home.

You can try to fix the issue by resetting the breaker. If it happens again, don’t try to repeat the procedure because it may cause unwanted damage to your aircon. A wiser solution would be to call an expert. He’ll examine the faulty circuit breaker safely and deal with the problem using proper equipment.

Your Air Filter Needs Replacement/Cleaning

Contrary to popular belief, getting an air conditioning system installed in your home doesn’t mean you’ve added yet another appliance or smart gadget. Aircon units require proper care and most of all, regular maintenance.

With this being said, you should check the air filter every now and then. Or at least once a month, to be precise. Leaving your air filter dirty will eventually start impeding the airflow significantly. As a result, you won’t be able to feel the cold air.

To deal with this, you don’t need any special knowledge of air conditioning. Simply, replace your dirty filter for a fresh one. If it’s washable, just clean it. Getting in the habit of repeating the procedure each month will save you a lot of headaches.

Ultimately, it will ensure your air conditioner works at peak level and blows cold air when needed.

There’s a Refrigerant Leak

Perhaps, the refrigerant gas, or the coolant, is the “ingredient” that makes air conditioners blow cold air. Because it’s an essential part of the cooling process, it might be the very reason why your aircon isn’t blowing cold air. Here’s why:

Since the refrigerant cycles between the indoor and the outdoor panels, a leak can reduce its level somewhere in the circuit. As a result, your aircon will be left without enough coolant to absorb the heat, thus making it unable to blow cold air.

You can easily identify the problem by checking whether there’s an ice buildup inside the air conditioner. You might also hear an unusual hissing noise while your appliance is working. Another indication might be when your aircon unit is blowing cold air, but it takes too long to cool the room.

In such cases, you should call a professional aircon technician to troubleshoot your aircon unit. Because refrigerant gas is hazardous, you shouldn’t try to fix it yourself. Instead, you should always rely on qualified specialists to top up your aircon refrigerant gas.

Check for any Ductwork Leaks

Along with the refrigerant leak, there’s another type of leak that may also impede your aircon from working properly. Because air travels through a series of air ducts before getting to your room, poor sealing and loose insulation can cause air leakage.

This, in turn, will reduce your air conditioner’s efficiency. If the problem persists for long enough, the leak may start expanding. This will not only leave you with no cool air at all but it will also put extra load on the aircon.

To prevent this issue from causing permanent damage to your aircon, you should schedule an inspection by an aircon technician. Of course, the timely action will cost you a small amount of money, but it will save you a lot more in the long run. Moreover, it will bring back the cold air into your room.

Dirty Aircon Condenser Coils

The condenser coil is yet another important part of the air conditioner that requires regular maintenance. Since it’s located in the outdoor unit, it’s prone to accumulating dirt and debris. As you may think, this doesn’t usually end well for the aircon unit.

Your air conditioner will have to work much harder to compensate for the loss of power. Over time, it can start overheating and shutting off until it breaks down totally.

Unlike gas topping up, you can try and solve this problem on your own by gently washing the inside of the outer panel with soap and water. Just be careful not to bend or break the fragile aluminum parts.

For better results, it’s best to call a professional to check and fix the issue. If you have some extra bucks, you can buy a weatherproof cover to protect your aircon when it’s not in use.

In more severe case, you may require an aircon chemical wash service or aircon chemical overhaul service.

Your Aircon Doesn’t Fit Your Room Size

Sometimes, the problem may be rooted in one seemingly insignificant mistake. If you didn’t do your research or you just ignored the retailer’s recommendations, you might have bought the wrong aircon for your room size.

As surprising it may sound, improperly sizing is one of the common reasons why your aircon isn’t blowing cold air. If your air conditioning system BTU capacity is too small for your room, it may blow cold air, but it just won’t be enough.

And the only way to deal with this problem is to replace your conditioner with a machine that will fit your room size. In short, get a professional aircon installer when you are buying a new aircon unit for your place!

Final Thoughts

To conclude, an aircon not blowing cold air is no doubt a huge inconvenience for everyone that has to struggle through the sweltering summer heat. Whether the cause is simple as a dirty air filter and wrong thermostat settings or more complicated, taking some precautions may reduce the chance of experiencing such an issue.

Therefore, always trust your local aircon company and don’t be afraid to ask for professional help. Things such as condenser coils, refrigerant gas, compressors, and wiring are no joke and they should be handled by well-trained technicians.
