When I woke up this morning the house was very cold, I checked thermostat to make sure it was still on, and it still displayed the heat as being on, with temperature set at 68 degrees. However, it was showing a house temperature of 59 degrees. I tried playing with temperature, nothing changed, didn't hear furnace kicking in.
I checked furnace and didn't notice anything obvious, however don't know much about furnaces. I was late for work so didn't have a lot of time, but quickly opened furnace door didn't see pilot light anywhere so just put door back on and had to leave for work. The switch on wall by furnace was still turned on as well.
Do I need to call a technician or is there something simple it could likely be? The house was just built two years ago, so furnace is only two years old. Here is the model numbers listed on the booklets that were on the furnace.
Carrier Model 58MCB
There's another book with a different model number
Carrier Model 24ABB3 / 24ABC6.
It's a gas furnace.
Any suggestions on what I could do to avoid a technician fee?
Thanks
