Who's the best air conditioning guy in San Antonio?

My poor dear Wild Card, you now know why knowledgeable ac techs no longer respond to ac questions on this forum. DIAL-Charge and supercool...lol.

I havnt seen a dial a charge in 20yrs...have advanced a bit I say.

I disagree with you. As an Industrial AC tech and 20yrs in the field a rv unit is a cool summer breeze with a cold beer in my hand.

Sure take it to an rv shop where they have a hard time putting in screws and applying sealant.

In 38 years as a RV tech, I have fixed scores of RV units that Residential AC technicians attempted to fix. HOW do you check the Freon/410 charge on a RV unit?

1st if the temp split was low as well as suction line temp high indicating it could be a refrigerant side issue you install solder on gauge taps so you can use gauge manifold. Then you go by superheat subcool to determine refrigeration side issue. Pull charge and weigh to determine if a leak amd repair as needed.

A refrigeration system is a refrigeration system.

Now i do know many residential guys as well who cant even fix a home heatpump, but this is not rocket science for someone disciplined and proficient in Thermodynamics.

Even with a Google search to help you get the right answer, you are COMPLETELY WRONG. I love giving so called experts rope to hang themselves with. You do NOT have the expertise to work on and FIX RV A/C units. The ONLY way to verify a correct charge on a RV AC unit is by a temp corrected AMP draw at the compressor. NO OTHER WAY. A Temp differential will NOT be accurate enough to get the correct diag. May not be rocket science, but you seem to have a problem just using Bottle Rockets:S NEXT time you think you are so smart, think again. Doug

PS, a Refrigeration system is NOT a Refrigeration system.

This does not even deserve a reply.

I dont think I am smart...this is what I do for a living. Superheat/Subcooling and saturation temps are what determine a properly operating refrigeration system. Amp draw alone only tells a small piece of the equation. What you do is typical hack work of the rv industry. Amp draw alone is just a quick yes sir everything seems fine with your ac at this time while your here on your maint check. We are talking about an ac that is not working properly

And sorry to burst your bubble a refrigeration system is a refrigeration system, they all work on the same principles.

Funny. I show you do not understand RV AC systems and you dig in and still will not admit you do NOT know everything. Unlike systems you deal with. ALL RV AC systems are built EXACTLY the same for their Model and Size. EXACT same Freon/410 charged. NO variables and no reason to supercool to verify charge and operation. WHY do you hold QUALIFIED RV Technicians in such contempt? To charge a RV AC system, you solder in hi and lo Schrader valves, then evacuate and then use a DIAL-Charge to install the EXACT amount of Freon/410 in the AC. TOTALLY different from a Home/Industrial AC system. I have extensive RVP(Coleman)/Dometic factory training that qualifies me to work on RV AC systems. I am also NIASE certified to work on Automotive Dash AC systems. Doug
