HVAC reviews in San Ramon, California

Technician (name: Slava) showed up at the right time and he was very professional. He explained me very clearly what might be the problem with my refrigerator.

Another problem was the original installation of the my refrigerator. Technician warned me that since the cabinets were too narrow / tight for the equipment, it might not be possible to insert the refrigerator back into it's location again. Because of this problem we decided not to remove the fridge yet. First, I will need the fix the problem with the cabinets.

This is a great company for HVAC systems. The guys came a day earlier and did everything in one day. They were professional, made sure to keep everything clean, and did a great job. Thank you for the hard work.

Chill Heating and Cooling has earned a customer for life! I will definitely be using them for all my future HVAC needs and recommending them to everyone I know. Here is why: easy to setup an appointment online, very prompt customer service, professional and friendly techs, fair pricing and great overall service and housekeeping. They installed new Carrier AC in one day.
So, if you're looking for reliable, honest, and expert service, look no further. Truly five-star service!

Very good service! One day full HVAC system replacement, friendly and polite technicians!
Will recommend this company to my neighbors and relatives!

Chill recently came to my house to fix an old, 1950s era, furnace. Before they arrived I was thinking their solution was going to be replace the unit, I.e. upscale. Alex, the tech, evaluated the system and said there were only a couple of things that could be wrong and fixed the system by simply replacing the thermostat. I appreciated the honesty and integrity. I would recommend Chill to anyone needs heating and AC service. Thanks.

I would give 0 stars if allowed but not for their service but their customer service.
Once the service was completed they called incessantly to be paid. They called an left 3 messages within less than an hour. I was out shopping for the holidays and then my phone died. They also called my tenant where the service was done multiple times as well. I understand wanting to get paid after a service is done but this was extreme! A total of 10 phone calls in the space of a few hours!
I also found it strange that they will only receive the service deposit via credit card then telling you they will charge 3% to use your credit card. I don't have a problem as they are charged by the credit card companies but when I pressed they said I could pay by Zelle. This should be an option offered

These guys were amazing, responded immediately on a Sunday and came out the next day. Great communication, showed up on time / early. Turns out my “repair” was a very minor thing so did not even charge me for it. Very courteous and professional, I highly recommend them. Great company and people.

I recently had a mini split system installed by Chill Heating and Cooling, and I couldn't be happier with the service! From the initial consultation to the final installation, the team (Slava) was professional, knowledgeable, and efficient. They took the time to explain my options, helped me choose the right system for my needs, and completed the job with precision.

The installation was done neatly, with no mess left behind, and the system is running perfectly. My home is now much more comfortable, and I’m already seeing the energy savings. I highly recommend Chill Heating and Cooling to anyone looking for a high-quality mini split installation!

Thank you for the excellent work!

We had an excellent experience with Chill. Kevin, Slava, Alex, and Jack were all so informative, helpful, kind, and a pleasure to work with. Even running into a snag from the distributor, they went out of their way to make our home warm for the holidays. They helped us navigate the best system for our needs today and for the future, based on a thorough assessment of our home size/layout and budget. The quality of work is great, communication was clear and concise, and they worked with our budget. I’d recommend them to anyone!

Alex from Chill Heating and Cooling delivered outstanding service from start to finish. He arrived right on time, quickly diagnosed the issue with my system, and explained everything clearly so I knew exactly what to expect. His professionalism, knowledge, and attention to detail were truly impressive.

What stood out most was how genuinely committed he was to making sure the job was done right. He worked efficiently, kept the workspace clean, and went above and beyond to ensure the system was running perfectly before he left. It’s rare to find someone who combines skill, honesty, and customer care so well.

I highly recommend Alex to anyone needing heating or cooling services—he’s reliable, knowledgeable, and an absolute pleasure to work with. Chill Heating and Cooling is lucky to have him!

Also want to add that the company’s receptionist was polite and efficient accommodating us into the schedule for the same day. So the issue was resolved the same day!

Jack and Alex installed a heater and ac unit. A two day job took one day. Chill Heating and Cooling were very professional, organized, and efficient. I have not had any issues with the work they have done. I ordered carrier products and they were nice enough to upgrade some of the products as an added bonus. Thank you Jack and Alex.

Back in October, my older Nest thermostat started going offline because Google no longer fully supports that generation in the Google Home app. It was frustrating to lose remote access and control. I knew it was an older model, but I didn’t realize it could cause partial failures like this. My furnace would cycle on and off erratically, leaving the house cold despite the thermostat seeming to work partially.
I tried watching youtube videos and cleaning some components myself, but after a week with no improvement, I called Chill Service. Igor came out the same evening—super responsive! He inspected my furnace in about 20 minutes and pinpointed the issue: the malfunctioning thermostat. I was skeptical at first because light were on and it was starting the furnace, but once he replaced it with a new Google Nest thermostat (4th gen), everything heated perfectly again.
He also installed a Nest temperature sensor in our bedroom (the coldest room in the house), and we’ve noticed a real difference—the room feels noticeably warmer and more comfortable at night now.
This is my second time using Chill, and I can’t recommend them enough. They’re fast, friendly, knowledgeable, and genuinely kind. If you need HVAC help in the area, go with Chill—no hesitation!

I had an excellent experience with Chill Service! Our heating system wasn’t blowing warm air, and the technician arrived right on time, quickly identified the problem, and explained everything clearly. He found a refrigerant leak and gave us a detailed plan for repair and refill. The work was done efficiently, and now the system works perfectly again.

I tried to install a smart thermostat on my own but the procedure was a bit more complicated than I thought. Alex came on time and was incredibly fast. He was able to identify the issue and install it in a breeze! I will definitely call on Chill Heating and Cooling again and hope to use them for a bigger project for replacing my HVAC system in the house.

These folks were quick to set up an appointment for a quote, installed a new split HVAC system the next week, and the job took one day total. Very professional staff and installers, especially Alex who wanted to go above and beyond to make sure (in his words) "everything is perfect" when the job was done. The install was very clean on the inside and outside of the house, see the pictures. I will definitely call these guys again when I have an HVAC need.

We had a great experience working with Chill Heating and Cooling to replace the HVAC system in our house.

Our old HVAC system was a Carrier Infinity system with multiple zones, so the setup was fairly complex and not something every contractor fully understands. We got several quotes, but Chill stood out because they clearly understood the existing system, the zoning constraints, and the realities of our house. Their recommendation was the most technically sound given those constraints, rather than just proposing a generic replacement.

They were quick to schedule, showed up on time, and were professional throughout the installation. The install itself went smoothly, and they were careful and organized during the process.

The new Carrier Infinity system has been working really well. It’s very quiet, heats our house evenly, and maintains the precise temperatures we set across the different zones.

We’re very happy with the outcome and would recommend Chill Heating and Cooling, especially if you have a more complex or zoned HVAC setup.
