Ductless mini-split systems are a great option when central air isn’t available. They’re energy-efficient, work room by room, and way quieter than window units. Pairing them with thermal curtains and proper insulation makes a big difference. Astera Services https://www.asteraservice.com/ offers heating, cooling and appliance installing and repair, and they’ve installed compact cooling systems that work great in homes without ductwork. It’s a solid upgrade if you want comfort without a total remodel.
