so the capacitor will be in the conpressor box outside or the one in the attic.i just had a problem with my air compressor in the garage it was the starting capacitor.also there is a box of small glass fuses on the unit in the attic,i am a new owner of the place
Ok I will get back to you tomorrow when I change it thanks
OK PUT IN STARTER CAPACITOR.DOES NOTHING PUSH BUTTON SIDE OF UNIT TO RUN IT FOR 2 MINUTES.BUT THE LINES GOT NOT HOT HIGH SIDE OR COLD LOW SIDE.LOOKS LIKE A LEAK FREON LOW.BUT IT HAS 427-A FREON RETRO FIT ,AN I AM GUESSING A LEAK BECAUSE IT IS LOW
What push button is this? The push button on the contactor?Please let me know so that we can continue.RegardsSteve
the push button next to the capacitor .there is 427-a in there an it is low can we put in 410-a in its place.will it match up it seems to have a leak in the sharder valve,having trouble finding 427-a
Ok, I'm not quite following your dialog. I am going to opt out of this question which will allow other experts to chime in.
Hello, my name is XXXXX XXXXX I will assist you today
do i need to flush out the system or just drain out the 427 oil anthen put in 410.or should i just try to get 427-a
great which one can i get beside 427-a is there another one i can use that i can find easier
ok i will look for that stuff asn get right back to you.thank you
i found 427-a ,i am picking it up now i don,t need any special gauges for thos gas do i my ac guy is worried about that
ok oner last question i put in 417-a got pressure at 75 low side 200 high but it come out at 68 degrees from the vents should it be lower,an what can i do to make it more efficient
The air out the vents should be 17-20 degrees lower than the room temperature, or the air temperature entering the filter.
Are you using R-417 or R-427?
427-a the house temp is 84 the vent temp 68
it is cool but not sweating i will add a little more 427a
it is not sweating just cold but with air on the temp is climbing during the day when i got there at 12 it was 79 inside then it climbed to 82 by 5 with the ac running
Did you try adding refrigerant? What is the low side pressure and the suction line temperature? I will be out for a while, possibly we can continue this in the morning.
the low side is 75 the high side is 200.my problem now to me seems to be when it comes oput of the ducts it is only 69 degrees,back home in new jersey my air comes out of the ducts at 59 degrees during the day an 56 in the evening.the best i get here in savannah is 69.even in the evening
i will check the temp drop at difference time of the day,an the pressures at different time of the day,an i will look up what kind of metering device ,it is 427-a i put in .i do not no how to check the suction line temp.so you need to no what my system is unit in attic is 18 years old unit outside is 3.i will get back to you tonight
ok i will get a thermometer an check the temp,also i think it has a real slow leak
well i put more freon in it come out of the vents around 59 degrees but the low pressuere is 90
okay i will rate you today i open up the evaporator an it was loaded up with alot of debri an dirt.so what is the best way to clean the fins .the suction line is sweating. i cleaned the evaporsator a little the temp is coming out of duct at 59 degrees,so hopefully when i clean it ,it will get even better. an i got low side 80 hi side 210
You can brush the face of the coil to get the heavy stuff built up. Then you can purchase pressurized cans of evaporator coil cleaner to help with the dirt build up inside the coil. You should be able to shine a light through the coil and see the light on the opposite side. Sometimes you can't get one clean in place and the coil has to be removed, taken outside and flushed out good with water hose. Be sure to tape up refrigerant lines if you remove the coil to keep water out of the coil.
Once the coil is cleaned, the refrigerant pressures will actually rise. You may need to adjust refrigerant accordingly. This will also help with the suction line temperature being too cold.
Thank you for the positive rating. The link above shows a cleaner you can use and should be able to get locally. If I can assist you further, please let me know.
Thanks again, Ron
