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.
Your outside AC unit may be blowing cold air because it is functioning properly and is working to cool the air before it enters your home. This is a normal operation of an air conditioning system.
Central air conditioning systems do not use water for cooling. Instead, they use refrigerants to transfer heat from inside a building to the outside.
Yes, central air conditioning systems typically pull air from inside the building, cool it, and then circulate it back into the indoor space.
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.
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..
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.
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.
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
Yes, air conditioning units pull in air from outside, cool it, and then circulate it to cool the indoor space.
Yes, a central air conditioning system contains heat transfer coils. These coils are responsible for transferring heat between the refrigerant and the air, allowing the system to cool or heat the indoor space as needed.
