Common Culprits Behind Decreasing HVAC Energy Efficiency

Commercial facilities depend on HVAC systems day in and day out to keep employees and customers comfortable and protect products and equipment. Of course, the continued use of heating and cooling equipment can result in high energy bills, especially if your system isn't operating at peak efficiency. Which problems could be decreasing your HVAC system's energy performance? The team at Ron Hammes Refrigeration in La Crosse, WI, has your answers.

Top 3 Causes of Declining HVAC Efficiency

1. Dirty Chiller Tubes

With centrifugal chillers, the buildup of microbes and other deposits in the chiller tubes can significantly decrease energy efficiency. This is because the blockages make it harder to transfer heat, requiring more energy to be used to complete the process. A thorough cleaning of the tubes with a water treatment is often enough to resolve the problem, resulting in energy savings of 10% to 35%.

2. Thermostat Control Issues

Quite often, one of your facility's biggest energy wasters isn't the result of a major mechanical malfunction. Issues related to the thermostat, including resistor malfunctions and issues with cycling or continuously running fans, can drive up energy usage. Even something as simple as an improper temperature setting or the lack of a nighttime setback can waste energy. Enlisting an HVAC professional to check the thermostat system and optimize its settings can yield major savings.

3. Rooftop Sensor Failures

Rooftop units are prone to an array of sensor issues, including broken wires, failed sensors, and non-adjustable snap discs. This can cause the system’s economizer to stop working, driving up energy costs. Repairing the failed sensors can improve energy efficiency by up to 40% in some cases.

Is your HVAC system not living up to your energy efficiency standards? Whether you could benefit from air conditioning repair or a new equipment installation, the team at Ron Hammes Refrigeration will help you find the best solution for your business.
