When a commercial HVAC system underperforms, fails, or requires diagnostic evaluation, Vences Contracting Group delivers responsive, technically grounded service. Our licensed technicians are trained on a wide range of commercial HVAC equipment and system configurations — and we document everything we find and everything we do. Section: HVAC Service Capabilities Diagnostic & Repair Equipment-level diagnostics for commercial HVAC systems including RTUs, split systems, VRF, and AHUs. We identify root causes — not just symptoms — and deliver documented repair scopes with clear options for the facility team. System Performance Optimization Airflow balancing, refrigerant charge verification, controls calibration, and efficiency analysis. Targeted for buildings with persistent comfort complaints, high energy costs, or aging equipment performing below design. Emergency Service We provide emergency response for commercial HVAC system failures. Response times and coverage priority are defined in service agreements. Contact us to discuss emergency coverage options for your facility. Reactive Maintenance For facilities without a PM agreement, we provide on-call reactive service for equipment failures and performance issues — with full documentation of work performed and system conditions.
What brands of commercial HVAC equipment do you service?
We service all major commercial HVAC brands including Carrier, Trane, Lennox, York, Daikin, Mitsubishi, and others. Our technicians are trained on multiple equipment platforms.
Can you service equipment that Vences did not originally install?
Yes. We service and maintain commercial HVAC systems regardless of who performed the original installation. We conduct a system assessment to establish baseline condition before beginning a service program.
How do you handle HVAC emergencies?
Emergency response availability and priority are defined in each client’s service agreement. Clients with active PM agreements receive priority scheduling. Contact us to discuss emergency coverage options for your facility.
Do you work on VRF/VRV systems?
Yes. We install and service variable refrigerant flow systems for commercial applications, including multi-zone systems, branch circuit controllers, and integration with building controls.
What documentation do you provide after service visits?
We provide detailed service reports after each visit documenting work performed, equipment conditions observed, readings taken, and any identified deficiencies or recommendations for follow-up.
