Furnace repair and heating service in Troy, Ohio
We repair and replace furnaces and heat pumps in Troy, from the office at 2950 Stone Cir Dr. A replacement here needs a city zoning permit and a county building permit. We pull both. The no-heat line never closes.
Furnace repair, replacement, and heat pumps from techs who've worked every kind of Miami Valley home — with a 24/7 line for the January no-heat call.

What heating work do you handle?
Any brand, any age, diagnosed and quoted before we start.
Why does a Troy replacement need two permits?
Because the City of Troy contracts building permits out to Miami County. The zoning permit comes from the City of Troy Planning Department at 100 S. Market Street and confirms the work complies with city zoning. The building permit, covering construction, plumbing, electrical and mechanical, comes from the Miami County Building Department. Nothing else in the service area splits it this way, and a contractor who has only worked Montgomery County will file in the wrong place.
Where should carbon monoxide alarms actually go?
One on every floor, and one within about fifteen feet of each sleeping area, because the whole point is waking someone up. They do not need to be at floor level; carbon monoxide mixes with air rather than sinking. Keep them a few feet clear of the furnace itself so brief startup readings do not nuisance-trip them. Replace the units on the date printed on the back, because the sensor has a service life whether or not it has ever sounded. If one goes off and then stops, treat it as real and get the furnace checked.
How do I know if the heat exchanger is cracked?
You mostly do not, which is why it gets checked rather than guessed at. A cracked heat exchanger can put combustion gas into the air you breathe while the furnace still appears to run normally. The signs worth calling about are a burner flame that flickers or turns yellow when the blower kicks on, soot around the burner compartment, and a carbon monoxide alarm that trips even once. A furnace with a confirmed crack gets shut off and red-tagged the same visit. That is not an upsell, it is the only legal answer, and any company that offers to keep running it is telling you something about how they work.
The vents smell like burning dust when the heat first comes on.
That one is usually nothing. Dust settles on the heat exchanger over a summer of not running, and the first few cycles in autumn burn it off. It should fade within an hour or two of running and not come back. What is not normal is a smell that persists past that, a sharp electrical or plastic smell at any point, or anything like rotten eggs. The last one is the additive put into natural gas so you can smell a leak, and it means leave the house and call the gas utility before you call anyone else.
One room never gets warm. Is the furnace the problem?
Usually not. A furnace that satisfies the thermostat is doing what it was asked, and the room that stays cold is almost always a duct problem: a run that is too long or too small, a damper closed years ago and forgotten, a crushed flex duct in a joist bay, or a return that cannot pull enough air back for the supply to push. Adding return capacity fixes more of these houses than replacing the furnace does, and it costs a fraction of what a new system does. Ask for the airflow to be measured before anyone quotes you equipment.
