Due to EPA regulations and the complex tools and equipment, I will suggest that you call a EPA licensed technician to do this job. The following is the basic outline of what will be required of this technician.

To install the TXV valve, all of the freon must be recovered from the system. The copper lineset at the indoor unit will then need to be cut open. Since the lines are no longer sealed and have been exposed to the air, filter dryers(s) should be brazed in. After the TXV is brazed in, the system needs to be placed into a vacuum per EPA (to verify no leaks). At that point the old refrigerant may be put back in to the system if it is still OK..

The hard start is really unrelated to the TXV operation. It is not necessary to do this job. Although it does not hurt to install one. Basically the hard start will lower the start/run amperage of the compressor. These are usually used in a "tight" compressor scenarios.

I hope this helps:)

If the person who does this is not licensed by the EPA, the penalties could be horrific. Be warned.

Have and older model. 1.5ton 10 seer unit. The


a hard start is not for a fan they are for a compressor and if your compressor need a hard start kit it most likely is not long for this world. most manufactures have a 14 seer line (13 is min) that will with the right coil and furnace match get a 16 seer rating if you have the money this is a good way to go if it is just the fan thats not working i would call another service company or ask that another tech be sent out because if they are telling you that you need a hard start on a fan they dont know what they are doing

I just installed a GSC140421 using a coil CAPF


hey there, the matching coil for your unit is a Model# CAPF4860C6A. The coil you have installed is a 13 seer where the condenser is a 14 seer. Myy guess at this point without being there is you have a hot house (80 psi suction) while eliminating more heat from the condenser (180 psi). I am also guessing you are using r-22? If you could post your super heat and subcool readings and if ou have a txv or fixed orifice (guessing txv?) I could help you pinpoint the problem.

Over heating compressor


The seer rating is not what you should be concerned about. You have to be sure that the condensing unit matches the evap BTU ratings. If the evap is too small, it acts as a restriction to the system. Low back pressure, which is inadiquate return freon flow, will cause the compressor to over heat.
Hope this helps

If installing a GSC140481 condensor with a ARUF486016 air handler is it necessary to change the txv to increase energy efficiency? Can these 2 units acheive a 14 SEER rating?


The real question is, am I going to get 14 seer using the old coil with the new condencer.If it is using r-22 then the old txv should work,but the old coil is proboby rated at 10 seer . since these were never tested together you would probobly see a minimal gain in efficency.Now if it is a matched set(ahri rated) you with definently get you 14 seer.Hope that helps!

I just had a bryant a/c installed (txv) should it have a hard start kit as well.


Anytime you have TXV they do need a hard start kit. The TXV shut down on the off cycle and does not allow unit to equalize. Rusty

My goodman heat pump has frozen up 3-4 times already this summer. It is a dual system 10 seer (i believe are the terms). Every time someone comes out they can't figure it out because the system is...


After system has been running 10-15 minutes, the discharge air temp should be 18-22 degrees colder than the air being sucked in. If the air is more than 22 degrees colder then the problem is with air flow. Check filters, blower speed, make sure all vents are open, is indoor coil clean. If the discharge temperature is less than 18 colder, then the problem is with the refrigerant portion of the system (low charge, improper flow control of freon into coil) the key is if you have an orfice or a TXV (Thermal Expansion Valve) to control the flow of refrigerant into the coil. TXV's are known to fail with intermittant problems, however, most 10 seer systems do not use a TXV, they use and orfice which could have debris in it affecting the flow of freon. Hope this helps. When you rate my solution, please keep in mind that I am a technician that normally diagnoses equipment by checking it out in person. I do the best that I can with the information that you provide me on Fix-Ya.

Thank You,
Chillmaster

We installed a 4 ton downflow coleman air handler with evap coil Model number 1854s2m we did not change out the outside unit. the outside unit is a 13 year old 3 1/2 ton intertherm condenser the system is...


you have a missmatched system, for it to work try removing the orfice on the high side txv it is not allowing the evaperator coil to fill with refrigerant properly coleman and intertherm dont like each other since they control a large market in the manufactured housing heating and cooling units electricaly connecting the componets together no issue prefromance sometimes is the issue hope this helps
