My beach house is around 2 hundred years seasoned and harshly big. It’s 2 stories with a full attic, high ceilings and lots of pressing windows. The walls are not officially insulated and several of the windows leak air. I live in an section with dire year round weather, and all of us rely heavily on the gas furnace and air conditioner. My beach house is difficult to heat and cool and costs me a fortune in energy bills; Certain rooms are exposed to the midday sunlight and tend to get warm, other rooms are shaded and get hit by the wind and are always a bit chilly. The Heating and A/C system is too old to update to zone control, so all of us have a central temperature control. If I adjust the temperature setting to accommodate certain rooms, the whole beach house ends up either way too hot or chilly cold. Rather than invest in a whole new gas furnace and central air conditioner, I spent a lot less on a ductless multi-chop system. The ductless heat pump includes a single outdoor compressor connected to several indoor air handlers. The air handlers mounted on the walls of several rooms and allow for independent control over heating and cooling. Each air handler has its own temperature control. Plus, the ductless system is lovelyly energy efficient and features WIFI connectivity. I can manage the temperature setting and adjust fan speed from an app on my cellphone. Despite the small size of the air handlers, the system is quite powerful. It can heat up or cool down a room honestly quickly and maintains a nice, even temperature. I savor that the ductless heat pump filters the air, keeping these rooms cleaner and ensuring superior air quality.
