Homeowners looking for a forced-air furnace can turn to Lowe's, Home Depot or Amazon to find the right heating unit for their needs. Lowe's and Home Depot offer in-store support for shoppers as well as online sales, and Amazon provides useful specifications for each unit sold online.
As of 2015, Lowe's offers forced-air furnaces from top brands, including Kelvinator and Winchester. The company provides online and in-store shopping, and both gas and electric options are available for purchase. The Home Depot also carries many major brands, including Century, Miller, Williams and King Electric. Shoppers who purchase a forced-air furnace from Home Depot online receive free shipping directly to their local store, potentially saving quite a bit of money due to the expense of shipping large and heavy items.
Amazon is one of the largest online retail marketplaces, and it gives shoppers the ability to pick and choose from a wide selection of manufacturers, models and retail vendors. Many orders fulfilled by Amazon offer free shipping directly to the purchaser's home, eliminating the need to move bulky furnace fixtures from a store location to where users plan to place the unit. Amazon Prime subscribers enjoy additional discounts on shipping for some items.
