Installing an air conditioner without any windows or doors can be challenging, as these are typically the primary means of ventilation and exhaust for air conditioning units. However, there are a few alternative options you can consider if you still want to cool your home. Here are a few possibilities:
Ductless Mini-Split System: A ductless mini-split air conditioner can be installed in homes without existing ductwork. These systems consist of an outdoor compressor unit and one or more indoor units that can be mounted on the walls or ceilings. The indoor unit blows cool air into the room and returns warm air to the outdoor unit through refrigerant lines. This type of system requires professional installation.
Portable Air Conditioners: Portable air conditioners can be an option for cooling individual rooms. They typically have a flexible exhaust hose that needs to be vented to the outside. You can vent the hose through a small opening, such as a window, using a specially designed window kit or a DIY solution like a makeshift panel or an insert. However, it's important to ensure a proper seal around the hose to maintain efficiency and prevent warm air from entering the room.
Through-Wall Air Conditioners: If you have an exterior wall in your home, you could consider installing a through-wall air conditioner. These units are designed to be mounted directly through an exterior wall, and they require a hole to be cut for installation. Through-wall air conditioners typically have an integrated sleeve that provides a proper seal between the unit and the wall.
Regardless of the option you choose, it's important to consult with a professional HVAC technician to assess your specific situation, determine the feasibility of installation, and ensure proper sizing and ventilation. They can provide expert advice and help you select the most suitable cooling solution for your home.
