04 Subaru A/C not cooling
Comments (6)Yep, a leak I put a 10 oz can in last July 3, and the system worked fine all the rest of that summer. That time the A/C was just low, not "too low" and it was still cooling, just not as much as it should. The additional (without gauge) refrigerant brought the delta Temp up to specs. The trouble shooting of no clutch engagement led me to just add another 10 oz can to see what happens. The engine was running with the A/C switch "on" and it took only 10 seconds of the fill (these cans can take up to 10 minutes to empty on a nearly full system) for the clutch to engage and about 3 or 4 minutes to empty the can. I'll let it run this way for a few days and see what happens (it is cool here in NJ right now - in low 40s this morning). If it holds for a week I'll just top off using a guage and some anti leak. If I can get the car through the hot weather of 2013 for under $50 invested, I'll take it and worry abvut next summer if the car and I are both still around. Both of "us" are Senior Citizens. Up to 2009 I had always taken my purchased new cars to a shop to have the A/C serviced. I have kept all cars purchased new for at least 10 years, the 2004 is obviously coming up on 10 years - so new car is on the possible solution list. A 1999 Mazda was my first time adding refrigerant myself, it worked out fine there too - also just added a can to increase cooling, and it worked. I traded that car in before much of a test on the pump-up, but I did keep that car through that summer that I added the refrigerant....See MoreAfter the freon leak repair
Comments (10)"It isn't the responsibility of the A/C contractor to take care of any issues with the sheetrock, waisncotting or anything else other then the refrigeration line repair though. He isn't the one who drove a nail where it doesn't belong. Unless of course he neglected to use nailer plates where necessary. " Yes, I understand, and the HVAC installer did indeed install nailer plates to avoid puncture where the baseboard is installed. I've never seen wainscotting installed which such large nails and wouldn't expect the HVAC installer to have foreseen that. He was also upset about the length of screws used on some shelving, as they nearly hit some other pipes. I was asking about where the oil had seeped into the sheetrock in case it posed some health threat. If so, I'll request that the builder have that portion of sheetrock replaced and maybe the wainscotting over it as well. The odor was evident before the tech made the repair, as soon as he opened the wall, so it doesn't seem to have anything to do with his repair work. He mentioned something about oil, and I didn't know if a lubricant was used on the copper pipe or what. I also wasn't sure if an additive is typically used to help trace freon leaks, the way natural gas has a compound added to give it a foul odor. I've had a massive headache this afternoon, which is very unusual for me, and was concerned since my dh is highly sensitive to chemical odors & has respiratory problems. The tech was pretty emphatic that I call the local gas co. to come check for possible leaks as well. An inspector from the gas company came while the tech was here and found no problems. At any rate, there was no freon in that unit at all, so it took a while for the tech to do a full charge of the system once he repaired the damaged pipe. He checked the other two units and said they're fine. Thanks for your reply....See MoreAc vents sweating
Comments (36)Don't be too negative about the rule of thumb. The best definition of the term is means a broadly applicable approximation. While no one should size anything in an HVAC system, a number such as this for a particular climate can serve as a very useful reality check for the real calculations. I try to teach this to new bench scientists all the time. For example, if they are planning an experiment that requires them to put something we've grown into a different size/format "container" at a much lower density. There are a lot of other things that feed into the final configuration too. It is relatively easy to come up with something that does not look right when you get out of the weeds and look at it from a distance. I'm in the position to look at it from distance when we go over their plan. In this case, if someone in a climate where something closer to 400 usually works, comes up with 300 or 500 sq/ton the thing to do would be to look for the cause of the deviation or check the calculations for a mistake....See MoreAdding heat banks to electric furnace.
Comments (23)His thought was the amount of money it would cost to repair what I have and upgrade to make it adequate for the size of my house would likely be $1000.00 at the minimum and likely more. He didn't think it was worth putting that kind of money into my system that is undersized and not really heating adequately to begin with. He just said if it was him he would run it in emergency heat for now if I was going to replace the system in the spring. The extra cost of emergency heat would be cheaper then "fixing" it right now if I was going to replace it in the spring. If I could get it completely fixed for a decent price then he thought I should fix it and not run emergency heat. He just doesn't think I will be able to get someone to find the leak, fix it, refill with R22 for a price that is worth it. I am getting some estimates just to see....See Moremr_havac
