How Do Ductless Mini-Splits Work?
Ductless mini-splits provide cooling by transferring heat from inside the home to outside through a refrigeration process. Many ductless systems use heat pump technology, so they can also provide heating.
Mini-splits have an outdoor compressor unit that transfers the heat to or from the ambient air. This type of system typically has multiple indoor air handlers, each with an evaporator system that transfers heat to or from the refrigerant.
There’s a drainage system to handle the condensation from the evaporation process. Each indoor unit has a thermostat that allows you to set your preferred temperature.

Ductless Mini-Split Installation Process
The first step in mini-split installation is determining the number of zones you need. Our installer will perform a load calculation for each. The total calculation will indicate the necessary cooling output for the compressor unit. The individual calculations will help you choose the ideal configuration for each zone.
Once we’ve acquired the required equipment, the typical installation takes four to six hours. We will:
- Remove your old mini-splits if necessary
- Determine system placement
- Connect refrigerant lines
- Connect electrical wiring
- Calibrate thermostats
- Test the system
Signs You Need Ductless Mini-Split Repair

Monitor for these other indications that there may be something wrong with your mini-split:
- High humidity levels
- Loud noises or heavy vibration

Frequently Asked Ductless HVAC Questions
What are the benefits of installing a ductless mini-split AC system?
Mini-splits are zoned for individual rooms, thereby delivering exceptional energy efficiency. The Department of Energy estimates that zoning provides up to 30% better efficiency than a central HVAC system.
Mini-splits also allow for highly flexible installations because you don’t need ductwork.
How often should I schedule maintenance for my ductless mini-split AC?
Ductless AC systems require professional maintenance annually if they only provide cooling or twice annually if they offer heating and cooling.
Ideally, you should schedule a tune-up in the spring before you need air conditioning and in the fall before temperatures drop.
