For a gas furnace, it's all about efficiency in burning the fuel. The higher the efficiency rating, the more expensive the furnace is bound to be, but it will save you money in the long run by using less gas to achieve the same heating result. So, you will have to balance your pocketbook versus the efficiency of the furnace. If you're planning on staying in your home for a number of years, a high efficiency furnace may be the best investment for your pocketbook. Also, it will appeal to SOME buyers who understand what it means to have a high efficiency gas furnace, but I wouldn't say that most people will be overly worried about how efficient the furnace is as opposed to how old (or new) it is.
Hi Lillie! when we bought a new gas furnace the dealer wanted to know the footage of our house, the number of zones, if we wanted forced air or hot water. Talk to a reputable company and they will guide you through the process. I also found our local gas provider to be a good source. Newer furnaces are more energy efficient, and there are often rebate and buy back (of old equipment) programs available to lower your costs.
