In heat mode, a dirty air filter causes low airflow across the condenser. This can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units. So we replace the compressor (same model #), replace the liquid line filter dryer, and evacuate to 500 microns.

Suction Pressure/Low Side. Suction pressure tells us several things. The first thing it tells us is what the boiling temperature of the refrigerant in the evaporator is. If the suction pressure is below 32° saturation temperature, the evaporator coil will eventually freeze.This accept goes tp Regan. You will need to block head pressure to get pressure up high. It is difficult to charge when it is cool. Must be at least 70 degrees in house. Block condensor and get head to 200 to 220 range and check subcooling and super heat. The TXV will only control to 10 to 12 degrees superheat so you may be reading a lower suction.That’s with an ambient temperature of 70 – 74 degrees farenhiet. As the ambient temp goes up, so should the low side and high side pressures. ... What is the low side pressure of R22? Example R-22 Refrigerant Temperature vs Pressure Data.

The red, high side gauge is used to measure the high pressure side of the a/c system. This gauge has no markings that indicate vacuum. It reads positive pressure only. The working pressure of this gauge is also much higher than the low side gauge. Notice the scale on this high side gauge reads from 0 to 500 PSI.

See corrective steps for low suction pressure. High suction pressure.we note (and you probably know better than I) that making sense of any refrigerant pressure reading requires also a note of the ambient temperature. If we take 75°F as an example point, R410 low side typical pressure would be about 120 psi and the high side between 410-420 psi. Your high side is a little low.The condenser comes charged with 15 feet of 410A. My install has 40 feet of 3/8" and 7/8" line total --- leaving 25 feet needing additional refrigerant. (Goodman suggest adding .6 oz per foot of liquid line) but that seems to be high. At the present time I am setting at 308 (High Side and 143 Low Side with no charge added beyond the 15 foot ...Can't raise low side pressure above 50psi. The evaporator coil of my 15 year old Rheem AC system has had a slow leak for the last few years. So I've been adding app. 7lbs of R22 at the beginning of every summer. I've been able to get the low side pressure up from app. 10psi to 55psi, which has been enough for the system to cool the house.You asked for the temperartures of the high side line and the low side line as they leave/return to the condensing unit. The high side line tempersture was about 90 degrees F and the low side line was about 60 degrees F. This unit is a 1990 conventional A/C system. Maybe after 20 years of good service, I should not be trying to repair the problem.I have an r22 system with an air handler mounted horizontal in my attic. My low side pressure would not climb above 28. I was told I had restriction in my evapoator. Replaced the evap. Flushed every line with nitrogen. Had good flow through lines. Low side only gets to 50 with a head pressure of 290.. Air return and vents wide open no restriction.I will be sharing a pressure chart that may help you troubleshoot low pressure symptoms, high pressure symptoms. ... For 410a this should be around 16-18 degrees F. For R22 it may be around 17-21 degrees F. A delta T reading may not be the most accurate way to measure a charge in a system, but it should help deciding whether you should hook up ...That means that the pressure of R454B is the same on the high side and low side. ... we can read that the pressure of liquid R454B on a 70-degree day is 192.5 psig.

At the present time I am setting at 308 (High Side and 143 Low Side with no charge added beyond the 15 foot ...R-404A History. R-404A rose to prominence in the late 1990's with the phasing out of CFC and HCFC refrigerants like R-12 and R-502. There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A's reign however was short lived.People also inquire as to what the typical operating pressure for a 407c vehicle is. R407c will have a low pressure (suction) of about 50 psi if this is always evaporating above zero, 4 or 5 degrees Celsius. and a cooling cycle with a high pressure (discharge) of about 280 psi, or 55 degrees Celsius. The amount of standing pressure (the system ...Watch on. We typically measure liquid line temperature with a temperature clamp outside at the condenser. Normally, the liquid line temperature shouldn't change very much; even in cases when you have exceptionally long line sets or if the liquid line has been routed through hot areas, you shouldn't see much more than a two to three-degree ...Discover expert tips for troubleshooting well water issues, including low pressure and discoloration.

I thought it had the same issue last year, but in fact it was 2 years ago that it needed a charge. So, it has a small leak somewhere. The rip-off company charged me $350 for 2 lbs of R22. The suction side was at 40 psi yesterday and he brought it up to 60 psi. It was cool out, about 65 degrees.

Optional Info … read moreR22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).Connecting to the low side only, the result was a pressure reading that would be considered far below normal. Based on that information, the technician decided to add refrigerant. ...
