Zevin was on time and professional. Explained things without pressure. We have an older system so Zevin discussed options going forward.

I've been using Cool Willy's for a number of years for semi-annual maintenance and have always found them to be excellent. My two units are over 20 years old, and they've been warning me that various parts are close to failure. A month ago, their tech (I wish I had his name) came to me with a laundry list of problems that required fixing. After a long discussion that included his manager, I decided to put in new systems. The cost wasn't that much higher than all the current problems. Two days later, Noah, Ramon, Matt, and Kevin showed up and installed both units in one day. They were professional, friendly, and very careful about keeping doors closed so my cats couldn't escape, LOL. When they were done, they cleaned everything up, including taking some junk in my back yard that had nothing to do with the HVAC systems. Two weeks later, the unit that cools my bedroom stopped cooling. I called them, and they promised to send someone that day to repair it. I expect problems to arise, but I also then expect people to be responsive. I couldn't ask for a better response. This is a first-class outfit. Oct 2026: The AC on one side of the house was barely working, so I called and Noah (again) came by the next day. He quickly found the problem and fixed it. During our discussions, I mentioned some plumbing issues and he called and had a plumber out here within a couple of days. From the folks who answer the phone to the people coming to the house, this remains an exceptional company.

John and Lizzy were amazing! Lizzy made the scheduling process smooth and accommodated all of my requests. John came out and found the issue within 10 minutes. He’s a plumber who was even able to identify the source of a roofing-related problem, which pleasantly surprised us. They were both professional, responsive, and incredibly helpful. Highly recommend!

I’m very happy that John King from Cool Willys installed my new water heater. He did an excellent job very quickly. I’m going to have them do yearly maintenance to keep the water heater in good condition.

Zevin & John both did a great job. They explained everything they did & both men were very respectful. It was recommended I purchase an air purifier that self cleans. It was also recommended last year when I had my heater serviced for $900.00 which I declined. This year the purchase was $1400.00 which is quite a rate hike.

Joe provided excellent customer service throughout the entire process. He clearly explained the diagnostic process, answered all of my questions, and demonstrated genuine concern for my situation. He also provided a detailed explanation of how to improve my system and the reasons behind his recommendations. I highly recommend Joe and Cool Willy’s for any air-conditioning concerns or service needs.
