Our consultant, Edson, was professional and knowledgeable. He helped us weigh our options for our AC needs, and we'd be happy to work with him again.

Matthew was very friendly, knowledgeable and I loved that he asked if we were familiar with the product. He also went so far to ask what our vision for the product was before he gave us our option. He didn't force his design on us like people has done before on other projects. I would recommend

5-Star Review: Dr. Ductless is Outstanding — We’re SO Happy! We just finished a full Mitsubishi MXZ-5D42NL multi-zone heat pump installation (3 cassettes + forced-air handler with 8 line sets) and are very pleased. This system is super quiet and effective — the best AC and heating all in one. From day one, owner Matthew Alba was professional, respectful, kind, and truly attentive. He listened carefully to our particular needs and desires, then guided us to the perfect system and setup for our home. His expertise and care made the whole decision process easy and enjoyable. Lead foreman Angel (and the entire installation crew) were fantastic. Angel is extremely professional, knowledgeable, kind, and hardworking. The rest of the team was amazingly skilled, worked together like a well-oiled machine, and made the job run smoothly and efficiently. They were all a pleasure to have around — we actually looked forward to seeing them each day. A huge shout-out to Karina and the rest of the office staff too. They were totally on the ball — checking in often, answering every question, and providing all the information we needed. Their coordination made the entire project seamless from start to finish. Dr. Ductless truly shines. We’re very happy with the quality of work, the attention to detail, and the way they treated us like family. We will always use them from now on for any AC or heating needs. If you’re looking for a trustworthy, top-tier HVAC company, look no further — these folks are the real deal. Thank you, Matthew, Angel, Karina, and the whole team!

Matthew was very knowledgeable and informative! It was a consultation…not a completed project.
