It might seem new to you, but today’s HVAC systems are built to run for a long period of time, consistently. You might think keeping its fan on can cause general wear and tear, but this is not true.
A properly installed and appropriately used HVAC with a calibrated thermostat may have little malfunctioning. In fact, it helps reduce the load on your system, which helps it to run smoothly, keeping it away from wear and tear or other internal damages. As a result, your system’s life expectancy remains the same.
