I know you guys don't like DIY posts, but I'm hoping this one is ok. It relates to thermostat problems.
Furnace in my new home seemed to be working ok until last night. Here in indy, we got a blast of storms, wind and cold... I suddenly noticed it very hot in the house, with most of our rooms measuring 80 degrees despite having the thermotat set at 74 (yeah we like it warm, but not 80 degree warm).
Since it had been working all fall flawlessly, and I had a tech out to inspect/service the furnace back in september, I got curious as to what would be causing this and broke out a thermometer. All my rooms read 80 degrees, even the hallway where my thermostat is at, but the thermostat was reading 74.
I found some posts here about air leaking through wiring holes in the wall behind the thermostat, and sure enugh that's what the problem ended up being. I plugged the hole up, and instantly my themrostat was reading 79.
Saved myself a service call with a simple fix.
So I wanted to say thanks for the wealth of information here, that can help homeowners make informed decisions, and with small easy fixes.
While searching though, I found alot of posts about cycling and how it relates to thermostats. Mine is digital, and doesn't have a heat anticipator or cycle setting on it (I think it's a cheap one). Anyways, it seems to be cycling as follows; about 12 minutes off, 10 minutes on. thermostat is set at 74, outside temp is 30. Humidity in house is 38%, outside is 62%. heat is 80,000btu high efficiency furnace.
This is my first home with central air heating, so I'm not really sure how it should be performing. It seems fine to us, but reading through many of the posts here really makes me wonder. Should we look into a better thermostat where we can set the cycles per hour? or are we running ok?
