It took me about 20 minutes to install it on my own. As long as you can lift it out the box and up into position you’re good. I did have to break the box to get it out as it was a snug fit. I followed the installation video on you tube which was a big help. I added this to support central air in my house that was struggling upstairs because of my house design. Lovely unit. Very quiet kzbin.infoUgkx_hHgTlzH3uk31Fe2RVS3xEbXHGaN_z5T and looks sharp. Had it in a couple of weeks and so far so good. It’s cooling a bedroom about 25ft X 15 no problem at all.

A metering devices like a small hole. Which we call an expansion valve. The expansion valve can fail in two ways it can either stick open or it can stick closed so you can imagine either you have a small hole or the hole is clogged. If the hole is completely open then everything will be working but you won't get any high pressure or low pressure. Because the compressor has the push-and-pull against a metering device expansion valve small hole. And the other way the metering device expansion valve fails if it's stuck closed then you get a high pressure in a low pressure but you get no cooling.

Excellent info. However, you missed the a/c evaporator part too. Those also go bad and that is located deep inside of the dash. What I cannot understand is the shop I brought my vehicle may have missed this. This is after having the compressor, drier and a bunch of other parts replaced. A/C went hot again. I am waiting for the shop to tell me the verdict and tell me the evaporator is bad. In this case, the shop is fired as they should have found this the first go around. This means I will do the job myself, which I didn’t want to, and find another shop to recharge the system. My trust with shops are shot.

I had to put a new reservoir to get my vents to blow air but the front still won’t blow air. And the air that comes out the back top vents is at 90 degrees and sometimes 78 or 75. My ac has not worked for a few years.

Do you help troubleshoot? 2014 Infiniti QX60 hybrid. Only blowing hot air. The compressor was recently replaced, and the system recharged. It's still blowing hot air. When you turn the AC system on, and the compressor comes on, after a minute or two the high pressure line feels cold to the touch. No frost anywhere though. Any ideas?

@yeahboyoboy Жыл бұрын

I don't think that if you have the inconsistent A/C (which requires Freon to get cold) could be as a result of a leak for any prolonged period of time anyway as eventually the Freon would leak out (say at the expansion valve or other) and it would never get get back to being cold, correct? I had a problem w/ this inconsistent symptom, they checked for leaks, vacuum tested it, ran the dye throughm, and added a little more Freon. Shortly after going again...the symptom of inconsistency was the same...and then they wanted an additional $300 more to replace the valve...which was the symptom to begin with. I would think that while the valve could leak, having low Freon would not provide this symptom...just saying.

I’m having a similar problem. I’ll completely empty the system and when I try to fill it it’ll literally say it’s completely full after barely putting anything in. So I’m assuming there’s a blockage somewhere. Not sure if there’s a more common place to check for blockages. Any recommendations would be appreciated. Btw I’ve already checked all fuses/ relays. I also checked high side pressure switch which happened to not be closed. Thought I figured it out. Replaced that and it’s still not closing. So I’m not getting enough pressure on high side for switch to close even tho when I put gauge on it says it’s completely filled. Any info would be appreciated!

Is there a major difference between a bad compressor and bad valve?

@fluoridaman2332 10 ай бұрын

If the compressor is making noise, not engaging under full charge, leaking or has no pressure changes when engaged it's probably the compressor. On some vehicles a stuck closed expansion valve can cause a system go into a vacuum, making it seem like it's the compressor when it really is just the valve.

My standibg pressure is 120 psi. Compressor clutch works and compressor seems to try to do its job. But low side drops by a few psi and vibrates very noticeably. High side stays at 120 and vibrates but not as much. Im thinkibg blockage rather than bad compressor. Perhaps expansion valve? What do you think?edit.

The reason you might get blockages is because the pistons are still and blocking the passage. Check compressor clutch is ctually spinning that centre bolt.

@@Swenser my AC clutch doesn’t engage. I guess that would make sense why I can’t get enough pressure on high side because it can’t get by the piston in the compressor?
