Gree mini-split not cooling

Many things can point to a Gree mini-split AC not cooling properly, such as malfunctioning components, obstructions in the outside or inside units, and the wrong temperature settings.

Having a mini-split air conditioning system in one’s home can offer the best in cooling. Mini-split systems have an indoor air handler and an outdoor condenser unit. Hot air is extracted from the home in order for cooler air to be released inside.

The worst thing that can happen on a hot day is for the air conditioner to not cool at all. It can be a huge inconvenience as this means your indoor temperatures will be scorching and uncomfortable, until the issue is fixed.

Gree mini-split air conditioners

Gree is a manufacturer of mini-split system air conditioners. Gree mini-split systems deliver zone-specific climate control and cool or heat rooms quickly, maintain a steady temperature, and are more energy-efficient than many other types of ACs.

These units are built for reliability and are Energy-Star certified with units that are up to 38 SEER rated. But Gree mini-split air conditioners also run into issues that result in them not cooling or in them blowing warm air instead of cool air.

When this happens, understanding the cause may help you get the problem fixed sooner rather than later.

Gree mini-split not cooling

If your Gree mini-split air conditioner has been on, but it does not seem to be cooling, your unit is likely not broken, but rather, it is possibly encountering issues that are not allowing it to cool the air effectively.

All types of air conditioners can experience these types of issues with cooling inefficiencies, and most times, the causes are easily fixable, so owners can get their systems back in working mode and enjoy efficient cooling or heating again.

If your Gree mini-split system is not cooling, there are a number of issues that may be causing this. Some are small, while others may be more serious and may need urgent attention from a professional.

The main issues will likely be that the inner components of the unit are not in the right condition to cool as it should.

Your unit contains vital parts that play a major role in the cooling cycle and the unit’s ability to blow cooler air into the room, and if they are not in the right state, it will affect the unit’s cooling capability, leaving the space warmer (or colder) than it should be.

The important components of the unit that can be the cause of your Gree not blowing cool air include the air filters, the refrigerant, and air ducts.

Sometimes, simpler things such as the temperature not being accurately set to cool, or the fan speed being set lower, can cause the unit not to cool.

Dirty air filters, leaked refrigerant, or leaking air ducts

Some of the most important components of your air conditioner could be the problem. If your air conditioner has dirty air filters, they are probably clogging the evaporator coils and preventing proper cooling. This is why it is imperative that you clean the filters of your AC routinely.

  • Clean the filters using a vacuum, or by scrubbing the filters carefully with a soft brush under lukewarm water.
  • Clean the evaporator coils with a coil cleaner and a coil brush

Refrigerant is the cooling agent in the air conditioner. When the refrigerant quantity is reduced (which it should not be), then there is likely a refrigerant leak causing the unit to not cool efficiently. Refrigerant needs to be checked by a professional to fix the problem in this case.

If your Gree mini-split AC is a ducted system, then you should check the ducts for any air leaks, as air leaks can also cause the unit to not cool efficiently.

Obstructions at the vents or at the condenser unit

Sometimes, the Gree mini-split air conditioner may be obstructed in places where cool air is supposed to be blowing air. The outside condenser unit can easily accumulate dirt that can block it from the outside.

It is important to go look around the outside unit for dirt, debris, or leaves that may be interfering with the unit and remove them. The inlet and outlet vents should also be checked for any obstructions.

Temperature settings and heat generating sources can hinder cooling

Another thing to check if your Gree air conditioner system is not cooling is whether the temperature settings are suitable and set for cooling.

Check the temperature settings to see if the unit is set at a temperature and mode where it should be cooling.

If there are heat-generating sources in the room such as other electrical appliances, they may make it hard for the unit to cool adequately. Switching off unnecessary heat sources can help reduce the strain on the unit.
