Insights

Acquisition tailwinds Deljo was acquired by Heartland Home Services in 2022, indicating potential alignment with larger HVAC, plumbing, and electrical service platforms. This suggests opportunities for bundled service programs, cross-sell of maintenance packages, and integration into a broader partner ecosystem.

Emergency readiness With 24/7 emergency repair service, there is a clear channel for upselling preventive maintenance plans and service agreements that prioritize preventing outages, targeting both residential and small commercial customers in Chicagoland.
