Subsequent Events [Abstract]
Subsequent Event	Note 15: Subsequent Event On April 30, 2015, a class action lawsuit was filed against our subsidiary, ClimateMaster, Inc. (“CM”), in the case styled Emmert, et al. v. ClimateMaster, Inc., in the United States District Court, Western District of Oklahoma. CM is a subsidiary within our Climate Control Business. The lawsuit alleges that a manufacturing defect in the air conditioning and heat pump equipment manufactured by CM has caused failures in certain valves used in such equipment resulting in damages sustained by consumers and the contractors, and further alleges that CM sold the equipment despite knowing of these defects. The plaintiffs are alleging that there are more than 100 class members and that the aggregate amount in controversy exceeds $5 million, exclusive of interest and costs. Plaintiffs seek actual and punitive damages, together with recovery of certain expenses. Because we have just been notified of this lawsuit, we have not had an opportunity to investigate the claims contained therein, but intend to vigorously defend this matter. We are also investigating whether such claims come within our insurance coverage, and, as of the date hereof, have not determined if the claims alleged in the lawsuit are covered under our insurance policy.
