Clean an Air Conditioning Condensing Unit and Recharge Air Conditioning with Freon in an Oldsmobile Alero
The air is getting warmer and its time to get your air conditioning condensing unit in tip-top shape before the summer sun makes the inside of your house feel like an oven. Because your air conditioning condensing unit works by sucking air through its fragile blades, it also pulls in an odd assortment of dry leaves, dead grass, dandelion cotton and dust, all of which clog your unit and affect its ability to cool the air. Before the thermostat hits an all-time high, follow these simple steps to clean out your air conditioning condensing unit so your family can enjoy cool indoor air all summer long.
How to Clean an Air Conditioning Condensing Unit
Shut off the power switch to your air conditioning condensing unit. The on-off control is usually located inside a box or on a block nearby, and should be in the form of a switch or a pull lever. Unscrew the grill on the top of your air conditioning condensing unit and lift the fan out to get to the fins.
Use gloved hands to get rid of leaves and other debris that might have accumulated inside the unit. Use a vacuum with a soft brush to gently clean the fins and remove built-up dirt and loose debris. Be careful not to apply too much vacuum pressure or you may damage the fins.
Straighten any bent or slightly damaged fins using a dull knife or special fin combs available at any small appliance store. If any fins have been crushed beyond repair, call an air conditioning repairman to straighten or replace them. Check the fan motor and the belt-driven compressor located on the bottom of your condensing unit for any lubrication ports, usually found only on older models.
If your unit has them, add five drops of electric motor oil to them. Most newer models have sealed bearings that dont need to be oiled.
How to Recharge Air Conditioning with Freon in an Oldsmobile Alero
Most auto parts stores have leak detection kits. Some of these will seal small cracks or punctures. If you see any other visible damage, take your Alero to a professional to recharge the air conditioning system with Freon.
Start the car and turn on the air conditioner. The air conditioner should be on the coldest setting and blowing as hard as possible so you can get a valid pressure reading. Use an automotive air conditioner pressure gauge included to check the pressure on the Low Pressure Side.
Follow the instructions included in the kit as the instructions vary for different kits. If the pressure is in the acceptable range, take your Alero to a professional for service. Attach the refill hose to the quick connect connector on the Low Pressure Side of the air conditioning system.
This will be the smaller of the two connectors on the air conditioning lines. Allow the air conditioner to suck the Freon out of the can by slowly turning the valve on the refill kit hose. Most kits will have you hold the can upright when you recharge the air conditioning system.
It may take as long as 10 minutes to empty a single can.
Driving around during hot weather with an air conditioner that is blowing warm air is a miserable experience. As long as your cars air conditioning system components are working properly, recharging the air condition system may be all that is necessary to once again enjoy cold air in your Alero. Check your air conditioning lines for damage.
