Why Is My Hisense Portable Air Conditioner Not Cooling?

When dealing with hot and humid weather, there’s nothing better than having an air conditioner in your room. Not only does it cool the room, but it also helps you to sleep and takes the excess water out of the air. However, there may be occasions when your air conditioner isn’t as cool as you want it to be. You may be asking yourself, “Why is my hisense portable air conditioner not cooling?”. There can be a number of reasons for this, so below we present some of the problems you can encounter and what you can do to fix them.

Blockages

One of the most common reasons for an air conditioner not cooling is a blockage in the air intake. This is where the fan sucks in the air from the room, cools it, and dehumidifies it. Sometimes the power of the fan can suck curtains or blinds towards the grill where they block the airflow. You should also make sure that there isn’t any furniture or anything else that would restrict the air from getting to the air conditioning unit.

If your unit has a mesh in front or behind the air intake grill, then this can sometimes get clogged by dust over time. You may not notice the drop in performance initially, but the unit will gradually become less efficient. If this grill is removable, then clean it as per the manufacturer’s guidelines. If it cannot be removed, then you may be able to use a vacuum cleaner with a small attachment to suck the dust out of the grill.

Cleaning the Air Filter

Most air conditioning units have a removable air filter. These need checking regularly as they can become blocked with particles in the air as well as dust. The Hisense manual will have instructions on how to clean this air filter and how often you should clean it. For those units that have a damaged or degraded air filter, you can find replacements on the manufacturer’s website or in stores that sell replacement parts.

Check the Thermostat

It might sound like an obvious thing to check, but sometimes the thermostat will be turned down too far to adequately cool the room. If the temperature is particularly high, then you need to turn up the thermostat to compensate. There are also some rare occasions when the thermostat itself can become faulty. These can be replaced, but you will need to open up the air conditioning unit to reach it.

The Size of Your Room

If you have recently bought a Hisense air conditioner or moved it to another room, then it may be you are using a unit not suitable for the size of the room. To find the right unit for the space, you need to look at the BTU rating.

Usually, 1 BTU equates to the amount of heat needed to raise the water temperature one-degree Fahrenheit. Most air conditioners with a BTU of 7,000 will cope well in a small room of approximately 18 square meters.

• 8,000 BTU – 100-150 sq feet or 9-14 sq meters
• 9,000 BTU – 150-250 sq feet or 14-23 s meters
• 10,000 BTU – 250-300 sq feet or 23-28 sq meters
• 12,000 BTU – 300-350 sq feet or 28-33 sq meters
• 14,000 BTU – 350-400 sq feet or 33-37 sq meters

For the best results, try to get a Hisense air conditioner that will cope with a room slightly larger than the one it is intended for. That way, you will be able to cool the room quicker and it will be able to cope effectively with higher temperatures.

So, the reason why your Hisense portable air conditioner is not cooling can be one of many, however, blockages, air filters, and the size of your room are the most common reasons. If you need to replace a part, it should ideally be carried out by a qualified repair HVAC technician.
