Having problems with your Air Conditioners ?
High Pressure Shut Down
Hi,\015\012 If the outside fan is running when this takes place and the condenser is clean, I believe its the High Pressure Control that is bad. There is a possibility that if the unit was opened and air was allowed to get into the refrigerant part on the system that it could cause this problem but unless the system was worked on just prior to this starting, I don't think this would be the case. The part about draining the freon to check the orifice doesn't sound right, This could be done with a pump down by closing the suction line valve at the condensing unit which leaves the freon in the condensing unit. If they charged you to replace the freon, I would question them about this procedure. Hope I have helped.\015\012kstfas

Do the H series Hayward heaters have a low water pressure shut off valve and or a high temp limit switch?
Yes..... they have both. The limit switches are located near the inlet/outlet water manifold. The water pressure switch can be found from the front of the unit. Find the device at the end of the 1/4" copper tubing. It will have 2 wires connected to ... Air Conditioners
I have a Carrier HFC-134a commercial chiller unit model 30HXA076RY-561AA. It runs 2 sides which are labeled A1 and A2. Over the past few weeks now the A1 side keeps shutting down (almost daily sometimes more often) with an alarm that says "A1 Failure - High Pressure Switch Trip". We've had a local hvac company come in to look at it a few times... One of them they were here for nearly 2 full days. They replaced some filters and did some diagnostics... Racking up a huge bill... But haven't solved

We had our furnace replace this winter, our air was only about 8 years old and working fine so we didnt change it, well now , the air coming out of the vents are cold, but the condenser NEVER shuts off and the thermostat never reads what it is set on, it stays 2 or more degrees higher, the company that installed the furnace checked the air and said everything is working fine, and leaves me high and dry and HOT... the freon level is good, the pressure reading is good, but the house is hot and the
Hi, if the new furnace they put in did not have the right size coil to match the outdoor unit, it would run all of the time and not cycle off. Lets say if it is a 3 ton condenser, the indoor coil must be a 3 ton coil as well. If they put a 2 !/2 coil ... Air Conditioners
What should the high pressure line read to be fully charged on my RUUD UAKA-042 a/c unit? The specs on the unit has a design pressure of 300 PSI on the high pressure line and 150 PSI on the low pressure line. Is that the operating pressure for the high pressure charge or the maximum value that the system can with stand before rupturing a line or component?
That is a desing pressure not an operation pressure. opperating pressuers will vary with load so pressure alone will not tell you if you have the proper charge. the proper method is with superheat or subcooling, depending on the type of metering devi ... Ruud UAKA042 Air Conditioner

1994 corolla-I charged the air cond., and it was cooling fine. After about a mo., it was not cooling very good. I assumed it had a small leak. I put my guages on it and the low pressure was running 15 to 20. The high side was reading about 150.I put a can of stopleak and detector in it. Then I put a can of freon in it. While I was putting the freon in it the pressure started to drop on both the low side and high side. Now the low side pressure is running about 15 and the high side is running 0.W
Hi\015\012\015\012\015\012Thanks for using FixYa. This has happened because of the low side pressure on your AC pump isn't kicking on, because when the pump is off, the pressures equal out and the low side shows a high ... Air Conditioners
Heatline boiler pressure is very high, exceeds normal pressure (arrow is shacking at level 4 which makes a lot of noise). By opening tap in the bathroom, lowered the pressure down to 3.5 (noise is vanished but there is still a high pressure).How to low a pressure down? Heatline boiler is turned off.

A/c switch I am trying to find out how to replace the high pressure switch in my, RUUD central A/C unit. The system is empty, as the high pressure switch was leaking.I am having trouble where the copper line, on the switch, goes into the high side line. I can see it is not soldered.Do you need some kind of special tool and if so how and where I can buy one. Thank's for your HELP!!!!

I have a 1993 yellowstone camper with a coleman wall thermostat. on the bottom of it- it has a heat/cool switch on one side and the other side has a low-high-fan switch. when we run it on low or high it gets cool but the fan never shuts off.if we put it on fan it shuts off with the compressor but it doesn't blow cool air. any advise?

Insufficient cooling in my mercedes 300e 1989. When i hook the manifold gauge and turn on the AC, the low side pressure shows ~70psi and high side 200 - 230psi(low side pressure stays constans and high side not to)
1989 year would indicate the system uses the Old CFC R12 refrigerant. 70 PSI equals about 70°F . This is not enough pressure difference to give you any cooling. Sounds like your compressor has bad valves. Replace compressor. ... Air Conditioners
