Replace central air conditioning system

Our small office central air conditioning system failed and Nando and his team responded promptly with quote and quick turnaround. We are Engineers and Contractors ourselves and we have had Keystone help with several projects over the past few years and we can attest to their competence and professional manner of delivering service. Our office staff is once again cool and back to work! Thanks Nando and Keystone Mechanical team.
