November is the month to find out whether the furnace still lights
A furnace that sat idle for eight months is the one that fails on the first cold morning. Cook's tunes them in the fall, across every market where they're used.
The quick answer
Yes, a furnace in this territory needs a yearly check, and the time to do it is October or November, before the first front. The visit takes about an hour, it’s the same price in every market, it includes a combustion and heat exchanger safety inspection that no homeowner can do, and it is the single most effective way to avoid the no-heat call on the coldest morning of the year. Call 866-266-5709 and ask for a fall furnace visit; Cook’s schedules them in all ten markets.
That’s the answer. The rest explains why it matters here, where furnaces are the exception.
Why a Florida furnace fails differently
Up north a furnace wears out. Down here it rots in place. From March to November the burner compartment is a cool, humid cavity that collects dust, spider webs and the occasional wasp nest in the flue. The ignitor, a brittle ceramic part, sits unused and sometimes cracks on the first call for heat. The flame sensor grows a film that keeps it from proving flame, so the furnace lights and shuts off, lights and shuts off. In manufactured homes around Lake City and Live Oak, where electric furnaces are common, the sequencers that stage the strips stick from disuse.
The common thread is idleness, which is why the fall visit matters more for a furnace that runs three weeks a year than for one that runs four months.
What the visit covers
The gas furnace list, in the order Cook’s techs run it:
- Heat exchanger, inspected visually and with a mirror or camera for cracks, rust-through and separation. This is a safety item and it comes first.
- Burners, cleaned, with flame pattern observed: color, lift, rollout.
- Ignitor resistance measured; flame sensor cleaned and tested.
- Inducer and pressure switch checked; the flue inspected for blockage and proper draft.
- Gas pressure at the manifold set to spec; a leak check on the valve and unions.
- Combustion analysis in the flue, confirming clean burning and proper venting.
- Blower, filter and limit switch, because a furnace starved of air overheats and short-cycles.
- Thermostat, calibrated and confirmed to stage correctly.
- CO detector check in the home.
Electric furnaces get the strips, sequencers, limits and blower tested under load, and connections tightened, since loose lugs carrying strip current are a known fire risk.
What moves the price
A standalone furnace tune-up is a flat visit charge, the same from Jacksonville to Live Oak. It changes when the furnace shares the visit with an air conditioner check (a combined visit is priced as one), when the furnace is a rooftop package unit on a business (roof access, more units), and when parts are needed, which are quoted separately before they’re installed. Ask for the exact visit price and agreement tiers when you book. [[CONFIRM WITH JERRY]]
Residential and commercial
For homes, the fall visit is usually the heating half of a twice-a-year agreement. For businesses, gas heat lives in rooftop package units, and Cook’s folds the combustion check into the fall maintenance round on those units, scheduled when the building is closed and logged per unit. A property manager with gas heat on several buildings in Jacksonville gets one visit calendar and one set of records.
Scheduling and 24/7
Fall slots fill fast because every furnace owner in the territory remembers at the same time. Cook’s opens furnace scheduling in October, prioritizes agreement members, and keeps running tune-ups through December. The dispatch line is answered around the clock, and if a tune-up finds something that can’t wait, the repair can usually happen in the same visit from van stock. There’s no after-hours charge for anything, including the no-heat call this visit is meant to prevent.
Standards and warranty
Combustion work calls for training in gas safety and combustion analysis; ask which certifications the technician holds. [[CONFIRM WITH JERRY: certifications]] Every reading, from manifold pressure to flue CO, goes on the sheet. Parts replaced during a visit carry their manufacturer’s warranty and Cook’s labor warranty; ask for the term in writing. [[CONFIRM WITH JERRY]]

Furnaces are thickest in the gas-served and rural markets. See Lake City, Live Oak or Orange Park for the local picture.
Fall furnace questions
Does a furnace that's only used a few weeks a year still need an annual check?
More than one that runs all winter, in a way. Idle equipment collects dust, insects and moisture; seals dry out; ignitors crack from disuse as readily as from use. The annual check is short and it’s also what keeps the parts warranty valid.
What's the one thing you'll never skip on a gas furnace visit?
The heat exchanger inspection. Everything else on the list is about reliability; that one is about carbon monoxide. If the exchanger fails inspection the furnace is shut down and tagged, whatever else was planned.
Can the furnace check be combined with my air conditioner tune-up?
Yes, and for most homes that’s the efficient arrangement: a fall visit that covers both the heating side and a post-summer look at the cooling side. Agreement customers get it scheduled automatically.
Will you test my carbon monoxide detector?
The tech will check that you have one near the furnace and sleeping areas and that it responds to its test button. Cook’s can supply and install detectors if the house has none; pricing is quoted on the visit.
Is maintenance different for a propane furnace?
The combustion check is the same. Propane adds a regulator and tank-side supply pressure to the list, and a look at the orifices, which are sized differently from natural gas.
