This can actually help reduce indoor air pollution, especially when the air quality outside is poor.

Is heating or air conditioning more expensive?

In fact, it can take up to three times more electricity to heat a home than to cool it, which equates to a higher bill. The most efficient way to heat your home is with an electric heat pump. But, most customers don't have a heat pump, so they rely on the heating element in their air conditioner to heat their homes.

Can AC work in winter?

An air conditioner unit helps to regulate the temperature of a room during hot weather. Some units even feature a heating element for cold winter days when you don't need to make the room colder than it is outside. If you use your air conditioner's cooling function in the winter, the coils might freeze.
