Yes. Mini-splits are our most requested installation on Maui because they cool individual rooms efficiently without ductwork and many models also heat.
If the system is under 10 years old and the repair costs less than a third of a new system, repair usually makes sense. Older R-22 systems and units with salt-damaged coils are usually better replaced.
Yes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.
