I called these guys after work hours and they answered right away, routed to the correct person who contacted me from their personal cell phone. We ended up realizing that I didn’t really need help and they gave me some free advice, very solid business presence and ethics.

Galaxy HVAC installed a mini-split heat pump system in our condo building and did an amazing job. Michael helped several of us owners design a great system and always answered questions within a day. Jose and Alex handled the install — on time every day, walked us through everything, and even tweaked the plan to make the system more hidden, exactly like we wanted. Alex even made some last minute tweaks to our system that really improved the air flow and aesthetics. Kind, trustworthy guys I felt totally comfortable having in my home. The system itself is well designed and the temperature control is fantastic — we couldn't be happier with it. We got three other quotes and Galaxy's was very competitive. Highly recommend, and they'll be my first call for future HVAC needs.

Wow, Servando is amazing. He arrived bright and early at 7:30 in the morning, earlier than usual, at our request. He was very diligent in finding the problem and was able to fix it. What I liked most was his speed, but also the fact that he didn't try to sell us anything we didn't need. He simply adjusted the heating system, and everything is now working perfectly. Thank you so much, Armando, for being such an excellent worker.

As a new landlord of a circa1904 Victorian, I was a bit nervous calling in an HVAC company. I know this industry can take advantage of homeowners who are still learning the ropes, so I did my homework before reaching out to Galaxy HVAC. I'm glad I did, because Zach and the team made the entire experience seamless. My upstairs tenants were dealing with uneven heat distribution, which is par for the course with a home this old, but Zach took the time to walk me through exactly what was going on and what the options were. No upselling, no jargon designed to confuse. Just a straightforward, professional explanation and a very fair price for the work. From scheduling to completion, the service was excellent. This is exactly the kind of company you want in your corner when you own older property. Galaxy has earned a permanent spot on my speed dial for any HVAC needs going forward. Highly recommended, especially for fellow landlords who value transparency and honest work.

Mike came to our house to consult on an HVAC replacement. I was super impressed as: 1) He is extremely friendly, knowledgable, & a clear communicator. 2) He promptly answered our texts and calls. 3) At all points in the process he gave us options (“best in class” & “budget”) & honest advice on what he would do if it was his home. 4) He uses Mitsubishi Diamond Elite, which is top class hardware. 5) His prices were very competitive. 6) He was honest about the differences between himself and our competing offers (good and bad). Very impressed by his style and integrity.

Galaxy Heating & AC recently replaced a split HVAC system in my clients’ San Francisco home, and they were fantastic to work with. After getting a few bids, we chose them for their great pricing and clear expertise—and they didn’t disappoint. Ramiro and Vladimir were our main contacts and made the whole process easy and professional from start to finish. The installation went smoothly, the work looks great, and my clients are thrilled with the outcome. Highly recommend Galaxy and their team!

Eddie was extremely professional from start to finish. He communicated clearly every step of the way, paid close attention to every detail, and made sure the workspace was spotless when he was done. The passion he has reflects in his knowledge and workmanship. He certainly delivered 100% effort to deliver quality results. Eddie was very friendly, as well as professional; he was a pleasure to work with and I look forward to working with him again in the future. I highly recommend Eddie for anyone looking for a skilled and dependable HVAC technician!
