HVAC System and Appliance Failure

Identify the root cause of HVAC failures in commercial, industrial, and institutional buildings.

Safeguard lives and business continuity from HVAC hazards.

Failures in HVAC systems and appliances carry a substantial financial burden and pose significant safety risks, frequently resulting in severe property damage or health hazards.

A failure in these vital systems can also bring interruption to business operations, incurring substantial costs.

Gexcon has qualified Professional Engineers (PE), possessing extensive expertise in HVAC systems. We are well-equipped to assist in identifying the origin and cause of fires, conducting failure analysis, and addressing mechanical system design and carbon monoxide concerns related to these systems.

Authoritative HVAC system and appliance failure experts

Gexcon's team of experts has undertaken investigations into a wide array of incidents involving heating, ventilation, and air conditioning (HVAC) systems and appliances, encompassing the full range of equipment used for building ventilation, heating, cooling, air circulation, and air filtration. 


Our engineers also have extensive expertise in assessing and testing residential gas systems (both natural gas and propane) and their associated components, as well as in evaluating natural gas pipelines and gas service mains.


Our multidisciplinary team is proficient in analysing all components and systems associated with failures, identifying liable parties, developing efficient mitigation measures for the swift resolution of losses, and communicating our findings clearly.


Moreover, Gexcon utilises advanced tools, such as the FLACS CFD model, to create an accurate portrayal of incident sequences, ensuring clarity for both technical and non-technical audiences.
