Questions & Answers

Frequently Asked Questions

Are ductless mini-splits a good choice for Charleston homes?

Yes, for many homes. They work well in additions, bonus rooms, sunrooms, and older homes without ductwork. They also provide both cooling and heating, which suits our mild winters and long, hot summers.

Do mini-splits help with humidity?

Yes. Like any air conditioner, a mini-split removes moisture as it cools, and many models offer a dry mode. In Charleston’s humid climate, that can make a room feel noticeably more comfortable.

How many indoor units do I need?

It depends on how many rooms or zones you want to condition and how your home is laid out. A single room may need just one unit, while a multi-zone system can serve several areas. We will recommend the right setup during a free estimate.

How should I maintain my ductless system?

Clean or rinse the indoor unit filters regularly and keep the outdoor unit clear of leaves and debris. Near the coast, salt air can build up on the outdoor coil, so routine professional maintenance is a smart way to protect efficiency and lifespan.
