Why Isn’t My Furnace Working?
Ogden-area homeowners are accustomed to the cold, snowy winter weather, and they dress accordingly when heading into the great outdoors—but if you find yourself layering up indoors, there may be something wrong with your heating system. If your furnace is underperforming or has stopped working altogether, it can be more than just an inconvenience, as certain issues may pose a threat to the health and safety of your home and family. There are a number of reasons your furnace may not be working as it should, but regardless of the problem, the experienced professionals at Mountain Air Conditioning & Heating can provide a solution, with expert diagnosis and repair to restore comfort to your home.
Signs Your Furnace Is Not Working
Routine annual maintenance can help to keep your heating system operating at peak performance, but as your furnace nears the end of its life, you are more likely to experience a decrease in efficiency and an increase in repairs. Contact Mountain Air for fast, efficient furnace repair if you experience any of the following:
System Won’t Turn On
If your furnace won’t turn on or won’t stay lit, you will need to resolve the problem quickly to avoid potential damage to your plumbing or electronics and to ensure the comfort and safety of your family. While the issue may be something as simple as a tripped breaker, dead batteries in your thermostat, or the power switch to the furnace being in the “Off” position, it could instead be something more serious that requires the services of a licensed, certified professional for furnace replacement or repair.
Failure to Reach the Desired Setpoint on the Thermostat
Does your furnace run and then turn off before your house is warm? This is a common issue among Ogden-area homeowners and may be caused by any of the following:
- Faulty thermostat
- Incorrect setting on the thermostat
- Malfunctioning, blocked, or dirty flame sensor
- Lack of airflow around or inside the furnace, or within the ductwork
- Dirty air filter
If you are unable to resolve the issue after checking the thermostat and the air filter, call the experts at Mountain Air for a more detailed diagnosis and repair.
Supply Vents Blowing Cold Air
The last thing you need when the winter winds are howling outdoors is a cool breeze from the supply vents inside your home. If your vents only periodically blow cold air, check the thermostat settings to see if the fan is set in the “On” position, which causes the furnace blower to run constantly even during the time the furnace is not generating heat. Readjust the thermostat to “Auto,” and the blower will only blow warm air, and only during the furnace operation.
Cold air coming from your vents may also be a sign that the furnace pilot light is out or that the furnace is overheating, triggering the limit switch to turn off the unit to prevent damage.
Strange Noises or Odd Smells
Loud, persistent, or sudden noises such as banging, clicking, squealing, grinding, or hissing coming from your furnace are all signs that something is amiss and an immediate call for repair is warranted.
The smell of rotten eggs is caused by a natural gas leak and is cause for alarm. Shut off the power to the furnace immediately and evacuate your home if you detect this odor, then call Mountain Air for emergency furnace repair.
Flickering lights, tripping breakers, the smell of burning wires, and buzzing sounds during furnace operation are all signs of electrical issues that, if left unattended, may lead to a fire or injury. Turn off the furnace if you notice any of these signs and contact the certified professionals at Mountain Air for efficient furnace repair services.
Troubleshooting Your Furnace
Whether your furnace stops running outside of the scope of regular business hours, or you want to save some time and aggravation by troubleshooting your heating system before calling for repair, here is a list of basic furnace issues you can check that you may be able to resolve on your own:
While it may seem obvious, your furnace may not be working because the power is turned off to the appliance. Before calling a licensed contractor for furnace repair, check to ensure the furnace switch is in the “On” position, and that the electrical breakers have not been tripped. In the event that the problem originates at the electrical panel, reset the breaker, but if it trips again, leave it off and call for furnace repair.
The thermostat must be set to “Heat” or “Auto” in order for the furnace to work, and if you forgot to make the switch between heating and cooling at the beginning of the season or the setting has been inadvertently changed, making the adjustment should resolve the issue. If not, try replacing the batteries in the unit or restarting your smart thermostat by removing it from the wall and then reattaching.
Dirty Air Filter
Your air filter should be changed on a regular basis to ensure optimal furnace performance and efficiency, or the filter may become clogged and hamper the flow of air. In addition to the lack of comfort and reduced quality of your indoor air, a dirty filter can place unnecessary stress on system components and lead to premature failure or costly repairs. Change your air filter every four to six weeks during peak heating season or more often if needed.
A pilot light that has been extinguished by a draft will need to be relit in order to restore the operation of your furnace. If you feel comfortable, follow the instructions listed in your owner’s manual or on the side of the appliance to relight the pilot, or call Mountain Air for assistance.
If some rooms in your home are hotter or colder than others, there may be a problem with your ductwork. Check that all your return and supply vents are open and unobstructed by furniture, draperies, plants, or other materials, and inspect any visible ductwork in your basement or crawl space for signs of damage, disrepair, or disconnection.
