Why Your Furnace Is Blowing Cold Air

A furnace that runs but delivers chilly air instead of warmth is one of the more frustrating heating problems a homeowner can face. Several different issues can cause it, and identifying the right one quickly matters for both your comfort and your system’s health.

South Shore Mechanical can diagnose and address underlying furnace issues like:

  • Incorrect thermostat settings. Your thermostat may be set to “ON” rather than “AUTO,” causing the blower to run continuously even when the furnace isn’t actively heating. A temperature setting that’s simply too low can produce the same effect.
  • Dirty air filters. A clogged filter restricts airflow until your furnace overheats and shuts off its burners as a safety measure, leaving only the blower running and pushing unheated air through your vents.
  • Pilot light or ignition failure. Gas furnaces with an extinguished pilot light or a malfunctioning electronic ignition can’t generate heat, so the blower keeps running while the burners stay off.
  • Flame sensor problems. A dirty or failing flame sensor may incorrectly signal that no flame is present, shutting down the burners while the fan continues to circulate air through your ductwork.
  • Fuel supply interruptions. Running out of oil, an accidentally closed gas valve, or a gas line issue prevents fuel from reaching the burners and leaves your system unable to produce heat.

Some of these problems are simple fixes; others need professional attention. Our technicians can diagnose the exact cause and get your furnace heating properly again.

Gas vs. Electric Furnaces: Which Is Right for Your Home?

Choosing between a gas and electric furnace comes down to your home’s infrastructure, your budget, and your long-term heating priorities. Gas furnaces typically cost less to operate in our region. Natural gas rates here, while above the national average, generally run lower on a per-BTU basis than electric resistance heating, and gas systems heat homes faster, which matters during a bitter cold snap. They do require access to a gas line and proper venting, but they deliver powerful, efficient warmth for larger homes.

Electric furnaces need no gas connection or venting, making installation simpler and often less expensive upfront. There’s no combustion involved, so they require less maintenance and may last longer. They’re a practical choice for smaller spaces or homes without existing gas service.

Not sure which type fits your home? Our team can assess your property, talk through your comfort preferences and budget, and help you decide. Free estimates are available for new furnace installations throughout the Quincy area.
