Review evidence is limited for this business. Delta Sirius claims over 30 years in operation and lists duct sealing, duct cleaning, and commercial HVAC services; however, no customer reviews are available to verify their work quality or service reliability.
Based on limited recent reviews, so treat this as low-confidence.
Most customers return year after year, citing Desmond and his team for on-time service, clean work, and honest troubleshooting without upselling. One old complaint mentioned incomplete work and poor follow-up; the bulk of recent reviews highlight professional service and fair pricing that keeps families engaged for over a decade.
Customers experience fast, skilled work from named technicians like Pandi and Kumar, with clear upfront pricing and WhatsApp communication. A small fraction report unresponsiveness or no-shows, and one job involved a diagnostic error that the business later addressed with full service recovery.
Not enough recent reviews yet to synthesise a reliable sentiment read for this business.
