Is C. baccatum OK in cool summer areas?
Comments (6)My overwintering C. pubescens recently took off with a flush of new growth as the light (coming in through the window) increased in intensity and time. The house is seldom (like almost never) over 70 F during the winter and mostly between 60-68 F. This species has done much better in the house in the cool temps and low northern winter light than any of the others. It has many buds now without any artificial lighting. Unfortunately, I can't report on C. baccatum. Mine suffered problems unrelated to cold or light :( and does not look like it will be around for another season....See More04 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 MoreNew window unit a/c not cool enough?
Comments (11)It was installed yesterday around noon. Temp outside was probably about 80 degrees and humid. We set it somewhere in the 70s and left it running for a few hours while we went out. When we got back, it was running well and the air seemed drier in the room but what was blowing out of the unit didn't feel that cold. I should add that this is in an apartment that we rent out. We had to leave, so we turned it down to the lowest setting, 60 degrees, and left it running. We called the tenant and asked her to call us and tell us whether it was working properly by the time she got home from work. From what she said, it sounded like it wasn't any different. We live an another city, so it's a bit difficult for us to get back up there to check on it. The apartment is a small studio, and it's a 7800 BTU Friedrich, so I believe it's the correct size. We had the store install it. I suppose we would need to use a separate thermometer to determine whether the room air is cooling to the right temperature, but subjectively, it didn't seem like it was....See MoreNew heat pumps cool well but we need heat
Comments (11)tigerdunes - I have learned a lot from reading your postings on this forum and I appreciate your inputs. Your minimum specs list has already been very useful (though a lot of sales people really struggle to find answers about some of the items on that list), and IâÂÂm leaning now toward the XL15i instead of the $660 more expensive XL16i. I still havenâÂÂt completely ruled out Carrier and Rheem, but a neighbor has had a 4-ton Trane XL14i for over three years and I like the way it does not seem to have collected very many of the evergreen needles that are everywhere around here. I am curious though just why the XL16i has so much trouble with dehumidification, and whether that is important to our well-shaded house just outside of Seattle. We havenâÂÂt bothered to run our heat pump in cooling mode for at least the last decade, so I remain mostly concerned with heating performance and expect to use very little cooling. Also, is the XL16i any less reliable that the XL15i, or is it just (as I understand from other forum postings) that it is more complex to hook up and hence more prone to improper installation? I am also puzzled when I compare ARI heating performance of the XL15i and XL16i. At 47 degrees their ARI heat capacity and COP are identical, and at 17 degrees the 15i has only 1% more heat capacity. The 16i has the better 17 degree COP, 2.86 versus 2.82, but it falls down on HSPF to 8.50 versus 9.00 for the 15i. This seems to imply that the 16i spends more time in defrost mode, but I do not understand why. Returning of your spec list, I assume âÂÂstaged backup heat stripsâ refers to the capability to selectively turn on part instead of all of the backup heat? Our old heat pump has this feature, but I have yet to find a sales person who can tell be whether modern systems can do this. One issue is not really relevant until our new heat pump is being installed, but opinions about it are so amusingly diverse I cannot resist asking. Our power utility offers an extra rebate if we install a lockout control. What should it control? We have a lockout set at 32 degrees on our old heat pump and I understood it prevents the backup heat from coming unless the outdoor temperatures is below 32 degrees. The âÂÂenergy expertâ I talked to at our power company agreed, but said the lockout should also turn off the heat pump compressor at 32 degrees to âÂÂprevent a spike in our electric bill.â I recognize efficiency is down at that temperature, but unless there is a lot of icing up it still seems to make sense to run the compressor. Sale personnel were about evenly split whether the lockout should turn off the compressor. Is there any clear answer on this?...See MoreEdbishop868
