“We were very impressed with the expertise and attention to customer needs that OSA provided. Their analysis to identify the most cost-effective equipment to provide AC and heating to our home was outstanding. Their team, from the first consultation to the job completion, was noteworthy. They were very professional and completed the job in less time than estimated. They also helped us obtain rebates/incentives to lower the cost of the project. We highly recommend this company.”
