What happens if this breaks down?

HVACDirect.com gives you lifetime tech support. Many common problems can be solved with a phone call to us. HVACDirect.com is an authorized dealer of ACiQ, therefore equipment we sell carries the full manufacturer's warranty. The warranty applies to all parts. You have to register the products online in order to extend the warranty to the full 10 years, otherwise the term is 5 years. If a part fails under warranty, you will not pay anything for the replacement part. Should a part fail under warranty, the first step is to have a professional confirm what part needs to be replaced. Then, contact us at customerservice@hvacdirect.com or by calling and asking for customer service.
