I have a carrier unit that is about 12 years old. We had a digital carrier thermostat when we bought the house. Well, to help save money and environment we wanted to get a programmable thermostat. We purchased a hunter 44360 from Lowe's. Upon the installation, the old thermostat had 5 wires as shown in this picture:

I have put the color of the wires that were there before we changed anything.
R=red wire
Y/Y2=yellow wire
G=green wire
C=brown wire
W/W1= white/beige wire

Here is the hunter connections:

According the manuel if I did it right, here is how I connected them:
G=Green Wire (G)
RH=red wire (R)
W/B=white/beige (W/W1)
Y1=yellow wire(Y/Y2)

In the manual it said:

Do not connect a common wire (sometimes labeled "C") to any terminal on this thermostat. Tape up the wire and do not use. This wire provides electicirty to non-battery powered thermostats.

The brown wire was connected to c so I taped it up and did not use it on the new thermostat.

So my question is, did I hook this up properly?

I am having some issues with the a/c unit now but I am not sure if it is related to the wiring. So the a/c stays on and blows cold air through vents but it seems like its not blowing much air through and it is not cooling the house down enough. The a/c will stay on and try to cool but being unsuccessful. The thermostat is currently set at 70 and it is 79 in the house. The unit is not frozen but it has frozen in the past. The coils were cleaned 2 months ago by a service tech which cost me $150 and I do not want to pay for another visit. I do not know much about the a/c units but I am quickly learning. The reason I think it might have to do with the wiring is because I am not sure if something (either compressor or condensor) may not be functioning correctly. If anyone could provide any helpful solutions I would greatly appreciate. Sorry for the long post but I tried to be as detailed as possible.

I do not believe you have a thermostat problem. Your problem is somewhere in the equipment.
Check the furnace air filter.
Check for any obstruction in the return air.
Check for any loose paper (wiring diagram) stuck in the blower assembly.

Well, I thought I had done the wiring correctly but wanted some second opinions on it. After I posted the message last night, the a/c eventually cooled down to 70 through the night. Maybe the sun is to hot for the a/c unit and it can't cool correctly until the temperature drops??

I did turn it off and turn it back to see if it would increase in power. I don't think that helped or changed anything.

I know the unit is fairly old, but we want it to last as long as it can before replacing. We did change the filter just in-case it was to dirty which might have solved the problem. We will see when I get home today. I am curious to know if the freon lvl is low or not. Is there anything that I can do to check the lvl? It cools and sometimes freezes up so I know its not empty.

Any other suggestions on how why it would freeze so much. I know for a fact the coils are clean.

The Freon (refrigerant) level has to be checked by a qualified HVASC service person. Unless you have gauges specifically designed for that type of refrigerant,temp probes,and the knowledge to use them. If not call for professional on site help.
