My forced hot air furnace turns on and off every 10 minutes, (on for 10, off for 10) in order to maintain the temperature, but driving up by gas bills. Yet if I manually turn the thermostat on for 10, and off for 25, I can still maintain the same temp. I am not actually losing heat as fast as I add it. So I'm thinking I have a faulty thermostat??? Also it may be the location of it - it is at the base of the staircase leading upstairs and while that is an inside wall, it is the same wall as the staircase leading up from the basement which is not heated. Could this be wreaking havoc with "perceived" temperature swings sensed by the thermostat? Help!
There are a few things that can cause this problem. The most common is the hole behind the thermostat for the wiring was not covered up when the thermostat was installed. The thermostat will sense the air in the wall space or the basement if it is open to the back of the wall supporting the thermostat. Turn off the power to the air conditioner if attached and the furnace, remove the thermostat from the wall and seal up the wiring hole with duct tape. Insure the thermostat is mounted level when reinstalled. The thermostat should be mounted to sense the return air to the furnace, if the stair well leads upstairs, warm air rises, so keep the upstairs close to the same temperature as down stairs or move the thermostat and install a door to block air movement to the upstairs. There is a heat anticipator on the thermostat, the setting for it is in the installation manuel. For most gas furnaces it is .8. It is very easy to short out the thermostat when making this adjustment, so always have the power off.

Sometimes it is difficult to keep your home cool in the hot summer months. Also, some areas of your home may still be hot where other areas are too cool. Try this method to keep your home cool evenly throughout. Before you get started make sure your furnace filter is new. This will allow for maximum air flow.
If your living space is a single floor plan:
Turn the air conditioning on
Switch the furnace fan from auto to on.
Measure the temperature in each room.
Close the vents by about half in the cooler rooms
This will force more cool air into the warmer rooms.
Keep adjusting the vents until all the rooms have the same temp.
If your living space is on more than one level:
Turn on the air conditioning.
Switch the furnace fan from auto to on.
On the lowest level of the house close half of the vents that are the closest to the stairs.
This will force more cool air to the top floor where it is usually hotter.
Cool air will sink from the upper floors which will keep the area near the stairs cool.
Measure the temperature in all the rooms.
Keep adjusting the vents until you have a nice even temperature throughout the house.
I found that leaving the furnace fan on all the time will keep your home evenly cool and comfortable. You may have to replace your furnace filter once a month due to the increased air flow. It will be well worth it in a cooler, more comfortable, and more energy efficient home.
As your gas furnace or other type of furnace heats the air in your house it will be forcing the moisture out of the air. To maintain the proper comfort and to keep things from cracking from lack of moisture you need to install a furnace humidifier.
Furnace humidifiers offer many health benefits. They help to relieve the irritation of breathing dry air. More humidity in the air has shown in studies to lead to healthier lungs and fewer illnesses.To many people, another very important benefit of installing a good furnace humidifier is that the addition of more humidity to the space during cold-weather months allows for you to lower your temperature setting on the thermostat while still maintaining comfort.
If you are already looking for a furnace humidifier, you are probably familiar with many of the great benefits of installing one in your home or office. A good furnace humidifier will also help alleviate some symptoms associated with asthma or allergies as well. A good furnace humidifier can also help you to prevent cracks in your precious wood. Another great benefit of installing a furnace humidifier is that it will help eliminate static electricity.
The three most common types of humidifier are bypass furnace humidifiers, the power spray furnace humidifiers, and also steam furnace humidifiers.The bypass humidifier seems to be the most common furnace humidifier is the bypass humidifier.
All of the different types of humidifiers need to have a lot of maintenance. On the pad type humidifiers you need to clean or change to pads often. On spray type humidifiers the nozzle and pad will need to be changed or cleaned yearly. On the best types of humidifier is the steam furnace humidifier. They produce the most humidity but are very expensive and do require more regular maintenance and upkeep then the other types of humidifier.
A humidifier can be a fantastic addition to your hot air heating system. The type of humidifier that you need to have will often be dependent on the size of the space you are planning to serve. Also, do you need precise control or not? Overall a humidifier is often a must have item if you are heating with hot air heat. Dry air is not any fun and causes many problems. Put up with the time you will need to invest in cleaning and servicing your humidifier. Having the proper amount of moisture in your house will pay you back many times over.

[HVAC] My gas furnace cycles off every 6 minutes. ... This cycle will repeat a fewtimes, then usually after the second or third time everything ... How long is it after the big blower cuts on that the gas shuts off? ... Turn the furnace on, once the inducer blower is running you should read 0 volts (switch is closed).
Watch your furnace when you turn the thermostat up...make sure to record everything that it is doing. If you have an induced draft, forced air system, then the heat sequence of order should go like this... Initial call for heat from tstat, Inducer vent motor turns on-pulls in the pressure switch, circuit board sends power to igniter whether it is spark or hot surface, then gas valve opens. Flame sensor senses flame, burner stays on, and blower motor kicks in to heat the space. If you notice any variance from this, then something needs to be checked by an HVAC Service Tech.
If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts
right back off, then you need to clean your flame sensor with light sand paper
or steel wool. You might need a new flame sensor, but most of the time they can
be cleaned an will work well after cleaning.
It sounds like you may have issues with the furnace. A qualified professional can go over the system and the house to let you know if the system and unit are properly sized. The poor performance of a furnace can be a sign of carbon buildup in the furnace.
Good luck, hope this helps.
not familiar with that particular model but on virtually every type and style of furnace i have worked on in the last 21 years. the fan is delayed. usually the burner lights then 3 to 5 minutes later after the heat exchanger has gotten nice and hot the fan comes on and blows nice and hot air. on old furnaces there was and is a switch usually on the upper right side of the furnace bulkhead that has a spring like device that heats up and rotates till it makes a set of contacts that turn the fan on. if it gets to hot the set of contacts breaks the power to the gas valve and shuts down the burner. as the furnace cools down on shut off there is a third set of contacts that open to turn off the fan so you don't get a draft. sometimes the stat can be wired up wrong, and it will bring the fan on right away ,and air will be cool and drafty till furnace catches up.
