How Does a Ductless Mini-Split Work?

Ductless mini-splits are a great way to cool your home without ductwork. The system consists of an outdoor condenser unit and several indoor air handlers. It uses evaporator coils to cool the air before distributing it throughout your home.

Each individual air handler has the power to provide zoned cooling to the room it’s in, allowing you to customize your comfort. Ductless heat pumps can also provide heating during the winter to streamline your home comfort.

Frequently Asked Questions

What are the benefits of ductless mini-splits?

Because each air handler can be controlled independently, ductless mini-splits offer highly customizable zoned cooling. This not only significantly improves your comfort, but it also helps you save money and energy by only operating in the rooms that you need cooled.

How long do ductless mini-splits last?

With routine maintenance, your ductless mini-split can last 10 to 15 years.

Why is my ductless mini-split leaking water?

Common causes include dirty air filters, clogged condensate lines, and cracked drain pans. Call your HVAC technician to get an accurate diagnosis.

How do you clean ductless mini-split filters?

Turn off your unit and open the air handler. Gently slide the filter out and put it in the sink. You can remove any dust and debris by spraying it with water. Let the filter dry and then slide it back into the handler.

How are ductless mini-splits different from heat pumps?

Unlike a heat pump, a ductless mini-split does not require ductwork. However, your ductless mini-split can operate like a heat pump to both heat and cool your home.

Do I need a ductless mini-split in every room?

No, you don’t need an air handler in each room. Your HVAC technician can help you determine how many air handlers you need and where to install them to ensure that you can get the cooling comfort you need throughout your home.

Why is my mini-split not blowing cold air?

Insufficient cooling from your mini-split can be frustrating. Troubleshoot the issue with a few simple steps:

  • Confirm that the system is on. If it’s not running at all, you likely have an electrical issue. Check the circuit breaker and the outdoor unit’s power shutoff switch to ensure that power is coming to the unit.
  • Check your filters, indoor coil, and blower wheel for significant dust and debris. Heavy buildup can weaken airflow.
  • Look for a refrigerant leak. Check for frost or ice buildup on the outdoor unit.

If flipping the breaker or cleaning the filter doesn’t resolve the issue, call for HVAC repair.
