6 Critical Points in HVAC Maintenance: System Checks and Preventative Care
08 October 2024
Ensure optimal performance for your HVAC system with these critical HVAC maintenance tips. Learn about system checks and preventative care for your business.
HVAC maintenance is essential for ensuring the efficiency and longevity of commercial heating, ventilation, and air conditioning systems. Regular system checks and preventative care help avoid costly repairs and unexpected breakdowns, which can disrupt business operations. By addressing six critical areas, businesses can keep their HVAC systems running smoothly and efficiently year-round.
1. Regular Filter Inspections and Replacement
One of the simplest yet most essential tasks in HVAC maintenance is regularly checking and replacing filters. Dirty or clogged filters force the system to work harder, leading to inefficiencies, increased energy consumption, and potential system damage.
Filters in commercial HVAC systems should be inspected monthly and replaced as needed to ensure proper airflow and cleanliness. Invest in high-quality filters and set up an automated reminder system to ensure timely replacements.
2. Inspect and Clean Ductwork
Ductwork is a critical component of HVAC systems that distributes conditioned air throughout a building. Over time, dust, debris, and other contaminants can build up in the ducts, reducing efficiency and potentially affecting indoor air quality.
Regular ductwork inspections should be part of a commercial HVAC maintenance routine to identify leaks, blockages, and dirt accumulation. Schedule ductwork cleaning and sealing services at least once a year to prevent leaks and maintain efficiency.
3. Check and Calibrate Thermostats
Incorrectly calibrated thermostats can lead to inconsistent temperatures and energy wastage. For commercial properties, where HVAC systems are often used extensively, this can translate into significant cost increases.
Checking thermostats for accuracy, recalibrating them, and ensuring they are correctly positioned (away from direct sunlight or draughty areas) are key maintenance steps. Consider upgrading to smart thermostats that allow remote monitoring and control of temperatures, optimising energy use.
4. Inspect Electrical Connections and Components
HVAC systems in commercial buildings have various electrical connections and components that require regular attention. Loose or corroded connections can lead to system failures or even safety hazards such as electrical fires.
Inspections should include checking wiring, inspecting connections, and testing voltage to ensure everything operates smoothly. Schedule a licensed electrician to perform a thorough check of all electrical components as part of annual HVAC maintenance.
5. Lubricate Moving Parts
Many components in a commercial HVAC system, such as fans and motors, rely on moving parts to function efficiently. These moving parts need proper lubrication to avoid friction, which can cause wear and tear, reduce efficiency, and lead to premature equipment failure. Regular lubrication as part of HVAC maintenance helps extend the lifespan of the system. During each maintenance visit, ask technicians to lubricate all necessary parts to prevent breakdowns.
6. Perform Comprehensive System Checks
Comprehensive system checks should be done at least twice a year, especially before peak usage seasons. This includes inspecting the entire HVAC unit for any signs of wear, testing the refrigerant levels, and checking for leaks.
These checks can identify potential problems early on and prevent unexpected failures. Schedule pre-season inspections (spring and autumn) to avoid any interruptions during extreme weather periods when the HVAC system is critical to business operations.
By focusing on these critical areas, you can ensure that your HVAC system operates efficiently year-round, minimising the risk of downtime and extending the life of your investment. Contact Oregan Air Conditioning for your HVAC maintenance.
