We read everything. The messages we can act on fastest:

Corrections — a wrong number, an outdated rule, a broken official link. These get priority; see our methodology for how corrections are handled.
Questions about the content — if a guide left your question unanswered, telling us is the most useful feedback we can get.
Installers and partners — if you are an HVAC company interested in working with Klimata Lab, introduce yourself briefly (city, services, F-gas certification).

Please note: Klimata Lab is an independent information resource. We are not an installer and we do not sell equipment, so we cannot quote or carry out installation work ourselves.
