A/C Fluctuating Pressures

When i hook up my gauges to the high and low side i have fluctuations in the pressure readings.In the past i have just replaced the unit it self but this time dont have the means to do it.So my question is....Is there anything that i can try to do before replacement??

I dont know what you mean by fluctuating. Do you mean small bounces? If so that can indicate non condensables like water in the line. It could be an indication of a weak compressor.

If they are slowly increasing and decreasing then the refrigerant levels could be the cause as well as a weak compressor. As 22 Yooper said. Make sure you are checking based on the superheat target pressures.

Most Central air conditioning systems are what is termed "A Critical Charged system". Ambient temperatures also affect the pressure reading in the system. Every time you attach a set of gages to a system you will loose some of the charge even if minimal. A set of gages in the hands of someone who does not fully understand the inner working principles of the system could be dangerous to both the system and to the individual in person. To balance a system charge the superheat method is the best. This must also take into consideration the ambient temperature at the time of the procedure. A low superheat at a lower ambient temperature will cause a liquid flood back to the compressor under higher ambient conditions.

WHAT IS PSI SUCTION PRESSURE IN SPLIT AC WHEN UNIT IS IN OFF CONDITION


there is no suction at all when the machine is off as the gas equalizes around the system
all you will read is the pressure of the gas in the system and that will tell you nothing
to read gas pressures you need to know the type of gas in the system , have gauges that can handle the high pressures and have two on a manifold so that you can read suction and high side pressure differences
That way you can see if the system is low on gas or over charged

R-22 home condenser unit low side and high side pressures when running


Pressures look good but to know if it is charged correctly you have to do a sub cool or superheat to know for sure. Rule of thumb is if turn unit it on let it run 10 minutes. If the suction line sweats and is cold. Might be proper charge.

What does it mean when the High side gauge is below 100 psi on my central air


It could be several things.I would start by making sure that the compressor is working.Check high and low pressure while unit is running. If they both read the same then your compressor is not working.The first thing I would do is to add refrigerant to see if it is just shutting down due to low pressure.Depending on how old your unit is and what type of gas you are using you should see pressures on the high side from 250-350 and low side between 55-85.Hope this helps you. Thanks.

What should the pressure readings be for a American Standard Freedom 500 2.5 ton air conditioner be


Hi, this depends on the outdoor air temperature and type of freon this unit has. The hotter it is outdoors, the higher the pressure will be as they use a pressure/temperature relationship. If the unit is R-22 and lets say it is 90* F. out side, the low side or suction side will be at around 68 to 72 p.s.i which would give you an evaporator temperature of 40* F. Head pressure would be at around 90* plus 27*= 245p.s.i. This is if the condenser fan is in good condition and the outdoor coil is clean. If you are using a set of manifold gauges you have the pressure/temperature scale right on it. If the unit has a TXV for metering, you would need to charge it using the subcooling method. On a Non-TXV you would use the superheat method. If you are using the new R-410a freon, the pressure are extremely high in these systems compared to the R-22 system, so make sure you look at the units data plate to read the type of freon. The color of the container is green for R-22 and a Pink for R-410a and the 410 a unit will display a pink warning sticker on the unit to tell you. The pressures on the R-410 would be at 90* F, low or suction side at that temp is around 125 p.s.i., and around 400 to 420 p.s.i. on the high side, much higher then the R-22. You would also need a manifold gauge set made just for the R-410a (AZ-20) as of the extreme pressures in the system. There is never a set pressure to go by as the outdoor temperature will raise and lower the pressure of freon very fast. If you are asking this question because you have a manifold set and are taking a reading, the unit has a charging method pasted right on it from the factory showing what pressure they want it to run at. Your gauges also can be used as a pressure temperature chart, or you can pick one up free of cost at a a/c parts house to keep with you. It will show you how to calculate the charge for your unit. If you are familar with pressures, this should be of a great help to you. I hope that I have helped you on getting the unit charged properly. Please keep me in mind when rating me, as I know you will be kind. Just drop by a wholesale a/c parts house, walk in and ask for a pressure temperature chart, and they will hand you a couple of them. They have very good information and no how on all of the most common freons in use today.
Best of luck

How do i hook my manifold gauges to my residental condensing unit to check pressures


The AC manifold gauges set have the three chambers: the low pressure chamber (left side), utility chamber (middle), and the high pressure chamber (right side).

When technicians connect the HVAC manifold gauge to the air conditioner units, he connects the low pressure side of air conditioner unit to low pressure gauge side.

If he wants to read the pressure in discharge line he connects the high pressure gauge hose to the air conditioner high pressure side.

The utility port (the middle chamber) is a place you connect the hose to vacuum pump, recovery units or add or remove refrigerant from AC units.

Air conditioning gauges is used to measure air conditioner units pressure within closed-system to evaluate or troubleshoot the AC units. Gauges manifold set is the most frequently used item when it comes to refrigerant or pressure.

Air conditioning gauge set allows the HVAC technician to check AC units operating pressures, transfer AC refrigerant, pressure test system, purge the system with nitrogen, and perform other necessary tasks.

The gauges manifold set includes the hoses, the manifold, the valves, the compound gauge (low pressure gauges) and high pressure gauge.

How to recharge a Comfortmaker 10 A/C with R22 refrigerant


Call an HVAC service company. You can't even buy R-22 without an EPA card. And you'll need to proper set of gauges to read the high and low side pressures and, to do it right, be able to compute the dry/bulb/wet bulb temp to determine the proper charge with a charging chart.

For my thesis: 5 condenser problems and 5 solutions


Problem number one.

condenser fan won't come on. solution check the capacitor if good ohm out the fan to see if it is bad. If bad replace fan motor with new one.

2. compressor will not come on. solution check the contactor to see if engaging this applies to problem 1 also. If engages check the capacitor on the herm side if it is bad replace. If good check compressor to see if the compressor is bad. Should it be bad replace compressor.

3. High head pressure not cooling properly dirty condenser coils. Clean coils. With hose and water.

4. Low head pressure frosting accruing on suction line. Check freon levels. Also check inside air filter for being dirty.

5. Condenser unit is failing to come on. solution check the power source check the contactor should the main power be bad check main breaker and replace any slow blow fuses that are bad. Should the contactor be bad check transformer to ensure 24 volts going to secondary side on contactor. Inspect the two wire going to outside unit condenser. replace any broken wire any bad transformer or bad contactor.

Indoor unit temperature between 60F & 70F after R22 charge..


The pressure changes with temperature, it is not a true gauge to ensure a proper charge.

You should have a 15 to 20 degree temp drop across the evap coil. (return air vs supply air)

Can you verify that the compressor is running?
Not the condenser, but the compressor located inside the condenser (outdoor unit)

it really sounds like it is still undercharged.
Check the temp drop, let me know what it is.
Also tell me what the outdoor ambient temp is.

( for example.... 98 degree outdoors with 85 degree indoor temp could result in pressures something like 325 on the high side and 75 or 80 on the low side.
With the exact same unit, but 80 degree outdoor temp combined with 70 degree indoor temp, your pressures could read 215 low side and 55 low side. Not to mention that more efficient units often have higher pressures on the low side because they have more coil space and remove heat more efficiently)

How to hookup refrigerent gauges to central air?


Outside in the condensing unit you'll see the two copper pipes coming from the valves in the condensing unit. atach the hose from the high pressure gauge to the port in the smaller copper pipe (liquid line) and the other hose to the port of the other line (suction line) in there you check the low pressure (68psi) and if is low you can rechrge it, in the high side you should have no much more than 250psi .This pressures are for R22.

I can't seem to get my pressures up on a new 3 ton 13 seer goodman? High side 200psi low 50psi not cooling the house


You might have a bad valve on compressor.Close valve on high side and see if the low side pumps down. Of course you should have your gages hooked up.If your low side doesn't pump down you have a bad valve.
