Whats better for a furnace. Lets say you set the thermostat at 75 degrees.

Option 1. Let the furnace maintain the temperature throughout the day.

Option 2. Turn the thermstat down for the day and then turn it up at night when you get home.

My theory is let it run during the day. It seems that it would be easier to maintain the temp than to have to run for an hour or two to nock off the chill just so you can be warm for when you go to sleep.

So what say you?
 
Alright HVAC man here! Let it run all day, it isn't worth the amount it takes to catch up when you set it down. 75 is pretty high here but we usually don't cold like the midwest. I have been doing HVAC for 12 years and I have never believed the hype about programmable t-stats saving up to 33% on energy cost.
 
I am not a HVAC guy, but I do manage 40+ commercial tenants with constant HVAC issues. Here in Texas it is the summer temps that cause us the big issues with cooling during the day. If the tenant shuts off the HVAC during the night it will never quite catch up during the daytime hours. The programable thermostats don't save us any money, but it does make cooling more efficient. One way to look at it is that if everything in the office / house heats up to 80-85 during the night it takes quite a while to pull the heat out, I assume it would be the same with the really cold temps up north...
 
i was,in the old day, when i was a young man a HVAC man ,
so let me chime in here , get your self a good setback programmable thermostat ..

for 1 why heat or cool your house if you don't need to ,
2, A good state will save you money, and a good state will not let your house get cold to where it will need to work hard when it comes back on to get your home back to temperature!!!!!!! the thermostat wile in its away program will sense that its getting to cold or in the summer time to hot to bring your home back to temperature a the time you have it set for in its program, it will know to come on earlier so the home will be at the desired temp when it calls for heat

if you like your home at 70 degrees when your there ,you would set it to hold temp at 70 while the home is occupied, then when the home is not in use like if you go to work at 7am you set it to hold 65 degrees and you have it set to have the home at 70 at 3pm when you return.. now if it gets really cold out and in your home it will sens it and bring it back up to a tempeture that will be needed to have your home at 70 at 3pm without working hard

We turned the "central" heat down to ~62 last year. Then rolled out the portable radiators. We put one in each of the kids rooms for night time use, and moved ours from our room to the livingroom during the day. I can't say exact #'s but I know the wife was pleased with the drop on the bill. We kept plenty warm too...

Still haven't fired up the furnace for season yet.
 
sorry,i think we are talking heat,,
but
cooling a home works by removing humidity first , it don't matter what size your units is if you allow the humidity to rise the harder your unit will work! in trying to cool it back down. you must remove the humidity before cooling can start, your coil is a evaporating coil it pulls the heat from the home (humidity) and removes it to the out side where it is dissipated by way of the condenser fan . so to say the unit is small is misleading! the higher the humidity is the harder the unit works!!! properly sized or not.a good thermostat will keep this from happening when set to run on program witch can be set 4 times a day 7 days a week,
heat or cooling mode /ubbthreads/images/graemlins/grinning-smiley-003.gif if a ac unit is to small it will not work or cool the home ,but if humidity is high in the home the right size unit will not work till the humity is removed

the man need a good programmable thermostat is all , looking about 100 bucks or so and very easy to install and i can talk you though it over the phone if you like, Honeywell 4000 or up

That is why you get a variable speed unit that has advanced humidity options. Here in the south we have very high humidity. An oversized unit dosen't run long enough to remove the humidity. Our biggest problem here is people don't do routine maint. like your supposed to and some change their filter once a year.
