Job photos and customer addresses.
Not something to type into a shared chatbot.
Private LLM hosting on a dedicated machine in EU-Central, for HVAC contractors drafting quotes from job photos, cleaning up dispatch notes, or summarizing service history on a machine assigned to your company alone.
Not legal or compliance advice. This page describes GPUwerk's infrastructure and contractual commitments. It is not an opinion on your obligations as an HVAC contractor, and it is not a claim of any specific certification on GPUwerk's behalf. Check with your own advisor before deciding what can run where. See also private LLM hosting for construction for the adjacent trades setting, and private LLM hosting for franchise businesses if you operate under a franchise agreement.
Where an LLM fits into an HVAC contractor's office
This is about the estimating, dispatch, and record-keeping side of running a crew, not diagnosing a unit in the field.
Quote drafting from photos and descriptions
A technician snaps a photo of a rusted-out condenser or a furnace nameplate and types a two-line description; a model turns that into a line-item quote in the format your office already uses. The photo and the address it was taken at are tied to a specific customer, exactly the kind of record most contractors would rather not send to a shared vendor's servers.
Dispatch scheduling notes
Cleaning up a dispatcher's shorthand into a clear job ticket, with the unit type, symptom, and access instructions in a consistent format before it goes to a technician's phone. See the private AI shift scheduling guide →
Service-history summarization
Pulling a customer's past visits, parts replaced, and warranty status into a short brief before a technician arrives on site, so nobody is re-reading five years of paper tickets in the driveway.
On certifications and compliance frameworks
GPUwerk has not published ISO 27001, SOC 2, or any other formal certification, and this page makes no claim that hosting on GPUwerk satisfies any specific data protection regulation on its own. What GPUwerk provides is a dedicated single-tenant machine, a published GDPR Article 28 DPA with no sub-processors for instance workloads, and a documented answer to who can reach the machine and what happens to data on termination. If your compliance program requires a specific framework, that gives your own advisor a concrete starting point to assess against your requirements, not a substitute for the assessment itself.
What's actually in the contract
For your office manager or IT contact to review directly.
| Question | Answer |
|---|---|
| Where does it run? | EU-Central, on a dedicated single-tenant machine assigned to your company |
| Who operates it? | PRINT IT! SE, a Societas Europaea registered in Prague, Czech Republic. No US parent entity. |
| Who can reach the instance? | Through the instance itself, only holders of your SSH keys; password login is disabled fleet-wide. GPUwerk keeps infrastructure administrator access to the underlying machine, as on any hosted service, and under the DPA does not use it on your content except at your request for support or where a legal obligation requires it. |
| Does GPUwerk see customer data? | No. We host the hardware and, under the DPA, do not access, read, copy, index or analyse workload content. |
| Sub-processors for the workload? | None, listed at /legal/sub-processors |
| DPA (GDPR Art. 28)? | Published at /legal/dpa, no charge |
| Certifications? | None published (no ISO 27001 or SOC 2 claimed). Assess against your own compliance requirements. |
| Data on termination? | Container and workspace volume deleted from the node, then the node is sanitised before reassignment. Filesystem deletion, not a cryptographic erase; export what you need before terminating, since it isn't reversible. |
| Pricing | Spark-1x from $0.79/hour on demand, billed per minute; Spark-2x from $1.79/hour. A customer-requested stop holds the reservation at 75% of the running rate. See /pricing for full detail. |
Questions we get from HVAC contractors
Is it safe to put customer job photos and addresses into an LLM?
That depends on where the model runs and who can reach it, not the model itself. On a GPUwerk dedicated instance in EU-Central, the machine is assigned to your company alone and reachable only through your SSH keys; GPUwerk does not access, read, copy, index or analyse what runs on it except at your request for support or where a legal obligation requires it. Whether a specific use of customer data meets your own regulatory obligations is for your own advisor to confirm.
Is GPUwerk certified for handling customer service records?
GPUwerk has not published ISO 27001, SOC 2, or similar certifications. If your compliance program requires a certified provider or a specific control framework, a dedicated single-tenant instance with a published DPA and no sub-processors gives you a documented starting point to assess against your own requirements, not a substitute for that assessment.
Do you sign a DPA covering customer and job data?
Yes, a standard GDPR Article 28 DPA is published at /legal/dpa at no charge, and there are no sub-processors for instance workloads.
Does GPUwerk train on our job records?
No. GPUwerk runs infrastructure, not models. There is nothing for GPUwerk to train on, since we do not access instance content except as described in the DPA.
