Our service technicians always take care of your CTA heat pump, regardless of whether or not you have subscribed to our CTAplus extended warranty or a service contract.
Carefree for years with CTAplus
With a CTA heat pump, you have chosen a high-quality, durable product. To ensure that your heat pump continues to run optimally for longer, regular maintenance and checks are important, even though heat pumps are generally considered to be low-maintenance. For newly installed heat pumps, we recommend that you take out a CTAplus extended warranty. This comprehensive cover offers you up to 12 years’ warranty from commissioning. Alternatively, or even after the CTAplus expires, we offer a flat-rate service contract for all heat pumps.
