Your HVAC system is draining energy faster than usual. How can you identify and resolve the issue swiftly?

1 Check Filters

One of the most common reasons for an HVAC system to use excessive energy is clogged or dirty filters . These filters are designed to trap dust, pollen, and other airborne particles, but over time they can become saturated, restricting airflow. Your system then has to work harder to circulate air, leading to increased energy consumption. You should inspect your filters monthly and replace them as recommended by the manufacturer, typically every 90 days. If you find that filters are dirty well before this period, it may indicate that they are facing more contaminants than usual, which could be a sign of other issues in the environment.

2 Inspect Ducts

Your HVAC's ductwork can be a culprit in energy waste. Leaks, holes, or poor connections in the ducts allow conditioned air to escape before reaching its intended destination. This loss forces your system to run longer to maintain the desired temperature. To identify duct issues, you can visually inspect exposed ductwork for signs of damage and feel for air leaks. Sealing any leaks with duct sealant or metal tape and ensuring that all connections are tight can significantly reduce energy loss. Additionally, consider insulating ducts that pass through unconditioned spaces to maintain the temperature of the air as it travels through your system.

4 System Maintenance

Routine maintenance is critical for keeping your HVAC system running efficiently. Neglecting maintenance can lead to worn parts, inefficiencies, and eventual breakdowns. Schedule regular professional tune-ups to ensure that all components of your HVAC system are in good working order. During these check-ups, a technician will lubricate moving parts, check refrigerant levels, inspect electrical connections, and clean coils and components that affect the system's efficiency. By keeping your HVAC system well-maintained, you can prevent excessive energy consumption and extend the life of your equipment.

5 Upgrade Considerations

If your HVAC system is outdated, it may be inherently inefficient by modern standards. Older systems often lack the energy-saving technologies of newer models. If your system is beyond repair or nearing the end of its lifespan, investing in a new, energy-efficient HVAC system could lead to substantial long-term savings. Modern systems are designed with energy conservation in mind and come with higher SEER (Seasonal Energy Efficiency Ratio) ratings, indicating better performance. Before making an upgrade, assess the potential energy savings against the cost of a new system to make an informed decision.
