Unit runs but will not cool. Followed troubleshooting diections in manual with no luck. Wondering if there is a refridgerant recharge path which is not in the manual

recharging with gas will not be in the manual as it is done using pressure gauges and is a job for an experienced refrigeration technician
call one in as it may not be a gas problem but compressor not running or a blocked tx valve

Can a fedders air conditioner A7Y15F2A-E be recharged?

Hello, anytime the unit does not blow out cool air I like to start with checking the airflow, check the filter and the evaporator coil for a buildup of dirt. If that check out ok then either the unit has a refrigerant leak or the compressor is not operating if the compressor is running than the unit is low on refrigersnt and can be recharged. In order to recharge the unit a piercing valve must be installed on the low side of the system, most window units do not have valves so one must be added to be able to charge the unit.

Window unit is freezing up and it does not cool the room

Ths is usually caused by the air intake filter being dirty or clogged. Remove the filter and clean as necessary. If that doesn't solve the problem, there may be a small leak in the refrigerant coils. In which case, replacing the coils will be required and the compressor will have to be recharged with refrigerant gas.

Hope this helped you and thanks for choosing FixYa.

Hello. I have a Bryant 561CJ030-D AC unit. The fan comes on but doesn't seem to be cooling. We have had record high temps the past couple of weeks (over 100 degrees), and I'm wondering if the...

Is the compressor turning on? The fan may be running, but you will not get cooling effect unless the compressor is circulating refrigerant. It appears your unit is a 2.5 ton unit. What is the square footage of the space being cooled? Is the space insulated?

AC was working perfect before we moved recently. Now it's cooling is very slow? I wonder y?

Depending on how is was placed (Upright, on it's back, or lying flat, as if it was installed) could be the problem. If it was not lying in the same position, as it would be installed, the refrigerant gas ran back into the inner reaches of the compressor and has not returned to where it needs to be.This is usually referenced in the Owners Manual, prior to it being installed the first time. It probably said something to the effect of "allow the unit to sit in the installed position for 8 hours prior to operation". This would allow the refrigerant gas to settle back into place, as well as the oil lubricant in the compressor.

M best advice (Hopefully it's not to late), is turn the unit off for at least 6 hours, to see if everything will settle back into place. If that doesn't solve the problem, you will need to have the compressor professionally recharged. As the existing refrigerant gas will have to be evacuated and captured, before recharging.

Hope this helped you.

My ac is not blowing air as cold as it was can i recharge it with freon?

It may or may not need recharging with freon (freon is no longer legal to use). So before you attempt to recharge it or have it recharged, troubleshoot the following:

1. The air intake filter may be dirty or clogged. Remove and clean or replace it.

2. The cooling coils may have a buildup of dust and dirt. Clean the with warm water and a mild dish
washing detergent. After drying the coils, put a light coating of WD40 on them.

3. Cooling fins are dirty and need to be cleaned. Like a refrigerator, if the fins are dirty the unit has
to strain to cool. A vacuum cleaner and an old tooth brush work well ro clean the fins.

4. If the unit is in direct sun light for 6 hours or more per day, consider installing an awning over it.

Now, if none of the above increases the cooling output, consider having the unit recharged with 134a Refrigerant. This is best left to the pros, as it requires specialized equipment to not only test to see if really needs recharging. And if does, the equipment to evacuate the remaining Freon in accordance with EPA Regulations.

Hope this helps you to further troubleshoot and solve the problem. Please let me know. Thanks.

start by checking the air filter and clean if dirty, also I would recommnd spraying a coil cleaner on the evaporator coil and clean it. If the unit appears clean then most likely the unit has a leak and will need to be recharged with refrigerant.
