6 Signs Your Hartly Furnace Needs Repair
Furnace starts then shuts off after a few minutes
This is the number one furnace repair call in Hartly. A dirty flame sensor causes intermittent lockout. The sensor cannot detect the flame, so the control board shuts down the gas valve as a safety measure. Farm dust fouls these sensors faster in rural homes than in suburban Dover. Typically a quick same-day fix.
No heat at all. System blows cold air.
Most likely a failed hot surface ignitor. The ignitor glows to light the burner. When it cracks, no ignition. No heat. Ignitors in Hartly’s dusty environment degrade faster. Carrier, Trane, and Goodman furnaces all use them. Quick replacement, parts on the truck.
Yellow or orange burner flames instead of blue
Blue flames mean clean combustion. Yellow or orange flames mean incomplete combustion. Could be dirty burners, incorrect gas pressure, or a cracked heat exchanger. The last one is serious. Carbon monoxide risk. Propane furnaces along Halltown Road need correct orifice sizing. If the flame color is off, call immediately.
Metallic or rotten-egg smell when the furnace runs
Metallic smell can indicate a cracked heat exchanger leaking combustion gases into your airstream. Rotten egg smell near a propane furnace means a possible gas leak. Both are emergencies. Leave the house. from outside.
Furnace making banging, popping, or screeching sounds
Banging at startup means delayed ignition. Gas builds up, then lights all at once. Common in older Carrier and Rheem furnaces with dirty burners. Screeching means a failing blower motor bearing. Popping may be ductwork expanding from heat. The first two need a tech. The third is usually cosmetic.
Carbon monoxide detector alarming
Evacuate immediately. Call 911 first. Then A cracked heat exchanger in a gas or propane furnace is the most common HVAC-related CO source. Many Hartly furnaces from the 1980s and 1990s are in the age range where heat exchanger failure becomes likely. We check heat exchanger integrity on every diagnostic.
