What is that smell every year when I start up my furnace?
Typically over the summer when the furnace is not in use the heat exchanger inside the furnace gets coated with a layer of dust and when you start up your furnace in the fall the heat exchanger burns this dust off which is what you are smelling. This is normal for most heating equipment that has not run for several months and does not harm the equipment. As for indoor air quality concerns I would have to say that it may be a good idea to open some windows to be on the safe side.
How do I light the pilot on my furnace?
Most modern furnaces today no longer have a standing pilot light like the ones seen on gas water heaters. Most furnaces today will either have an electronic spark ignition or a hot surface igniter system. But if your furnace does have a standing pilot light the best advice is to follow the instructions on the stickers and labels on the furnace itself. If your pilot will not stay lit then you need to clean or replace your flame sensor.
Why is the LED light flashing on my furnace?
If your furnace status LED is blinking a steady single blink this usually means the system is either in stand by mode or is receiving a call for heating or cooling. If the LED light is blinking rapidly more than once and then pauses and does more this usually indicates the furnace has an issue and some sort of failure or a safety device has tripped. The codes can be difficult to read unless you read them all the time but they normally refer to two specific numbers that correspond to a troubleshooting chart in the manufacturer manual or sometimes right on a sticker on the furnace door. Each code usually tells the technician what to look for on the system and in most cases there can be more than one thing to check.
