Minimising Disruption with Pre-Fabricated HVAC Solutions
Minimising operational disruption is a core priority at Oltec FM, achieved through our strategic approach of manufacturing HVAC components offsite before installation at your Yarm, North Yorkshire property. Our workshop-based fabrication process allows us to construct ductwork sections, pipework assemblies, and system modules with precision and quality control that would be impossible in a live building environment. When installation day arrives, our engineers simply assemble these pre-made components quickly and efficiently, drastically cutting the time required onsite. This approach is especially beneficial for properties with limited access windows, sensitive operations, or occupied spaces where traditional extended installation periods would be impractical or costly.


Made-to-Measure HVAC Systems for Maximum Efficiency
Space optimisation and energy efficiency are fundamental considerations in modern HVAC design, and The Oltec Group excels at creating made-to-measure systems for Yarm, North Yorkshire commercial properties. Rather than forcing generic solutions into your building, our design team creates bespoke configurations that utilise every inch of available space intelligently. From compact plant rooms to complex ceiling void ductwork layouts, we engineer high-efficiency HVAC systems that deliver maximum performance from minimal footprint. This custom approach means your system operates at peak efficiency because it has been designed specifically for your building's dimensions, usage patterns, and performance requirements, rather than adapted from a standard template that inevitably involves compromises.
Comprehensive SFG20-Compliant HVAC Maintenance Programmes
Oltec provides comprehensive building-wide HVAC maintenance services throughout Yarm, North Yorkshire, adhering strictly to the SFG20 standard for planned preventative maintenance. This industry-leading framework ensures every aspect of your heating, ventilation, and air conditioning systems receives appropriate attention at specified intervals, maintaining safety, efficiency, and environmental compliance. Our maintenance programmes address evolving UK regulations including the F-Gas Regulation, which mandates that businesses phase out high-GWP refrigerants such as R404A and R410A by 2025. We proactively manage your transition to eco-friendly alternatives like R32, ensuring you avoid substantial fines, maintain system efficiency, and prevent operational disruptions whilst meeting your environmental responsibilities and legal obligations.
