Maintenance Tasks for Commercial HVAC Systems

HVAC systems are one of the biggest consumers of energy for commercial buildings. The most effective way to reduce energy consumption in your commercial facility is through HVAC preventive maintenance. Maintenance provides many benefits including increasing the lifespan of your equipment, prevent unplanned downtime, and function optimally.

Basic Maintenance Tasks for HVAC Systems

While most maintenance tasks need to be performed by a qualified, professional HVAC technician, there are some basic things that building managers or staff can do to take care of your HVAC equipment including:

1. Change air filters – You should check your air filters at least once a month and change them as needed.
2. Visual inspection – It is a good idea to do a visual check of your HVAC system on a regular basis to make sure that nothing looks wrong or out of place.
3. Clean exterior of unit – Clean up any material outside of your unit that could interfere with airflow including leaves, dirt, or grass. Trim back any plants or shrubs that are growing too closely to your equipment.
4. Clear up blockages – Check to make sure that your supply and return vents are not blocked by any materials or furniture.
