The Olimpia Splendid Maestro Smart 9 HP heating and cooling unit keeps you comfortable inside your home or business all year. And, impressively, this AC and heater works without the need for an outdoor unit! Instead, the only things visible from outside the building are two grills for intake and exhaust. That means the entire installation process takes place inside. This through-the-wall heating and cooling unit has a 9,000 BTU capacity and can condition spaces up to 300 square feet in size. With its 115-volt plug, it's easy to use anywhere, and you'll get a top-of-the-line compressor that boasts whisper-quiet operation. Made in Italy, it has not only a sleek design but also advanced technology. Using a multifiltering system, it combines electrostatic with an advanced carbon filter to keep your air clean. You get a handheld remote for control, and you can add a wall-mounted wireless thermostat as well.
It can work in spaces up to 300 square feet!
