Newer HVAC units tend to run quietly. Older versions may emit sounds when the system starts up or when it's running, and it’s considered quite normal. However, if the noise is loud enough to interrupt you from binge-watching your latest TV shows, the problem may be more serious.
The home HVAC system is a vital component of your property that helps keep your family comfortable throughout the year. Without it, loved ones would not only suffer through heat waves, but also be at risk of freezing during cold weather.
