We do, and it is deliberate. Nozzles, oil filters, cad cells, electrodes and pump parts ride on our trucks through the heating season and we set combustion with an analyzer rather than by eye. A lot of shops have quietly exited oil work, which is exactly why we have not — in Big Spring farm country it is the primary heat.

A delivery stirs sediment that has settled in the tank, and it reaches the filter and nozzle. We see this pattern regularly out here. The fix is the tank filter, the strainer, a correctly sized nozzle and a proper combustion setup — and a tank producing that much sediment is telling you something worth inspecting.

It depends entirely on the arrangement, and it is worth having looked at. We have found properties in this area where a tightened-up house plus a drawing wood stove and a running dryer caused the oil appliance to backdraft. A worst-case depressurization test with exhaust appliances running is how you find that, not an appliance-by-appliance check on a calm day.

Usually duct insulation that fell off in the crawlspace years ago, so you are heating the crawlspace and delivering whatever is left to the rooms. It is the most consistent finding we make on rural comfort calls and among the cheapest to correct. We inspect and photograph the runs before quoting anything.

It depends entirely on the flue, the appliances and the air available, which is why it needs testing rather than a general answer. The two produce very different flue gas volumes and temperatures, they are not coordinated, and in a basement that has been tightened over the years they may be competing for combustion air. We test draft and spillage with both operating, under the conditions that actually occur, and give you the readings. Where the arrangement is not safe we say what would make it safe rather than simply condemning it.

Usually because the air never gets there. Long duct runs through an unconditioned crawlspace lose heat through the duct wall and lose air through unsealed joints, so the room at the end of the longest run receives the least of what the furnace produced. Wind exposure across open ground makes the same room harder to hold. Sealing and insulating those runs and correcting the supply to that specific room is inexpensive and usually fixes it without touching the furnace.
