Oil-to-Gas Flue Conversion in Trumbull, CT
Connecticut runs more oil heat than any state in the country, so it does more conversions than most. The part that gets left out of the quote is what happens to the chimney.

Leave the building and call from outside — that is an emergency services call, not a service call. A blocked or failed flue is one of the ways carbon monoxide reaches a living space, and headaches that clear when you leave the house point the same way. If you have had a chimney fire — a roaring sound, dense smoke, or debris on the roof — do not light another fire until the flue has been inspected.

Oil-to-Gas Flue Conversion in Trumbull
Much of Trumbull's housing was built before central cooling was normal and often before ductwork was, so heating and cooling arrived separately and at different times. That is why so many houses here run a boiler for heat and something entirely different for cooling.
About 62% of homes in Trumbull predate 1970, so the original heating system has usually been replaced at least once and cooling added afterward; 42% of them still heat with oil, and oil condensate is acidic enough that those flues deteriorate from the inside where nobody looks. (US Census ACS 2022)
Why the chimney is part of the job
An oil boiler produces a lot of hot flue gas. A modern gas boiler produces far less of it and produces it cooler. The chimney does not change, so after a conversion the appliance is venting into a flue several times larger than it needs.
The consequences are immediate and they compound. The gases cool on the way up, they condense, the condensate is acidic and it soaks into mortar joints and flue tile. The flue also does not draw the way the appliance expects, which is a combustion issue rather than just a masonry one.
None of this is exotic and all of it is avoidable. A correctly sized stainless liner is part of doing the conversion properly, and it should appear on the quote next to the boiler rather than as a surprise afterwards.
Getting the size right
Diameter comes from the appliance manufacturer's venting tables, based on the input rating and the height and configuration of the chimney. It does not come from what fits. Ask to see the table.
Insulation on cold chimneys
Exterior chimneys, chimneys on unheated walls and tall runs all shed heat from the liner. Where they do, insulation is what stops condensation happening even at the correct diameter. On an exterior stack in Connecticut this is usually required rather than optional.
The details that get skipped
Beyond the liner, a conversion leaves loose ends in the chimney, and they are the things that get missed when the focus is on the boiler.
The abandoned opening
Where the old oil appliance connected, there is a hole in the chimney. It needs properly sealing with masonry, not covering with a plate. An unsealed opening lets flue gases into the basement and lets air into the flue, which affects the draft.
Anything else venting into that chimney
A water heater frequently shares the flue. If the boiler leaves and the water heater stays, that water heater is now alone in a flue sized for two appliances, which is its own oversizing problem. It needs including in the sizing calculation, not discovering afterwards.
A camera survey either side
Before, to establish what condition the flue is in after decades of oil. After, to confirm the liner is properly seated and connected. Both are quick and both are worth insisting on.

Oil-to-Gas Flue Conversion in Trumbull — FAQs
Should the chimney be repaired or rebuilt?
It depends how far the damage goes. If a key scrapes mortar out but the brick is intact, that is repointing. Once brick faces have flaked through, a brick can be rocked by hand, or the stack leans, repointing has nothing sound to bond to and a rebuild is the honest answer. Most rebuilds stop at the roofline, because that is the section taking weather from every side.
Do you charge for a quote in Trumbull?
We charge nothing at any point — contractors pay us, you never do. What a company charges to attend or to carry out an inspection is theirs to set, so agree it with them before they come out. An inspection is a real piece of work with a written report attached, and it is reasonable for it to be chargeable.
How often should a chimney be inspected?
Annually, whatever it vents — that is the NFPA 211 standard and it covers gas and oil appliances as well as wood. Sweeping frequency is separate and depends on what and how much you burn. An appliance used twice a year still needs the annual look, and those are the ones where neglected faults turn up.
Do we need a chimney liner?
If a camera survey finds cracked tile, washed-out joints or a separated liner, yes. You also need one whenever the flue is the wrong size for the appliance now venting into it, which is the common case after any change of fuel or appliance. A liner is sized from the appliance manufacturer venting tables, not from what happens to fit down the chimney.
What does a Level 2 inspection include?
Everything in a Level 1 visual check, plus a camera survey of the entire flue and an examination of accessible attic, crawl space and basement areas. It is required on a property transfer, on any change of fuel or appliance, and after a chimney fire. A general home inspection does not include it.
Is chimney waterproofing worth doing?
On sound, porous, exposed masonry it genuinely slows the water absorption that destroys brick. On masonry that has already started to flake it is worse than doing nothing, because it traps water behind the damaged face. And it has to be a breathable repellent rather than a film-forming sealant — the film is what causes the damage people then blame on waterproofing.
Do we need a permit?
Typically yes, and requirements vary by municipality. Ask who is pulling it. A conversion involving gas piping and appliance venting is not work to do unpermitted.
Is the liner included in a standard conversion quote?
Frequently not, and that is the single most common cost surprise in a Connecticut conversion. Ask explicitly whether flue relining is in the price before you sign anything.
