In my local area, central air conditioning system for the beach house isn’t necessary; The summer time season is fairly short. There are years when the whole season is cold and wet, and for those few weeks, both of us can manage with a combination of box fans, open windows and window air conditioning systems, but i wasn’t gratified with this solution. The open windows allow in all sorts of pollen, bugs, fumes, dust and other allergens. The box fans stir up those contaminants and don’t supply much relief. The window air conditioning systems are unbeautiful and only cool a single room. The rest of the home feels uncomfortable. The two of us sometimes get summer time weather that is brutally warm and humid. I decided it was worth it to invest in a whole-house cooling system, but because I already had a forced air furnace with air duct installed, it wasn’t excessively extravagant. The central air conditioning system is such an improvement. I love the ability to adjust the temperature control and have every room know perfectly cool; Plus, the air conditioning system circulates and filters the air, keeping the home fresher and more hygienic. It also helps with humidity. I spent extra for an Energy Star rated, high-efficiency unit to keep running costs acceptable. The operation is especially quiet and makes for a far more enjoyable living environment, but my whole family sleeps better at night and we’re able to be more productive while in the day, however while both of us love spending as much time as possible outside while in nicer weather, it’s genuinely a joy to step inside at the end of the day. While the air conditioning system might not be necessary, I suppose it’s worth it.
