If your furnace is blowing cold air instead of warm air, don’t panic. The solution could be a simple one. Learn why your furnace might be blowing cold air and what you should do to combat it.
Remember that a cold furnace usually means there is a problem but it’s not necessarily a “BIG” issue. You can perform your own inspection before calling an HVAC technician just in case it’s something you can take care of yourself. Check the following areas for the source of the problem.
Not only does leaky ductwork allow your furnace’s warm air out, but it also allows the cold air from the outside in. Even small leaks can affect your home’s temperature, as well as reduce the overall efficiency of your furnace. You might need a professional’s help to locate leaks or holes in your ducts.
Dirty or clogged filters prevent your furnace’s warm air from circulating. To ensure maximum functionality, change your air filter every month or two. Additionally, invest in high-quality filters to ensure good indoor air quality.
Sometimes, the problem really is as simple as a broken thermostat. Make sure the thermostat is switched to “on” and that the batteries are in working order. If the thermostat is electric, it may have lost connection.
To turn your pilot light back on, hold down the gas valve regulator and reignite it with a lighter. No pilot light means no warm air. Always double check!
Your gas valve is controlled by the thermocouple. If either goes out, you will have difficulty keeping your pilot light on.
A faulty electrical ignition prevents your furnace from getting hot. This is not something you can fix on your own, so if you suspect this is the problem, call an HVAC technician.
Over time, your flame sensor can accumulate a layer of dirt, dust, or grime. This causes the burner to turn off prematurely.
Not every furnace problem is avoidable. However, you can take preventive measures against the above-mentioned problems by employing proper HVAC maintenance tips.
Pay attention to your air filter’s packaging, and change it according to the manufacturer’s recommendation.
Every month or so, lay eyes on your furnace and look for any obvious problems. Cracks, rust, dirt, etc. indicate potential problems.
Professional tune-ups prevent small issues from becoming big issues. Nipping problems in the bud always saves money.
