Heating, ventilation, air conditioning, and refrigeration accounts for a very high percentage of the energy use in a building. Controlling costs while maintaining optimal comfort levels and adequate ventilation requires making sure HVAC/R systems are operating at their highest efficiency. A number of specialized tools are available to assist technicians in analysis and troubleshooting of HVAC/R systems to ensure they meet that high standard.
