Understanding and Preventing Common HVAC System Problems

Property owners should be aware of potential problems with their heating, ventilation, and air conditioning (HVAC) systems. Detecting and resolving these issues quickly can improve an HVAC system’s efficiency, reduce energy costs, and help your facility maintain a comfortable, safe indoor environment.

What Are the Key Problems That Arise in HVAC Systems?

HVAC systems are complicated, and they can experience a number of problems that require prompt attention.

• Clogged or dirty air filters and ducts: Dust, dirt, allergens, contaminants, mold spores, and other pollutants build up in HVAC systems. Dirty filters, ducts, and coils can lead to poor air quality, and accumulated dust, allergens, and other particulates can impact occupant health. Dirty filters also restrict airflow, reduce system efficiency, increase energy consumption, and damage the HVAC system.

• Malfunctioning components: Failing fans or blowers can lead to poor air circulation and raise energy consumption. Compressor problems, indicated by loud noises and poor temperature control, can lead to insufficient cooling or heating. Electrical problems, including faulty wiring, loose connections, and damaged components, can lead to system malfunctions and risk damage or total shutdowns. Clogged or blocked condensate drains can increase humidity and lead to water damage and mold growth. Insufficient airflow or refrigerant issues can cause evaporator coils to freeze, potentially damaging the compressor.

How Can Facilities Prevent Problems With HVAC Systems?

Facility managers or business owners should implement regular maintenance programs and watch for signs of problems to ensure the ongoing efficiency and reliability of their HVAC systems. Addressing issues promptly can prevent costly repairs and disruptions to business operations.

Most HVAC manufacturers recommend scheduling a professional pre-season service and maintenance during the year. Ideal times for maintenance services are before winter and summer, ensuring that your system is functioning properly before the high HVAC demand seasons.

Best practices from the National Air Duct Cleaners Association suggest ductwork cleaning every three to five years and more frequently if your facility is susceptible to dust or has experienced a recent fire. Coils and air handling units should be cleaned according to manufacturer recommendations. Although the duct-cleaning process is invasive and time-consuming, it is critical to ensure your system’s efficiency, avoid excessive energy bills, and avoid costly breakdowns that require system repair or replacement.

Who Should Perform HVAC Maintenance?

While facility staff can change HVAC filters, more complicated cleaning processes are best left to professionals. Handling ducts and equipment improperly can break your HVAC system or compromise its airflow. Plus, experienced professionals understand how to access ductwork without allowing new particles to enter.
