Frequently Asked Questions About Ductless Mini-Split Cooling Services in the DMV

What is the cost to install a new ductless mini-split system?

Most installations range from $4,000–$12,000, depending on system size, efficiency, and home layout. We offer a full assessment for an accurate quote.

Should I repair or replace my ductless mini-split?

Replacement is usually best if repairs exceed 40–50% of a new system’s cost or your unit is older than 12–15 years.

Are ductless mini-splits more efficient?

Yes. They deliver cooling directly to each room, avoid duct losses, and let you control only the spaces you use, which saves energy and lowers your bills.

Why isn’t my mini-split cooling properly?

Common causes include dirty filters, low refrigerant, frozen coils, or a malfunctioning compressor, all of which a technician can fix.

Do you provide ductless services for outbuildings and additions?

Yes. We install and service ductless mini-split systems in garages, workshops, barns, and other home additions to keep every space comfortable.
