HVAC reviews in San Ramon, California

A great company for repairing our central AC unit. Calderon and Marion came over, investigated the problem, worked very hard, and fixed the problem. Our AC is now working better than ever. Thank you.
Calderon and Marion were friendly and very professional. Eco System Heating and AC is now my go to company for heating and AC issues.

Abraham and his tech were prompt/on time, professional, knowledgeable and courteous. The front office was also impressive with the scheduling and communication. I am Realtor and have worked with a LOT of HVAC companies and these are were so good I am going to have them service my own home. A top notch experience!!

Super fast service. Calderon and Ivan were very friendly knowledgable, and quick. Were able to get me in earlier than planned. Will use them again

Chldeion was amazing, he was very informative, quick to answer any questions and was very knowledgeable. He worked extremely fast, and cleaned up like he was never here. I would recommend him to everyone, and will only call for him in the future.

Carlos and Calderón were the technicians who handled the installation, and they did an outstanding job. Fast, professional, and very detail-oriented. The system was installed in our company’s server room at RobinsonHSS with zero disruptions. Highly recommended
thank you for the excellent service!

Calderon and Ivan did a great job installing our new furnace. They were professional and efficient. Happy to have a warm home again all thanks to them.

Ivan and Calderon came by and fixed our air conditioner which had been broken for 3 months and visited by several other companies. They spent a long time working on it, the set up looks much nicer. We are thankful that both our heater and air conditioner are working smoothly!

Calderon and Ivan were both extremely polite and efficient. They did an inspection on my current heater/furnace and were very thorough. I appreciate them explaining everything to me and making the experience pleasant.

It was my first time and I had a terrific experience with Kevin. My fridge stopped cooling overnight and he promptly came over the same day.

I appreciated his transparency by going through every detail and strategized and on the best way forward. The fridge unexpectedly had other unexpected failures and had to take longer but Kevin stayed, came back over 2 days to make sure everything is working properly.

Consider me a repeat customer.

Great response time, Andy was very helpful in explaining the issue. Very good price. Will definitely be calling them with any needs in the future.

Our refrigerator had a water leak after we installed brand new floors. I called and Zoe was able to schedule Andrew for an appointment in next 1hr. Andrew did an amazing job quickly identifying that cause and replaced the faulty part and cleared up the drains. We have a warranty for next 6 months but I am hoping we wont need that.

My 20 year GE Monogram built in fridge is running like new!! My fridge was running too cold when I called Chill HVAC. Sam came out the same day. He was professional, knowledgeable and quickly diagnosed the problem. He ordered the parts and returned a few days later to fix our fridge. He replaced a broken part, performed a cleaning and changed the compressor! He was thorough and efficient. I highly recommend this company to service your refrigerator!! I will definitely keep Chill HVAC in mind for any future repairs.

I highly recommend this company. Super honest and really easy to work with. They were punctual, professional and fixed my AC issue immediately. Awesome service!!!

I just called last night because my hvac wasn’t working during the weekend. While all other service providers aren’t available in the weekend, Chill came just the morning next day with prompt response. Very happy with the service and I highly recommended!

I invited Victor to maintain my household appliances. And despite the holidays - Victor came and did everything at the highest level. I am very grateful to this company for the excellent service!

These guys were great. Responsive, fast, professional, and reasonable on price. Would highly recommend. Fixed our Whirlpool fridge and 6 months later fixed our Carrier AC system.

I was so impressed with the service from Chill Heating. Andy showed up within an hour of my call, diagnosed the issue quickly, and had our AC back up and running by replacing a key part and refilling the freon. This was a lifesaver in the middle of summer, and I'm very grateful for his fast, expert work

Alex, right on time and provide us the accurate and professional service regards to our refrigerator. We appreciate your service and recommendation.

Kevin and Sam from Chill were incredibly responsive and helpful in evaluating and replacing my AC and furnace systems. Trustworthy and professional crew.

Update: Jack came over to check our Carrier furnace when it stopped working this fall. They did a quick review and figured out that the recent earthquakes tripped the emergency gas fail safe. Everything is working perfectly again.

Chill recently installed an AC unit for us. From the time of initial inspection to getting the work done, Chill were very professional and knowledgeable. I interacted with three members from their team throughout this process and all three were great to work with. They arrived on time on the day of installation, finished their work on time as well, cleaned up and left our house in the same condition as before. The job they did is very neat. I would highly recommend them and would hire them again in the future.

Use at your own risk. I know they have a lot of positive reviews but they scammed and deceived me by unplugging the temp sensor in my refrigerator and then quoting me $700 for a motherboard replacement.

Also, they are the same company as Techno HVAC, so avoid them too!

Beware!
