Abstract


Decreasing the energy consumption or reducing the energy wastages of Heating, Ventilation and Air Conditioning (HVAC) Systems is becoming increasingly important due to rising cost of fossil fuels and environmental concerns. Therefore, finding novel ways to reduce energy consumption in buildings without compromising comfort and indoor air quality is an ongoing research challenge. Thus, this research was conceived to study maintenance of the major components of the HVAC and its energy consumption implication as well as possible energy saving strategy that can be adopted. It was pursued, by means of literature review and field survey entailing the use of a well-structured questionnaire. A total of three hundred and forty-two (342) questionnaires were returned adequately and the responses were analyzed using the computer SPSS software version 25. The result revealed among others that, the most maintained component of the HVAC system are the chillers;the maintenance of the HVAC systems was inadequate and the mmaintenance of the HVAC systems was informed by the following facts in the order of severity; availability of fund, faulty operation of the system and in few occasion it is a normal maintenance routine.There is key strategy for saving energy using HVAC system. The maintenance of HVAC installations significantly affects its energy consumptions in the area. Thus, the study recommends among others: Uniformity in the maintenance of all the HVAC components, and a prompt response to the need for the maintenance of HVAC installations
