Sapulpa asks a lot of a furnace from October to April

Seven months of the year, your furnace is the thing standing between your house and a 29°F night. That means the burner is lighting and shutting off many times a day, all winter long. Each cycle puts a little more wear on the igniter and the flame sensor, and eventually one of them quits doing its job. That usually shows up as a furnace that tries to start and can't, or one that lights and then shuts itself back off.

The last ten years brought 9 winter storms and 65 damaging wind events through this area, and storms here knock out power. A furnace that was running fine can come back confused after the power drops and returns, or not come back at all, right when you need it most.

A new furnace would cut about $110 a year off heating for a typical Creek County home.

  • A new high-efficiency furnace$490 a year
  • An older furnace$600 a year

Estimates for a typical Creek County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Oklahoma fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when one part has failed and the heat exchanger is sound.

Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.

Oklahoma requires HVAC contractors to hold a state license.

That license comes from the Construction Industries Board, and it covers the contractor rather than the specific job. The board tests contractors before they can hold one and keeps a record of who does. So the license tells you the person is the one the state checked, not that this particular furnace repair was inspected on its own.

For a furnace repair, that license is what stands behind the work. Gas connections are the part that matters most, since a poor seal or bad joint is what makes a furnace dangerous rather than just broken, and the licensed contractor is who is accountable for getting that right. In Creek County, close to half of homes heat with gas, so this is the rule that is actually doing the work when a furnace like that needs fixing.

Why won't my furnace turn on?
Start with the thermostat and the power to the furnace. Check that the thermostat is set to heat and the temperature is above room temperature, and check the breaker and the furnace's own power switch, which looks like a light switch near the unit. If those are fine, the igniter or a safety switch may be keeping it from starting, and that calls for a contractor to test. With winter nights here averaging 29°F, a furnace that won't start is worth getting looked at the same day.
Why is my furnace blowing cold air?
Most often the blower is running before the burners have caught up, which is normal for a short stretch after startup. If cold air keeps coming for more than a few minutes, the igniter may be failing to light the burners, or the flame sensor may be shutting the burners off right after they light. A dirty filter can also cause this by starving the burners of airflow. A contractor can tell which one it is once they see the unit running.
Why won't my furnace pilot light stay lit?
A pilot that won't stay lit usually means the thermocouple has worn out and stopped sensing the flame correctly. It can also mean a draft in the area of the pilot, or a buildup of dirt at the pilot tube. Furnaces with a standing pilot don't use electricity to keep that flame burning, so a power outage won't affect it, but a bad thermocouple will. This is a repair, not something to keep relighting on your own.
