Choose your city
In California, window AC installations must comply with local building regulations and energy efficiency standards, which can vary significantly by city and county. Our technicians are knowledgeable about these requirements, ensuring your installation is code-compliant. We start by assessing the window's structural support and the availability of an appropriate electrical outlet, crucial for the safe and effective operation of the unit.
Given California's varying temperatures, especially the heat in inland areas, proper unit sizing and sealing are paramount. We ensure the window AC is sized correctly for the room to provide efficient cooling without overworking the system. Our installation process includes creating a secure seal around the unit within the window frame. This prevents conditioned air from escaping and unconditioned air from entering, optimizing performance and reducing energy consumption.
