Rodolfo was our technician. He arrived on time, gave us an estimate of how long the job would take and explained the process fully so we understood exactly how the service would take place. The company takes pride in their work and has the technicians take before/after pictures so we were able to see the difference. In addition, they have their technicians covers their shoes to protect your flooring. Our technician Rodolfo was efficient, thorough and completed the job on time. The vents are not just vacuumed, they are scrubbed...what a difference! Thank you Rodolfo!!!!
