Knowing how to do basic troubleshooting on your portable air conditioner can help to extend the life of your unit and keep it running efficiently. Here are some of the most common problems encountered with a portable air conditioner and what you can do.

The Unit Is Leaking

Occasionally, you will notice your portable air conditioner leaking. Condensation builds in your unit as it is used and it usually is dispelled through a drain hose. However, the hose can sometimes become clogged and lead to water building up and leaking onto the floor. Check your owner's manual for the location of your hose. Once you have found the hose, remove it and clean it. 

If the leaking continues, check the water reservoir. The reservoir also collects condensation as the unit runs. Empty the reservoir and put it back into position. 

The Unit Is Frozen 

Another common problem with the portable air conditioner is that ice can build up on the inside. An ice buildup is usually a sign that the filter is dirty. Remove the filter and wash it. Allow it to completely dry before replacing the filter. Wait a couple of hours before turning on the portable unit to allow the ice to melt and the unit to dry. 

If the problem persists, it is possible that the refrigerant levels in the portable unit need to be checked. Refrigerant can be tricky, so call on a professional HVAC technician to fix your unit. 

The Unit Is Not Cooling the Room

When the portable unit is not cooling the room in which it is used, ensure it is not being blocked by furniture or any other objects. You also should check the filter and vacuum its vents to ensure there is no dust buildup preventing it from blowing air efficiently. 

Another possibility is that it is not large enough for the room. Check the BTU rating for the unit and ensure that it is sufficient for the room. Refer to your owner's manual for the recommended square footage of the room for your unit. If the unit does not have enough BTUs for the space, you will need to either move it to a smaller room or purchase an additional unit.  

Even though your air conditioner is a portable unit, it still requires a certain amount of care. To ensure that it is running at its best, have it serviced on a regular basis by a HVAC technician like Custom Comfort.
