Since 1928, Armstrong Air has been a smart choice for homeowners, and a constant recommendation from dealers.

We can sell any brand and we have sold many brands including American Standard. Seeing higher and higher warranty claims on American Standard and other brands, we feel the Armstrong/Lennox brand is the best-priced and most reliable equipment with excellent support from the local distributer.
