some central air systems use metal / tin ductwork (some use plastic)
if the metal ducts are installed improperly the ducts pucker outward when the duct is pressurized by the fan and collapse when the fan goes off. This movement of the metal ductwork causes a banging or knocking noise on every startup and shutdown.
It can sometimes be caused by a unintended blockage of the air flow.
My home air conditioning unit was making a knocking sound more like a whoop whoop type of knock when the main blower motor was winding down. Turned out to be the fan wires that were bumping against the fan cowling - tapped them up. GGB.
The evaporative air cooler is an alternative to conventional central air conditioning. An evaporative air cooling system is more economical to operate than a conventional central air conditioning unit.
your central air need re-gassing It means that you are probably low on refrigerant.
YES!
Electricity
yes
No, but it's a good idea to protect any metal equipment from extreme weather.
Water from my central air conditioning drip pan caused a leak in my celling it was full of water when i shut it down it started to drip
With central air the furnace fan must be running to provide the air to the living space. If the furnace fan is not running then you get no air out of the ducts and the A-coil (the part of the ac system that is in your furnace duct) will freeze and shut down the compressor (the part that is outside).
With the gas shut off, you won't be able to heat your building. If heating the building is not an issue, then yes, the A/C can still be used to cool the building or to simply circulate the air.
inlet not completlly closed @shut down .inlet needs rebuild or comp. being shut down while loaded. always unload comp. for a while before shut down .unless you just like buying and changing air filters!
some times thing like this can have something like a small secondary system shut down. if this has happened to you then don't panic or freak out because it is harmless.
jack the rear of the car up and let the air ride level itself once there down shut off air ride from the trunk
Central air conditioning is much more effective at cooling an area, less noisy and can improve air quality. The area a central air conditioner can cover depends on the size of the unit you purchase. A certified technician can size your equipment to meet the specific needs of your home. The installation details depend a lot on whether you have had it in your home or office before. If not, there is the installation of the components in the attic & your walls. If you have, it is merely replacing a unit outside.
Poo is the meaning of that by Tokyo
That would be the noisy escape of air.
If you mean that the a/c shuts down or blows hot air when the a/c button is depressed then no it should not be doing that................
Ifit has the c68 option (auto air) check the blower control module under the hood
