Why is my cooler not cooling enough?

If your air cooler fails to provide the usual level of cooling despite proper ventilation and maintenance, it may be due to an issue with the water tank. The tank's malfunction can hinder the cooling pads' ability to absorb water properly, resulting in reduced evaporation and, subsequently, reduced cooling efficiency.

How long does air cooler last?

You can typically expect an evaporative cooler to last between 10 to 20 years, depending on usage, maintenance, and the model you choose.

How do you know if your charge air cooler is bad?

If you notice a sudden drop in miles per gallon (MPG), it may be an indication of a charge air cooler leak. Elevated Soot Level in Oil: A leaking charge air cooler causes incomplete combustion which results in elevated levels of soot in the oil.

Should I turn off AC if it's not cooling?

When you notice that your air conditioner isn't cooling, your first action should be to turn it off. This might seem counterintuitive—after all, you want your home to be cool. However, continuing to run an AC that isn't effectively cooling can cause further damage to the system.

How to know if a thermostat is bad?
