I have recently installed a high efficiency furnace Lennox G61V and found that it is running longer than the old one. It is set for Single Stage operation and the blower runs continuously. The programmable thermostat(single stage) programs are the same. I find the air blowing to be mildly warm during heating. What could be wrong?? I thought I would be saving money on my gas bill!!!

The tech that put it in should have set it all up for you. Is the tstat set right for the right anticipation for that unit?

Don't panic, your new furnace is operating as it's supposed to. To achieve higher efficiencies, new gas furnaces must move more air over the heat exchanger than older furnaces so that as much heat as possible can be sent throughout the house.
The air that comes out of your furnace registers may not seem as warm as the air was from your old furnace, but it will heat your house just as well. In fact, better airflow can improve overall comfort by reducing air temperature differences from the ceiling to the floor throughout your entire home.
Here's a quote from the following website that explains it in a bit more detail
" Some mid- and high-efficiency furnaces offer additional features that provide greater comfort as well as additional energy savings. Furnaces with two-speeds can run on low speed up to 90% of the time, so they operate more quietly than single-speed furnaces.
On lowere speeds, the furnaces will run for a longer time, when it runs. Longer operating periods translate into fewer on/off cycles, fewer drafts and much smaller temperature swings -- only one or two degrees instead of the four-degree swings common with single-speed furnaces. Plus, better air circulation helps prevent your cold feet created by air "stratification" -- warm air rising to the ceiling and cold air settling on the floor. In short, you get consistent, even heat throughout your home.
Variable-capacity furnaces provide the ultimate combination of comfort, efficiency and quiet performance. In addition to the benefits of two-speed furnaces, they offer "smart" motors that can monitor your home's comfort needs and automatically adjust the volume and speed of air to provide the most efficient heating or cooling. They offer added electrical efficiency as well: the "smart" fan motors on today's variable-capacity furnaces use less electricity than a 100-watt light bulb. They operate so efficiently that they can actually increase the efficiency rating of your central air conditioning system and offer you added energy savings when you use continuous fan operation in any season."

I adjusted the blower speed for heating to Medium High, a notch up from the factory default of Medium Low. This seems to have helped and I noticed a slight decline in the furnace usage. I shall monitor any changes over the next few days and report back anything unsual.
Thanks to all who responded.Comment
