There are limits set by the manufacturer on how hot the furnace can run. This is known as the heat rise and it`s listed on the furnaces ID tag. Have a qualified tech do a heat rise test on your unit and if you are on the low end(meaning you have room to go up) have him slow down the blower. If you don`t have the room after the test don`t do it. Ideally you should be operating around the midpoint of the listed limit which will leave you room to go up and still remain safely within the limit as the filter gets dirty
Check the outlet gas pressure with a manometer to see if the burner is operating in the manufacturers specified range.
I would also check that you have correct return air, the warm air has to have somewhere to go and must circulate. Check the temperature of the room at the ceiling and at the floor if it is different it may be an airflow issue and you may have to add another return air duct. Contact a heating contractor and have them balance your airflow and check the fan speed settings on your the furnace board. Many furnace fans are installed to run on high for use with AC units, while for heating mid fan speeds are usually ideal.
What else can I help you with?
Can a bad thermostat cause the heat to blow cold air?
Yes, a faulty thermostat can cause the heating system to blow cold air. If the thermostat is not functioning properly, it may not signal the furnace to turn on and produce warm air. It's important to have a professional inspect and replace the thermostat if needed to ensure proper heating.
What is A furnace with a vertical air flow and the blower compartment located on the top of the unit called?
It is called an upflow furnace. This type of furnace takes in air at the bottom, heats it, and then releases it through the top vents.
Is it better to blow air in or out for optimal ventilation?
For optimal ventilation, it is better to blow air out.
What is the primarily function of the Forced air furnace?
The primary function of a forced air furnace is to heat air, which is then distributed throughout the home via ducts to provide warmth to the living spaces. This type of furnace uses a blower to push the heated air through the ductwork system, ensuring consistent and efficient heating.
What type of heat transfer occurs when a hot air furnace heats our home?
The type of heat transfer that occurs when a hot air furnace heats a home is primarily convection. The furnace heats the air, which then circulates throughout the home, transferring heat to the surrounding objects and raising the overall temperature.
Why does a gas furnace only blow cold air?
Because you set it that way
Why does my furnace blow cold air and then hot air intermittently?
Your furnace may be blowing cold air and then hot air intermittently due to a malfunctioning thermostat, a clogged air filter, or issues with the furnace's ignition system. It is recommended to have a professional HVAC technician inspect and repair the furnace to resolve the issue.
Why would a furnace blow cold air instead of warm air?
A furnace may blow cold air instead of warm air due to issues such as a malfunctioning thermostat, a clogged air filter, a problem with the pilot light or ignition system, or low fuel supply. It is important to troubleshoot and address these issues promptly to restore the furnace's proper functioning.
Why does the furnace blow cold air instead of warm air?
The furnace may blow cold air instead of warm air due to issues such as a malfunctioning thermostat, a clogged air filter, a problem with the pilot light or ignition system, or low fuel supply. It is important to troubleshoot and address these issues promptly to restore the proper functioning of the furnace and ensure it blows warm air.
Why does gas furnace blow cold air?

Why does the fan on my warm air furnace blow cold air?
Either the fan is set at too high a speed or the burner did not light.
Why does your gas furnace blow black smoke in the house?
# Why doe the gas furnace blow black smoke?
What does cfm refer to in furnace installation?
Cubic Feet per Minute. It refers to the volume of air the system can blow.
What should the air temperature be from the vents with the heat setting at seventy two degrees?
It depends on what your heat source is. An electric or petroleum fired forced air furnace will blow high volumes of air that is much hotter than 72 degrees Fahrenheit (perhaps as high as 90-100 degrees) for short periods of time. A heat pump, however, will generally blow air that is nearer the set temperature at lower volumes and for longer periods of time.
How do I choose the best furnace for the environment?
Gas furnace are more energy efficient in my opinion. Electric furnaces use forced air and when you blow air over an electric element, it takes more energy to keep it hot.
Furnace only blow cold air?
If the furnace only blows cold air the pilot light may be out. It may also be a fuse that has blown. However, you may need to contact a licensed electrician to find the problem.
Why does the home gas furnace blow cold air?
Perhaps the pilot light is out and the gas has been turned off at the valve.
