I decided to replace my central air system with mini-split in each room. It’s a true pleasure working with James from Lunar Air Systems on my project. I can confidently say that he is the best HVAC technician I’ve encountered. It’s hard to find someone who is truly passionate about their craft. James is a rare professional who goes above and beyond. From the very beginning, it was clear that James takes great pride in his work. He dedicated ample time upfront and made himself available whenever needed to discuss all possible options for resolving my heating and cooling issues. Unlike other quotes that I got with guesstimate sizing for my house, James carefully inspected my house with multiple visits and produced a formal load calculation report to help me understand what my house truly ne

I recently had the pleasure of working with Lunar Air Systems, and I can’t say enough good things about James. His work ethic is outstanding. James checked every detail while repairing my air conditioning and heating systems. He meticulously tested the entire pipeline and air conditioning unit with his instruments before fixing the evaporator, ensuring that all other components were functioning correctly. During the repair process, James discovered a crack in my heat exchanger. His thoroughness in every aspect of his work is truly commendable; it’s this attention to detail that allowed him to identify the issue with the heating system while fixing the air conditioning. Although I ended up spending more money to repair the heating system as well, I am incredibly grateful for his keen eye a

Our HVAC furnace blower fan won't stop even the thermostats are off. After several self inspection, it turned out the issue is so complex that I have to call HVAC technician. The reason we hire Lunar Air are: 1. James is working 24/7, and jump in to a call right away before he visit for diagnosis. 2. His inspection and diagnosis are so detailed that itself worth price just for knowing where the issue is. Debugging is much harder than solving it. 3. James is amazing person if you like to learn about HVAC system, since he could always provide info on "ideal system" v.s. "temporary fix", which I appreciate. 4. Very transparent on pricing, cost of parts ...etc. Turn out his service is totally fair given how much work/time he put in. 5. Lunar Air is 10 mins away from my house, James show up qu

Don’t need to look any further for your HVAC needs. James is the real deal! He is extremely knowledgeable and will provide you the best service. I had the pleasure working with him for an entire furnace replacement to an electric heat pump in attic, and couldn’t be happier with the outcome. Doesn’t matter if it’s small or large projects, he is super passionate about his craft and really wants to do a good job.

The owner, James, responded immediately on a busy holiday weekend to help us fix our air conditioning unit. He offered over the phone trouble shooting before coming over the same day to repair our unit. Incredible customer service!
