Do-It-Yourself mini-split ductless systems are quickly becoming one of the most popular HVAC options thanks to a combination of cost effectiveness and energy efficiency wrapped in a straight-forward design that is easy to install. In this article we’ll walk through the features of benefits of these unique heating and cooling systems.
What is a DIY Mini Split?
In general, mini split systems do not rely on ductwork to circulate hot and cold air and instead rely on an outdoor compressor and indoor air handlers that sit within rooms (or zones) to distribute heating and cooling. The outdoor unit contains the condenser and the compressor. This is linked by a copper refrigerant line set to the indoor unit; which contains the evaporator coil and air handler that sends cooled air into the room.
DIY mini split systems are single zone air conditioning and heating systems that can be installed by the homeowner, without the need for HVAC certification.
DIY mini-splits are ideal for homeowners or business owners who need to cool a single zone or room. The line set on a DIY system comes pre-charged, so there is no need for HVAC equipment or knowledge. Anyone with moderate DIY skills can install these. Just remember to keep in mind that not all ductless mini-split systems are DIY mini-splits. A mini-split system that is not packaged as DIY uses custom lengths on the refrigerant line sets that need to be installed and charged by a trained HVAC installer.
What are the benefits of a DIY Ductless Mini-Split System?
There are several key advantages that DIY ductless mini-splits have over traditional split systems. For starters, mini-splits are more energy efficient with higher SEER than traditional AC split systems. This makes mini-splits more cost effective since you save money on both the installation and the operation.
Since DIY systems come with pre-charged line sets and there's no ductwork to install you can retrofit almost any existing space. This means you can heat or cool your workshop to a precise temperature completely independent of your office space.
Ductless air conditioning and heating also provides multi-stage filtration that can drastically reduce dust, bacteria, pollen, allergens and other harmful particulates in the air.
And since you can install these yourself, you can save money on the costs of the mini split installation.
Is a Single-Zone ductless mini-split right for you?
If you're debating whether a DIY ductless mini-split is right for you just follow these simple guidelines:
1) Make sure the mini-split is packaged as DIY installable.
2) Confirm that the ductless mini-split you plan to purchase is specifically packaged as DIY approved.
3) Are you able to follow instructions and comfortable using basic hand tools?
4) Be honest about your comfort level with hand tools and your ability to understand basic electrical wiring – including the color coding of wiring schematics.
If you're planning to install a DIY ductless mini-split then you should have a drill and a standard set of drill bits, a 3-inch hole saw, a hammer, slotted and Phillips screwdrivers, needle-nose pliers, a standard set of hex keys, adjustable wrench, torque wrench, utility knife, 24-inch level, safety glasses, and work gloves.
We hope you've found this article and video helpful in determining if a DIY ductless mini-split system would be the best choice for your heating and cooling needs.
