Verified PurchaseDependable and Reliable Company
June 25, 2025
The company A.B. Chelini provided excellent service in providing new HVAC system with air condition. All of concerns and questions were answered and verified. At the completion, the workings were explained to me with satisfactory. My air condition was installed on pedestals which helps because of the location placement of Air condition. Neighbors have inquired about the company. The problems that came up; were resolved in a professional manner; followup was also done. This is mostly unheard of today. I am very pleased with the company.
