Common Furnace Issues We Fix Every Day
If your heating system is showing any of these warning signs, call us immediately. Our certified technicians arrive ready to restore your heat.
Furnace Blowing Cold Air
Blower fan runs constantly but blows cool or lukewarm air instead of warm, comfortable heat.
Furnace Turning On & Off Quickly (Short Cycling)
The heating system kicks on for 1-2 minutes, then abruptly shuts down before reaching the set temperature.
Squealing, Banging, or Rattling Sounds
Loud bangs during ignition or screeching motor bearing noises when the furnace cycles on.
Yellow or Flickering Burner Flame
A healthy flame should be steady blue. A yellow or flickering flame indicates incomplete combustion and carbon monoxide risks.
Water Leaking Around the Furnace Base
Condensation puddling around high-efficiency condensing furnaces or clogged humidifier drainage lines.
Uneven Heating & High Gas Bills
Certain rooms stay freezing while others overheat, accompanied by a sharp jump in monthly heating expenses.
