Carrier's website enables you to search for dealers by ZIP code. When reporting faulty parts or equipment, provide the dealer with the model and serial number of the equipment in question.
The Carrier site offers extensive guides to maintenance and troubleshooting of its equipment. The site provides tips on air conditioner, furnace and boiler maintenance. It also supplies a list of simple preventative measures to keep equipment running efficiently and reliably.
The troubleshooting guide lists a range of commonly encountered problems, such as systems not running, units overheating or not cooling correctly. Consult this guide before seeking assistance from a service engineer. Carrier customers with an Infinity system with remote access can set up their access to allow the approved Carrier expert to diagnose potential problems over the telephone. Customers without this facility must contact their Carrier dealers.
The Carrier site also has a document store. Enter the four-to-six digit serial number or search for the product by type and model. The database contains information on warranties, installation, product data and brochures. There are also owner manuals that can help with troubleshooting. All documents are in PDF format.
Finally, Carrier provides an option to extend the limited warranty of most products by up to an additional five years by registering them within 90 days of purchase.
