1. Why is my Furnace is Leaking Water?

Finding water around your furnace can be perplexing. Often, this is a sign of a condensation line leak, especially in high-efficiency furnaces designed to drain condensation away. A clogged condensation line or floor drain often leads to leaks.

If your system is a high-efficiency model, and the drain line appears to be ok, but you’re still noticing water; the issue could lie with a faulty secondary heat exchanger, humidifier, or internal drain system. These problems require professional attention from AirPro to prevent further damage to your furnace.

2. Furnace Frequently Turning Off: Understanding Short Cycling

A furnace that constantly turns off and on, known as short cycling, can be frustrating. A dirty air filter is a common culprit, stopping airflow and causing the furnace to overheat. Replacing the air filter might be a simple fix. If the problem persists, thermostat placement, the batteries, or an improperly sized furnace for your home could be to blame. Both of which might require a professional evaluation.

3. How do I Relight my Pilot Light?

If your furnace’s pilot light has gone out, follow these steps to relight it safely. Note that most modern furnaces no longer have a pilot light, they have an ignitor and a flame sensor. These item’s should be replaced by a professional.

  • Consult your furnace’s manual for specific instructions, turn the pilot dial to “off” for safety, and then to “pilot” to begin the relighting process.
  • Holding down the “reset” button while applying a flame to the pilot light opening can reignite it.
  • If you encounter difficulties, AirPro technicians are ready to assist.

4. Why is my Furnace Blowing Cold Air?

A furnace that blows cold air instead of heat can be alarming. First, check if the fan setting is on “auto,” ensuring the blower operates only when heating. A dirty air filter or an extinguished pilot light can also lead to cold air output. Addressing these issues can restore warm air flow throughout your home.

5. Furnace Running Non-Stop? Check the fan.

A furnace that doesn’t cycle off as expected might have its thermostat fan setting on “on.” Switching this setting to “auto” and adjusting the thermostat to a lower temperature than the current room temperature should initiate proper cycling. If the issue persists, the fan limit switch settings or a thermostat wiring issue could be at fault, necessitating a call to AirPro for expert assistance.

6. What if my Furnace is Making Weird Sounds?

Loud or unusual sounds from your furnace, such as rattling or screeching, often indicate mechanical issues, like a problem with the blower assembly or ductwork. Loose components, leaks, or wear and tear on belts and bearings can also contribute to noise. AirPro’s team can diagnose and resolve these issues, ensuring quiet and efficient furnace operation.

7. Why is my Furnace Making An Odd or Bad Smell?

Odors coming from your furnace, like a Dirty Sock Smell, called “Dirty Sock Syndrome” to more concerning things like the smell of natural gas, should not be ignored. A thorough inspection can determine whether the smell is due to a lack of use, a clogged air filter, a gas leak, or overheating components. In the case of a gas leak, immediate action is required for safety.
