Yost & Campbell

Yost & Campbell has earned its place as a trusted air conditioning contractor serving Mt Vernon and the greater Westchester County region for over three decades. With a remarkable 4.8-star rating drawn from 2,739 homeowner reviews, the company operates around the clock with full 24-hour availability across every day of the week. This locally-rooted HVAC business holds its license in good standing and has built a reputation for transparent diagnostics, honest assessments, and repairs that last.

What distinguishes Yost & Campbell from neighboring contractors is their dedication to solving heating and cooling problems that others walk away from. Their technicians arrive prepared to diagnose complex issues thoroughly, whether it involves a malfunctioning gas valve, a struggling boiler, or a system showing signs of premature wear. The company participates in manufacturer incentive programs like the EASE offering, helping homeowners access equipment upgrades and rebates when replacement becomes the smarter long-term choice.

Customer testimonials consistently highlight specific team members who go beyond standard service calls. Mario recently spent late evening hours troubleshooting a heating system that multiple technicians had misdiagnosed, explaining each step until the homeowner felt completely at ease. Angel provided a comprehensive maintenance assessment that outlined not only the current system health but projected longevity and upgrade timing, what one reviewer called advice that helped their family make the right decision for their budget and comfort.
