Heating and Auto Air Conditioning Tips
Too much or too little refrigerant in your Air Conditioning system is a major cause of A/C compressor failure and it can also waste fuel.
The proper amount of refrigerant in the system is very critical to A/C operation. Running the system low on refrigerant causes compressor failure as the system lubricant flows with the refrigerant. Low refrigerant flow means poor lubrication. If your A/C system works but just doesn’t seem cold enough, it is a good idea to get it looked at sooner than later.
Today’s air conditioning systems do not have a way to visually check the refrigerant level and the only accurate way to get the proper amount into the system is to recover the refrigerant, measure it and then put the proper amount back in. Many times when the A/C system isn’t working well, someone may add more refrigerant by just “guessing” by when it seems to be working fine. It is easy to get too much in at this time which causes higher pressures and heat, which causes mileage loss and eventual compressor failure.
Other things that can cause air conditioning performance problems are not running in “recirculate” in hot weather, cooling fan problems, debris in front of the radiator/condenser and heater control problems.
We recommend having the system evacuated and refilled every 3 – 4 years, as even a system with no visible leakage may lose a little every year.
To see if your A/C system is performing, measure the outlet temperature at the vent with an accurate thermometer. Drive the car with the A/C on “max”. With temperatures in the 70’s to 80’s Fahrenheit the outlet temperature should be around 35 to 48 degrees.
Car air conditioning before 1994 used freon called R12 which was found to be harmful to the ozone. They can be retrofitted to use R134. The correct way to do it is to remove and drain the oil in the compressor, replace the accumulator or drier and flush the old oil out of the system as it is not compatible with R134a. You can just replace the accumulator or drier, skip the flush and oil drain and recharge the system but efficiency may not be very good. With changing to R134 you also need to refill the the system with R134 compatible oil also as the mineral oil used with R12 will not flow with R134 and will just pool in different areas and be useless.
