Selling heat pumps to over 60 countries worldwide, CTRE offers a wide range of products for consumers to choose from. As a heat pump manufacturer, we do not usually deal directly with end users to protect the interests of our local partners. Customers can enjoy a 2-5 year warranty with lifelong maintenance support. In addition, we provide installation and user guides, as well as controller software updates. Whenever you have a question, need product information, need technical support or want to purchase components, feel free to contact one of our local partners.

Maintenance Services

CTRE offers standard 24-month warranty. Customers can pay a small fee to extend the warranty to five years. Within the warranty period since the delivery date, if the product has any failure under normal usage, SPRSUN will provide free assembly parts. After the expiration of the warranty period, we will continue to provide lifelong maintenance services, with just a small amount of charges.
