Pressure switch replacement only when the switch failed

The furnace won't start, or it shuts down on a safety. The pressure switch is a suspect. Pressure switch replacement fixes it only if the switch is actually what failed.

The switch proves the furnace is venting before it's allowed to fire. A blocked vent or a weak inducer can trip it too.

Switch, venting, or inducer?

We test all three. The switch gets replaced only when the switch itself has failed, and then we watch the furnace finish a complete heating cycle before we pack up.

Good to know

Questions people ask before they call

That depends on what failed and on the equipment. We tell you the number after we look at the unit, and if replacing it is on the table, you get both numbers.

No. Everyone here is paid hourly, not on commission. When a repair will hold, that's the recommendation.

Yes. We answer 24/7. Sundays and holidays are billed at double time.
