Question about Heating & Cooling
Furnace will beep once approximately every 25 seconds several times and then stop for a time before starting again. (About 12 hours ago, I had to reset a limit switch and operation seems normal except for beeping described)

If you know where the high limit switch is you can always cut the two wires and wire them together causing the limit to close. But what you have to watch out for is why the high limit is not closing. That means in your return air either you have a dirty return air duct, dirty filter, or you don't have all your registors open to allow the heat to escape the heat exchanger. Just watch over riding the system. The high limit switch should either be on or behind the blower, in the middle of the system right under the heat exchanger. any other questions about hvac just ask.

If the unit is around 6 years old then it could be the combustion air motor. If the unit is older then you need to inspect the heat exchanger for signs of cracks. Take the top off the unit to inspect. Check to see if the metal around the reset is hot and if it is then the switch is doing it's job. If the heat chamber is cracked then turn the gas off, because your home will have CO. This can kill you.

Open the two side panels. The filter is at the bottom held down with a wire spring. Release the spring and the filter can be removed.

Dang that simply sounds to me like a contaminated flame sensor. Junk gets on the sensor and the resistance won't change quick enough for the control to confirm ignition. Get a dry brillo pad and clean that ******. here is a video:
