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.
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.
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.
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.
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!
