Compressor superheat is sometimes referred to as total superheat. 6.P (pressure) Pressure is the force per unit area exerted by the working fluid. Pressure data is expressed in three units: psia, psig, and in Hg (vacuum). The primary unit expresses pressure as absolute pounds per square inch (psia). Converting between gage and absolute pressure can be accomplished by the following, P absolute [psia] = P gage ...Based on NOAA records, the year 2022 holds the record for the most 90 °F days in Seattle history. There were 13 days with a high temperature of at least 90 degrees that year. How many so far this year (2024)? It has not reached 90 degrees Fahrenheit in Seattle so far in 2024. As of May 23, the highest temperature this year is 84 °F.The suction pressure depends by the TEMPERATURE of the boiling (evaporating) refrigerant (R-22) in the evaporator (indoor or cooling coil). This temperature should be about 35 to 40 degrees F below the Return Air temperature. IF the return temperature is 75 the evaporating temperature of the R-22 should be between (75-40=35) and (75-35=40).Cooling degree days (CDDs) are a measure of how hot the temperature was on a given day or during a period of days. A day with a mean temperature of 80°F has 15 CDDs. If the next day has a mean temperature of 83°F, it has 18 CDDs. The total CDDs for the two days is 33 CDDs.

That means you will want to check your tire pressure before the sun heats them up. When sitting in the sun or driving, the tire pressure will increase 2% for every 10 degrees F the tire temperature goes up.The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.Low side should usually be ~70-75 psi at that indoor temp and high side should be 170+psi (depending on how dirty your coil is and seer rating). And while you can't tell exactly how much refrigerant you're down without exact numbers for your system (metering device, indoor wetbulb, dirty coil) you can usually tell if you're low.
