How Does a Ductless Mini-Split Work?

Ductless mini-splits make it easy to cool your home without ductwork. The system functions like a central air conditioner. It includes an outdoor condenser unit that houses the condenser coils, a compressor, and a fan and one or more indoor air handlers.

Each air handler has refrigerant lines and electrical cables that pass through a small 3- or 4-inch opening to the outdoor condenser unit. Each air handler includes an evaporator coil, an air filter, a fan, and a thermostat for individualized comfort in each zone.

To provide cooling, a ductless AC system blows air from your home over the evaporator coil, then the refrigerant absorbs heat from the air so air handlers can distribute cool air. Next, the refrigerant is compressed and sent to the outdoor condenser coil, where it sheds its heat to the outside air before starting the cycle again.

Ductless Mini-Split Installation & Replacement

Ductless AC units are energy-efficient, ideal for smaller homes, and quieter than a central AC system. Plus, many ductless systems are reversible, allowing them to provide efficient, cost-effective heating in the winter, as well.

Frequently Asked Questions

How long do ductless mini-splits last?

Ductless mini-splits will usually last 10 to 15 years. To maximize the service life of your ductless HVAC system, clean the air filter often, schedule preventative maintenance, and complete repairs promptly.

Do I need a mini-split in every room?

No, you only have to install air handlers in the rooms you want to cool. If you would like to cool your entire home, placing air handlers in communal areas like living rooms or kitchens plus one in each bedroom can provide ample coverage while allowing individualized control for each zone.

How do you clean ductless mini-split filters?

Remove the filter from the air handler housing, then rinse it under cold water until the water runs clear and all the debris is removed from the filter. Use a sponge if necessary to dislodge stuck particles. Let it air dry completely, then reinstall it.
