A good furnace is an important part of home ownership. The best way to achieve this is through regular maintenance performed by an HVAC expert.
Make sure the circuit breaker is not at risk of being tripped. This safety measure was designed to protect against carbon monoxide.
Check the Thermostat
The thermostat is an electronic device that transmits signals between sensors in your home and the furnace and tells it when to turn off or off. It also has a display screen that shows you information about your heating schedule and current indoor temperature. If your display is blank it means that you need to replace the batteries in your thermostat.
Some thermostats are powered by batteries, others by the circuit breakers in your home or the grid. If the latter type of thermostat is experiencing problem, it may emit an unrelenting hum and you’ll hear a clicking noise when a signal is received by the furnace.
A constant humming sound could indicate that there is water in your furnace. The problem could be due a clogged condensation drain or a broken condensate pipe. A qualified East York HVAC specialist can determine the cause and fix the problem quickly before it worsens.
If the blower and furnace are not operating, it could be that the thermostat is malfunctioning. The thermostat could be disconnected from the control board. The fan would not receive enough power to distribute the air.
To solve the problem, remove all wires from the furnace using a screwdriver. Connect the wires that aren’t bare with the white and the red (the standard colors for power and heat).

The pilot assembly can be removed by removing access panel from the furnace. To restore gas, you need to push the reset button. Take care to remove the assembly carefully, as natural gas is highly flammable. You should check the gas valve before you move on to other troubleshooting.
Check the Blower
Air will flow through your home’s ductwork once you start your furnace. It could be that your furnace isn’t blowing enough. Insufficient air flow may also affect the humidity of your home.
It is easy to check the blower by simply turning off the system and searching for the door in the cabinet. After that, remove the panel and open the door. The rotor’s attachment is by snap-clips or screws. Replace the rotor by using the screwdriver in your toolkit or pliers.
Close the panel after replacing the rotor and re-energize your system. The flame sensor in your furnace may be malfunctioning if the blower is still not working. This safety feature checks for flames to determine if the gas valve can be opened. Over time the metal rod can become coated with dust or carbon deposits caused by combustion. If it does not work properly, the system will be turned off to ensure safety.
By examining the blower’s door for damage, you can tell if it has a faulty flame sensor or if its motor is damaged. In addition, you must examine the ductwork in your home for leaks and moisture accumulation. You may have a system that is not operating properly if you see any of these signs. It may require repairs or replacement parts.
A large utility bill is another sign that your system may not be operating correctly. Utility bills are a good indicator of how much energy your system uses. It’s possible that your energy bill is much higher than normal. This could indicate that your heating unit is not working properly.
Check your filter
A furnace filter needs to be replaced approximately every three months to six. A high-efficiency filter that is clean can help reduce the cost of electricity and also increase the lifespan your furnace. A clogged airfilter can reduce the circulation of the air through the exchanger, which causes it to heat up. The computer will shut down your system if the heat exchanger has been overheated more than four times.
The blower can be hindered by a dirty filter. Remove the filter, and listen for air moving through the vents. It’s time to change the filter if you can’t hear anything.
In a home inspection, you can look for other things that indicate the furnace isn’t operating correctly. For example, a strong scent is one sign. It could indicate poor combustion that is producing carbon monoxide. You can test your furnace pressure by checking the gauge.
When it takes more than one attempt to turn on the furnace, this could be a sign that something is wrong. The pilot light could not be lit. It could be a straightforward fix. A technician will be able to inspect the pilot flame and thermocouple in order to identify the cause.
You should look for safety features, such as a door switch or service panels that stop the system from running if the panel was opened or taken off its hinges. Also, make sure the panel is securely fastened to its frame. It will help keep away children and intruders.
You should look for an accessible way for service technicians and homeowners to access your air handler if the furnace is located up in an attic. You should look for signs of moisture, and any biological growth in the duct that runs to the outside air intake.
Check the filter compartment as well as the opening and the panel of access. All accessible ductwork should be examined to check for sagging or air leaks as well as loose or missing insulation. Listen for a whistling or rattling sound, as this indicates that the ducts may not have been sealed properly.
Verify the Combustion Chamber
Furnaces create warm air through a heating process that involves burning fuel and then blowing it into your house through ducts. The combustion fumes are expelled by the heat exchanger after they have cooled. If there’s a problem, you may find that your home is contaminated with toxic carbon monoxide. By identifying issues early and maintaining regular maintenance, you can prevent this.
A furnace that is functioning properly will produce a whirring noise. If it makes other sounds like banging or rattling that could be a sign of a malfunction. A professional can find the source of these sounds, and correct them prior to becoming a major issue.
In addition to making loud noises A damaged furnace may produce other signs, such as a clogged burner or exhaust vent. Over time, dust can cover the flame sensor. This can stop it from sensing the pilot lights and igniting a furnace. This could result in the system cycling on and off repeatedly, instead of continuously running at full capacity.
Circuit breakers that have been tripped are another indication of a potential problem. This switch controls power to your furnace, and if it gets turned off, the system won’t be able start. Switch on your circuit-breaker if you see it has been turned off.
You can also check the combustion chamber to determine whether it’s in good condition. You should be able see the flame underneath the ignitor. If the part is glowing red, or furnace and air conditioner combo if it has any other marks on it, then you should have an expert replace it.
The flue pipe that delivers combustion gas outdoors can be blocked by anything from a bird’s nest to a fallen branch. Carbon monoxide may enter your house as a result. That’s why a carbon-monoxide alarm is necessary. An HVAC technician can seal the source of a leak and replace the flue pipe if you have a leak.
