My wife and I recently hired Galaxy to replace our aging gas furnace and AC with a new 4-ton…read moreMitsubishi heat pump system, and the entire experience was fantastic from start to finish. During the estimate phase, Constantine was a breath of fresh air. Instead of pushing generic upsells, he actually "downsold" us by engineering exactly what we needed to work seamlessly with our home's downflow ducting. He was honest, straightforward, and clearly explained the system without any high-pressure sales tactics. For the installation, Mike and Diego were our crew. They arrived a little past the initial 9am window on the first day, but they worked incredibly hard and got the entire complex job done right on schedule. At the start of Day 1, I handed them a simple "homeowner's QA" list of things I wanted to check with them at the end. They were super nice, listened, and gladly accommodated every single request. The workmanship is top-notch. They perfectly sealed the exterior wall where the lineset exits, helped me get the Kumo Cloud Wi-Fi connected to my phone, and hauled away all the old debris, leaving the site spotless. As a testament to their technical skill, when I asked about the refrigerant line vacuum test, they had pulled it down to 350 microns--which is a great number and proves they don't cut corners! Pics attached of the final setup. If you want an HVAC company that is honest in the office and expert in the field, we highly recommend the Galaxy team!

Just moved to San Ramon and the AC in our new house was not working. Called Chill and they were…read moresuper responsive. They came out the same day and looked over the system. There were a lot of issues. It looked like whoever installed or serviced the unit didn't know what they were doing. Chill offered to repair the unit, including recharging the system, but I was concerned that it would just be a waste of money since the AC would probably fail again soon. Chill then provided a couple of reasonable estimates to replace the AC and explained the pluses/minuses of each option. Decided to go ahead with a replacement. Chill scheduled the installation a couple of days later. They arrived on time and got it done as expected. The lead tech was very friendly and explained everything he found with the old system and what he was doing with the new install. Wherever we've lived we like to support local businesses. It was a good choice with Chill.

They were professional, friendly, and clearly very knowledgeable about what they were doing. They also took care to keep things tidy and picked up after themselves each day, which I really appreciated. On top of that, the pricing was competitive compared to other quotes I received. Overall, a great experience and I'm very happy with the results. I'd definitely recommend them to anyone looking for HVAC work.

What an incredible business Ian and his team are running with Mercury Heating and Air. There is a…read morereason Mercury has 5 stars on Yelp. Our furnace recently went down and was not blowing hot air, leaving our house less than 60 degrees inside and getting colder. We called the original installer (not Mercury) of the furnace to take a look and see if he could fix it. Couldn't figure out the problem but said he would replace the motor and pressure switches for $2,000 after looking at the unit a bit. He then told us we should consider installing a heat pump, so we decided to get quotes from several companies to install one. Ian was the only that asked us "do you actually want to replace it?" instead of immediately trying to sell us a new unit. Even just speaking with him over the phone for a few minutes, he showed just how knowledgeable he was and what questions we needed to ask the other sales reps. So I waited for Ian to come by and give us his opinion. Within 20 minutes, Ian had CORRECTLY diagnosed the problem and had our furnace back up and running for the first time in over a week. He then showed us everything that was wrong with the original installation of the unit. Ian is so incredibly knowledgeable about every single aspect of these units: the thermostats, motors, electrical, filters, fuses, wiring, troubleshooting, everything. He also gave us a quote for the install of a new heat pump and the pricing was incredibly competitive compared to all the other big names in the area. I will NEVER call any one else to get my HVAC serviced ever again. Ian and his team have our business for life and we couldn't be any more grateful.

Last few years, the ac would sometimes turn on and going into this year, I didn't want to worry. I booked Smart on-line and it was really easy. Michael came by and he checked the current setup and explained what needed to be done to replace the unit. He was extremely knowledgeable and answered all my questions. Granted this was my 4th quote so I knew somethings. He never pressured me to purchase but i decided to pull the trigger to have him do the job. The rate was competitive but it was his knowledge and being personable that I made me feel comfortable to have him do the job. The replacement happened the following week and his team took all day. Michael went above and beyond making sure the job was done right and replaced a wood piece to my attic that he didn't need to do, but he did. Very nice. I talked to Susie at the office and she made sure I was aware of the next steps for the HERS test and city permit visit. She was personalable and said to call her or Michael with any questions.
