Mini split sales have been increasing around the world for a few decades. Their popularity is finally getting noticed in the United States. The more I have came across them as an HVAC technician. The more I have been impressed of their quality. They can be pretty simple to install in comparison to the more traditional package and split systems. Which usually in turn means less labor and less costs.
There are a few things to take in consideration when deciding on the mini-split system. First thing is to consider what you will be needing the adding cooling for. There are 2 types of cooling. The first is comfort cooling, which most systems operate in this fashion. They tend to only care about a specific temperature in mind and tend to run far less than the other kind. Process cooling is the other type. Process cooling is used for rooms that build large amounts of heat from a variety of sources. Many data centers and grow rooms use process cooling systems due to the amount of heat needed to be removed from the environment. Process cooling systems tend to be a little bit pricier than the more traditional comfort cooling systems, but they are built with higher quality parts to withstand the abuse of constantly running.
Next you need to decide on how much cooling you will need. For comfort cooling systems most people use the rule of thumb. For every 500 sq ft of space you should have 1 ton of cooling (12,000btus). This also depends on how tall your ceilings are for the room. If you are using a Mini-split for a grow room. I have attached a helpful link to help you determine the btus and cooling you need.
It is also important to keep in consideration how well your room is insulated. Proper seals around doors and windows can keep your system running less. Which leaves your electricity bill lower.
Many mini split systems use far less electricity than their bigger counterparts. It is important to make sure there is enough room on your electrical circuit panel too. This is not that easy to determine for the DIYer so I recommend getting an electrician or HVAC guy to help if you need more assistance. I am available for installs and servicing your mini splits with proper compensation. I have attached a few mini split systems that I would recommend getting for a comfort cooling setup.
