Mini split units are wonderful for cooling and heating a space and may run for many years without breaking down. One problem that can occur is that the refrigerant charge grows low, causing the unit to perform poorly. When this happens, the unit will require the correct amount of refrigerant to function properly. Let’s follow us to find out how to add refrigerant to mini split in this post!

How to add refrigerant to mini split?
If you bought or installed a mini split AC or Heat Pump for your grow or home with precharged lines, you’re probably not getting the maximum cooling power; here’s a DIY Mini Split ReCharge kit that works! ACs and Heat Pumps supplied with pre-charged lines are not permitted to be exported fully charged in most places.
While following the manufacturer’s instructions is simple and inexpensive, you may only be using half of the cooling power your device is capable of producing. If you properly sized your AC for your home or grow room and still feel that things are getting too warm, this could be the cause.
While the principles of recharging or topping up different mini split systems may be similar, this review of Chem Penn’s DIY mini split recharge kit from The Refrigerant Guys is for Air Conditioner or Heat Pump units that use environmentally friendly R410a refrigerant—most newer models, but it’s something you should be absolutely certain of.
Check the specs of the unit you have before using the wrong refrigerant in the wrong system. YOU MAY VOID YOUR WARRANTY BY RECHARGING THE SYSTEM YOURSELF, BUT THAT DOES NOT MEAN YOU CANNOT DO IT EFFECTIVELY AND EASILY TO GET SIGNIFICANT COOLING FROM YOUR SYSTEM.
Even if your small split air conditioner or heat pump was properly installed with a full charge, it’s quite conceivable that your system could benefit from a top-up if you have used it regularly for more than a year in your house or grow room (versus half charge with DIY pre-charged lines).
The Chem Penn DIY micro split recharge kit has everything you need right out of the box, including a convenient gauge and thorough instructions for determining and verifying the level of charge in your system, as well as up to 900 grams of R410a refrigerant.
First, ensure that your system is operational, i.e. that the compressor is working. It is critical that it does not shut down while you are completing this procedure. Simply set the thermostat to the lowest cooling setting and wait a few minutes before getting started.
Connect the threaded end of the hose connected to the gauge and canister to your system’s Low-Pressure service port (see your AC/Heat Pump installation guide or contact the manufacturer if you need to verify). If the 1/4″ SAE fitting does not fit your system, a 5/16″ adapter with Core Depressor is included.
How to Install a Mini-Split Heat Pump
Mini-split heat pumps are well-known for their cost-cutting capabilities. They are less costly to install and can save you cash over time due to the energy savings they generate, in addition to having a lower upfront outlay than most ducted systems. If that isn’t enough money saved for you, installing your mini-split system yourself can save you even more.
Mini-split systems have a relatively straightforward installation process, especially when compared to other temperature control systems, despite the fact that it may appear a little intimidating to install your own system.
The majority of mini-split systems may be installed in two days or less and only require a three-inch incision in the wall, as opposed to intrusive ductwork installation, which frequently takes several weeks. Follow these instructions for installing a mini-split heat pump to ensure a smooth installation process.
How Effective Was the DIY Mini Split ReCharge Kit?
In our testing, it worked perfectly—it turned out that the system was quite low, and we needed the full 900 grams, if not more. That’s what happens when you neglect your tiny split AC or Heat Pump for an extended period of time; live and learn.
With the aid of an infrared temperature checker, we were able to calculate that our cooling power increased by about 20%, or 10 Deg F. We should have added more than the 900 gram canister, it turns out. Consider getting an extra canister if you haven’t used your pre-charged line system in more than a few years. Anything you don’t use now can be saved for your next annual check.
FAQs
Is it possible to add 410A refrigerant to a mini split?
Yes, using the low pressure valve, refrigerant can be added to a micro split. Most manufacturers recommend recovering R410a from the system, repairing any leaks, vacuuming the unit, and adding refrigerant by weight.
Many HVAC technicians would add modest amounts of refrigerant to a low-refrigerant system, but this is not always the best option.
How Much R410A Refrigerant Is in a Mini Split?
The majority of small split units use 2-3 pounds of R410A refrigerant. The amount can vary and will be labeled on the outer unit’s face plate. The quantity the unit contains in LB will be displayed on the face plate (pounds).
