No. They can't get through the enclosed system and inside the house there is a filter. When a filter is changed all that is seen is dust.
Central air conditioning is an air conditioning system with a central unit that distributes air to the rest of the house through vents. Some people have air conditioning units that are separate for each room, but most houses today have a centralized unit, usually located outside the home, which pumps air to each part of the house through the ventilation system. That is what is referred to as Central Air conditioning, because there is just one centralized unit cooling the entire place, as opposed to many autonomous units cooling each room.
The outdoor portion of the central ac unit is what gives up the heat from indoors, so it has to be outside. For a more thorough explanation see the question: How does air conditioning work.
Central air conditioning systems are designed to provide ventilation by bringing in outside air. Leaving a window open would tend to defeat the cooling effect.
You mean the outside unit is running and blowing but the inside unit is not blowing? Shut it off! Who ain't blowing? Elaborate please..
your outside unit is buzzing because the low voltage control signal is activating the switch " the contactor" but your unit for some reason is not starting thus no cool air. either your circuit breaker is tripped or you may have other more serious problems. call a licensed hvac service contractor.
The heat transfer coils are in the outside unit where the compressor and fan are to dissipate the heat generated and removed from the inside air.
If your present central A/C is not that old consider just replacing the outside condenser unit, check into that first before considering replacing the entire central A/C system.
yes outside
The air comes from the air outside and the air conditioning system in the car turns this into cold or warm air.
Our house's outlet temperature at the floor register is about 14C/57F on a day when the outside temperature is 30C/86F. But I feel the register temperature is a bit too warm...
Yes, there are free standing air conditioners as well as ductless air conditioners available. The free standing air conditioners are portable and can be placed in any area yor home. Ductless air conditioning units are placed outside the home much like a central air conditioning unit.
