EXM36F19A1 appears to be a 3 ton unit or 36000 BTU unit. How many square feet of living space are you trying to cool?

got in touch with an aircore tech he said that the new unit outside which doesn't have a restrictor in the small line valve like the origanal comfort maker had doesn't matter as far the the temp of air goes. that clears that question up. i took off side cover in attic unit made sure the sensing bulb was tight on the big line. it's positioned at the two o clock position. the instalation manual that came with the the arcoair unit shows an illustration of the sensing bulb at either the 4 oclock or 8oclock position. this from the instructions showing the instalation of a trx valve in the attic unit  if it didn't already have atrx valve . could this make a difference. should i change the position of the sensing bulb ?

If it is out of place how is it going to work right?Did you tell the installer you believe it is out of place?

Might be doing more harm than good. Get a guy that works on your brand out there.

The txv position is OK on your unit. The refrigerant charge must be adjusted using the super heat/subcool method.

Thanks Jumpy; been trying to tell him that all along. He needs to get somebody out there to fine tune that puppy.

thank you guys so much for your worldly advice. i'll not change the position of the sensing bulb. forgot you said to get someone to fine tune this unit. sofor now it's keeping the house a lot cooler than outside.because of the cost i'll hold of on calling someone. so i'll be closing this post for now. i'll surely post again if i call a tech . thank's again .
