24/7 Heating Repair • Gas Furnace Service • Carbon Monoxide Safe
Boise winters drop below freezing for weeks. Here's what we fix when your heat goes out.
Failed ignitor or flame sensor is the top Boise no-heat call. We carry both on the truck — usually fixed in one visit.
From $200We camera-inspect for cracks — a carbon monoxide hazard. Free safety check with every furnace call.
Safety FirstNo air movement? Blower motors wear out in hard Boise winters. We repair or replace same-day.
From $500Cold spots, short cycling, or a valve that won't open. We diagnose gas pressure and controls precisely.
From $150A frozen Boise night with no heat is an emergency. We answer at 2am and average 90 minutes to your door — no overtime charge, ever.
Every furnace call includes a heat-exchanger camera inspection and CO test. Your family's safety is non-negotiable. A cracked exchanger means the unit is pulled offline immediately.
Our freeze-thaw cycles stress metal and crack ignitors. We stock the parts Boise furnaces actually fail on, so you're not waiting in the cold for a shipment.
$89 diagnostic, waived with repair. Most furnace fixes land $200-$700. You approve the price before we start — no surprises on a holiday weekend.

"Furnace died at midnight during a freeze. Diamond had a tech out by 1:15am, found a cracked heat exchanger, and got us safe and warm. They probably saved our lives."
"Flame sensor went out on Christmas Eve. No overtime charge, fixed in 40 minutes. This is the only HVAC company I'll call."
"Honest about a $600 repair vs $5,000 replacement. Walked me through the math and never pushed the upsell. Rare these days."
Boise's single-digit freezes are brutal on ignition systems. The most common cause is a failed hot-surface ignitor or dirty flame sensor — both of which we stock on every truck. Sometimes it's a tripped high-limit switch from a clogged filter restricting airflow. We diagnose the real cause, not just the symptom, so the heat stays on.
Most Boise furnace repairs run $200-$700. Ignitor $200-$350, flame sensor cleaning/replacement $150-$280, gas valve $400-$700, blower motor $500-$900. Our $89 diagnostic is waived with the repair. If the heat exchanger is cracked on a 15+ year old unit, replacement is usually the safer, cheaper-long-term call — see our furnace installation page.
You usually can't — that's the danger. A crack is silent and leaks carbon monoxide into your airstream. Warning signs: soot around the furnace, a sulfuric or formaldehyde smell, headache/fatigue when the heat runs, or a furnace that short-cycles. We use a camera scope plus a CO meter on every call. If you have an old furnace and no working CO detector, call us today — and consider the Diamond Plan for annual safety inspections.
Yes. Boise city homes are mostly natural gas; outlying areas like Kuna and Middleton have more propane. We service both, plus dual-fuel heat pump systems. Tell us your fuel type when you call so we bring the right fittings and manometer.
