Answers to Common Questions
View All FAQsWhy Is My Air Conditioner Running But Not Cooling Properly?
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.

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.

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.
