Recent Review: Air conditioning failed on a retail building in an area that required constant temp. due to monitoring system computers - an emergency in the opinion of the commercial tenant. We called Cal-Coast in the morning and they were there, as promised, right after lunch. The tech, Jeff, was knowledgeable, very courteous and had the problem fixed very quickly. He answered the building owner's questions about the A/C unit and confirmed that maintenance was up-to-date. The billing for services was entirely reasonable. We would highly recommend this company!
