Port St Lucie Ductless Mini Split AC Systems

The system is composed of an exterior heat pump unit, connected to one or more interior air handling units. Each interior air handler operates independently of others, allowing for zoned comfort in all areas of the home.

With no ductwork requirements, a ductless mini-split system is a flexible and affordable option for homes with no existing ducts, new additions where ductwork has not been installed, and other applications. Ductless systems conserve energy which is lost through duct leaks in a traditional, ducted heating and cooling system - this can save your household up to 30 percent on energy costs!

Miguel came out on a Thursday to give us a second opinion on needing to replace one of our commercial AC Units. He walked us through the issues with the unit and what our options were. He sent us the quote by the end of the day with 3 options. I made a selection Friday morning and by the end of the day the new unit was installed. This was vital as we had employee's unable to work due to the temperature. He went above and beyond by giving our other unit a free maintenance while he was there as well as redirecting one of our ducts, and checking the air flow of all of the vents. I will continue to use Millennium AC for our annual maintenance.
