My last furnace died down in last year’s winter and I wanted something better. I did a quick internet search and was impressed by the reviews on Ducane Gas Furnaces. I immediately purchased the furnace and had it installed. So far, I’m so impressed with this furnace. It heats quickly, runs well, and has saved me quite some amount of energy bill in comparison to my old one. If I were to make another purchase, I would still go for Ducane.

We purchased this unit back in 2014. It was a replacement to our previous gas furnace, which we had been using for more than twenty years. This unit is noticeably quiet and provides a cool and comfortable environment. With this unit, our energy costs are notably lower and so is the energy consumption. The variable quality allows it to run slowly with enough heat. This one is clearly among the best.

When my old furnace needed replacement in the fall of 2013, I was quite sure that I was going to buy the same brand yet again. I had lived in the house for more than twenty years and never had to repair the Ducane Gas Furnace. It heats our home in a short time and has significantly lowered our gas and energy bills. I’ve had no issues with it but I’ve had it checked and serviced every year to ensure that it continues to deliver optimally.

Rated this 4 stars only because I wish it was quieter than it is when operating. It replaced a 14 year old condenser with a failed compressor. The new unit is only marginally quieter than the old unit.

This unit is horrible! I had two of the Ducane units installed at both side
This unit is horrible! I had two of the Ducane units installed at both sides of my home less than four years ago. Both models freeze regularly and bring water in my home. I live in Arizona where we experience a lot of dust and so their filters require replacement in every three to four weeks. They are also noisy and I haven’t noticed any difference in the temperature of my home. It is a total waste of money. This unit is horrible!

I am so angry at my husband for purchasing this model. The power vent motor in this furnace died in less than a year of use and three months later I was required to change the ignitor and gas valve. It seems like everything is wrong with this Ducane. It vibrates and sounds like a train when on. When I called the technician about the issues, they said that it was normal and I had no cause for alarm. This Ducane unit is so bad I don’t even know what more to say.
