Commercial HVAC Preventive Maintenance Checklist

21 October 2020

Heat, ventilation, and air conditioning (HVAC) systems play a vital role in commercial properties. They basically regulate the temperatures and ventilation of the rooms and areas that can be found on these types of properties. The lack of high-quality equipment in an HVAC system can easily affect the condition and performance of the whole commercial business operations. Even the absence of regular repairs and maintenance of these systems can already affect energy consumption and overall utility expenses.

So, to avoid any issues regarding energy consumption, utility expenses, and overall performance of the business, you must allocate some of your valuable resources to the preventive maintenance of your HVAC system. Preventive maintenance can easily spot HVAC system issues that may gradually affect its operations and subsequently destroy some of its integral equipment or components.

To help you out, here are some things that you should do in carrying out HVAC preventive maintenance.

Maintaining Air Filters

Air filters are designed to prevent allergens, pollutants, and other tiny elements from entering the property. As they filter and gather these elements, they may eventually become dirty and clogged up. The accumulation of elements can become faster during heavy use months. And so, as part of HVAC preventive maintenance, these air filters must be assessed and changed regularly. Their inspection or assessment must be typically done at least once per month. Their replacement, on the other hand, must be done every three to six months, depending on their situation and the manufacturer’s instructions.

Thermostat Programming 

A thermostat is vital to HVAC systems as it can detect the temperature of equipment and perform actions that will maintain the set or desired temperatures. Given its importance, the process of thermostat programming should be done whenever temperature adjustments on the property vary depending on their usage. Programming the thermostat is typically initiated at the beginning of the heating and cooling seasons. Normally, thermostat programming is done every month. However, it would be best for the thermostat to be programmed as each season comes to effectively reduce energy usage.

Cleaning of Components

As part of the preventive maintenance of commercial HVAC systems, there are key components that must be inspected and cleaned regularly. Some indoor components that must be inspected and cleaned regularly include air filters, blower assembly, ignition system, combustion blower housing, condensate lines, evaporator coils, drip pan, and burner assembly. Another set of components that must be inspected consistently are heat exchanger, flue system, duct system, and electrical wirings and connections. Outdoor components like the compressor, coil, fan motor, and blades must also be checked and cleaned.

With HVAC preventive maintenance, you can expect a significant decrease in your overall energy consumption and expenses. Additionally, the condition and performance of your HVAC components can be maintained as they are assessed, cleaned, or even repaired before their condition gets worse.
