Signs your furnace needs repair
Winter inversions in the river corridor push heating systems hard, and most furnace failures land on the coldest nights of the year. Call (208) 939-2566 when you notice:
- Cold air from the vents while your furnace runs
- An inducer fan that runs while the burners never light
- A click at startup, then silence
- Groaning, squealing or a cabinet that shakes when the blower starts
- Burners that keep shutting off before your home warms up
- A yellow burner flame instead of a blue one
How we diagnose and repair a furnace
We repair every major make and model of heating equipment, from a compact gas furnace in a manufactured home to a zoned system in a riverfront home, and we diagnose with digital manometers, multimeters and combustion analyzers.
Igniters and flame sensors
Hot surface igniters heat to over 2,000 degrees Fahrenheit in seconds, and over time they crack or burn out. If the inducer fan runs but the burners never light, or you hear a click followed by silence, the ignition system is the usual cause. Our technicians carry replacement igniters and control boards. We also clean and align the flame sensor, a small rod that collects oxidation and makes your furnace think the burners never lit.
Blower motors and capacitors
A failing blower motor groans, squeals, shakes the cabinet or will not start, and without airflow the heat exchanger overheats until the high-limit switch shuts your furnace down. We measure the motor's amperage draw against the manufacturer's rating, test the run capacitor that starts it, and can often replace a seized motor on the spot.
Limit switches and safety controls
The high-limit switch shuts off the burners when the air inside your furnace gets too hot, usually because of a clogged filter, closed vents or restricted ductwork. A switch that trips again and again wears out. We test every safety control for continuity and voltage, and when a limit switch is tripping we find the cause before we replace it, so the new switch lasts.
Heat exchangers and carbon monoxide
Years of heating and cooling can crack the seams of a heat exchanger, and a crack can let carbon monoxide into the air you breathe. We inspect the heat exchanger with a camera for cracks, rust and soot, and run a combustion analysis that measures CO in the flue gas and the supply air. If we find a cracked heat exchanger or a CO leak, we shut the furnace down and tag it so it is not run until it is repaired or replaced.
Repair or replace
A gas furnace in the Garden City climate typically lasts 15 to 20 years. If yours is near that age, needs an expensive repair to the blower or control board, or keeps pushing your gas bill up, we show you the repair-versus-replace math. When a repair costs half the price of a new system or more and the unit is out of warranty, replacement is usually the better choice. So is a furnace that needs a different repair every winter.
Efficiency is rated in AFUE, the share of the gas you buy that becomes heat in your home. Older furnaces in Garden City often run at 60 to 70 percent. New standard-efficiency furnaces start at 80 percent, and high-efficiency condensing furnaces reach up to 98 percent. Single-stage furnaces run on or off; two-stage furnaces run on low through most of the winter and switch to high in a cold snap; modulating furnaces adjust their output in steps as small as 1 percent and hold your temperature within a fraction of a degree. We help you calculate the long-term savings of a high-efficiency model.
How we install
We size every new furnace to your home's square footage, attic and wall insulation, window quality and the direction your home faces. An oversized furnace short cycles and leaves hot and cold spots; an undersized one runs all night and never reaches the set temperature.
Your new furnace goes in level and supported to cut vibration and noise. For a high-efficiency condensing furnace we run dedicated PVC intake and exhaust pipes and make sure the acidic condensate drains properly. We check the gas connection for leaks, install a sediment trap (drip leg) ahead of the gas valve, verify electrical polarity and grounding, and fit sheet metal transitions to your supply and return plenums sealed with mastic. We handle the permit and the final safety check.
Fall tune-ups
A precision tune-up every fall is how you avoid a no-heat night in January. We test for carbon monoxide, inspect the flue for corrosion and blockages such as bird nests, clean the burners and the flame sensor, measure the temperature rise against the manufacturer's range, check the gas pressure at the manifold, and check the blower capacitor and amp draw. If a part is drifting out of spec, you hear about it before it fails.
Heat pumps and dual fuel
A heat pump moves heat from the outdoor air into your home and keeps working below freezing. For many Garden City homes we pair one with a gas furnace as a dual-fuel system: the heat pump carries the milder days of fall and early winter, and the furnace takes over when the temperature drops into the teens.
Thermostats and air quality
We install, wire and program Google Nest and Ecobee smart thermostats, including a C-wire for constant power, and we fix blank screens, loose connections and thermostats that read the wrong temperature. For a home with a hot upstairs and a cold downstairs, we install zoning: motorized dampers in your ductwork, each zone on its own thermostat.
Heating your home through a Garden City winter dries out the air inside. Our whole-home humidifiers connect to your furnace and hold indoor humidity in the 35 to 45 percent range, and our air filtration systems catch the dust and pollen that stay indoors through a long winter.
Garden City questions
Who should I call for furnace repair or replacement in Garden City?
Air Care does. We are an Idaho-licensed HVAC contractor (HVC-C-1644) based in Eagle, and we repair, replace and maintain gas furnaces and heat pumps across Garden City. Emergency service is available 24/7. Call (208) 939-2566.
Why is my furnace blowing cold air?
If your furnace is blowing cold air, check your thermostat settings first. Ensure the fan is set to "AUTO" and not "ON." If it's set to "ON," the fan runs continuously even when the heat is off. If the setting is correct, check your filter. A clogged filter can cause the furnace to overheat and shut down the burners while the fan keeps running to cool it off. If neither of these is the issue, you likely have a faulty flame sensor or pilot light and need professional heating service.
Can you repair heaters in manufactured or mobile homes?
Yes, absolutely. Garden City has a high concentration of manufactured homes, and their heating systems have specific requirements regarding venting and airflow. Our technicians are trained to service and repair HUD-approved furnaces specific to mobile and manufactured housing.
How often should I change my filter in Garden City?
Given the dust from the fairgrounds and the pollen from the river corridor, we recommend checking your furnace filter every 30 days during the heating season. If you use a standard 1-inch filter, monthly replacement is often necessary to maintain proper airflow and efficiency.
What is the benefit of a variable-speed furnace?
A variable-speed furnace can run its blower motor at different speeds, rather than just "high" or "off." This allows for quieter operation, better air filtration (since the air cycles more often), and more consistent temperatures throughout the home, eliminating the "hot and cold" blasts associated with older single-stage units.
Is it normal to smell gas near my furnace?
No, smelling raw gas (rotten eggs) is never normal. If you smell gas, evacuate the home immediately and call Intermountain Gas or 911. Do not turn light switches on or off. Once the gas is shut off and the home is safe, call Air Care to pressure test your lines and repair the leak or the gas valve in your furnace installation.
How long does a furnace installation take?
A standard Garden City furnace replacement typically takes one day (6 to 8 hours). If we are modifying ductwork, adding zoning, or moving gas lines, it may take slightly longer. We always aim to have your heat restored before the evening chill sets in.
