Knowledge, Professionalism & Dedication
“Miguel, HVAC technician from Cardinal Plumbing Heating & Air, came to my home to inspect the HVAC system and vents. I had recently bought the house and had no prior HVAC history, so I wanted to ensure everything was in good condition. Following the inspection, Miguel provided me with solid recommendations. His knowledge, professionalism, dedication to quality work, and comprehensive report gave me peace of mind. I was so impressed that I signed up for Cardinal’s $9.99 monthly service contract. “
Experienced, Comprehensive, and Very Courteous
“Cardinal just completed their routine customer care of the plumbing in our multilevel single family home. The lead plumber was experienced, comprehensive, and very courteous. He explained his findings and recommendations and gave practical advice without pushing costly improvements. I appreciated his attention to his service for us while providing guidance to the plumber trainee who accompanied him— unlike other companies who send trainees solo to do the job with experts reachable by phone. Cardinal clearly stakes their reputation on providing onsite expertise. This is why we continue to stick with Cardinal.”
