Get the most out of your HVAC systems

Is your HVAC system working as efficiently as possible? Is your HVAC system compliant with HSE regulations? Are you experiencing ongoing maintenance issues with your HVAC system? In other words: Is your HVAC system in good shape, or is it costing you a bundle for no good reason?

With any facility evaluation, one of the first areas to check is the heating, ventilation, and air conditioning (HVAC) system. You need to decide how much time you have left in the system lifecycle. If your HVAC system is too old, this system could be sucking energy and wasting your money. It can also cause indoor air quality issues that lead to issues such as SBS. Or your old HVAC system could increase your maintenance bills. If so, then you need to know what the error is in order to be able to fix it.

Energy use is a good starting point because the opportunity for cost savings is significant. Lighting tops the list of potential savings, but the heating, ventilation, and air conditioning (HVAC) system is a close second. Did you know that high-tech HVAC systems can save 30 to 40 percent on energy costs? Nothing to sneeze in. The return on investment in HVAC upgrades ranges from one to five years, depending on the level of system use. This is well worth the money, considering that HVAC systems can last for 10 years or more, depending on use and climatic conditions.

Interestingly, HVAC system design has significant impacts on productivity and energy savings. If you don’t have good controls over your HVAC system, you are wasting a lot of money. It is possible that you are simultaneously heating and cooling different parts of the building at the same time. This is counterproductive and places a lot of stress on the HVAC system.

According to the California Energy Commission, the heating, ventilation, and air conditioning (HVAC) system must be sized to provide the correct airflow, and to meet the calculated heating and cooling loads for each individual room. It must also be installed so that the static air pressure drop across the processor is within the manufacturer’s and design specifications to have the ability to meet the calculated loads.

In addition to proper design and installation, experts encourage regular maintenance of the HVAC system to ensure optimum operation. Air filters must be changed every month, for example, and HVAC equipment must be properly charged with refrigerant and the stove must be properly operated and ventilated.

If you do not have HVAC maintenance crew on site, be sure to contract with a local air conditioning maintenance company for regular checks. This will extend the life of your HVAC and save heating and cooling costs.
