H****J 发帖数: 22 | 1 请imore 给参考,是否要换新的系统了。谢谢!
症状: AC 制冷效果不好。今年夏天温度高且持久;室外 90F;空调持续开,只能将1楼
和地下室的温度维持在77F左右。 晚上将空调设置到二楼,需一个小时左右才能将温度
降到75F左右。前年ac加了近1 lb 的ferran; 去年气候不是很热,空调制冷马马虎虎。
冬天室外20F, furnace will turn on every 10 to 15 min;

n***s 发帖数: 10056 | 2 能不能加些带染料的冷媒。看看哪里漏。说不定可以补漏。 |
w*****m 发帖数: 20421 | 3 楼上楼下都要一起开吧,你只开楼上或者楼下,效果当然不好
FURNACE没有什么技术含量,空调还是出风口的问题看看是不是
够凉 |
i***e 发帖数: 9429 | 4 如果要换的话,建议你4和2之间做选择,灰常不建议你上超高端机子,因为人工只有一
年保证,这完全是扯蛋。选1和2的话你还需要10年的人工保证,不然一年后如出现故障
,你绝对会哭。
我蛮同意雪妈和noles, 你的空调不像有大问题,关键是要找对师傅,检测和维修到位
。 |

有个帖子说, 空调evaporator 有filter, 而且需要换.我的空调只有进风口有filter. |
H****J 发帖数: 22 | 6 Imore 请看看下面的组合是否合理;
请参考首帖;
#3 furnace + #2 AC
AC: xc16- 4 ton 2 stage a/c unit model - XC16-048-230;
matching cased coil model - cx35-49c;
Furnace: 2 stage 96% 110,000BTU gas
furnace power saver motor model -EL296UH110XE60C;
根据你的经验, 价格应该比#2 便宜多少; 性价比是否更合理;
谢谢

s*******3 发帖数: 52 | 7 你的情况跟我很象,不过我的是5吨空调,140,000btu furnace,同样的#4,我得到的
报价是:
$7600。 14acx + EL195UH135 + coil + permit(200)= $7600
如果是 13acx + ML180UH135 + coil + permit= $5800
我的师傅很不建议 he 机器,他说省电费没有那么多,但是部件要多,所以出故障的概
率高,还有维修费用很贵。他说,譬如普通空调机 motor坏了,换一个400, he 的换
要1400。 |
s*******3 发帖数: 52 | 8 我这些日子做的research,2 stage furnace 对大房子并不是很有用。我现在的1
stage furnace 从来没觉得不舒服。不过,东西越复杂,就越容易出问题,这还是正确
的。
我的理解是:大房子,很多出气口的,1 stage 出热气的时候,不觉的风很大,吹的不
舒服,如果小屋子,大风呼呼吹,是不好受些吧。又有说,2 stage run 的时间长,那
么风被过滤的多些,这个我不是很认同,小风长时间,跟大风短时间有多大区别?不过2
stage 是提高效率的方式,似乎是这样,但是提高这样一点点,相对成本(现在的投入
和将来的维修)有必要吗? |

1 hour dropping from 90 to 75, it does not sound bad at all!
to tell if it is working fine or not, use a thermometer, measure the
temperature at the intake of the vent and the outlet of the AC, a
temperature difference between 14-20F is considered normal. A good unit can
generate a temperature difference of 20F.
consider cleaning the evaporator (the unit in your basement or attic) and
the condenser coil (the metal fins around your condenser fan in the outdoor
unit). I did it for both of my AC units, it was not difficult.
Cleaning the condenser coil was really straightforward, just use a garden
hose to spray the coil directly to wash out the dust. The evaporator took a
bit more time, because I had to clean the mold first.
you may also replace the dirty filter (both in the inlet and the evaporator
filter, some evaporator filters are washable, like mine).
