The Ultimate Solution for Your HVAC Replacement Needs
Great Experience
โGreat experience! Chris was amazing at everything. He did a thorough job diagnosing my plumbing issues and described various estimate options. He was not pushy for anything I wasnโt comfortable with. He completed the work efficiently and triple checked his work to ensure quality service.โ
Knowledge, Professionalism & Dedication
โMiguel, 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 Cardinalโs $9.99 monthly service contract. โ
Experienced, Comprehensive, and Very Courteous
โCardinal 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 himโ 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.โ
Excellent Communication and Outstanding Service.
โExcellent communication, top-notch quality, and outstanding service! Iโve tried many companies, but this one stands out with its exceptional professionalism and dedication. They did an excellent job replacing my water heater, water pressure valve, and monitor. Highly recommend.โ
Friendly, Professional, and Pleasant.
โI have never had a better experience with a service company. From the friendly voice on the phone, to the almost immediate schedule of repair, then the professionalism and incredible pleasant Bryan who diagnosed the problem, repaired the issue {actually had the part on the truck} and provided pleasant conversation the whole time! Cardinal Plumbing was a complete joy to work with and reasonable! Thank you.โ
