Why do it before the first freeze
Sources: National Weather Service normals; CDC.
Dallas/Fort Worth averages 8.1 nights at or below 32 degrees in December, 10.6 in January and 6.2 in February. A furnace that sat idle since March should be proven before it has to run all night.
The CDC advises having heating systems and other fuel-burning appliances serviced every year by a qualified technician and putting battery-powered or battery-backup carbon monoxide detectors near every sleeping area.
What a heating check usually covers
Burners and ignition
Burner flames, igniter and flame sensor are cleaned and tested.
Heat exchanger
Visual inspection for cracks, rust or soot, since a damaged exchanger can let exhaust into the house.
Venting
Flue and vent pipe condition, draft and any signs of back-drafting.
Blower and filter
Blower wheel and motor, filter condition and airflow through the ducts.
Controls and safety switches
Limit switch, pressure switch and thermostat operation.
Gas connections
Visible connections and the shutoff valve are checked for leaks.
A short list for homeowners
Things worth doing yourself before the first cold week.
- Replace the filter and mark the date on the frame.
- Open every supply vent and move furniture off the returns.
- Test the carbon monoxide alarms and check the date on them. The CDC says to replace a unit after 5 years or as the maker directs.
- Run the furnace for a few minutes on a mild day and note any smell or noise.
Cleaning questions
Does furnace cleaning mean duct cleaning?
Not necessarily. A furnace check concentrates on the burners, heat exchanger, venting and blower. Duct cleaning is a different job, so ask what is included.
How long does a furnace check take?
It depends on the equipment and what is found. The contractor can give you an idea when you book.
What if a crack is found in the heat exchanger?
The contractor should show you and explain the options. A cracked exchanger is a safety issue, and a furnace with one may be shut off until it is fixed.
