Have you signed a CTAplus extended warranty contract? Then you can sit back and relax. Call-outs of heat pump service technicians are included in this warranty extension.

The warranty period granted by CTA to the CTA contracting partner, typically the heating installer, and the subsequent installation warranty from the installer will cover any so-called 'latent defects' arising during the first 5 years after commissioning. In other words, defects that were present from the very beginning. The tested and approved Swiss quality of our Swiss-made heat pumps means that any such defects are a rarity. Technical defects that occur following installation and commissioning are not covered by the installer’s installation warranty. The post-warranty period call-out charges apply to remedying such defects if any should arise. We recommend that you take out a CTAplus extended warranty. This contract covers all defects to heat pumps, including those that occur after commissioning.
