Use the Trane System Customizer to get a better idea which system could be best to meet your home comfort needs.

• Take inventory of your system. Make a note of the model numbers on your current equipment. Search your files for the available paperwork. You should also be able to find the model numbers on the units themselves.
• Be prepared to talk with your Trane dealer about your geographic location, and the structure of your home—not to mention the specific comfort needs of you and your family. These are especially important if you're in the market for the first time, or putting a system in a home where there has never been a central system.
• Make sure the dealer performs a thorough structural analysis of your home. This will help determine the proper-sized system for your home. This analysis will include a load calculation to determine the proper type and size of your new Trane system.
• Think about financing. Remember, you're investing in your year-round comfort—not to mention the long-term comfort of you and your family.
• Prepare for installation day. Your Trane dealer will probably bring a couple of people with him to assist in the installation process.
• Have your dealer program the thermostat setting for you, go over the owner’s manual, and walk you through the (minimal) maintenance you will need to do yourself. Review the warranty information for your specific models.
