Why Is My Furnace Running But Not Blowing Heat?

Top 5 Reasons Why Your Running Furnace Is Not Blowing Heat

Furnaces have always been known to be the most popular way to heat our homes. Our home furnaces can be considered one of our household’s most important units, especially in the winters. However, lack of proper maintenance can lead to inconveniences and the unit not performing well. But you have nothing to worry about if problems occur to your furnace because Best New York Heating and AC Repair is here to provide you with the best furnace maintenance services.

Furnaces, like every appliance and system at home, require regular check-ups, and cleaning them from time to time can also help a lot. However, despite our efforts to keep it in top working order, there are issues with our furnaces that hinder its general performance and functioning.

Determining the issue should be our top priority to know what action to do next. As furnaces can be complicated to inspect due to the possibility of fire and other dangers occurring should a mistake happen, it is highly recommended to have professionals handle them for you and your family’s safety.

Here are 5 possible leads why your furnace is not blowing hot air:

1. Dirty air filters – Have you changed your furnace filter recently? Check disposable air filters monthly and replace them if they’re unclean. A dirty air filter affects more than your home’s air quality. Air filters cause various furnace issues and inhibit furnace return airflow. If you have cold air, try changing the air filter. If that doesn’t work, call a professional HVAC specialist immediately. 

2. Thermostat setting – The problem may not be your furnace if you receive cool air rather than warm air. There could be a problem with the thermostat. Plus, you never know who in the household may have made “unauthorized adjustments” to the thermostat.

• Change the thermostat to “hot” from “cool.”
• Set your fan thermostat to “auto” instead of “on.” If “on,” the blower fan may run even when the furnace isn’t heating the air to the desired temperature.
• Dust off the thermostat panel. Unclean thermostats can fail.
• Replace battery-powered thermostats. Some thermostats work completely on battery power, while others use the home’s primary power. Dying batteries can cause the thermostat to send the furnace inaccurate temperature data.
• Make that the thermostat is securely mounted and no wires are loose or broken.
• Note the thermostat’s air temperature. A thermostat measures surrounding air temperature. Is the thermostat in a warm spot? The thermostat will apply that temperature to the remainder of your home, resulting in colder air.

3. Gas supply valve (for gas furnaces) – Have you had any recent repairs done lately? Someone may have turned off the gas supply valve to make repairs and then forgotten. Without gas, your furnace can’t heat. If the gas valve handle is parallel to the pipe, it’s on. Off, the handle is parallel to the pipe. Call a specialist immediately if this doesn’t work, and you smell gas. Gas leaks are very dangerous.

4. Pilot light (for gas furnaces) – Problems with your gas furnace’s pilot light can cause it to emit frigid air. Most modern gas furnaces lack a physical pilot light in favor of an electronic pilot igniter and flame sensor. Repairing or replacing them is the responsibility of a professional HVAC specialist. Unclean or clogged pilot igniters can inhibit furnace ignition. If you know how to switch off the furnace’s electricity, remove the front panel, and locate the ignitor, you may check for a dirty ignitor.Once you’ve confirmed that the gas line is safe (by calling the gas provider), relight the pilot light according to your unit’s instructions. Call a professional if it won’t remain lit. Possible issues with the thermocouple or ignition system may be at hand.

5. Check air ducts – Your heater blows hot air into certain areas but not others. Does it appear as though the airflow is weaker than you recall? Ventilation or ductwork issues are likely to blame. Check the air vents to ensure the dampers align with the ducting. This may indicate that your furnace’s dampers are fully open, allowing maximum ventilation. Continue to receive chilly air from the vents? You may have faulty ductwork. If you suspect an issue with your ducting, you should consult a specialist in the field.

7 Signs Your Furnace Needs Cleaning

We all want our furnaces to always work in their best capacity. A furnace is highly active equipment that requires periodic cleaning. Filth and grime in your furnace can harm it over time and represent a safety issue in some instances. Failing to clean your furnace can lead to many concerns, some of which might compromise indoor air quality and jeopardize your family’s health. By inspecting your furnace and air filters monthly, you may uncover most of these issues before they become severe. However, it is best to have experts handle the job. Best New York Heating and AC Repair guarantees to offer professional and satisfying furnace maintenance services for your furnaces at home.

So, before you call for assistance with the experts, how do you know whether your furnace needs to be cleaned? Here are 7 helpful signs to know when you need furnace cleaning:

1. Struggling to maintain your wanted temperature

Given that the sole purpose of your furnace is to warm your home, it isn’t very pleasant when this is not functioning. If you have any of the following problems, you may need to remove debris and dust:

• Inconsistently colder temperatures in some rooms than in others
• Your furnace is not maintaining the temperature on your thermostat.
• You have no heat whatsoever.
• Your heating system is cycling on and off too frequently.
• It requires too much energy (and an excessively expensive energy cost) to reach the desired temperature.

2. Emitting strange odors

Have you ever followed a strange odor throughout the house? It could be your furnace, and a thorough cleaning could solve the problem. If you detect rubber, smoke, or oil odors while your furnace is running, it is likely time for a cleaning. Allowing these odors to persist without cleaning can lead to a potentially dangerous situation. Don’t worry if you smell dust when switching your furnace since this is normal.

3. Yellow or orange furnace flames

The flame color of your furnace is an easier indicator, among others. The flame of a properly running furnace should be blue. If it’s yellow or orange, the gas-oxygen ratio is off. This may be due to a filthy burner; thus, cleaning is required. 

4. Rising energy bills

Is your energy bill particularly high even though you haven’t used your furnace more than usual? A buildup of accumulated dirt causes an overheated furnace. As a result, your furnace will use more energy and heat your home less effectively.

5. Furnace noises

A homeowner’s worst fear is hearing strange noises from their home. However, a simple furnace cleaning may be all that’s required. If you hear a loud bang when turning the furnace on or rustling and howling, these noises can be caused by clogged air filters, filthy burners, or a limited fuel supply, among other things.

6. Piling dirt and debris

If things aren’t cleaned regularly, they will eventually become dingy. If your furnace is clogged with hair, dirt, grime, and dead skin cells, it’s time to clean it. Examine the HVAC system’s air filters. Replace or clean them if they’re caked in dirt and dust, and then review them in a few days. If your just installed or cleaned air filters are already unclean, it’s time to give your furnace a good scrub.

7. Less indoor air quality

You breathe it in; dust, mold, filth and everything else your furnace or ducts are full of. A musty odor in the air or the need to dust more frequently may be signs of something wrong. Even in the winter, allergy symptoms can occur. If so, a simple furnace cleaning could improve your interior air quality.

See the list below for the signs you’ll need to know when your furnace needs cleaning.

• Struggling to maintain your wanted temperature – if your furnace is having trouble maintaining the temperature on your thermostat and inconsistent temperatures in different parts of the house, then you need to clear your furnace of dirt and other debris.

• Emitting strange odors – if your furnace releases weird odors, it must be a clear sign of a dirty furnace that needs to be cleaned up immediately.

• Yellow or orange furnace flames – yellow or orange flames mean that a dirty burner off causes the gas-oxygen ratio, which can be very dangerous; hence cleaning is required.

• Rising energy bills – a buildup of accumulated dirt causes an overheated furnace which uses more energy and heats your home less effectively.

• Furnace noises – loud banging, whistling, howling, and rustling in your furnace indicates clogged air filters, filthy burners, or a limited fuel supply.

• Piling dirt and debris – clogged with hair, dirt, grime, and dead skin cells can cause a furnace to become dull and less effective, which is why it should clear any unwanted dirt.
• Less indoor air quality – breathing in dust, mold, filth and everything else your furnace or ducts are full of can result in serious health-related issues and allergies that can be prevented by regular cleaning and maintenance.
