Bartol was punctual, efficient and thorough in providing their services, from obtaining the original estimate to installation. They had to work around the weather and scheduled the exterior and interior portions of the job accordingly, instead of simply delaying the entire job. Bartol and their subcontractors were knowledgeable and amicable to answering any and all questions I had, making me feel as comfortable as possible throughout the process. In addition, the quality of the equipment used is excellent and their prices are reasonable; They even provided a follow-up service gratis to fine tune the system and correct some minor operational issues. Overall, it was a great experience and I would absolutely recommend them to anyone looking for Central A/C installation and service.
