Throughout fall, winter, and spring, chilly weather persists in Maryland, despite sudden spikes in temperature from time to time. At home, one wishes to feel comfortable and warm during these cold seasons. It is a nuisance when your heater decides to give you the opposite: cold air. If your heater is blowing cold air, though, it may be due to one of these simple reasons.
The Heat Is Not On
Although it may seem silly, it is a possible mistake. Check to see what setting your thermostat is. If the heat is not on, you may have found your solution. Along with this, your fan should be set to “on” rather than “auto.” If your fan is “on,” it will run continuously even when the furnace is not producing heat. Cold air will blow during the intervals between the furnace’s runs.
The Air Ducts Are Leaking
Another way the hot air may elude your rooms is a leak in the air ducts. If your air ducts are leaking, your energy bills are likely higher than average, your home is excessively dusty, and your house has trouble reaching the desired temperature in warm or cold weather. An HVAC professional can remediate the issue.
Too Many Vents Are Closed
One strategy homeowners may use to conduct desired ventilation or temperatures is by closing off air vents. If you close off too many, your furnace may overheat, since the hot air has nowhere or too few places to go. With the pressure on the furnace, it may slow down and eventually overheat.
A Dirty Air Filter
A dirty filter can also cause the furnace to overheat and fail to produce warm air. An air filter captures the particles of dirt and debris and keeps them from circulating throughout your house. One should replace the filter at least once every two months. If the filter becomes too clogged with dirt, the air will fail to travel properly through the house and can shut off the system.
Fan Limit Switch Issue
The fan limit switch controls when the fan turns on and off. When heating your home, it will not turn on the fan until the burners have heated up the air. Ask a technician to adjust your HVAC settings or to replace the switch if needed.
