A furnace is designed to provide reliable, consistent heat throughout the winter. So why is yours blowing cold air instead of warm air? This is actually a fairly common problem for Chapel Hill, NC, heating systems, and Boer Brothers Heating & Cooling has some tips on how to address it.
Check your Chapel Hill thermostat
The thermostat is often a good place to start when troubleshooting an HVAC issue. Specifically, the AUTO and ON settings on your thermostat will determine whether your home is comfortable this winter. The ON setting on your thermostat causes the fan that transfers air from the furnace to run continuously. Seems normal, right? Well, this causes cold air to circulate when the furnace isn’t producing heat. Make sure your thermostat fan mode is set to AUTO so that the fan only blows warm air through your household.
Is your furnace pilot light on?
Natural gas or propane fueled furnaces use pilot lights for ignition. Therefore, the furnace will cease to generate heat if the pilot light flame is blown out. If the pilot light won’t relight, there is most likely a problem with the supply of gas fuel. Check to see if the fuel supply valve on your furnace is turned on. If it’s on and you still have no heat, check other gas-operated home appliances like the stove or clothes dryer. Natural gas and propane companies in the Triangle area periodically perform repairs and tests on supply lines, and this can result in a temporary stoppage of the gas supply to your home.
HVAC system cleaning by Boer Brothers Heating & Cooling
Regular cleaning is one of the most important aspects of proper HVAC maintenance. Dirt and grime that clogs furnace components ensure poor performance for your heating system. Clean or change your filter at least once a month for efficient furnace operation. And don’t forget about the ductwork. Dust, particles and debris accumulate in the ducts over time, creating clogs that disrupt airflow and damage the duct system. This leads to cracks and holes in the ductwork, allowing cold air from the crawlspace or attic to enter the ductwork and circulate throughout the living spaces of your home. If you haven’t had your heating system inspected this fall, you could potentially have a defective furnace come winter.
