Question about Heating & Cooling

1 Answer

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 80-85 degrees in the house. We had the guy who put in come out about a month ago. He changed the filter and hosed off the coils and said all temp readings were fine. Its not fine! It doesnt even remotely start getting cool until sometime in the night but only gets down to about 74 degrees! Help!

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.

Hello my name is Heath it will be my pleasure to assist you. First thing to do is go to the furnace take off the lower blower door and locate the circuit board turn the power off to the furnace. In the circuit board there should ba a small car like fuse usually 3 or 5 amps check the fuse it is probably blown replace the fuse with the same amperage fuse and then turn the power back on on the furnace and check the operation of the furnace.

Just cut on 8 year old Goodman CPLE24-1 AC for the summer. Ran 8 hours fine, Next morning noticed outside unit running, very little cool air blowing out of inside floor vents (like the blower fan was...


Due to the many different questions I see about Air Conditioning, I am including this overview to help us better understand each other for trouble shooting. A basic air conditioning system has a Thermostat, Air Handler or Furnace Fan and a Condensing unit. In a split system, the condensing unit (Condenser) is separate from the furnace and usually in the back yard. When working properly, it blows hot air. It connects to the cooling part of the system by 2 copper lines. One large line and 1 small line. The part that cools the house is the "Evaporator" and is usually on top of the furnace inside the square metal box (Plenum). When the Air Conditioner is running, the large copper line should be cold and the smaller line should be warm. Common signs of low refrigerant are that both lines are the same temperature and/or frost or ice has built up on the large line at the condenser. The thermostat will normally display room temperature on till it is touched to change the setting. It could have a "Span" setting as well as times and temperatures. The operating "span" of MOST residential thermostats is 40 to 90 degrees. That means you can set it as low as 40 degrees and no higher than 90 degrees. It probably has a fan switch also. When in the "ON" position, the fan will run constantly, 24 / 7, but the condenser will still cycle on and off as needed to keep the house at set point. If you have a suggestion to include in this paragraph, please let me know.

I think I have it covered above. Let me know if you need something more specific. Thank you. Roger

I need the venting specifications for CAPF3030B6AA furnace that the city inspector is asking for. Do you now where i may get it?


Adhiinc, the model you posted is for an AC coil made by Goodman. You will need to post the Make and Model number for the air handler/furnace that this is connected too. You can find the model number if you remove the front panel and look on one of the sides for a label. Thanks and good luck!

I have a 2 1/2 ton unit. If the outside temperature is 95 degrees. What should I expect from my unit in cooling my house.


If properly charged your unit should perform fine, having a dirty condensor at that temperature can cause problems not easily recognized.

A well insulated house should be able to maintain a 20 degree temperature difference whether its summer
or winter. No Mechanical cooling or heating involved
for at least 6-8hrs if not more.

If it never cools when it is 95 degrees outside the ambient outside temperature is not the problem.
At 95 degree out side air you should be seeing inside discharge air temperatures betwenn 48-55 degrees.

It is the load in the house that determines how long the unit will run at 95 degress.

Do i need to turn a switch on or off on my goodman unit or the furnace? how do i prep for the summer with out calling a tech?


There are no switches other than the breaker and outdoor disconnect that need to be on. Change your filter in the furnace. I would take a hose to the outdoor coil on the condenser to clean out any dirt and leaves on the coils. Do not spray on high pressure. Just get a good light pressure and spreay from top to botton perpindicular to the fins and up at a 45 degree angle. Other than that, set the thermostat to cool and you should be good to go.
