CO2 tank exchange in San Juan: Hydro Warehouse PR swaps a 20 lb tank for $50.18
A call4me customer's assistant called Hydro Warehouse PR in Spanish about a 20 lb CO2 tank, then called two local drivers to run the swap. Here is what staff said, what the drivers quoted, and all five recordings.
Nick Khami / / number verified / 9 min readThe short answer: Hydro Warehouse PR does a 20 lb CO2 tank exchange at 44-46 Calle Progreso, inside Corona Comercial Park in Santurce, San Juan, PR 00907. Its official website lists (787) 506-8385 and (787) 688-8384, and hours of Monday to Friday, 9:00 AM to 5:00 PM, closed Saturday and Sunday. The assistant dialed (787) 506-8385, the first number on that site, and a person answered with the store's name in the first second. There is no phone menu.
What staff told a call4me customer's assistant on Friday, October 16, 2026:
- It's an exchange, not a refill. You bring your empty tank and leave with a full one. They don't refill your own cylinder.
- On the spot, while you wait. "No, es de inmediato. Yo tengo los tanques llenos." (No, it's immediate. I have the full tanks.)
- $50.18 total. "Cuarenta y cinco dólares más tax, cincuenta con dieciocho." That's $45 plus tax. When the assistant asked about a deposit or extra charges, staff said "correcto" to $50.18 with none.
- 20 lb only. "Solamente trabajo el tamaño de veinte libras." A full tank to buy outright is $350 plus tax.
- Your tank's hydro test must be within 3 years. Staff said the empty has to be "certificado, al día", and confirmed that means a hydrostatic test date within three years.
- Food grade CO2 with a CGA 320 valve. Staff said "sí" when the assistant asked about both.
- The full tank comes sealed with a plastic seal from the gas company, not a cap.
- Someone else can bring the tank. A driver can drop the empty and take the full one, paying in person and showing ID.
- Pay in person. Staff preferred that over paying by phone, and said they don't offer or recommend a delivery or courier service.
- Finding it: staff described the store as inside the Corona industrial complex, with a "Cervecería Corona" sign outside and a gated entrance. "Si viene y se acerca y le preguntan, le dejan pasar." (If you come up to it and they ask you, they let you through.)
Staff also said they speak English, so you don't have to call in Spanish.
The assistant then called two local delivery services to take the tank across town. One quoted $120 and was booked for a pickup about an hour later. The other quoted $200 by PayPal and was not booked. The rest of this page has the details and all five recordings.
What the calls established
All five calls were placed on October 16, 2026, between about 9:04 and 10:00 AM Puerto Rico time. They are in Spanish. Each recording below has the original Spanish transcript and a labeled English translation.
| Question | Answer on the call |
|---|---|
| Refill or exchange? | Exchange only. You bring the empty and take a full tank |
| Wait time | Immediate, while you wait; staff keeps full tanks in the store |
| Price | $50.18 total ($45 plus tax); staff said "correcto" to no deposit or extra charges |
| Tank sizes | 20 lb only |
| Buying a full tank | $350 plus tax |
| Requirement for your empty | Hydrostatic test date within 3 years |
| Gas grade and valve | Food grade CO2, CGA 320 valve ("sí" to both) |
| Full tank seal | A plastic seal from the gas company, not a cap |
| Who can bring the tank | A driver can come instead, paying in person with ID |
| Payment | In person preferred; no phone payment arranged |
| Delivery | Not offered; no courier recommended |
| Hours on the call | 9:00 AM to 5:00 PM, "preferiblemente antes de las cinco" (preferably before five) |
| Gross weight of a full 20 lb tank | Unknown. "No sé, porque no lo he pesado" (I don't know, I haven't weighed it) |
| Language | Staff said they also speak English |
And the two drivers called for the same errand, picking up the empty in Old San Juan, swapping it at Hydro Warehouse PR and bringing back the full tank:
| Local delivery service | Car and concierge service | |
|---|---|---|
| Quote | $120, plus the $50.18 exchange paid at the store | $200 |
| Earliest pickup | About one hour | About one hour |
| Payment | Cash or a mobile payment (it sounded like ATH Móvil); a follow-up call settled on cash on return | PayPal |
| Tank handling | Accepted upright and secured in the cargo area | Not discussed before the recording ends |
| Result | Booked; a second call confirmed about 11:00 AM and $170.18 total | Not booked; the recording ends on an unanswered question |
We don't name either driver service. We couldn't find an official website for either one to check the number against, and the delivery service's number is the driver's own direct line.
How the exchange works
Ask about a co2 tank exchange rather than a refill. When the assistant asked whether they could refill the customer's own tank, staff corrected it: "No es un relleno, es un intercambio." (It's not a refill, it's an exchange.) If you need your own cylinder filled and returned, this store is the wrong stop. If you just need a full 20 lb tank, it's quick.
Check the hydro test stamp before you go. Staff's first condition, repeated in both calls, was that the tank be "certificado, al día", and the follow-up call pinned that down to a test date within three years. The calls didn't cover what happens to a tank that fails, beyond the assistant's own plan to bring it back unpaid.
Bring cash or a card and an ID if you're sending someone. Payment is in person, and staff said a driver can do the swap as long as they pay there and show identification. Staff didn't ask for a reference name in the answer, though at the end of the second call they asked for the customer's name and the assistant gave it.
Where to exchange a CO2 tank if you can't drive it there
Staff said Hydro Warehouse PR doesn't deliver and doesn't recommend a courier, so the assistant found drivers itself.
The local delivery service said yes right away, quoted $120 for the errand, and said a driver could pick up in about an hour. The assistant described the cylinder as compressed, non-flammable, and needing to ride upright and secured in the trunk or cargo area, not a closed passenger cabin, and the driver accepted. A second call six minutes later confirmed a pickup around 11:00 AM Puerto Rico time and $170.18 total ($120 for the run plus $50.18 for the exchange), paid in cash when the driver returns with the full tank.
The car and concierge service quoted $200, payment by PayPal, earliest pickup in an hour. The recording ends while the assistant is asking for the driver's name and phone and the cancellation policy, so nothing was booked.
What the calls did not confirm
- That the exchange happened. The recordings stop at a booked pickup. They don't show the driver arriving, the tank passing the 3 year check, or a full tank coming back.
- The weight of a full tank. Staff didn't know. The assistant told the first driver a full tank weighs "about 50 to 55 pounds". That was the assistant's own estimate, not something Hydro Warehouse PR said.
- Food grade and CGA 320 in the first call. In the first call the assistant described the customer's tank that way, and staff didn't respond to it. Staff said "sí" to both in the follow-up call.
- Weekend hours. The calls covered only that Friday, 9:00 AM to 5:00 PM. The website says closed Saturday and Sunday.
- Other tank sizes. 20 lb only. The calls don't say where to exchange a 5 lb or 10 lb tank in San Juan.
- The driver's ID and the tank rule. In the follow-up, the assistant asked whether the driver had his own ID and how he would carry the tank in the same question. He answered only about the cargo area.
- The concierge service's terms. Driver, payment details and cancellation policy were all unanswered.
A few things our side got wrong
The calls show the assistant making some mistakes, and we left them in:
- It read out the customer's own phone number as the place to send the payment text. The driver corrected it: "No, eso no es el número de pago" (No, that's not the payment number). That number is muted.
- It assumed answers. It asked "¿Es en 44 Calle Progreso, en Corona?" instead of asking for the address. In the follow-up it summed up "sin depósito ni cargos extra" (no deposit or extra charges) itself, and staff agreed.
- It answered "is this a computer?" honestly. Staff asked "¿Esto es una computadora que me está hablando, o esto es una persona?" and the assistant said it was the customer's digital assistant. The call went on normally after that.
Listen to the calls
Every recording keeps its original voices and full timing. The customer's name, the assistant's name, the store employee's first name, the driver's name and direct number, the customer's phone number and the pickup address are muted. Hydro Warehouse PR's name and address stay audible. No dead air was shortened. The transcripts were checked against the saved call text and two independent automatic transcriptions of each source and each export; no human listening verification is claimed.

Representative: Hydro Warehouse, buenos días.
AI agent: ¡Buenos días! Esta llamada puede ser grabada. Soy [assistant name muted], asistente de [customer name muted]. Llamo por una recarga de CO2. ¿Con quién hablo?
Representative: Con [staff name muted].
AI agent: Hola, [staff name muted], ¡mucho gusto! ¿Me confirma, por favor, si este es Hydro Warehouse PR?
Representative: Sí.
AI agent: Perfecto. Mira, [customer first name muted] tiene un tanque de 20 libras de CO2 grado alimenticio con válvula CGA 320. ¿Ustedes lo pueden rellenar?
Representative: ¿Esto es una computadora que me está hablando, o esto es una persona?
AI agent: Soy la asistente digital de [customer name muted], trabajando directamente para él. Solo estoy coordinando la recarga. ¿Me puede decir, por favor, si pueden rellenar su propio tanque?
Representative: De 20 libras, sí. Pero no es un relleno, es un intercambio. Él me trae el tanque que esté certificado al día, y [unclear] después yo entrego entonces un tanque lleno.
AI agent: Perfecto, entiendo. Entonces es intercambio, no recarga en el mismo sitio. ¿Cuánto sale hoy el total, con impuestos, por un intercambio de un tanque de 20 libras?
Representative: Le dejo saber en breve. [Unclear, possibly "No se me retire."]
AI agent: Dale, gracias. Aquí espero.
Representative: 50 con 18.
AI agent: Perfecto, gracias. 50 con 18, o sea, 50 dólares con 18 centavos. Gracias. ¿Se puede pagar a distancia?
Representative: Sí, 50... [overlapping]
AI agent: Sí, 50 con 18.
Representative: A distancia, usted dice, por teléfono. En este caso, preferiría que fuese presencial.
AI agent: Entiendo. En ese caso, ¿tienen algún mensajero o transportista que recomienden que sí transporte tanques de CO2?
Representative: No, no, no ofrecemos ese servicio.
AI agent: Está bien. Para recoger el tanque lleno, ¿cuál es la dirección exacta de ustedes, por favor? ¿Es en 44 Calle Progreso, en Corona?
Representative: Sí, es dentro del complejo industrial Corona. Dentro del complejo, afuera dice Cervecería Corona. Tiene control de acceso, tiene una valla mecánica. Pero si viene y se acerca y le preguntan, le dejan pasar.
AI agent: Perfecto, gracias. Entonces dentro del complejo industrial Corona, donde afuera dice Cervecería Corona. ¿Y hasta qué hora están abiertos hoy?
Representative: Hasta las 5 de la tarde.
AI agent: Listo, gracias. Y para que [customer first name muted] no tenga problema, ¿su tanque vacío tiene que venir con tapa o algún requisito especial?
Representative: No, no, no, no. El tanque normalmente me lo traen vacío, y ya. Sí. Nosotros lo entregamos lleno y sellado. Pero el sellado no es con una tapa, es con un plástico que la compañía le pone.
AI agent: Perfecto, entendido. Entonces [customer first name muted] lo lleva vacío y ustedes entregan uno lleno y sellado. Con eso estoy, [staff name muted]. Muchas gracias por todo. ¡Que tengas buen día!
Representative: Okay, buen día.

Representative: Hydro Warehouse, good morning.
AI agent: Good morning! This call may be recorded. I'm [assistant name muted], [customer name muted]'s assistant. I'm calling about a CO2 refill. Who am I speaking with?
Representative: With [staff name muted].
AI agent: Hi, [staff name muted], nice to meet you! Can you confirm this is Hydro Warehouse PR?
Representative: Yes.
AI agent: Great. So, [customer first name muted] has a 20 lb tank of food grade CO2 with a CGA 320 valve. Can you refill it?
Representative: Is this a computer talking to me, or is this a person?
AI agent: I'm [customer name muted]'s digital assistant, working directly for him. I'm just coordinating the refill. Could you tell me whether you can refill his own tank?
Representative: A 20 lb one, yes. But it's not a refill, it's an exchange. He brings me the tank, with its certification up to date, and [unclear] then I hand over a full tank.
AI agent: Great, I understand. So it's an exchange, not a refill on site. What's the total today, with tax, for exchanging a 20 lb tank?
Representative: I'll let you know shortly. [Unclear, possibly "Don't hang up."]
AI agent: Sure, thanks. I'll wait.
Representative: 50.18.
AI agent: Great, thanks. 50.18, so 50 dollars and 18 cents. Thanks. Can it be paid remotely?
Representative: Yes, 50... [overlapping]
AI agent: Yes, 50.18.
Representative: Remotely, you mean by phone. In this case, I'd prefer it be in person.
AI agent: I understand. In that case, is there a messenger or transport service you'd recommend that does carry CO2 tanks?
Representative: No, no, we don't offer that service.
AI agent: That's fine. To pick up the full tank, what's your exact address, please? Is it 44 Calle Progreso, in Corona?
Representative: Yes, it's inside the Corona industrial complex. Inside the complex, the outside says Cervecería Corona. It has access control, it has a mechanical gate. But if you come up and they ask you, they let you through.
AI agent: Great, thanks. So inside the Corona industrial complex, where the outside says Cervecería Corona. And until what time are you open today?
Representative: Until 5 in the afternoon.
AI agent: Got it, thanks. And so [customer first name muted] doesn't have any trouble, does his empty tank need a cap or anything special?
Representative: No, no, no, no. People normally just bring me the tank empty, and that's it. Yes. We hand it over full and sealed. But the seal isn't a cap, it's a plastic one the company puts on.
AI agent: Great, understood. So [customer first name muted] brings it empty and you hand over a full, sealed one. That's all I need, [staff name muted]. Thank you so much. Have a good day!
Representative: Okay, good day.
Call 2: Hydro Warehouse PR follow-up, timing, test date and who can bring the tank
3 minutes 10 seconds. The assistant called back four minutes later.

Representative: [Unclear greeting; the saved call text has "Hidrohouse, buen día"]
AI agent: Buenos días, [staff name and assistant name muted], asistente de [customer name muted], la que llamó hace unos minutos por el intercambio de CO2. Esta llamada puede ser grabada. Tengo dos preguntas rápidas. La primera es, ¿el intercambio es inmediato hoy mismo mientras espera, o tiene que dejar el tanque vacío y recoger el lleno otro día?
Representative: No, es de inmediato. Yo tengo los tanques llenos. Yo siempre me encargo de asegurarme de tener tanques de CO2 llenos en la tienda para eso mismo. Después que el tanque esté certificado, esté al día, no hay problema. Tú me lo entregas y yo te doy el otro. 45 dólares más tax, 50 con 18. Pero solamente trabajo el tamaño de 20 libras.
AI agent: Ah, buenísimo.
Representative: Solamente trabajo el tamaño de 20 libras, y si quisiera comprar un tanque adicional, vendo tanques también, llenos. Eso tiene un costo de 350 dólares más impuestos.
AI agent: Ajá, entendido. Entonces, el intercambio es al momento y son 50 con 18 en total, ¿cierto?
Representative: Sí.
AI agent: Genial, gracias. Y cuando dices "certificado al día", ¿te refieres a que la fecha de la prueba hidrostática esté dentro de cierto número de años? ¿Cuántos?
Representative: Sí, tres años.
AI agent: Perfecto, gracias. Otra cosa, los cilindros que entregan llenos son de CO2 grado alimenticio con válvula CGA 320, ¿cierto?
Representative: Sí.
AI agent: ¿Y cuánto pesa en total un cilindro lleno de 20 libras? O sea, el peso bruto.
Representative: Ay, no sé, porque no lo he pesado.
AI agent: No hay problema. Otra pregunta, si no va [customer first name muted] en persona, ¿puede ir un chofer a dejar el vacío y recoger el lleno? ¿Necesitan algún nombre de referencia o algún dato?
Representative: No, después de que me paguen presencialmente, con identificación.
AI agent: Genial. Entonces, para confirmar, son 50 con 18 en total, sin depósito ni cargos extra, y el intercambio inmediato, ¿correcto?
Representative: Correcto.
AI agent: Perfecto. Y por último, ¿hasta qué hora hoy reciben intercambios?
Representative: De 9 de la mañana a 5 de la tarde.
AI agent: ¡Genial, muchas gracias!
Representative: Preferiblemente antes de las 5.
AI agent: Perfecto, entendido. Entonces, intercambio al momento por 50 con 18, tanque de 20 libras, certificado dentro de tres años, solo ese tamaño, y mejor ir antes de las 5. Listo, [customer first name and overlapping words muted]
Representative: [Overlapping words muted] ¿me puedes repetir el nombre del cliente, por favor?
AI agent: Claro que sí. [Customer name muted].
Representative: Okay. Le puedes decir a [customer first name muted] que cualquier cosa, nosotros también hablamos inglés acá, que no hay ningún problema.
AI agent: Ay, muchísimas gracias. Eso es todo por ahora. ¡Gracias, chao!
Representative: Gracias. Bye-bye.

Representative: [Unclear greeting; the saved call text has "Hidrohouse, good day"]
AI agent: Good morning, [staff name and assistant name muted], [customer name muted]'s assistant, the one who called a few minutes ago about the CO2 exchange. This call may be recorded. I have two quick questions. First, is the exchange immediate, today, while you wait, or do you have to leave the empty tank and pick up the full one another day?
Representative: No, it's immediate. I have the full tanks. I always make sure to keep full CO2 tanks in the store for exactly that. As long as the tank is certified, up to date, no problem. You hand it to me and I give you the other one. 45 dollars plus tax, 50.18. But I only work with the 20 lb size.
AI agent: Oh, great.
Representative: I only work with the 20 lb size, and if you wanted to buy an extra tank, I sell full tanks too. That costs 350 dollars plus tax.
AI agent: Uh huh, understood. So the exchange is on the spot and it's 50.18 total, right?
Representative: Yes.
AI agent: Great, thanks. And when you say "certified, up to date", do you mean the hydrostatic test date has to be within a certain number of years? How many?
Representative: Yes, three years.
AI agent: Great, thanks. One more thing, the full cylinders you hand over are food grade CO2 with a CGA 320 valve, right?
Representative: Yes.
AI agent: And how much does a full 20 lb cylinder weigh in total? The gross weight, I mean.
Representative: Oh, I don't know, because I haven't weighed it.
AI agent: No problem. Another question: if [customer first name muted] doesn't go in person, can a driver drop off the empty and pick up the full one? Do you need a reference name or any details?
Representative: No, as long as they pay me in person, with ID.
AI agent: Great. So, to confirm, it's 50.18 total, no deposit or extra charges, and the exchange is immediate, correct?
Representative: Correct.
AI agent: Great. And last, until what time today do you take exchanges?
Representative: From 9 in the morning to 5 in the afternoon.
AI agent: Great, thank you so much!
Representative: Preferably before 5.
AI agent: Great, understood. So, exchange on the spot for 50.18, 20 lb tank, certified within three years, only that size, and better to go before 5. Okay, [customer first name and overlapping words muted]
Representative: [Overlapping words muted] can you repeat the customer's name for me, please?
AI agent: Of course. [Customer name muted].
Representative: Okay. You can tell [customer first name muted] that if anything comes up, we also speak English here, no problem at all.
AI agent: Oh, thank you so much. That's all for now. Thanks, bye!
Representative: Thanks. Bye-bye.

AI agent: Genial. Antes de seguir, ¿quién es al teléfono? Solo para confirmar: es un cilindro de CO2 comprimido, no inflamable, pesa unas 50 a 55 libras lleno, y tiene que ir vertical y asegurado en la cajuela o área de carga, no en una cabina cerrada de pasajeros. ¿Eso lo aceptan?

AI agent: Great. Before we go on, who's on the phone? Just to confirm: it's a compressed CO2 cylinder, non-flammable, it weighs about 50 to 55 pounds full, and it has to ride upright and secured in the trunk or cargo area, not in a closed passenger cabin. Is that okay?

AI agent: Thanks, [phone number muted]. Great, and the pickup is in Old San Juan. The destination is Hydro Warehouse PR in the Corona Industrial Complex, and they do the swap on the spot, it costs 50.18, paid there in person, reimbursed separately.

AI agent: Great, then we're set for today. Thank you so much, [driver first name muted].

How to exchange a CO2 tank by phone first
If you're looking up co2 tank exchange near me in San Juan, a two minute call saves a wasted trip. These are the questions that settled it here:
- Refill or exchange? Some shops fill your own cylinder; this one only swaps.
- Which sizes? Hydro Warehouse PR said 20 lb only.
- What's the test date rule? Here, a hydrostatic test within three years.
- Total with tax, and any deposit? $50.18, and staff said "correcto" to no deposit or extra charges.
- On the spot, or drop off and come back? Here, on the spot.
- Can someone else bring it? Here, yes, paying in person with ID.
- Until what time? Here, 9:00 AM to 5:00 PM, ideally before 5.
If you need the tank moved, ask the driver to confirm upright transport in the cargo area, the total including the exchange, and how payment works, and keep your own phone number out of it unless you want them calling you.
Ask your assistant to make the call
Connect call4me to your assistant with the Claude Code guide or the Codex guide. This is a suggested brief, not what the customer used:
Call Hydro Warehouse PR in San Juan at (787) 506-8385. You can speak Spanish or English. Ask whether they can exchange my empty 20 lb CO2 tank today while I wait, the total with tax, whether there's a deposit, and what the hydro test date has to be. My tank's test date is [month and year]. Ask whether [driver or friend] can bring it instead of me and what they need to show. Don't book, pay or give my phone number. Tell me exactly what they said, and separate what staff said from anything you assumed.
