The answer to 'should I get central air or' is that central air conditioning is generally the better choice for most homes compared to window units or portable ACs. Central air provides whole-home cooling, improved energy efficiency, and better air filtration. However, the upfront cost is higher and installation can be more complex.
Central air conditioning systems use a network of ducts to distribute cool air throughout your home, while window units and portable ACs only cool a single room. This makes central air a more effective and efficient option, especially for larger homes. Central systems also come with features like programmable thermostats and air filters that can improve indoor air quality. The tradeoff is that central AC requires professional installation of the outdoor compressor unit and ductwork, which can be a significant investment. Window units are often a more affordable DIY option, but less effective for whole-home cooling.
