2/24/26 update: If your capacitor needs replacement and it's the regular kind... think twice about Dayco. I have learned that if you have to replace your capacitor... Dayco doesn't even offer the option of replacing your regular common kind of capacitor... you have to upgrade to a turbo capacitor... a $500 to $600…

In August the hottest month of the year on a Friday afternoon our AC goes out. They were to us within an hour. Cleaned it completely and fixed it. I felt bad because he worked so hard in the heat. He had a very positive attitude and did a great job. Cannot recommend this company enough. They are amazing.!!!
