Air Conditioning - Who makes Day & Night furnace/AC

I have a problem with the AC in the house we just bought. The AC blows air, but the air isn't cold. From what I can gather I should check the condenser and evaporator for dirt. The condensor is OK to check, but I cannot get the led of to check the evaporator. The unit I have is called Day & Night Deluxe Mid-efficiency gas furnace. Is there a way to get hold of a manual? I could even find out who makes it. Any suggestions?

i think that is a carrier product. how old is it?

Well, it looks like the permit was pulled in 92, so that would make it 12 years old.

I think hvac is correct and it was marketed under the Bryant label.

Thanks guys. I will contact both companies to see if I can get hold of a manual. I surfed their web sites but no links to my model. BTW, i checked and found out that niether the fan nor compressor is running. Only the inhouse fan is running. I will be checking the electricity connections next.

I'm not sure you need info from the manufacturer to solve that problem. If the outdoor unit doesn't run there are a whole bunch of things to check that are not brand specific. 240 volts to the line and load sides of the contactor and 24 volts to the coil of the contactor to start with. Once you know if you have this, you are on the trail of the problem.

the tstat, upon call for cooling will send 24 volts a/c back to the furnace. this is almost always physically tied to one of the low voltage wires going outside. after the wire leaves your furnace, it travels through:
1) a pan float switch, if in attic
2) the condensate pump safety
3) a low pressure switch outside
4) a high pressure switch outside
5) then to the contactor, pulling it in and starting the unit

you may or may not have some of the seafties, depending on the install.

look for broken low voltage wires going to the outdoor unit

do you have a meter?

Thanks. I checked the outdor power and found that I only have 1 phase (110V) instead of 2 phase (220V). The cumprit turned out to be one of the breakers was off. The other more embarressing fault was that the thremostat was programmed correctly, meaning that when I turned it on only the indoor fan would come on. After changing both these things, the AC blows cold air. Thanks for your help. This has been a first learning experience with AC.

You should change that breaker so that it's just 1. That way when it trips the whole thing trips not just one.
