The Insider's Guide to Pre-Charged HVAC Units

As an expert in the HVAC industry, I have encountered numerous questions and misconceptions about pre-charged HVAC units. One of the most common inquiries I receive is whether these units come pre-charged with freon. The answer is yes, but there are some important things to know before installing or handling these units. First and foremost, it is crucial to understand that all air conditioning systems are pre-charged with refrigerant. This means that they come with a specific amount of refrigerant already inside, typically enough to cover a volume of approximately 20 feet of refrigerant lines.

This is done to make the installation process easier and more efficient for both the installer and the customer. However, it is important to note that handling refrigerants requires certification from the Environmental Protection Agency (EPA). This certification ensures that individuals are properly trained and equipped to handle these potentially hazardous substances. So, if you are planning on installing or working with an HVAC unit, make sure you are certified by the EPA. Now, let's address some other common questions and concerns about pre-charged HVAC units.

The Advantages of Pre-Charged Units

One of the main benefits of pre-charged HVAC units is that they save time and effort during installation. As mentioned earlier, having the refrigerant already inside the unit eliminates the need for additional steps and equipment during installation.

This not only saves time but also reduces the risk of errors or leaks during the process. Additionally, pre-charged units are also more convenient for customers. They can simply purchase the unit and have it installed without having to worry about buying and handling refrigerant separately.

The Follow Me Button

Now, let's address the question about the Follow Me button on the MRCOOL remote control. This feature allows the unit to sense the temperature around the remote control and adjust accordingly. This means that if you are sitting in a specific area of the room, the unit will adjust its settings to ensure that you are comfortable.

This is especially useful for those who want to practice social distancing while still staying cool and comfortable. However, it is important to note that this feature may not be available on all models of MRCOOL units. So, make sure to check the specifications before purchasing.


In conclusion, pre-charged HVAC units do come with refrigerant already inside, but it is important to be certified by the EPA before handling them. These units offer many benefits, such as saving time and effort during installation and providing convenience for customers. And for those wondering about the Follow Me button on MRCOOL units, it is a useful feature for maintaining comfort while practicing social distancing. As an expert in the HVAC industry, I hope this article has provided you with valuable information about pre-charged units.

Remember to always handle refrigerants safely and responsibly, and enjoy your cool and comfortable space!.
