    Our hvac decided to give out right before another heat wave, and a year after our warranty…read moreexpired... of course. My husband and I evaluated three vendors around the area in great detail and despite Chill coming out slightly more expensive than others, we felt they were the most thorough and comprehensive during the consultation (and the many follow-up questions I had). They were also able to squeeze us into their busy schedule so we could get AC before the heat wave! During installation, they ran into several challenges with placement of the new unit and some wiring that needed more attention. They worked through and around them to make everything work out in the end. I really appreciate their flexibility and expertise to navigate all the roadblocks without changing the scope of work. TIP: Measure the space where the unit is going to be placed and make sure the new unit will fit OR that you discuss this before the project starts.

    Chill is a classic example of the type of business you should avoid. A repair guy (named Vik) came…read moreby to look at my AC system. He said the problem was the starter and said he could fix it for $460. While he was fixing it, I looked up the price of the part. It was $25. He was here for only 15 minutes. After the repairs, I asked him how much of the $460 was for parts and how much was for labor. He said about 50% for each. I then let him know that I found the part for $25. He responded that he doesn't buy the parts himself. So I paid $25 for parts and $435 for 15 minutes of work. Yes, I wish I had gone with another company.

Both Azamat and Elmar were respectful, honest, professional, and hardworking throughout the entire project. They worked efficiently, kept the disruption to a minimum, and made sure the installation was completed properly and with great attention to detail. I was especially impressed with their customer service. The following day, Azamat stopped by specifically to help us get our water heater back up and running, since we were unfamiliar with its operation and didn't know how to ignite it. We really appreciated that he took the time to come back and help us, even though it was a simple follow-up. Overall, the quality of their work and the level of service made us feel that the project was absolutely worth the money. We really appreciate the work Azamat and Elmar did and would be happy to recommend them.

The installation process was super smooth, Eugene was very knowledgeable and explained the details and where the lines would be run. When the outdoor unit location was more difficult to install than expected, Eugene was happy to move the location and try to make it work. Everything was super smooth, Eugene was very punctual and detailed, the installation itself was very clean and precise, and his team left the place spotless and patched up areas so nicely. I am very impressed with his skills and attention to detail and would definitely use Fuse again for service in the future!

Cody was prompt, professional, and thoughtful when considering where to install the vent and we are very happy with our purchase and experience with the QuietCool Guys. If you are considering a WHF, I would highly recommend going with the QuietCool Guys. I ended up with a better product than the other bids and the installation took less than an hour because we already had electrical outlets near where our WHF was installed.

    The QuietCool Guys installed a new Whole House Fan in my Lafayette home today (I called them two…read moredays prior!!). They arrived on time, completed the work in under two hours, and explained everything about my new exhaust fan to me. They were very professional, covered a very large area around where the work took place with plastic, and cleaned up nicely afterwards. It was like they were not even there. The ceiling vent is almost invisible!! Very nice installation. The wireless remote they provided with the fan is very nice too!! It can be wall mounted or just placed on a countertop or railing or desk (very mobile) and it is very easy to use. The fan has a Lifetime Warranty and appeared to be very high quality. It performed exactly how they said it would. The scheduling and communication was excellent!!! Drew was very responsive. The pricing was very competitive too. I am looking forward to big savings on my electric bill, as I have been running my A/C at night to cool down my bedroom so I can sleep well!! I highly recommend The QuietCool Guys for purchasing and installing a whole house fan. Such a great product and install!!!

What I appreciated most was that he didn't just start replacing parts. He thoroughly diagnosed the system, explained what he was testing, and walked me through the results. He showed me that the capacitor was testing low, the contactor was worn and pitted, and even performed a megger test on the compressor to verify it was still healthy. After the repairs, he confirmed everything was working properly by showing me the compressor amperage had dropped back to normal and that the system had an 18-degree temperature split. Keon was patient with all of my questions and never made me feel rushed. He explained the pros and cons of the recommended repairs, including the hard-start kit, so I could make an informed decision instead of feeling pressured. I really appreciated his transparency and professionalism. By the time he was done, our AC was cooling properly again, and he even worked with us on the final price. If you're looking for an HVAC technician who is knowledgeable, honest, thorough, and takes the time to educate his customers, I highly recommend Keon Garcia. Thanks again for getting our family cool again!
