What you will be asked on the phone

The questions are short and none of them are stalling. What the system burns, what the thermostat is showing, whether anything is audible at the equipment, whether there is water or ice anywhere near it, and roughly how old the system is. Those five answers decide what goes on the truck, and on a rural call that is the difference between one visit and two.

Worth a look before you dial

• ✓Whether the thermostat display is lit, and whether fresh batteries wake it
• ✓The switch beside the furnace or on the joist above it, which looks like a light switch and gets knocked off
• ✓The breakers for the indoor blower and for the outdoor unit, which are usually separate
• ✓If you burn oil or propane, the gauge on the tank
• ✓On a high-efficiency furnace, the plastic pipes outside for snow, ice or a nest
• ✓The filter, if you cannot remember when it was last changed

The empty tank call

This one deserves its own heading. Running an oil tank dry does not simply stop the burner. It draws sludge off the bottom of the tank into the line and filter, so the system needs bleeding, a filter change and often a nozzle before it will run at all. Propane behaves differently again: once a tank empties, a leak test is required before service is restored, and that is a gas supplier step rather than ours. Either way, the gauge is the first thing to look at.

Frozen condensate in a hard freeze

High-efficiency furnaces produce acidic condensate that has to drain away. Where the trap, the line or the outdoor termination passes through an unheated crawl space, a garage or an exterior wall, a hard freeze plugs it. The pressure switch then sees water backed up in the inducer and shuts the furnace down. It looks like total failure and arrives in the coldest weather, and it is one of the more straightforward things we deal with once the cause is identified.

A cold house is not only uncomfortable

If a house is going to be without heat for any length of time in a hard freeze, plumbing becomes the next problem. Pipes in exterior walls and unheated crawl spaces go first. Opening the cabinet doors under sinks on outside walls and leaving a thin trickle running from the furthest fixture buys time. Tell us if the house is unoccupied, or if anyone in it is elderly or unwell, because that changes how we sequence the night.

You hear the cost before we set out

What an after-hours diagnostic call costs is stated before anyone gets into a truck, not after the work is finished. Installation and replacement estimates stay free, and those are separate visits.
