Aircon Isn’t Blowing Cold: Why And What To Do

Does your aircon isn’t blowing cold air?

In the scorching heat of the summer, there are few situations worse than an air conditioning system that isn’t working properly. On a scorching hot day, the very last thing you want is for your central air conditioner to stop circulating chilly air.

This is not only exceedingly unpleasant, but it may also put your family’s well-being and the health of any animals you may have in the house in danger. You should act right away as soon as you become aware of an issue. A few factors might have an effect on the system and prevent the air conditioner from blowing cold air. The trouble with the thermostat, a blocked drain, ice accumulation, clogged filters, and other power-related concerns can be a cause of such a situation.

There is more to air conditioning systems than just the condenser unit, which is the air conditioner or heat pump that is located beside your house. There are several moving elements in typical split-system air conditioners, including copper tubing (refrigerant lines) that connects the interior and outdoor units, an indoor air handler unit (furnace or fan coil), an evaporator coil, an air filter, and a thermostat.

Why Is The Aircon Not Blowing Cold Air?

Defective Thermostat:

Your thermostat may be at fault if your air conditioner isn’t blowing cool air anymore. It’s possible for someone to accidentally bump the thermostat and alter the setting, or there might be an issue with the wiring or batteries. The refrigerated air may not be chilling for this reason.

Air Filter Blockage:

A new air filter could be all that’s required for your air conditioner. The air filter that comes with your air conditioner keeps dirt and dust out of the air conditioner’s delicate parts. It can thus ultimately block up, which is only natural. When this occurs, airflow is restricted, and you’ll probably feel less air, which you can mistake for less cooling.

If a blocked air filter is kept in your system for an extended period of time, it may cause short cycling, frozen coils, and higher energy costs.

Faulty Heat Pump:

Your outside unit might occasionally be a heat pump which is similar to an air conditioner, a heat pump has some internal differences that enable it to both cool and heat your house. It performs cooling operations identically to the condenser unit of an air conditioning system and is susceptible to the same problems, such as unclean, clogged coils, frozen coils, refrigerant leaks, compressor troubles, etc.

Unclean Condenser:

The condenser is the component of your air conditioner that is outdoors. Being outside implies that it can easily become soiled. When that happens, your air conditioner may stop blowing air or, at the very least, stop blowing any cold air. It takes place because your air conditioner needs to work harder to draw in and chill the air.

When your air conditioner stops delivering cool air due to a blocked filter, a filthy condenser might cause a similar issue.

Leak Of Refrigerant:

Chemicals like refrigerants are essential to the cooling process. When it passes between the interior and outdoor coils of the system, it transforms from liquid to a gaseous state, absorbing heat and humidity from the inside air and releasing it outside.

Depending on how serious it is, a refrigerant leak might make your air conditioner less effective at cooling your house, force it to run longer than necessary, damage or fail the compressor, or even cause the entire system to shut down.

Ways To Fix Your Aircon:

Suitable Maintenance Avoids Aircon Malfunctioning:

Your central air conditioning system requires routine maintenance, just like any other machine. Filters must be replaced, and a technician must inspect all other functional parts. Two times yearly maintenance tune-ups are often advised.

In the spring and the fall, this should take place. Before it becomes hot or cold, the technician may inspect your Aircon system and make any adjustments or repairs that are required. This not only maintains your appliance operating effectively, but it also lowers the possibility of unplanned failures and pricey issues in the future.

Compressor Cleaning:

You may clean the compressor yourself or get a professional to clean it for you if your air conditioner isn’t blowing cool air and the compressor is the problem. Cleaning by a professional is more efficient and harm-free. Be careful to turn off your air conditioning equipment if it is not cooling properly before you begin cleaning.

Verify The Thermostat:

Ensure that the setting is at least 5 degrees lower than the room’s current temperature. “Even while it appears straightforward, there’s always a chance that a different family member may have switched the appliance off or put it to “heat.”


When your air conditioner fails to do the one task for which it was created, it can be quite annoying. Given all of these frequent causes, it’s crucial to establish a regular maintenance program for your air conditioner at least once a year.

To maintain your air conditioner in top condition, this also includes routine aircon repair, cleaning, and replacements.  This is where 7 Days Aircon Servicing can assist.
