Ac unit not blowing enough air in bed room - Heating & Cooling

Normal ACs (non inverter) work in the following way

• The AC compressor runs continuously till set temperature is reached in the room
• The compressor then switches off, but the blower fan in the wall mounter unit keeps running. Durint this time the AC fan blows air out at Room temperature (which feels warmer)
• When temperature of room rises then compressor starts running again. During theis period the air coming out from the inner uny is cooled by the condenser coils
• And the process is repeated.... as long as you keep AC running

Ac works this way throught the operation period.
Now if you feel that your AC keeps switching off and on very frequently check the following

• Your AC may be over powered for room *for example a 1.5 ton AC installed in a scenario where 1 ton is enough)
• If there is voltage fluctuation in your area then the compressor may keep shutting don on large voltage swings
  • Solution: Get a Stabilizer
• You have set the temperature setting too high. Max temp suggested for ACs is 25 degree Celsius, any higher will mean the compressor shuts down often. Remember every compressor shutdown and startup draws a high starting current
  • Set AC temperatures between 22 and 24 degrees Celsius
• The thermostat/ Temperature sensor is faulty
  • Get unit inspected by Authorized technician
• There is dust buildup on the outer unit / compressor unit. The dust buildup may cause overheating by preventing efficient heat exchange, This may lead to overheating of compressor and it shuts down to, prevent damage to itself
  • Get unit serviced by Authorized technician
• The fan motor of the outer unit is not working properly
  • Get unit inspected by Authorized technician

Remember to get the AC serviced at least thrice a year to ensure smooth operation

The two things it could be, #1 - evaporator leaking refrigerant - unlikely if unit is still cooling o.k. because window units do not hold a lot of refrigerant and if there is a leak bad enough to blow smoke it would have stopped cooling by now. #2 - the humidity is high and the unit has cooled the air right at the discharge down below the dewpoint, a common occurence in window units and automobiles due to the short duct distance from the evaporator to the air outlet whereas with central air systems having longer duct systems the air gains more heat before being discharged into the room.

7000 btu is very small unit for a small bed room 150 square feet apx.

Check the outdoor side of your unit. Make sure that nothing is blocking the back and also take a hose and clean out the fines of the AC unit. If problem still persists after that, then check to make sure that the internal filter is not blocked or dirty.

check you condenser fan motor make sure it turns on, if ok you must clean the fins on the outside unit,with a water hose , make sure you turn power off first before taking a water hose to unit

The unit may not be big enough. From the model number I am thinking you a/c is a 12000 btu. Which is usally enough for a large room. However if you have an open floor plan or a really large room you may need a bigger or second unit.

Check your Thermostat setting. check the Bulb of the thermostat. place it near the evap. coil.

Threr are suppose to be two sounds comming from the window unit. One, the fan sound and the compressor sounds, (this compresses the refrigerants aove room temperatures (around 240*) & send it to the back coils and remove it to room temperatures and send it to the front coils which if enough freon, it will cool to at least 40*. Turn the thermostat all the way up or down while its off and see if you hear a clicking noise which tells you the thermostat is working which that what calls for cool. If it started loosing cools little by little, then you have a leak, and leaked all the freon out! If it stopped cooling all of once, then your compressor is not kicking in.

that is foam insulation around the seal of the evaparator box pull the unit from the wall remove the cover to get to it and clean or replace it
