How much does it cost to install a new AC and furnace?

There isn’t a single set price. Your AC and furnace installation cost depends on your home, ductwork, and the efficiency level you choose. We provide free proposals. Current promotions include $1000 off a new Lennox comfort system. Financing is available with options as low as $120/month for many AC or heat pump installs, and ductless mini-splits as low as $65/month (on approved financing). Installations include warranty protection on replacements. We serve Tucson, Marana, Oro Valley, and nearby areas.
