Since changing out or system our pg&e has gone down significantly! Can’t say enough good things about Cozy Comditions!

AC went out in our home during a heat wave. Went on an FB group for recommendations on AC techs and the community mentioned Cozy Conditions a few times. Called Will and was greeted warmly on the phone and, lucky us, he had availability to come the same day. Will’s communication before, during and after our service was great. He took the time to explain everything and got us up and running shortly after. Would definitely recommend and glad to have him as a contact for any future HVAC needs.
Hazel, thank you for having me out today. I was glad that I was able to help you guys out. Thank you very much for the kind words. Don’t hesitate to reach out if you guys have any questions. Have a good day
Will is the marquee professional through & through. He was extremely informative with tips & tricks. Made sure to accommodate my schedule and as a bonus a great person to chat with. Would 10/10 recommend this service for ALL

Thank you Jeremiah will always appreciate five star stars.
We had a great experience with Cozy Conditions. Will, the owner, was prompt, professional, and communicated clearly with us throughout the entire process. He showed up on time, explained everything in a way that was easy to understand, and made sure all our questions were answered regarding the replacement of our furnace and a/c. . The pricing was fair, especially considering the quality of the work and level of service provided. It’s not always easy to find someone reliable in this field, but this was definitely a positive experience from start to finish. We’re very pleased with the service and wouldn’t hesitate to recommend Cozy Conditions to anyone looking for honest, dependable HVAC work. Thanks Will!f

Hi Jenny, thank you very much for the review. We appreciate your business and hope you’re enjoying your high-efficiency gas furnace from Bryant. Let us know if there’s anything else we can help you with.
We had a great experience with Cozy Conditions HVAC. The owner, Will, was knowledgeable and transparent throughout the entire process, which made a potentially stressful situation much easier to navigate. He clearly explained the issue with our freon leak and walked us through multiple options to fix it without any pressure. After considering everything, we decided to replace our system, and I’m glad we did. The installation was completed within the exact timeframe he estimated, and everything went smoothly from start to finish. In addition, the cost was very competitive compared to other quotes that we received from local contractors. Will communicated well throughout the process and was always friendly and personable. Our home was left clean and tidy at the end of each work day and now it is cold and comfortable too. If you made it this far, hire him! Thank you Will!
Kaycee my family and I thank you for your business, and the kind review. Enjoy your new Bryant air-conditioning system and let us know if there’s anything else we can do for you in the future.Thanks
So thankful I was able to connect with this company to handle my furnace repair. I found them on Nextdoor app and from the start in all our conversations Will was very professional, prompt, and courteous. He explains everything before hand. It was a gas valve repair. The pricing came in at a very fair price for my budget. So lucky to have found him. I recommend Cozy Conditions for all service and repair needs, Grateful for him to have come out and got me up and running in this cold cold weather.
Thank you, Michelle for your business. We’re glad to hear that your furnace is up and running safely and look forward to serving you in the future.
