Angi Inc. runs the largest home services marketplaces in the US, combining the former Angie's List, HomeAdvisor, and related brands after their 2017 merger. For HVAC contractors, Angi offers three main ways to acquire jobs: a free profile to collect reviews and show up in search, Angi Ads for sponsored visibility on the Angi site and app, and Angi Leads (formerly HomeAdvisor Leads) where the platform matches homeowner requests with contractors on a pay-per-lead basis.

Because HVAC jobs are high-ticket, leads are usually more expensive than average - published pricing suggests $18-$55+ per lead and most contractors spending roughly $300-$2,500/month on Angi programs. Homeowners interact via the Angi app and website, where Instant Booking allows them to schedule HVAC service online in real time. Contractors registered in the network are prescreened with criminal and financial background checks. Angi is rarely a standalone marketing strategy, but it is a common supplemental channel, especially for newer HVAC businesses building review volume and filling schedule gaps.

Angie's List was founded in 1995 by Angie Hicks and William Oesterle; HomeAdvisor dates back to 1998; Angi Inc. in its current form was formed in 2017. HomeAdvisor is headquartered in Denver, Colorado, with additional offices across the US, and Angi is part of IAC.
