1) Check Thermostat Setting
The first thing to check when your air conditioner is not working as it should is the thermostat setting. If the thermostat is set to a temperature that is higher than room temperature it may not even turn on at all as it will detect that the room’s temperature is lower than the set temperature. It may seem obvious but it happens.
Reset the temperature on your thermostat and change it to a few degrees cooler than the room temperature. Note: It can take a few minutes before you feel any cool air coming out so don’t panic right away.
Top Tip: If your air conditioner is not turning on you may also want to check the batteries in the thermostat.
2) Check Air Filtration
Another potential cause of an air conditioner not blowing cool air is a filtration problem. If the air filter in your air conditioner is clogged it will restrict air flow and prevent cold air from circulating in your home. If you’re not already regularly checking and changing the filter in your air conditioner it is more than likely very clogged by now.
Luckily, this is a relatively easy fix. Simply check the air filter in your air conditioner to see if it is clogged with dust and other allergens. If it is, clean it down with warm soapy water or replace it if your AC takes disposable filters. Note: ensure that the filter is completely dry before reinserting it into the air conditioner.
Once you have cleaned or replace the filter continue to regularly check it (once a month or so) and change/clean it as needed.
3) Check Outdoor Unit
The outdoor unit of an air conditioner expels the heat that is absorbed from the warm indoor air. Similar to the air filter, if the outdoor unit is clogged or covered in debris it can cause air flow problems. And if the outdoor unit is unable to release the warm air, the indoor air will not cool down.
To prevent this, ensure that the area around the outdoor unit is kept clear of leaves, twigs, and debris. Keep all nearby gardens weeded and trimmed and remove any overhanging branches. You may also want to invest in a weather proof air conditioner cover to employ when the air conditioner is not in use.
4) Check Leaking Refrigerant
Another possible cause of an air conditioner that no longer produces cool air is a refrigerant leak. In an air conditioner, refrigerant should never run out as it just continuously cycles through the system. However, if your air conditioner has a refrigerant leak, there may not be enough refrigerant left in the system to effectively absorb the heat in the air.
Some signs that your air conditioner may have a refrigerant leak include a hissing noise when the air conditioner is on, an icy buildup on the outside of the unit, or if your air conditioner takes longer than usual to cool the room. If you suspect that your air conditioner has a refrigerant leak stop using it immediately and contact your local Brisbane air conditioning experts on 0403 254 272.
