What To Do If Your AC Is ON But Not Blowing Cold Air

By Manda Plotzker


If it is raining out and the humidity is rising along with the heat there is a good possibility that your air conditioning unit can ice up. When it does your home will heat up quickly. The common misconception is that when your air conditioner is already running to turn the thermostat colder. Don't do this. It will only make the problem worse.

The blower fan that that is inside your air conditioning can sometimes slow in its revolutions. This is caused by a number of things such as dust and lint build up on the bearings or just wearing out over time. In either case, if the motor is still working, this can be easy to miss diagnose. Your AC was designed to have a certain volume of air blown across the coils.

If the motor is working but not up to the proper speed, you may not ever notice it until the cover is removed and electrical amperage test is conducted. Too often AC technicians are do not want to climb in the 14o degree attic so they just jump to the conclusion that the machine is low on refrigerant. They keep adding refrigerant, R22 or 410a, until the unit is overcharged. Over time this improper resolution will cost you big bucks.

High humidity reveals this problem at it's worst. Be careful not to just disregard this issue. Chance are you are loosing up to 35% of your air conditioner's efficiency resulting in a higher than needed power bill.

Say you are sitting on your couch and water is dripping on you. You go and check it out. You realize it's coming from your window unit. You unplug it and begin cleaning up the mess and considering what might have happened. You realize that your curtains have been in front of the unit blocking the cold air from blowing into the room. The curtains are soaked. What happened here isn't good.
