What customers say
"I was very impressed with John and the man that was with him. I was really surprised at all the things they did to check my heat pump and ac. I felt comfortable having the Run Compastor (not sure if this is spelled right) replaced. I feel like my heat pump and ac will be fine. I think better things were done than ever before and I sincerely hope this is new for your company."
— Joyce Leo · Nov 5, 2025 · Google Reviews"A great install by Way Cool! Eric came out after the City of Scottsdale contacted me regarding excessive water usage. It was determined there was a leak under the sidewalk near my front door in the main line from the street. An 18” deep trench had to be dug from the street after new yard had just grown in. Every effort was made to protect the yard. Eric and Vinny did a great job and left the site clean."
— Alyce Michaud · Oct 29, 2025 · Google Reviews"Zach Herrara did an excellent job checking out my heating system and airflow. He discussed the pros and cons of changing to a 3 in air filter. Discussed maintenance plan."
— Raymond Yelle · Nov 4, 2025 · Google Reviews"Jeff was very kind and courteous. He was to the point about the many things I need done and helped me to prioritize them. He was very good at explaining the reasons things need doing. I am a very inquisitive about the why and he was able to answer my questions in a logical, easy to understand way. Thank you for spending the time with me. I'll be chipping away at these projects as I am able to."
