AC is running but not cooling the house. It is a Payne unit. Changed the filter but didn't help.

replace the thermostat

The difference is the sticker on the outside of the unit and the slightly higher price for parts on the Bryant. Go with the Rheem but don't be mad at me when it breaks down, the Bryant will too. Honestly it's luck!!!

The breather hose should run to the air cleaner housing or intake tube.
Check your radiator cooling fan. If it isn't working the car will run hot at slow speeds or idle then cool down after you get going faster. A quick check would be to turn the AC on and see if the fan comes on. If not try lightly tapping on the cooling fan motor with a wooden broom handle. If it comes on then you have a bad motor.
If the fan comes on with the AC then check to see if the fan comes on after the engine gets hot. If the engine temp doesn't kick it on then the temperature sensor might be bad.
If the fan is ok please post more info on your problem

Check you fuel cap. The vent probably plugged.

Yes what you say is right try home depot ,canadain tire, lowes, they all do filters with differant sizes you can get them in 12 , 10 what ever you need

Honestly, repairing and 8 year old AC unit (assuming parts are still available) can cost almost as much as buying a new one. If this is the first time you've had a real problem with it ... You've gotten your monies worth over the past 8 years. But, the decision is yours to make.

Thanks for choosing FixYa.

Dan is this a new system, or has some work on the system (to include the thermostat) been done recently?

Sounds like the thermostat may be wired wrong. From what you describe, the igniter element is coming on, as though you are calling for heating. Do you allow the ignitor to keep going and see if the gas fires off, or are you seeing this and shutting down the system immediately?

If you had the t-stat changed recently, or this is a new system, contact the installing contractor. It may be under warranty.

Most likey cooling fins are plugged and also my need new compressor or low on refrigerant or refrigerant oil. Could also have plugged intake filters in the intake.

No, Payne is a cheap Carrier unit. Keep track of your wires and what terminals they are attached to. Usually, units are either a 4 wire or 5 wire setup. In either of these the R terminal is your 24v power, G term is your fan, W is your heat, and Y is your cool. Some times there is a 5 wire which is your common. You use a common if your thermostat isn't powered by a battery. On the R terminal, they are usually marked RC/RH and have a jumper between them. The only time you should remove the jumper is in a 5 wire set up. RC refers to the common and RH refers to Hot or power. Make sure that when you are installing the new tstat there is usually a very small switch that you change for either an electric unit or a gas unit. Change according to what you have. As long as you keep track of your colors and terminals on your old tstat, you won't have to open up your unit to see where the wires are terminating. Good luck to you!
