Can you use R-134a refrigerant on an air conditioner?
The exception to this is R-134a and automotive applications. Many people enjoy working on their vehicle and buying a few cans of R-134a and repairing your air conditioning system is no big deal to them. This is a rare exception within the refrigerant industry.
Can a AC system run at 65 degrees outside?
At 65 degrees outside temperature yes. The system is designed to reduce air temp 30-40 degrees from the outside temp. If it is 100 outside, it will blow between 60 and 70 degress. If it is 80 outside, it will blow between 40 and 50 degrees.
What kind of oil do I use for R-134a systems?
What Kind of Oil do I Use for R-134a Systems? In most cases you are going to be using what’s known as PAG Oil. PAG oil, or Polyalkylene Glycol, is a fully synthetic hygroscopic oil specifically designed for automotive air conditioner compressors. It is used in R-134a air conditioning systems to lubricate the compressor.
How does the R134a high and low side A / C pressure chart work?
R134a Pressure Gauge Chart This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges.
What should the AC temperature be if it is 80 outside?
This means that it is 80 outside your AC can easily reach 70 degrees, since that is only a 10 degree temperature difference. So even if it is 90 degrees out your air conditioner should still easily reach the 70 degree mark.

What should be the superheat temp of an A / C unit?
Take the difference between the above readings (Suction line temp – Saturation temp) 4. When ambient air temp (Outside air temp) is 75-85 degrees the superheat should be 12-15 degrees, if the ambient temperature is 85 degrees or over the superheat should be 8-12 degrees. 5. If superheat is low then flooding the evaporator.
Can you run an air conditioner at 58 degrees F?
In most cases, especially in homes, you should not run an air conditioner at 58 degrees F or lower. The air conditioner does function, but you are going to burn out the compressor fairly quickly.
