Mini-split systems have become increasingly popular, especially among residential clients. As an HVAC professional, installing these systems confidently can help you keep your customers happy. So, what are some things you should always knowbeforeyou install a ductless mini-split system for a client? Let’s get started!
Before you can install a mini-split system, you’ll need to provide your client with a quote. This quote should include the system itself, the cost of any other materials required to install it, and labor. Expenses for mini-split systems can vary based on many factors, ranging from BTU and tonnage to the number of zones and equipment features. In general, however, a dual-zone mini-split system for a residential building willcost between $2,000 and $14,500.
One of the more challenging aspects ofinstalling a mini-split systemis sizing the unit to suit the home known as a load calculation. In general, the size of the unit will correspond to the square footage that needs to be air-conditioned. For smaller spaces (less than 500 square feet), a 12k BTU system will likely suffice. However, older homes with poor insulation or homes with high ceilings may require a more powerful unit of 18k BTU, 24k BTU, or 36k BTU. Thus the importance of a load calculation on the home to confirm it can handle the load of the space.
As part of any ductless mini-split installation project, you’ll need to select a location for the indoor unit and outdoor base unit. For the indoor unit consider the direction of airthrow and not to place it near a heat source like a stove or window. Typically, the outdoor unit will take up around eight square feet (give or take). However, the concrete pad on which the outdoor unit rests must be completely level, so be sure to consider this as you choose a location for its installation. It may be easier to attach the unit to the side of the home with a mounting bracket in some cases.
The exact tools that you need for a mini-split installation job can vary a bit, but generally include a:
In addition to these tools, you may also need the following materials:
Another challenge of installing a mini-split system is getting power to the unit destination depending on the location. These systems do not draw a lot of power from the circuit — confirm the circuit is not underpowered, so the unit will run properly. It is necessary to install a dedicated circuit specifically for the ductless system. If this is not something you’re capable of doing on your own, you’ll need to bring an electrician to handle this part of the project.
