Thank you to NWX for the quick and efficient service. They had a technician out to my house for my no heat the same day AND had my furnace installed by 10am the next morning. KUDOS to the office staff, especially Daryl& Zane (who helped me).

Had a great experience! Virgil, our first tech, was able to diagnose issues quickly, provided pictures and explanations, and recommended solutions. Gave a really good "good, better, best" recommendations. Got an immediate follow...

Charles was amazing! He listened to ALL our concerns and had a resolution for each one. My husband and I were so happy with the level of education we received about our system from Charles. ( and of course LOVED the photos of Amelia 🙂

Mike came out and he’s a nice and respectful man and he didn’t mind showing me the process and steps. He went one by one and his trouble shooting was fantastic. He was very systematic and found the problem and solved it. My A/C is now...

I would like to do a shout out to Northwest expert heating and cooling for their superb service Technicians. They are skilled and responsive to your needs. We installed a complete AC and Furnace and they have stood behind the product.

Could a Ductless Mini Split Be the Right Fit for Your Home?

Federal Way’s mix of older homes and newer builds means comfort needs vary from house to house. Many homes here don’t have ductwork running to every room, especially additions, converted garages, or bonus rooms above the garage. A ductless mini split solves that problem by delivering targeted heating and cooling exactly where you need it.

Our marine climate also plays a role. The humidity that rolls in off Puget Sound can make rooms without proper airflow feel muggy and uncomfortable, even when the temperature itself isn’t extreme. Ductless systems help manage that moisture while keeping energy costs down, since you’re only conditioning the space you’re actually using.

Homeowners with multi-family setups, home offices, or finished basements tend to see the biggest benefit. If you’re constantly adjusting a space heater or window unit to get comfortable, it’s worth having one of our technicians take a look at whether ductless makes sense for your layout.

How Our Ductless Mini Split Installation Works

We start with an in-home visit to evaluate your space, discuss your goals, and recommend the right system size and configuration for your needs. Our team walks you through brand options and features so you know exactly what you’re getting before any work begins.

Once you approve the plan, we schedule the installation at a time that works for your household. Our technicians mount the indoor unit, run the necessary line set to the outdoor condenser, and handle the electrical connections with care, since we’re licensed for both HVAC and electrical work. This means fewer subcontractors involved and one team accountable for the whole job.

After installation, we test the system thoroughly to confirm proper airflow, temperature control, and refrigerant levels. We also walk you through how to use your new thermostat or remote so you feel confident operating the system from day one.

What You Gain From a New Ductless Mini Split System

A new ductless mini split gives you room by room control, so you’re not paying to heat or cool spaces that are empty. This kind of zoned comfort tends to lower utility bills compared to running a whole-house system for one occupied room.

These systems also run quietly compared to traditional window units, and installation is far less invasive since there’s no ductwork to tear into walls or ceilings for. That makes ductless a strong option for additions, garage conversions, or older Federal Way homes where adding ducts isn’t practical.

Many homeowners also appreciate the improved air quality that comes with modern ductless systems, since most models include filtration that helps with the pollen and moisture common in our area. Combined with reliable heating and cooling performance, it’s an upgrade that pays off in comfort and long-term savings.
