Furnace cycling?
I've noticed that my furnance runs about every 5 minutes or so. Is this considered cycling? I've got a Honeywell programmable thermostat.
I checked the Honeywell site, and they said this:
"For instance, gas or oil forced air systems have a recommended cycle rate of 6. With a cycle rate of 6, the heating system, at a 50% load, will cycle 6 times per hour. This breaks down to about 5 minutes on and 5 minutes off. Again, the actual on and off time of the heating system will vary as the load on the heating system varies."
So according to this, the 5-on, 5-off would make sense. I can't change the cycle rate, but I'm assuming that it is a cycle rate of 6.
My friend said that he thinks the furnance may be too big, which is why it is cycling (100,000 BTU for about 1900-2000 sq ft or so - I don't know the exact size).
Also, the duct work just above the furnace itself gets REALLY hot when it is running. The same friend suggested that they might not have cleaned that area when they replaced the furnace (2 year old furnace).
Thoughts?
