Why a Window Lock for Air Conditioner is Necessary
As a homeowner, I’ve always prioritized the safety and comfort of my living space, and one of the key elements in achieving that is securing my air conditioner with a window lock. I remember the first summer I installed a window unit; I felt a wave of relief as I enjoyed the cool air, but that relief quickly turned to concern when I realized how easily someone could access my home through an unsecured window.
