Question 1

What if in the end my PCB can't be fixed? Have I wasted the 44 €?

Accepted Answer

Not entirely. The €35 covers the thorough inspection and gives you the truth without beating around the bush; the €9 is the reservation to return it to you. If the fault is unfeasible, we tell you clearly, and if you prefer not to have it sent back, we refund those €9. What we never do is charge you for a repair that isn't worthwhile.

Question 2

My boiler is showing a fault code. Are you sure it's the PCB?

Accepted Answer

Not always. Many codes are triggered by sensors, pressure switches, wiring, or the installation itself, not the electronics. That's why we diagnose first: if the fault is not in the PCB, we inform you before you spend on repairing it.

Question 3

How do I know if it's worth repairing it or buying a new one?

Accepted Answer

After the diagnosis, we provide you with two figures: the cost of repairing it and the cost of a new PCB (if available). This way, you can make an informed decision, not blindly. If repairing is not worthwhile, we will be the first to tell you.

Question 4

How do I pack the PCB so it doesn't arrive worse than it left?

Accepted Answer

Rigid box, anti-static bag (or paper, never bubbles stuck to the pins) and generous padding to prevent movement inside. Include your details, a phone number, and, if possible, the model of the equipment and the symptoms it has.

Question 5

How long will it take to give me the diagnosis?

Accepted Answer

As soon as we receive and register it, it enters the bank queue and we will notify you with the result and, if applicable, the estimate. We don't promise movie-like deadlines: we prefer to deliver rather than impress.

Question 6

Do you repair PCBs of any brand and age?

Accepted Answer

We work with boiler electronics, air conditioning, aerothermal systems, and inverters from almost any brand. However, we do reject the unfeasible: burnt-out, sulphated, heavily tampered PCBs, or those that are so old or cheap that they are not worth repairing.

Question 7

Can I show you a photo before paying?

Accepted Answer

Yes, and it's the smartest thing to do if you're unsure. Send us a photo of both sides of the PCB via WhatsApp, and we'll advise you without obligation on whether it's worth sending it.

Question 8

If you repair the PCB, do you guarantee that the boiler will work again?

Accepted Answer

We guarantee the work done on the PCB, but a unit can have more than one fault (sensors, motor, installation…). The specific warranty is indicated in the repair estimate or invoice.
