Local Services Ads (LSAs) and traditional PPC each have a place in a healthy HVAC marketing mix. LSAs win on trust and cost-per-lead in emergency demand, while PPC gives you granular control over messaging and landing pages.
The right split depends on your market competitiveness and season. In peak cooling months we often shift more budget to LSAs to capture urgent demand, then lean on PPC for maintenance-plan and replacement campaigns in the shoulder seasons.
