IIS 90 Two-Stage Furnace
The Arcoaire IIS 90 series is built for years of dependable operation, with a durable steel cabinet and advanced ignition system. Compared to single-stage furnaces, which heat up and shut down quickly, leaving your home either too hot or too cold, the IIS 90 provides remarkably even heat. The furnace comes with a lifetime warranty on the primary and secondary heat exchangers, a 5 year parts warranty plus a 7 year No Hassle warranty.Find A Contractor Find Rebates For This Product
