Frequently Asked Questions

What Are the Most Common Signs That My Furnace Needs Immediate Repair?

One of the most urgent indicators of a furnace problem is a flickering or yellow pilot light instead of a steady, crisp blue. You should also listen for unusual mechanical sounds such as banging, screeching, or persistent clicking that suggest loose components or ignition failures. If you notice a sudden, dramatic increase in your monthly energy bills without a change in usage, your system is likely struggling with a major internal inefficiency. Finally, any persistent smell of burning plastic or rotten eggs requires you to shut down the unit immediately and seek professional assistance to avoid fire or gas hazards.

Why Is My Furnace Leaking Water or Showing Signs of Moisture Buildup?

If you have a high-efficiency furnace, water pooling around the base is often caused by a clogged condensate drain line or a malfunctioning collector box. Conventional furnaces may also appear to leak if a built-in humidifier has a cracked water line or if the evaporator coil from a shared AC system is frozen and thawing. In some cases, an improperly sized flue pipe can cause exhaust gases to cool and condense into liquid before they can exit your home. Because this moisture is often acidic and can corrode your heat exchanger, it is important to have a technician promptly identify and clear the blockage.

How Does a Dirty Furnace Impact My Home's Indoor Air Quality During Winter?

A dirty furnace serves as a collection point for dust, pet dander, and mold spores, which are redistributed throughout your living spaces whenever the blower turns on. When filters and internal components are coated in debris, the system loses its ability to trap airborne pollutants, leading to a noticeable increase in household dust and respiratory irritants. This stagnant air can exacerbate allergy and asthma symptoms, making your home feel stuffy and uncomfortable during the months when windows remain sealed. Regular cleaning of the blower motor and heat exchanger ensures that the air you breathe is filtered effectively and remains free of biological contaminants.

What Should I Do If My Furnace Is Short-Cycling or Turning Off Too Quickly?

If your furnace starts and stops in rapid bursts, your first step should be to check and replace your air filter to ensure proper airflow. Restricted air can cause the heat exchanger to overheat, triggering a safety limit switch that forces the system to shut down prematurely. You should also verify that all supply and return vents are open and unobstructed by furniture or rugs to maintain the necessary system pressure. If the issue persists after these basic checks, it likely points to a dirty flame sensor or a faulty thermostat that requires professional calibration or replacement.
