As an expert in the field of HVAC, I have seen firsthand the importance of proper maintenance for air conditioning systems. It is a crucial aspect of keeping your system running smoothly and efficiently, while also minimizing costs. However, not all maintenance tasks are created equal. In fact, 80 percent of the results you get from preventive building maintenance come from a small fraction of the tasks your maintenance team performs on a monthly basis.
This is where the 80 20 rule for HVAC comes into play. The 80 20 rule, also known as the Pareto principle, is a general rule that states that 80 percent of effects come from 20 percent of causes. This principle can be applied to almost every department in a company, including maintenance. In the case of HVAC systems, it means that 80 percent of your maintenance activities should be proactive in nature, while a maximum of 20 percent should be unplanned maintenance.
The 20° rule is a specific application of the 80 20 rule for HVAC. It states that an air conditioning system should not be configured less than 20° below the outside temperature. For example, if it's 95° outside, then the thermostat should be set to 75° or higher, but not lower than that. By following this rule, you are ensuring that your air conditioning system is not overworked and is operating at its optimal condition.
The logic behind the 20° rule is simple. When you set your thermostat to a temperature more than 20 degrees cooler than that of the outside air, your air conditioning system has to work harder to maintain that temperature. This not only leads to higher energy consumption, but it also puts unnecessary strain on your system, increasing the likelihood of breakdowns and the need for costly repairs. Of course, it's important to note that the 20° rule may vary depending on factors such as your location, the model of your air conditioner, and the size of your home.
It's always best to consult with a professional HVAC technician to determine the most suitable temperature setting for your specific system. By following the 20° rule, you can significantly reduce the amount of energy you use and the amount of maintenance your air conditioning system needs. This translates to lower costs in the long run. Planned maintenance is typically more cost-effective than unplanned maintenance, as it involves regular check-ups and minor repairs rather than major breakdowns and expensive repairs.
In summary, the 80 20 rule for HVAC means that 80 percent of your maintenance activities should be proactive in nature, while a maximum of 20 percent should be unplanned maintenance. And when it comes to temperature settings, never set your thermostat more than 20 degrees cooler than the outside air. By following these guidelines, you can maximize efficiency and reduce costs for your air conditioning system.
