If your mini-split is not blowing cold air, it could be due to a number of reasons. We have compiled a list of common causes for this problem and how you can fix it.
Remember that these solutions are general tips and may not apply to every situation. Contact your local Energy Monster team if you are having problems with your mini-split, or if it’s only blowing out warm air.
Here are some common reasons for your mini-split to not work:
- The temperature was not set correctly on the thermostat.
- The indoor unit may be dirty and need to be cleaned.
- The outdoor condenser may be faulty or need to be repaired.
- The indoor air handler may be a fault and require maintenance.
- The mini-split may be low on refrigerant or leak in the refrigerant lines.
Most Common Causes For a Mini-Split Not Blowing Cold Air
It’s the middle of summer and it’s sweltering hot. The last thing you want to deal with is your air conditioner not blowing cool air, making your house hot and musty. Finding the root of the problem can be frustrating, so we’ve compiled a list of the most common problems with your ductless mini-split.
Temperature Not Set Correctly
If your mini-split isn’t working properly, the most common reason is that the temperature hasn’t been set correctly between the thermostat and the indoor air handler. It’s important to check that the thermostat is set to the correct temperature to ensure that your mini-split is working efficiently. If the thermostat is set too low, the indoor air handler will repeatedly cycle on and off without reaching the desired temperature.
Conversely, if the thermostat is set too high, the air handler will run continuously without ever reaching the desired temperature. In either case, your mini-split will work harder than necessary, and your energy bills will increase.
The good news is that if setting the temperature fixes the issue, you won’t have to invest in costly mini-split repair services. You can ensure that your mini-split is working as efficiently as possible by taking a few moments to check the thermostat settings.
Indoor Air Handler Dirty
If your indoor unit is dirty, the first thing you should do is clean the air filter. One giveaway is if your ductless mini-split smells musty. If the problem persists, it may be due to a build-up of dust and dirt on the evaporator coil or in the condensate drain line.
A dirty indoor unit can lead to poor indoor air quality. The problem can be easily remedied using a specifically designed cleaning solution. If you’re still having trouble, it’s best to call a professional for assistance. With just a little preventive maintenance, you can keep your mini-split running smoothly for years to come.
Faulty Outdoor Unit Condensor
The condenser is responsible for removing heat from the refrigerant, while the evaporator absorbs heat from the air inside the home. If the outdoor unit condenser is not working correctly, it can prevent the system from cooling the home effectively.
Potential causes of a faulty condenser include old age, dirt and debris build-up, and damage from weather events. In most cases, a trained technician will be able to handle all your mini split repair needs, including replacing the condenser and restoring the mini-split system to its full capacity.
Fault in the Indoor Unit
The indoor unit consists of a fan, evaporator coil, and air filter. If any of these components are not working properly, it can prevent the unit from cooling the air effectively and you may find your unit blowing hot air.
In this case, you may need to call one of our technicians and have a part replaced or have your indoor unit maintained.
Low on Refrigerant or Refrigerant Leak
Low refrigerant or a refrigerant leak can happen for several reasons, such as a hole in the unit, incorrect installation, or old age. If you have a leak, it’s essential to have it repaired as soon as possible, as it can worsen over time and cause permanent damage to your unit.
If you’re low on refrigerant, you may need to recharge your system. This is typically a simple process that can be done by a professional, but it’s always best to consult your owner’s manual before attempting any repairs yourself.
By troubleshooting your mini-split and taking care of any issues that arise, you can keep it running smoothly for years to come.
Common DIY Fixes if Your Mini-Split Air Conditioner Isn’t Blowing Cold Air
If your mini-split AC unit doesn’t blow cold air, there are a few potential fixes you can try before calling a professional:
- Check the air filters and make sure they aren’t dirty or clogged. Replacing the filters regularly will ensure you have good indoor air quality.
- Check the outdoor unit to make sure there isn’t any debris blocking the airflow. If there is, clear it away.
- Check the thermostat to ensure your air conditioning system is set to the correct temperature.
If all of these things are in order and your mini-split still isn’t blowing cold air, you may need to call a professional for help.
