Information on where to purchase an oil furnace can be found on the manufacturer's website in most cases, such as with brands like Rheem, Trane and Carrier. Additionally, some sites offer an automated function for locating a dealer in a geographical area.
A review of the top six oil furnaces for 2015 includes models from Trane, Rheem, and Carrier, as rated by WebHVAC. These brands are also included in a list of leading manufacturers from Furnace Price Guidelines, as well as rated by consumers among the top brands by Furnace Compare. In the latter's review, Trane earned the ninth spot, Rheem earned the 15th spot, and Carrier followed at the 25th. Trane earned a top five rating from consumers for the XC95m model, with a score of 4.5 out of a potential 5 stars, in another review from Furnace Compare.
Trane's website offers an automated function to find a local dealer in the southern area of the United States, while Rheem offers a similar function for dealers nationwide. Carrier offers purchasing options and advice on its official website.
It's strongly recommended to have a licensed contractor assess the structure prior to purchasing an HVAC unit of any kind, especially online, according to Rheem. A quality contractor aligns himself with the best brands, according to Furnace Price Guidelines.
