Think Your Ductless HVAC Unit is Clean? Think Again!

Unfortunately, it’s probably not as clean as you’d like.

What is a Ductless Mini-Split AC System?
A ductless air conditioner, which is also known as a mini-split system, incorporates two main components. The first is a cooling unit mounted to an interior wall, and the second unit is located outside of the home or business.
Refrigerant and electrical lines connect from the exterior walls to the indoor wall-mounted cooling units. Two refrigerant lines run between the two units; one line delivers electricity while the other removes condensate (water).
The outdoor unit includes an inverter-driven heat pump that cools refrigerant and sends it inside to an air handler via small lines. A wireless control unit allows you to adjust the temperature, fan speed, and more with the touch of a button.
Ductless HVAC systems offer numerous benefits. They are easy to install, operate quietly, and offer an attractive design. Ductless systems are reliable, able to heat and cool with the same system, and are controlled wirelessly. A ductless system is ideal for new additions, renovated spaces, and garage or basement rooms, and it’s an effective solution for any property that can’t accommodate ductwork.
Indoor units can be installed anywhere in the room — on the ceiling, walls, or even on the floor. Outdoor units come in a wide variety of capacities, are easy to install, and can be camouflaged — which is especially significant for maintaining the aesthetic of historic homes.
