Obstructions that block exhaust gasses are dangerous and can cause high levels of Carbon Monoxide buildup. Contact Martino HVAC and have our technicians take a look to make sure your exhaust is sufficiently high to clear future snow falls.  If your furnace exhaust was buried in snow and you've cleared it, but your furnace still isn't providing heat, follow these steps: Check the thermostat: Ensure that the thermostat is set to the correct heating mode and temperature. Sometimes, the issue may be as simple as an incorrect thermostat setting. Reset the furnace: Turn off the furnace switch, usually located near your furnace, and wait for a few minutes. Then, turn the switch back on to reset the furnace. This can help clear any error codes or issues related to the blocked exhaust vent. Check for error codes: Some furnaces have LED indicator lights or display panels that show error codes. Consult your owner's manual to understand what these codes mean and if there are specific troubleshooting steps to follow. Inspect the air filter: A dirty or clogged air filter can cause your furnace to overheat and shut down as a safety measure. Replace or clean the air filter if necessary. Relight the pilot light: If you have a furnace with a pilot light, check to see if it's lit. If not, follow the instructions in your owner's manual to relight the pilot light. When the exhaust vent is blocked by snow or debris, the combustion gases, including carbon monoxide, cannot be properly vented outside, causing them to accumulate in your home. Carbon monoxide is dangerous because it can lead to CO poisoning, which can cause symptoms such as headaches, dizziness, nausea, confusion, and even death in severe cases. Blocked vents also increase the risk of fire or damage to your furnace system. To reduce the risk of carbon monoxide buildup and poisoning in your home, follow these precautions: Clear snow and debris: Regularly inspect and clear any snow or debris from around your furnace exhaust vent, especially after heavy snowfalls or storms. Install CO detectors: Install carbon monoxide detectors on every level of your home and near sleeping areas. These detectors will alert you if there is a dangerous buildup of carbon monoxide in your home, allowing you to take action before it becomes a serious health hazard. Schedule regular maintenance: Having your furnace inspected and maintained by Martino HVAC's technicians on a regular basis can help prevent potential CO issues. Our technicians will check for any problems that could cause carbon monoxide buildup, such as cracks in the heat exchanger or issues with the venting system. Be aware of symptoms: Familiarize yourself with the symptoms of CO poisoning and take action if you or a family member experiences them. If you suspect CO poisoning, immediately leave the house and call emergency services. If you've cleared the snow from your furnace exhaust vent but are still concerned about the risk of carbon monoxide buildup or your furnace is not providing heat, contact Martino HVAC. Our technicians can perform a thorough inspection and ensure your furnace is operating safely and efficiently.
