It's 90 degrees outside and you need a break from the heat. The thermostat is set to 65, but your home feels like 80. And then you realize that something is wrong with the air conditioning.
No need to panic. Luckily, whether you haveor a window unit, there are a few ways you can fix cooling problems without calling the mechanic. Do not worry, these do not require that you do something dangerous or technical. These are simple fixes that anyone can try.
Problem: Your room or house takes longer than usual to cool off.
Fix: It's probably time to clean oron your air conditioner, depending on whether you have a reusable or disposable filter.
Remove the filter (you may need to check the AC manual to find it) and hold it to the light. If you can not see the light, it's clogged. This obstructs airflow and your device is less efficient.
If you have a disposable filter, simply turn it off with a new one. If it is a washable filter (check your manual again), fill a tub with a few inches of warm water and a few drops of mild dish soap. Let the filter soak for 1
Check if the unit is frozen
Problem: Your AC device is blowing air, but it's room temperature or warm room will not cool.
Fix: Sometimes, with an air-conditioning system running continuously to keep up with the heat, the evaporator coil freezes. Place your hand on the side of the device near the filter. If it feels very cold, it is probably frozen. You can even see ice hanging from the unit.
Turn off the cooling mode and turn on the fan to de-ice the evaporator coils. While you're at it, make sure that the filter and coils around the filter are dust-free. Dust can also cause an air conditioner to freeze.
Defrosting can take a few hours, so go to a movie or go to the mall while you wait.
Very important: Do not use your air conditioner in the cool environment if you suspect that it is frozen. This can ruin the compressor (an important component), which leads to expensive repairs. Either switch on the fan only or switch off the entire unit until the ice melts.
Check the vents
Problem: They have central air and one room not cool, but the others are.
Fix: That may seem obvious, but check the openings in the room, especially if they are on the floor. Debris could have fallen in and clogged the air passage, or a toddler might have clogged game block in the mouth (it happened). Either way, unscrew the breather plate and scoop out anything that could obstruct the airflow.
Problem: You've tried all these fixes and the AC still does not cool properly
Fix: The outer vents may be clogged. Disconnect the window unit or turn off the circuit breaker for your outdoor unit. Spray the part of the unit that is outside the window or your house with a water hose to remove dirt, leaves, or bugs that could obstruct the flow of air. You can also use a large cleaning brush to remove dirt from the grilles.
