Whether you’re upgrading a single room, adding climate zoning, or improving energy efficiency across your home, we provide expert installation, repair, and maintenance for ductless systems throughout Western Washington.

Our team of licensed HVAC professionals designs mini-split solutions that fit your home’s unique layout, comfort goals, and budget—because every space deserves personalized comfort that lasts.

Why Choose a Mini-Split System

Mini-split (ductless) systems are one of the most efficient and versatile ways to heat and cool your home. They provide targeted temperature control without the need for ductwork, making them ideal for room additions, older homes, or spaces where central air isn’t practical.

Benefits of a mini-split system:

  • Energy Efficiency: Eliminate duct losses and reduce monthly energy bills.

  • Zoned Comfort: Set different temperatures in each room for customized comfort.

  • Quiet Operation: Advanced inverter technology provides whisper-quiet performance.

  • Year-Round Use: Many models offer both heating and cooling in one compact unit.

  • Improved Air Quality: Built-in filtration reduces dust, allergens, and humidity.

  • Compact & Discreet: Sleek wall-mounted or ceiling-cassette options fit almost any décor.

For homeowners who want comfort without compromise, a ductless mini-split is one of the smartest investments you can make.

Two HVAC technicians are installing an air conditioning unit in a home.

I had an incredible experience with the team from Infinity! They came to my salon to handle our HVAC needs, and I was blown away by their professionalism and efficiency. The entire team was amazing—friendly, knowledgeable, and respectful of our space. They completed the job super fast without cutting any corners, and everything works perfectly now. I truly appreciate their attention to detail and commitment to quality. If you need HVAC work done, I highly recommend them—you won’t be disappointed!

Infinity Heating & Air was fantastic! Would give 10 stars if I could! They recently replaced our Heating/cooling system, and were skilled, professional, and so kind! The whole team went above and beyond. They truly focus on customer service and I would recommend them time and time again! Thank you!!

Jessica Y.

Wow! If it was possible to put 10 stars, I would! Most excellent customer service, easy scheduling, and wonderful to work with. The installers were clean and courteous. The owner stayed late to make sure we were up and running as well. Would highly recommend to all my friends and family. Wonderful to be able to support a family owned local business!

Christina L.

Absolutely the best! Ken is fantastic and his crew is so nice. Did a great job 3 years ago installing my new furnace and ac unit. Love it! Even after all this time he remembers me and my situation. That means the world! These guys at 10 stars if I could rate it. If you need a furnace or anything HVAC, look no further. I promise, good prices and the quality and reliability of maintenance is beyond expectations!

Eric M.

I had a fantastic experience with RJ Montgomery , Ken Brasmer, and the rest of the team who installed our new AC unit. They were incredibly professional, punctual, and efficient. The installation was completed quickly and with no mess left behind, leaving our home in excellent condition. The level of service they provided was truly exceptional and hard to come by elsewhere. I also want to extend my gratitude to Heather, the secretary, who was responsive and attentive to our specific needs. This team is top-notch and I will definitely be recommending them to all my friends. Thank you again for a job well done!

Natalia M.

We had two other companies come out to look at our heat pump and suggest some parts to replace. I replaced them myself and was able to diagnose the real problem, which was beyond my abilities to fix. I called infinity and they were able to come up with a simpler solution over the phone, come out in a couple days and fix it quickly, and charged what they had quoted on the phone. They will definitely be my first call the next time I have a problem.

Erik O.

Ken and his team were took care of replacing an old furnace and installing a new heat pump. Were they the cheapest, no. But they were very responsive to all my questions and schedule. RJ installed was the team lead, and made sure all of my questions were answered. RJ noticed a small detail, and made sure it was corrected before being satisfied with their work. I would highly recommend this company, when they talk, they keep it real. I left feeling like I was more than just a customer.
