If you haven’t set up AC maintenance yet in Statesville, NC, you’ll want to do so before summer hits again. The fact is that almost every HVAC expert recommends an annual AC tune-up for all systems, be they ducted heat pumps or the ductless kind. It also doesn’t matter how old the system is. A brand-new unit will start to wear down with regular use, and it will develop problems that are indiscernible at first but gradually grow into bigger, more expensive issues.
