House cold right now? The heating line is (208) 782-8267. To match a symptom to a likely cause before you dial, the furnace symptom guide covers the no-start, cold-air and short-cycle complaints.
Is Star inside your everyday service area, or a special trip?
Everyday. Highway 44 runs from Caldwell through Middleton and straight into Star, so the technician is not crossing the valley to reach you. Our scheduling records for Star addresses begin in April 2021 and show 186 completed jobs of every kind at 88 Star addresses for 89 customers, all in ZIP 83669, the latest completed in July 2026. The company is far older than the software keeping that count: American Rooter & Drain was established in Caldwell, Idaho in 1945, and the records start when the current dispatch system did.
Heating and cooling is the smaller share of that history, reported here as it is rather than rounded up. Star addresses account for six completed furnace and air-conditioner repair, service, no-heat and not-cooling calls at four addresses for four customers, June 2023 through January 2026; five completed furnace and air-conditioner tune-ups at four addresses; three completed HVAC installs at two addresses; and ten completed estimate, inspection and other heating-and-cooling visits at seven addresses. Twenty-four completed heating and cooling jobs altogether. A short record, so the larger patterns below come from the whole service area, and the page says which is which every time.
Neighbours: Eagle, Middleton, Meridian, Caldwell. The rest of what we do in town: the Star service page.
My furnace is out right now. How fast can you be in Star?
Start with the Star record. Of the 24 completed heating and cooling jobs at Star addresses, ten carry both a booking timestamp and a completion timestamp: nine were completed on the same calendar day they were booked, none exactly one calendar day later, and one falls into neither count. Booked_at is not always a scheduling timestamp in this data — on some jobs it reflects when an earlier estimate was sold rather than when the visit was set up — so we won't guess what happened on that tenth job. A completed-work record on a small sample, not a promise about tomorrow.
Across our whole service area the repair-type record is 1,154 completed furnace and air-conditioner repair, service, no-heat and not-cooling calls for 772 customers at 755 addresses, March 2023 through September 2026.
A cold house is scheduled ahead of maintenance and estimate visits. What pushes a same-day answer to next morning is weather: the first hard freeze and the coldest week of January drop every tired furnace between Caldwell and Boise inside the same few days. Call early rather than waiting to see whether it sorts itself out, and say if anyone in the house is elderly, an infant, or fragile in the cold.
My house is on a well and septic. Does that matter for a furnace call?
Enough that it is the first thing we ask in Star. The Star Sewer and Water District has supplied central water and sewer since 1966 across a box bounded roughly by the Ada–Canyon county line and Kingsbury Road on the west, Highway 16 on the east, the Boise River on the south and the foothills on the north. But the town did not incorporate until December 1997, so much of what surrounds the old downtown was developed as county ground, and inside the district's box there are still homes on a private well, a septic tank, or both.
Three things change on a well-and-septic furnace call:
- The humidifier. A furnace-mounted humidifier on hard well water scales up quickly. A lime-choked pad stops adding moisture long before anyone notices, and a solenoid that sticks open drips water down the cabinet onto the control board. A wet board is a furnace fault with a plumbing cause, so the humidifier gets checked on every well-water call.
- The condensate. A high-efficiency furnace makes mildly acidic water while it runs. Draining it toward a septic tank is common and the volume is small, but the line has to run somewhere that does not freeze, and a condensate pump in a garage or crawl space is the piece that quits on the first cold night.
- The power. When the power drops on the acreage, the furnace and the well pump go out together. Trickling a faucet to protect pipes stops working with no pump, and the pump house becomes the one small heated space you cannot let freeze. Say "well" and "pump house" when you call.
Septic pumping in Star is a flat $395 up to 1,000 gallons, booked on the same dispatch line.
What gets tested once the furnace door is off, and in what order?
A gas furnace starts up in a strict order, and when it will not heat it has stalled at one particular link in that chain: thermostat call, board self-check, inducer fan proving a draft to the pressure switch, igniter, gas valve, burners, flame sensor confirming fire, then the main blower, with a high-limit switch watching cabinet temperature throughout. Wherever the chain breaks is where the fault lives, and the board on a modern furnace remembers it as a blink code behind the sight glass. That code survives until somebody cuts the power, so leave the breaker alone until the technician has read it.
The quick checks come first: breaker, the furnace's own on-off switch, the blower door on its safety plunger, the filter, the thermostat, and on a condensing furnace the two white pipes outside and the condensate trap, because a plugged trap or an iced intake stops a furnace as surely as a dead part.
Then meters, not opinions. Flame-sensor current, because an oxidised rod reads a weak flame and the board shuts gas to a burner that is perfectly lit. Capacitor strength against its label. Blower and inducer amps against the nameplate. Manifold gas pressure. Temperature rise across the heat exchanger against the range stamped on the door, the quickest way to separate a furnace starved for air from one with an ignition fault. Carbon monoxide at the registers. And the heat exchanger itself, because a cracked exchanger takes the furnace out of service rather than into repair. Finally, why it failed: an igniter killed by a starved filter will die again before spring if only the igniter changes.
Do you carry furnace parts, or does everything get ordered?
What rides along is the short list that actually fails in the cold: hot surface igniters, flame sensors, universal pressure and high-limit switches, universal control boards, induced-draft motors for 80-percent and 90-percent furnaces, universal blower motors and their run capacitors, condensate traps and pumps, plain thermostats, and the cartridge fuses that guard an electric furnace. What gets ordered is anything made for one manufacturer's cabinet and no other: a factory gas valve, a two-stage inducer assembly, a variable-speed blower module, a board for a discontinued model. You hear which group you are in before the technician leaves, with a plan for keeping the house warm if it is the second.
Why does a Star furnace pick January to quit?
Because January is when the schedule is already full. Of the 24 heating and cooling jobs we have completed at Star addresses, six were completed in January, more than in any other month, and February and March together produced none. A small calendar, but the furnace that limped through October gives up on the coldest week.
Star adds a local aggravation. The town sits between the Boise River and the foothills, and on the still mornings of a winter inversion the freezing fog settles along the river bottom and rimes onto the plastic intake of a high-efficiency furnace. The intake ices, the inducer cannot pull the draft the pressure switch is waiting for, and the board locks the furnace out with a code blaming a switch that is not broken. If you know where your two white pipes exit the wall, look at them after a foggy night, clear them, reset once, and if it locks out again stop resetting and call.
The other local pattern is dust: farm ground on one side of town, subdivisions still under construction on the other, and a one-inch filter that can be grey inside a month. A furnace pulling through a plugged filter overheats, shuts down on its high-limit, cools and relights, and every cycle costs the igniter a little of its life.
Does a post-2000 Star subdivision house break differently from the old downtown?
It does. The settlement dates to 1905, when travellers between Middleton and Boise used the star on the schoolhouse to find east and west; that schoolhouse still stands as the home of the Star Historical Society. The blocks around it near the Star Bridge hold the older homes: a furnace in a basement or on a platform under the floor, sometimes venting into a masonry chimney shared with a gas water heater, so a burner that catches, runs a few seconds and dies is usually a draft complaint rather than a gas one.
The great majority of Star is the other thing. The city has grown severalfold since 2000, and post-2000 builds dominate: the furnace is in the garage or a laundry-side closet, it vents through two white plastic pipes, it makes water as it runs and so carries a trap and a drain line, and the ducts are flex through an attic or a crawl space. The bonus room over the garage is the coldest room in the house every January, and that is nearly always a duct problem rather than a furnace one. A garage furnace's condensate line is what freezes on the first hard night and shuts it down on its overflow switch. On the acreage toward the foothills, add a well, a humidifier and sometimes a propane tank to that picture.
The house is cold and the sun is going down. What should I do until you arrive?
If you smell gas, if a carbon monoxide alarm is sounding, or if there is soot or scorching around the furnace cabinet, leave the house and call from outside.
If it is only cold: one reset is reasonable; five in a row are not, because every reset erases the fault code the technician needs and can leave unburned gas in the cabinet. A space heater plugs directly into the wall, one to a circuit, nothing near it, and off when you sleep. Do not heat the kitchen with the oven door open.
Then protect the plumbing, because we would rather not take the burst-pipe call from you in the morning. Open the cabinet doors under sinks on outside walls. Leave a pencil-lead trickle running at the tap farthest from where the water enters the house, unless you are on a well with the power out, in which case find the main shutoff instead. Close the garage door if the furnace lives out there, and disconnect any hose bib still attached, because that is the leak you find in April when Star's pressurised irrigation charges.
What decides the price, and why won't you put a number here?
Because a figure for a furnace nobody has opened is a number invented to fill a page. The real price is built from a handful of things:
- What failed, and whether it is a stocked universal part or an assembly on order.
- Gas or electric equipment, which are two different parts lists, with propane a variation on gas.
- Where the furnace sits. A garage unit with clear floor and an attic unit reached by ladder in January are different hours of work.
- Whether the dead part was the cause or the casualty. A pressure switch tripped by an iced intake, replaced without clearing the intake, is a repair you pay for twice.
- What the safety checks find. A cracked heat exchanger ends the repair conversation and starts a replacement one, however old the unit is.
- Water. On a well-and-septic house, a scaled humidifier or a frozen condensate run can be the whole job or an extra line on it.
What you get instead is one fixed price, in writing, before anything is unscrewed, and the right to say no to it. For scale: on the 24 completed heating and cooling jobs at Star addresses, 37 estimates were written and 13 were sold; the other 24 were written up and not bought.
When replacement is the honest answer, the technician writes both paths down, repair and replace, with a number on each, and you keep the paper; that comparison is free. The Star record is too short to show a pattern on replacements, so we will not invent one. The repair-or-replace guide walks the arithmetic through, and HVAC installation in Star covers sizing and install day.
Will anyone from the city need to inspect a furnace repair in Star?
Not for a repair. A like-for-like igniter, flame sensor, motor, board or gas valve is service work, and no permit is pulled. Replacing the furnace is permitted work with a final inspection, and so is new gas piping or a change to the venting. When that is the job, the permit is pulled under our heating license and our office schedules the inspection with whichever building office has jurisdiction for your address. In Star that depends on which side of the Ada–Canyon county line the parcel sits on and whether it is inside city limits, and you do not need to work any of that out yourself.
Propane, an electric furnace or a heat pump: does the repair change?
Tell the dispatcher which, because it changes what gets loaded.
Propane. Inside the district's box the mains carry natural gas; on the acreage north toward the foothills you may be on a tank. It is the same furnace with a different fuel train: smaller burner orifices, a higher manifold pressure, usually a conversion kit on a natural-gas unit. A tank that ran low and was refilled has air in the line to purge before the furnace lights reliably.
Electric. Nothing burns, so the flue, the flame sensor and the gas valve drop out of the picture. What is left is a bank of resistance elements staged on by sequencers, a contactor and the disconnect fuses; the diagnosis is amp draw per element.
Heat pump with furnace backup. The no-heat call begins at the outdoor unit, and the furnace may be blameless. Start at heat pump services in Star, or AC repair in Star if it is the cooling side misbehaving.
You are a plumbing company. Can one visit cover the furnace and the plumbing?
Yes, and in Star that is where our history is: 24 of the 186 completed jobs at Star addresses are heating and cooling, and the rest is plumbing, drain, septic and other work. Four of the 13 Star customers with completed heating and cooling work have also had us out for a different kind of job at a Star address.
It matters on a furnace call because a house does not file its problems by trade. A bedroom that never warms up can be a duct that dropped off its boot in the crawl space, with the furnace blameless. One dispatcher, one truck. The water heater in Star, $59 drain clean, gas line and duct cleaning pages cover the rest.
Would a September tune-up have kept my furnace running?
Sometimes, and it would at least have moved the failure to a warm weekday. Across our service area we have completed 930 furnace, air-conditioner and combined tune-ups for 544 customers. At Star addresses the number is five, at four homes. A tune-up is not a guarantee against January; it is a way of choosing when the weak part gets found, on a September morning instead of a January evening when the whole valley is calling. Book it before the first frost. HVAC maintenance in Star sets out what the visit covers, and the general furnace tune-up page has the checklist.
Who shows up at a Star address, and under whose license?
The heating and cooling side of American Rooter & Drain trades as American Heating & Air. The parent company was established in Caldwell, Idaho in 1945 and has served the greater Treasure Valley since 1945. The mechanical work on this page is done under Idaho HVAC Contractor License 029771, from 1005 Commercial Way, Caldwell, ID 83605.
Heat off? Call (208) 782-8267 and give the dispatcher four things: what the furnace is doing (silent, clicking without lighting, lighting and dropping out, or running without warming the house); natural gas, propane or electric; whether the house is on a well or a septic tank; and where the furnace lives, whether garage, closet, crawl space or attic. Those four answers decide what goes on the truck before it leaves Caldwell.
