Before you book
Check that the thermostat is set to Heat and above room temperature, the furnace switch near the unit is on and the filter isn't clogged.
Common faults
Dirty flame sensors, failed igniters, blocked condensate lines on high-efficiency furnaces and tripped limit switches cause many no-heat calls.
Short cycling
A furnace that starts and stops every few minutes may be overheating from poor airflow or have a sensor problem.
Smells
A dusty smell on the first run of the season is normal. A strong gas smell is not: leave the house and contact the gas utility's emergency line from outside.
Carbon monoxide
Every home with gas appliances should have working CO alarms near sleeping areas. Test them each fall.
Fall tune-ups
A yearly inspection checks burners, the heat exchanger, venting and safety controls before heavy use.
Older furnaces
Furnaces well past their expected life, with rust or cracked parts, are worth pricing for replacement alongside the AC.
Get help
Tell the technician the furnace type and what it's doing. Send a request and an AC company will get in touch.
Filters
A clogged filter can overheat a furnace and trip its safety switch. Change it before the heating season.
Condensate on high-efficiency furnaces
High-efficiency furnaces make water and drain it through a small line. A clogged line can shut the furnace off; it's an easy fix for a technician.
Thermostat
A thermostat set to cool, a dead battery or a loose wire can look like a furnace failure. Check it first.
