HVAC Repair in the Greater Boise Area

Your AC can run without cooling due to a clogged air filter, blocked outdoor unit, incorrect thermostat settings, low refrigerant, a frozen coil, or duct problems. If airflow feels weak or warm in Boise or Nampa, these are likely causes.

Quick checks:

• Set thermostat to Cool and Auto.
• Replace a dirty filter (check monthly).
• Clear 2–3 ft around the outdoor condenser.
• Open all supply/return vents.
• If you see ice on lines, turn AC off, set fan to On to thaw, then call.

An air conditioner not turning on with the thermostat set to Cool usually indicates a power, control, or safety shutdown issue. The most common cause is a tripped breaker or the indoor unit power switch off, so the system never gets power. Other frequent triggers include a full condensate pan activating a float switch, a blown low‑voltage fuse from a short, or a failed thermostat. We see these start‑up problems regularly in homes around Kuna and the greater Treasure Valley. If the outdoor fan doesn’t even twitch when cooling is called, the 24‑volt signal likely isn’t reaching the contactor.

Try these quick checks before calling:

• Confirm thermostat is on Cool, set below room temp, and has fresh batteries.
• Reset the AC/furnace breaker once and ensure the furnace switch is on.
• Empty the condensate pan or check the pump for power.
• Replace a clogged air filter to restore airflow.

Do not keep resetting a breaker that trips again; a short can damage the compressor. <br/> Updated: 2026-06-07 <br/> Need help in Kuna, ID? Call (208) 738-4822 or book online. "We do not delay service calls... [Ultimate Heating & Air] arrived less than an hour later" — James W.

Your AC may run but not cool due to a clogged filter, dirty outdoor coil, low refrigerant, a bad capacitor, or the thermostat set to “fan.” Closed or blocked vents and frozen coils also reduce cooling. Ultimate Heating & Air offers 24/7 diagnostics and repairs in Boise, Nampa, and Caldwell.

Quick checks:

• Set thermostat to Cool and Auto.
• Replace or clean the filter.
• Clear debris around the outdoor unit.
• Open all supply and return vents.
• If coils are iced, turn system off.

HVAC repairs feel expensive because they combine expert labor, advanced system diagnostics, quality parts, and sometimes 24/7 emergency response. Complex or older systems can need multiple components, increasing time and parts costs. After-hours or same-day service adds cost. Serving wide areas like Boise, Nampa, and Meridian also requires stocked parts and travel readiness. You can reduce costs with our plans: Premium Plan gives up to 25% off repairs and no after-hours fees; Ultimate Plan waives diagnostic charges. Coupons like $49 repair diagnostics may be available.

There isn’t a single “average” furnace repair cost; final pricing is confirmed after diagnosis because parts, system design, and labor vary case by case, and Ultimate Heating & Air provides upfront, itemized pricing following a $99 Furnace Repair Diagnostic. The biggest swings in cost come from major component failures and hard-to-reach equipment, while minor control issues tend to be less. We handle these repairs every day for homes around Boise and nearby communities. Before any work starts, you’ll get a written report with options, and we charge no service or dispatch fees. Seasonal promotions, including repair discounts, may apply.

What most affects your final cost:

• Part price differences and availability
• Labor time for access, repair, and testing
• System age and warranty status
• Code or safety corrections discovered during diagnosis

If you smell gas or see scorch marks, turn off the furnace and call a licensed technician immediately. <br/> Updated: 2026-05-24 <br/> Need help in Boise, ID? Call (208) 738-4822 or book online. “Knowledgeable, responsive, friendly, transparent and they show up on time.” — Allison.

Same-day HVAC repair costs vary by the fault, parts, and timing. We start with a diagnostic; promotions as low as $49 are available for many systems. Members on select plans may pay $0 for diagnostics and never pay after-hours fees. Emergency repair is available 24/7. After the diagnostic, your technician presents options and prices before work begins. Maintenance plans can include up to 25% off repairs and an up to 10-year repair warranty. We serve Boise, Nampa, Caldwell, and the Treasure Valley.
