DYI Ductless Mini Split System

Improper product selection: Let’s start with the first step which is making the proper product selection. Choosing a product based on your square footage Is not adequate. A professional contractor will start you off on the right foot with a load calculation which will ensure you get the properly sized and located outdoor unit and indoor units.

Specialty Tools: Installing a ductless system requires specialty tools that every HVAC truck has standard.

High Voltage: Ductless systems typically have 240 volts running through them and need to be properly wired to the main breaker panel with a disconnect at the outdoor unit. There are some components that even after the unit is unplugged can provide electrical shock.

Licensing is a Requirement: An EPA-certified license is required to handle refrigerant and electrical upgrades and wiring require a properly licensed electrician to pull permits and complete the work.

Voided Warranty: Ductless system warranties become void if not installed by a licensed pro.

Poor Support: DYI systems bought online lack the robust technical support, access to parts, and proper warranty backing that professional-grade and professionally installed systems do from local distributors and manufacturers. HVAC professionals typically avoid getting involved in repairing DYI systems because of the lack of support, warranty issues and poor components.

Damage to home envelope: Installation requires drilling holes through the exterior of the house, potentially damaging gas, water and electrical lines and weatherization systems.

No rebates. Utility rebate programs require ductless mini split heat pump installations be completed by properly licensed and credentialed contractors in order to qualify for rebates.
