Overview

Nextiva is an all-in-one business phone and customer experience platform that consolidates voice, SMS, video, and team collaboration into a single cloud service. Founded in 2008 and headquartered in Scottsdale, Arizona, Nextiva has built a strong reputation among service-based SMBs, including HVAC contractors, for its reliable voice network and especially its US-based customer support.

For HVAC businesses, Nextiva offers the core dispatch-friendly features contractors need: multi-level auto-attendant with after-hours and holiday routing, call queues for CSR teams, voicemail transcription, call recording, and mobile apps so techs can take customer calls from the field. Nextiva also bundles video conferencing and team chat, and its newer Engage and Power Suite tiers add a full AI-powered contact center.

Nextiva pricing scales from the Digital tier through Core, Engage, and Power Suite CX. HVAC shops with 5-50 seats tend to find Nextiva a solid middle ground between lightweight tools like OpenPhone and heavyweight platforms like RingCentral.
