So that is what I think. It has been mild here, so we set the t stat to 50, if it is set any higher, the temp really goes up. Today I did what you suggested, and yes, if the 60 amp is on, then the furnace is on and turning the meter nicely. If only the 30 amp is on, then nothing, no fan, no meter spinning. The meter spins almost as fast or equal to the water heater if it is the only thing on. What baffles me is why the furnace stays on, 24 hours when we set it to auto or on or recirc, it seems to just keep running. It seems to me if it was just the fan and no heat strips, the meter would barely spin, am I right? any way it looks like something is sqewed, so I will have the company who installed it check it out, I dont know if it is still under waranty or not. The fact that it is a two story and the heat vents are all in the ceililngs does not help. and today it was still 67 downstairs and 10 degrees higher upstairs, when i put a digital thermometer at the upstairs vent, it reads about 85 coming out. and there is only one return at the top of the stair well, nothing in the down stairs ceiling. Thanks for all your help in sleuthing this thing, I really need a good tech to come over and check the t stat and the furnace and make sure all the systems are normal. Thanks again. I really like how you all pitch in and give different sides to the problem.( I was once a home inspector, but could not afford the E&O insurance our state wants.)

Thanks Dave, I will try that today, we have done some other tests, so I will post them when I get a free moment. Thanks everybody for your help on this.

Boy, you guys are great. Now here is a few answers to your queries. Yes there is a large stairwell up to the second floor. And yes, the air handler is in the attic, and it is a slab on grade home, so all the heat vents are in the ceilings. We have left the thing running for a week, with the fan on, not on auto, and each day the temp reads about 67 to 70 depending on how warm it is outside. (we set the temp at 50 because if any higher the house is a sauna). The auxilary heat red light on the t stat does not come on. It seems like the heat pump unit itself has not been coming on ie the fan turning and making noise, but the heat vents always have air coming out of them. So I am assuming the fan is always on recirculating the whole house air. That being said, this is my first heat pump system, so I am abit over my head on this. I may have to bite the bullet and get the hvac techs back to do a thourough check and get to the bottom of this. Thanks so much for all of your insight.

Thanks for all your comments, I will definitely be getting another tech to look at our system, I knew something was not right, now I have to find out just what that something is. Thanks again for all your help

First time poster- We just bought a new house with a Lennox merit 13HPX heat pump and and CB(x)26UH(-R) with electric air handler furnace. the house is a two story. the furnace is in the attic. When we set the temp to 50 degrees F. and fan to recirculate, the house main floor will be between 67 and 70 degrees F. and the upstairs will be between 78 and 80 degrees F. We think we have the furnace fan working to take the heat from upstairs and recirculate it to the downstairs and even out the heat, but it seems like it is always the 10 degree difference, and when we go out side to look at the electric meter, even when the heat pump is off and it should only be the fan running, the electric meter is going very fast. I am assuming if it is only the fan running to recirculate, it should only be about 200 watts or so, but is sure seems like it is using a lot of power to just run the fan. Does this make sense,? we just had a technician check everything out with the heat pump and he says it all ok, and he told us how to see if the auxilary electric heat was running , but we are worried our power bill will be sky high, if there is more than the fan running. Does this make sense?
