Baran from Diamond Air Services has performed our HVAC maintenance several times, and he always does an excellent job. He diligently inspects the system to ensure optimal performance and promptly addresses any concerns. Baran is punctual, efficient, and friendly, and we are very satisfied with the continued service provided by Diamond Air.
Diamond Air was my choice over other HVAC companies to replace my outdated equipment. Not only were they professional and courteous, but they exceeded my expectations. I have nothing but positive feedback - the experienced crew, led by the exceptional Jose, addressed all my questions thoroughly. I would confidently recommend their services to my family and friends.
The communication from Howie Vo, the Operations Manager at Diamond Air, was outstanding. They also offer payment plans for unexpected HVAC expenses. The technician, Salvador, was a true professional - he answered all my questions, was friendly and polite, and tested the system while providing maintenance tips before leaving. I would not hesitate to recommend this business to my friends and family.
I have been a loyal customer of Diamond Air Services since 2021, and I cannot speak highly enough of this company. The entire team, from Anthony to Howie to Bobby and Tiffany, are amazing - they are responsive, friendly, and provide VIP service, treating their customers like family. They do not try to upsell, and Anthony even suggests ways to save me money. Recently, during my annual maintenance service, my technician, Sal, arrived on time, explained everything thoroughly, and completed the work efficiently. Thank you, Diamond Air Team!
I hired Diamond Air for duct cleaning and unit maintenance, and the technicians, Baran and Christian, were excellent. They were friendly and professional, cleaned up after themselves, and were mindful of not tracking any dirt inside my home by wearing shoe coverings. I highly recommend Diamond Air for all your HVAC needs.
