Repair or replace

The truth either way

Repair when the furnace is under 15 years old, the repair is under half the cost of a new one, and there are no heat exchanger cracks. Replace when it is 18 or older, the heat exchanger is cracked, or the expensive repairs keep coming.

Frequently asked

Straight answers

Why does my furnace smell like burning when it first kicks on in the fall?

Usually dust burning off the heat exchanger after a summer of sitting idle. It should clear in 15 to 30 minutes. If it stays, or smells electrical or like sulfur, shut the furnace off and call 405-375-4822.

How much does a furnace repair service call cost in Logan County?

$210 flat: $99 dispatch plus $111 diagnostic. The diagnostic is not credited toward the repair, and I give you a written repair estimate before any work starts. Guthrie, Crescent, Coyle, Marshall and Mulhall are all on my regular route.

How quickly can you get to Guthrie?

Guthrie is 30 to 40 minutes from my Kingfisher shop. No-heat calls go first in cold weather, and I aim for same day when the schedule allows.

Can you work on a furnace that is over 20 years old?

Yes, with an honest assessment. If the repair costs too much for the life left, I will tell you and show you replacement options.

Do you smell gas?

Leave the house now, do not flip switches or use the phone inside, and call your gas utility or 911 from outside. Once the utility says it is safe, call 405-375-4822 and I will find the cause.

Furnace not working?

Tell me what it is doing

A smell that will not clear, a flame that will not stay lit, a blower blowing cold. Describe it and I will tell you straight what I think it is before I drive out.
