read our hvac faqSDuctless systems are increasingly popular in Tacoma and Seattle homes due to their efficiency and ease of installation.
A single-zone mini-split typically costs between $3,000 and $7,500, while multi-zone systems range from $7,000 to $18,000. The final price depends on the number of indoor units needed and whether electrical upgrades are required.
Mini-splits offer zoned comfort, high energy efficiency, and do not require expensive ductwork modifications. They are often a good solution for older homes like in Tacoma's Old Town, room additions, finished basements, and other spaces where extending ducts is not practical.
Common causes include dirty filters, poor home insulation, or a system that was incorrectly sized for the room. While mini-splits are generally very efficient, they must be maintained properly—especially the indoor filters—to keep operating costs low.
With annual professional maintenance, a high-quality ductless system typically lasts 12 to 20 years. Because the outdoor unit works year-round for both heating and cooling, regular cleaning and maintenance are especially important.
Yes, mini-splits are "heat pumps," meaning they move heat into the house in the winter and out of the house in the summer. They provide some of the most consistent and comfortable cooling available, which is perfect for our increasingly warm Western Washington summers.
Professional installation is strongly recommended to ensure the refrigerant lines are sealed correctly and the electrical work meets Washington State code. A DIY installation often voids the manufacturer's warranty and can lead to expensive leaks that are difficult to fix later.
Yes. Many older homes in Tacoma and Seattle were built without central duct systems. Ductless mini-splits provide heating and cooling without invasive remodeling, making them practical option for historic homes, finished basements, and room additions.
