Obviously, we canât directly measure the size of the universe but cosmologists have various models that suggest how big it ought to be. For example, one line of thinking is that if the universe expanded at the speed of light during inflation, then it ought to be 10^23 times bigger than the visible universe.
If you smell burning from your AC unit, you probably have an electrical problem. The burning smell can come from either a blower motor that overheated or a mechanical failure of some sort. This is due to the build up heat of plastic insulation on wires, causing melting and the burning smell in your unit. Also, if plastic, rubber, or other objects get caught in your ductwork, this can cause a burning smell. Even dirty air filters can overheat your AC unit, creating a burning smell.
Save. When the air handler blower of an air conditioning unit continues to run, it indicates a problem that needs to be resolved. When the HVAC is in the heat mode, it can cause a cool draft when the heat is not in the demand mode.When the unit is in the cooling mode, the draft is not so undesirable, but it wastes energy.eplace the thermostat and its cover. Remove the access panel from the air handler, to the controls. This is usually going to be the top panel. Remove the screws, then lift and pull the panel off. If the heat is electric, the fan is probably controlled by a sequencer.
