It can be quite strange to find your furnace cooling your Asheville, NC, home instead of heating it. Nevertheless, under certain circumstances, your heating system may do exactly this. Here are a few reasons your furnace may start blowing out cold air:
Dirty Filters
If air cannot flow smoothly through your furnace, a whole host of system malfunctions may follow. Dirty air filters are among the most common impediments to proper airflow. So much debris may gather on your filters that it will prevent your furnace from expelling hot air, which may cause it to overheat, shut down and begin cooling instead.
To prevent this from happening, you must make sure that the filters stay clean. The best way to do that is to either wash or replace them every 90 days. You should do so more often if you have pets.
Leaky Ducts
Even if your furnace can produce and churn out warm air in acceptable quantities, that air must still be able to reach all parts of your home. Central heating systems typically use ducts to accomplish that task. However, age, corrosion, stray animals, biological growths and a variety of other factors may create holes in your ducts, and flowing air may escape through those holes.
This is why you must allow HVAC service technicians to clean and inspect your ducts. They can usually perform inspections as part of annual HVAC maintenance. We recommend scheduling duct cleanings at least once every three to five years.
Clogged Drain Line
The condensate drain line is a narrow tube that runs from your furnace’s heat exchanger to its drain pan. Its purpose is to remove the condensate that the system creates as it burns gas and generates hot air. If debris clogs the drain line, every aspect of your system’s performance may eventually suffer.
