Some think it is far easier to save on energy if you own a house. After all, you have *almost* complete control over appliances and how they run in a house. And there is a certain degree of truth to that. You have greater responsibility over the appliances and their upkeep, but if something goes wrong, you can turn off the unit altogether and come up with an alternative solution – or replace it.
Apartments or specifically the renters that reside in them don’t have those burdens – though they are …

When a portable air conditioner that is in good working order senses (through a thermostat) that the temperature of the air in the room is too high, or above the threshold set, it begins the cooling cycle. Modern window unit air conditioners typically operate in “dual” phases – and cool using one of the phases. This is set at the factory to ensure the most efficient use of energy.
The first phase uses the internal fan. When the fan turns on, air is blown into the room to circulate it. The …

There’s an argument to be made for cleaning your heat registers…actually, there’s several.
First, there’s the energy argument. In theory, especially in forced air systems, air flow is reduced as heat or air registers become clogged and otherwise dirty. Anything that reduces airflow has the potential for jacking up your energy bills because the furnace (or a/c for that matter) has to work harder to attain the desired room temperature.
And for non forced air heating systems (radiant heating for example), if the heating apparatus is dirty, the furnace (or heat source) …

If you have a floor or desktop fan, use the oscillate feature. They circulate the air much better than a fan that’s blowing or moving air in one direction.
