5 Causes of An Air Conditioner Only Blows Warm Air

Is your air conditioner blowing warm air? It is never a good thing. If you’re experiencing this, it’s likely that there’s something wrong with your AC unit. In most cases, it will result in an uncomfortable home and increased energy consumption. Here are five possible causes of an air conditioner blowing only warm air and what you can do about them.

Dirty air filter

One of the most common reasons why an air conditioner blows only warm air is because the air filter is dirty. A dirty air filter will block airflow and prevent your AC unit from operating properly. To fix this, simply clean or replace the air filter if it’s replaceable. On the other hand, you can use warm air and mild soapy water to clean the air filter.

However, the best way to prevent this is by scheduling a regular aircon servicing. With this, a professional will be able to clean the air filter and other parts of the AC unit. Doing so will help prolong its lifespan and prevent it from breaking down.

Broken thermostat

Another possible reason for an AC blowing only warm air is a broken thermostat. If the thermostat is broken, it will be unable to accurately measure the temperature of your home. As a result, the AC unit will either overwork or underwork itself, leading to blowing only warm air.

The best way to fix this is to hire a professional to replace the thermostat.

Compressor issues

The compressor is one of the most important parts of an AC unit. It’s responsible for circulating the refrigerant throughout the system. If the compressor is not working properly, it will prevent the AC unit from cooling your home effectively.

Compressor issues should be fixed by a professional like aircon service Singapore. Attempting to fix it yourself can do more harm than good.

Clogged drain lines

Another common cause of an AC unit blowing only warm air is clogged drain lines. The drain lines are responsible for removing the condensate from the AC unit. If they’re clogged, it will prevent the AC unit from draining properly, causing it to blow only warm air.

To fix this, you’ll need to clear the clog from the drain lines. Most people prefer to do an aircon chemical wash to clean the drain lines, so it will also remove the buildup of mould in the lines.

Refrigerant leak

Last but not least, a refrigerant leak can also cause an AC unit to blow only warm air. The refrigerant is responsible for cooling the air inside your home. If there’s a leak, it will cause the AC unit to lose its cooling power. As a result, the AC unit will be unable to cool your home effectively, causing it to blow only warm air.

A refrigerant leak is hazardous to health and must be handled by professionals. Do not try to fix it by yourself.

These are some of the most common causes of an AC unit blowing only warm air. If you’re experiencing this, make sure to check for these possible causes so you can fix the problem right away. Also, don’t forget to schedule regular AC servicing to prevent this from happening again in the future.
