I would like to get back on line if at all possible. Just got done replacing the valve plate for the compressor. started up and check operation about a week ago. all was good. It has a CPR valve on it. I'm thinking this is leaking by and not holding pressure back.
Any ideas on freeing up the Copeland compressor. Let me know. If i have to replace I will have to.

I've been lurking for a couple of weeks and have had a number of contractors come over to give an estimate on replacing my 20 year old system. I had two paths to go: (1) Upgrade to a fancy future-proof system or (2) Replace system with a standard modern system. I live in Orange County in Southern California, so path 1 just didn't make sense overall given the relatively short usage of the AC and furnace throughout the year.

I live in a 1,900 sqft 3-story townhouse. The AC is outside and furnace in the attic. I've narrowed down my selection to Trane to AC: 4 ton XB13 or XR13 and furance: XR80 or XL80. None of the contractors could give me any functional differences between the XB13 and XR13 other than the shell being different colors. The website also noted the XB13 being 48,000 BTU while the XR13 was 46,500. This was explained as the XR13 being more efficient. The XR13 also has a bit more insulation to give it a minor 2db difference in sound. These three features wouldn't justify the ~$350 difference, so I'm wondering if you guys would be able to help me understand the differences. As for the furnace, there's a ~$250 difference between the XR80 and XL80. I'm less informed about the differences and benefits of one over the other in this front.

Also, given Trane = American Standard, I'm still open to it if the price difference is noticeable; however, I can't seem to find the exact answers I'm looking for as far as actual differences. Given the lower-end models I'm selecting, would the comparable AS models offer the same warranty? Also, I've read and have been told Trane and AS comparable units are the exact same thing with the same model # sans the brand in its nomenclature. One contractor though, has told me AS does use slightly inferior parts in its units.

Overall, I'd love to hear any thoughts or suggestions in regards to the Trane models I've inquired about and the American Standard equivalents, if the cost difference justifies any differences in warranty and "parts quality." Thank you, and I'd really appreciate any input to help me make my final decision this week. ]]> AOP Residential HVAC AlX Boi http://hvac-talk.com/vbb/showthread.php?1335711-Trane-AC-furnace-model-selection Munchkin boiler 8 pulse fault code. http://hvac-talk.com/vbb/showthread.php?1335701-Munchkin-boiler-8-pulse-fault-code&goto=newpost Wed, 19 Jun 2013 03:05:56 GMT A lady from our church had a munchkin model #80m boiler put in 12 years ago.

She said it has had the same problem since day 1. System tries to fire but then locks out on 8 pulse code: air press. switch fault/stuck closed. I have not worked on boilers but told her I would look in case something obvious. When I got there, she handed me two press. switches that had previously been replaced by boiler experts. Both were still good! The induced draft blower had been replaced, the vents were checked for blockage, serviced annually. The experts told her they just don't know anymore. I noticed some burned off resistors on the board and the customer said they had a power outtage and he had to reset the breaker and heard a "pop." He says the only thing that hasn't been replaced is the board. The board is a problem but maybe not necessarily the problem because he said it has had the same fault code for a long time before the power outtage. The current press. switch is closing once the inducer kicks on but at what in. wc. I don't know. The customer says if he resets the service switch and then puts his finger over the negative side of the press. switch, the boiler does fire until the next heating cycle. I'm not a "parts changer" type, I've been in the field for 10 yrs. and a tech for maybe 4, but no boiler background, I'm just trying to help out with all their frustration with past experts. Any advice would be greatly appreciated.

so the system is a McQuay split ac with hotgas in the evap. this morning when I arrived the system was running I observed the oil level and it was a bit low maybe just under 1/4 sight glass. there was a lot of foaming in the glass so wasn't the easiest to tell. there is no oil separator and there is evidence of oil on the drier. im a little nervous about slamming oil into this system as it has a long line set and im worried a slug will smash the valves. I also checked the oil pressure at 110 and suction at 85, and discharge is around 200 with r22

any advice on a safe way to proceed would be great. obviously I haven't provided a huge amount of info to you guys but I don't have much lol as I haven't look to hard at it but I will be ]]> AOP Commercial HVAC warhog61 http://hvac-talk.com/vbb/showthread.php?1335691-oil-failure-on-6d-copeland-comp What is the best flaring and or swaging tool? http://hvac-talk.com/vbb/showthread.php?1335681-What-is-the-best-flaring-and-or-swaging-tool&goto=newpost Wed, 19 Jun 2013 02:50:46 GMT Hey everyone, I'm looking to get a new flaring tool and am wondering what you guys think is the best one.
