Crest Electrical / Mechanical Solutions
Signs your furnace needs repair
Is your furnace trying
to tell you something?
Call us if you notice any of these. Safety first: if you smell gas (rotten eggs) or your carbon monoxide alarm goes off, leave the house now and call 911 or your gas company from outside.
Won’t turn on
Nothing happens when you raise the thermostat. Check the breaker and the thermostat batteries, then call us.
Short cycling
Turning on and off every few minutes wears the system out and leaves rooms cold.
Strange noises
Banging, squealing or rattling when the heat starts isn’t normal.
Unusual smells
A dusty smell on the first cold day is normal and fades. A lingering burning or electrical smell isn’t.
Uneven heat or high bills
Cold rooms, or a gas bill that jumped, can mean the furnace is struggling.
