Can carpet cleaning void your carpet warranty?

Can the wrong cleaning void a carpet warranty?

It can, according to the carpet industry. The Carpet and Rug Institute, the carpet manufacturers' trade association, says every manufacturer requires proper maintenance and that failing to follow the maker's maintenance guidelines may void your warranty. The Federal Trade Commission adds a limit from federal law: a manufacturer generally cannot require you to use specific parts or services to keep coverage unless it provides them free or has an FTC waiver. What your own carpet's warranty requires is written in it, and that document, not this guide, settles the question for your carpet.

What does the carpet industry say warranties require?

The institute's statements, which are the industry's own, are these:

• Carpet should be cleaned the way the manufacturer specifies, approximately every 12 to 18 months.
• Homeowners should check their carpet warranty for its specific requirements, and many carpet manufacturers recommend Seal of Approval products in their residential warranties.
• Seal of Approval cleaners are recommended and "sometimes required" by the manufacturer to ensure warranty protection.
• Using products other than those the institute has certified could void your warranty.

The Seal of Approval is the institute's own program. It tests cleaning solutions, machines and systems in a laboratory, and the institute says cleaning professionals gain its certification when they use approved products.

What does federal law say a warranty can demand?

The FTC's warranty guidance gives homeowners four useful points.

• You can read it first. Whenever there is a warranty, the FTC says, the law requires that it be available for you to read before you buy.
• Coverage can depend on maintenance. The FTC suggests asking whether a warranty covers only problems that happen after you maintain or use the product according to the directions. For carpet, that is the cleaning section.
• Tie-ins are limited. It says federal law says a manufacturer cannot require you to use specific parts or services to keep warranty coverage unless it gives them to you free or gets an FTC waiver.
• Implied warranties exist too. It says state laws create implied warranties that cover almost everything you buy, including a warranty of fitness for a particular purpose when you buy on a seller's advice that a product suits a particular job, and that these can cover problems a written warranty does not.

In practice: follow the maintenance terms your warranty actually states, and if it names a product or service, ask the manufacturer how that fits the FTC's rule.

Which records should you keep?

• The warranty itself. The FTC says to save a copy, and to keep the receipt with it, since the receipt proves the date of purchase and that you are the original owner.
• Every cleaning receipt. If coverage depends on maintenance, your receipts are the evidence. Ask each company to list the date, the method and the products on the invoice.
• The carpet's maker and style. The institute's standard says a certified cleaner should ask who made your carpet and what type it is, so have that ready.
• Written promises. The FTC says to get any spoken promise in writing, because a business may later refuse a service that was promised only out loud.

What about the cleaning company's own promises?

They are separate from the carpet maker's warranty. Read them for what they actually promise. When New York's Attorney General settled with a carpet cleaning company in 2000, the company agreed to tell customers that results may vary, that heavily stained carpet may need special cleaning, and to stop implying that its basic steam cleaning cleaned all carpets.

Pennsylvania's consumer protection law lists, among unfair or deceptive practices, representing that services are of a particular standard or quality when they are not, and claiming a certification, approval or affiliation a business does not have. A company that says its work "meets your warranty" should be able to tell you which terms it means.

What if a warranty claim is refused?

The FTC's steps are to contact the seller first and, if the seller does not resolve it, to write to the manufacturer at the address in the warranty, by certified mail with a return receipt. It says a company may have the right to fix the product before refunding, and that a defect reported during the warranty period must be corrected even if the warranty expires before the repair is done. If that fails, it says to report the company to the FTC and your state attorney general.

In Pennsylvania the Attorney General takes consumer complaints online. Bucks County's consumer protection office lists warranties that are not honored among the problems it mediates, and Delaware County's consumer affairs office offers voluntary mediation of consumer complaints.
