Hello from KOOLBREEZES, this is a simle problem and easy to fix. You have 2-lines going to / from your outside unit. a SMALL COPPER -line and a LARGE COPPER line with insulations. The fat line is suppose to have moisture on it wheres it,s not insulated which tells you you have enough refrigerant gas comming back to he compressor but if its dry you,re low on freon and need a charge or the outside condenser is dirty and not getting rid of enough heat!

    OK, forget step 4 (cleanning the condenser coil for now) and lets go to step 2--3. Checking the indoor airflow across the indoor coil. this unit is designed to have a certain cfm per minutes across the indoor coil when clean and running right. Now, here' the problem. Low air flow caused by dirty filter, dirty fan blades,and last plugged inside a-coil. Check the airflow out the farthest vent from the unit, which they all should be close to the same cfms. If the farthest vent has a marked less airflow, then your problem is low air flow first ...2ond , clean the condenser coil with high preassure,(put your thumb on the end of the water hose .when in doubt, call 918-360-9272 or email koolbreezeshadiagnostic.smrated.com.

My thomastate for ac is showing a flashing snowflake and will not make the ac work how to reset it


The snow flake indicates that the mode is set for cooling, not hearing our both heating and cooling.
There should be two temperatures given by the thermostat, one is the actual room temperature and the other is the temperature setting. The room temperature reading only changes with room temperature change. The thermostat setting temperature changes when the up or down button is pressed.
If your room temperature, say it it's 80° and the temperature is set lower than 80° with a snowflake, the fan should run and start blowing cool/cold air. If you system does not do this, then there is a problem. The problem can be the fan housing cover is not making contact due to the cover not installed properly, nothing will run in this case, no fan. It can be there is no power delivered to the indoor fan, or to the outdoor fan, both these fans must run during thermostat calling for cooling.
The thermostat is not something to be reset as you asked but rather, you check that both fans run and that the outdoor fan makes compressor noise.
Come back with your findings or call a service person. One last try is to shut power to both indoor and outdoor parts of the system and then restore power in attempts to reset the unit or power circuit breakers

Thermostat does not reach programmed temperature


Have you checked with a thermometer to see if the area is reaching the temp you have it set at? A thermostat has nothing to do with the temp in your house. If you have it set at a temp for Example ( 72 ) and it is not reaching that temp to shut off then you have a problem with your unit or insulation in house. If you set stat on cool at 72 and the house gets down lower than 72 then there is a problem with stat.

Why can't I lower my honeywell 8500 below 67 on cool?


With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed

How can I make the ac quieter inside the house?


If you have hard ducts, you can use some flex duct between the supply plenum and the hard ducts as a way to quiet the noise down.

My condensor fan and compressor on my Carrier AC (Model# 38ckc036350) stopped working, so I replaced my capacitor and they both work fine now. The problem is my house won't cool down. There is c


Often after a repair has been made, the air conditioner will take hours to readjust back to normal. When the system has been off for to long, not only does the heat in the house rise, but so does the humidity, which has to be pulled out of the air first before it really starts dropping in temp. You could have a low charge on refrigerant, dirty filters, etc. More than once I have ran into things that were just coincidence after a repair that showed up. Since you just replaced the capacitor, I would make sure the fan motor is turning in the right direction and there is nice air flow coming out of the condenser, some times if one wire is wrong, it can cause it to spin backwards, which will work, but just barely. The air needs to be pulled through the coils, not pushed. Hope this helps!

I think my goodman refrigerated air system may iced up. How do I know and how do I thaw it so I can cool my house


Hello, usually the suction line will begin to ice up ( the pipe with insulation on it) if there is a airflow problem or a low refrigerant charge, to thaw it out just turn off the ac and set the thermostat to fan. Now the unit will need to be serviced because if it keeps running this way the compressor can get severly damaged.

My furnace wont come on unless you turn it down then back up again. Its set at 72..but you have to turn it down then it will heat up..and you have to keep doing this unless you want to freeze!


The first thing I would do is change the thermostat and go with the least expensive manual heating cooling stat I could find and see if that helps,Thank you

We have a3 yr old Goodman CAPF3030B6AA Airconditioner and Furnace. The Air conditioner hasnt worked right all summer. Its 102 degrees outside and we can set the thermostat on 72 degrees and it will be...


A/C units have a design temperature of 90F. Now when the temperature is above 90F they start to have trouble keeping up. Depending on how well your unit is sized for the house, you will notice when the temp is over 90F. I don't know if who ever looked at your unit checked the refrigerant pressures since you said he checked the temps but I assume he did, however, it could possibly need charging.
