“⭐️⭐️⭐️⭐️⭐️
We had a fantastic experience with Aldo, our service technician. After another company told us our furnace was beyond repair and needed to be replaced, Aldo came in, took a thorough look, and discovered the issue was simply a blown fuse. He replaced it quickly and had our furnace running in no time—saving us thousands of dollars.

What really stood out was Aldo’s professionalism and transparency. He took the time to explain everything clearly, walking us through what had gone wrong and how he fixed it. His honesty and attention to detail were incredibly reassuring. It’s rare to find someone so knowledgeable and genuinely committed to helping customers.

Highly recommend Aldo for anyone looking for trustworthy, top-notch service.

“I have a wonderful history with this company since initially using them for a complete renovation ten years ago. Since that time, they have continued to perform at the highest level of quality professional service. They operate more as a family than a business and their attitude is reflected in every technician they employ. And, they always seem to go above and beyond whether it’s a routine scheduled maintenance or an emergency.
Highly recommended without reservation.”

“Aldo and Israel were fantastic in leading a team to get our old AC unit out and a new one in. Courteous, efficient and completed in one day. Most grateful to them and the entire staff at Cool Sunshine”

- Neil S.

“Another Company had inspected my ac unit shortly before Israel took a look at it and recommended a new evaporator coil, compressor, and motor-blower; however, Israel was able to provide clear guidance that my system was not experiencing any issues and would continue to work just fine with some minor cleaning and repairs. His advice saved me thousands. I will be a Cool Sunshine and Israel advocate and customer for life.”

- Grant R.

“We've been working with Cool Sunshine since 2009. Service has been impeccable, specifically working with Israel. He defines professionalism, care, impeccable work, work ethic and integrity. I learn something every time he comes, which ensures confidence that our system is consistently running smoothly. Israel approaches every service as if it were maintenance on his own home. Cool Sunshine says it's dedicated to building lifelong relationships, and with employees like Israel you have our commitment. Thank you to Israel and cool Sunshine.”

- Stephanie M.

Excellent experience. I felt that the technicians were professional, efficient, and courteous.

- Dennis K.

“Cool Sunshine installed and has maintained our heating and cooling systems for over ten years. The owners are extremely knowledgeable, and you know they are good at running their business when the "new guy" has been there for 9 years and staff are not just good at what they do, but love what they do. Can't say enough good things. Just, thank you.”
