Why Your AC Isn't Cooling
Six Reasons Your AC Runs But Won't Cool
An AC that runs but won't cool is almost always one of six things: a refrigerant leak, a frozen evaporator coil, a clogged air filter, a failed capacitor or contactor, a stuck reversing valve on a heat pump, or a thermostat that's reading wrong. The right diagnostic isolates which one in 30–45 minutes — guessing wastes parts and money, and topping off refrigerant without finding the leak just stretches the same problem into another summer.
We dispatch EPA-certified techs across Riverside and San Bernardino County the same day you call. Every diagnostic includes refrigerant pressure readings, electrical checks on the capacitor and contactor, superheat and subcooling calculations, and a clear written quote before any repair starts. If it's something simple — a stuck thermostat, a clogged filter, a tripped float switch — we'll tell you so and not invent a problem.
If your indoor temp is climbing past 85°F, you have seniors, infants, or pets in the home, or you're already seeing ice on the line set, treat it as an emergency AC repair and call now. Otherwise, schedule same-day and we'll have a tech at your door before the afternoon heat peaks.

Common No-Cool Symptoms
What Your System Is Telling You
Diagnose · Repair · Restore
Match what you're seeing to the most likely cause — then call us to confirm and fix it.
01
Blowing Warm Air
Blower runs, supply vents push room-temp air. Usually low refrigerant, failed compressor capacitor, or contactor not closing.
02
Ice On The Copper Line
Frozen evaporator coil — almost always low refrigerant or restricted airflow from a dirty filter or collapsed duct.
03
Water Pooling Indoors
Condensate drain clog or float switch tripped. The system shuts cooling off to prevent overflow flooding.
04
Outdoor Unit Won't Start
Compressor humming but not running, or fan spinning without compressor — classic capacitor failure.
05
Short-Cycling (On/Off Fast)
Compressor runs 2 minutes, shuts off, restarts. Refrigerant pressure imbalance or oversized system.
06
One Room Hotter Than Others
Duct leak, zoning damper stuck, undersized return, or restricted register feeding that room.
07
Weak Airflow Everywhere
Dirty filter, dirty blower wheel, collapsed flex duct, or a failing blower motor (ECM or PSC).
08
Thermostat Blank Or Wrong
Bad batteries, tripped low-voltage fuse, or a thermostat reading temp from a sun-heated wall.

Systems We Diagnose
Every No-Cool Scenario
01
Central Split Systems
Outdoor condenser + indoor air handler — the most common Inland Empire no-cool call.
02
Ductless Mini-Splits
Single-zone and multi-zone — inverter compressors, indoor head sensor faults, communication errors.
03
Heat Pumps
Reversing valve stuck in heat mode, defrost board failure, low refrigerant in cooling mode.
04
Package Units
Rooftop and ground-mount — capacitor, contactor, and compressor diagnostics without entering the home.
05
Smart Thermostats
Nest, Ecobee, Honeywell, Sensi — wiring, C-wire, and configuration faults that cause no-cool symptoms.
06
Airflow Restrictions
Filter, blower wheel, duct collapse, return undersizing — the silent cause of 'low refrigerant' calls.
What To Expect
Our Diagnostic Process
- 01
Call & Schedule
A real dispatcher answers — no phone tree. We confirm same-day or next-morning ETA and text the tech's name and photo before arrival.
- 02
On-Site Diagnostic
Flat-rate, no-surprise diagnostic. Tech checks refrigerant pressures, electrical, airflow, and controls — then explains what's failing in plain English.
- 03
Written Quote
You see the repair (or replacement) price before any work starts. Diagnostic fee credits toward the repair when you proceed.
- 04
Repair Or Install
Most repairs are completed same-visit — we stock capacitors, contactors, motors, and refrigerant on the truck. Larger jobs are scheduled within 24–48 hours.
- 05
Test & Document
We verify supply temps, refrigerant subcooling/superheat, and amp draw. You get a written invoice with everything we did, parts used, and warranty terms.

No-Cool FAQ
AC Not Cooling Questions
01
Why is my AC running but blowing warm air?
Most common causes: refrigerant leak, failed compressor capacitor, dirty filter restricting airflow, or a thermostat in HEAT instead of COOL mode. A 30-minute diagnostic isolates which one.
02
What should I check before calling a tech?
Confirm thermostat is on COOL and set 5°F below room temp. Replace the air filter if it's gray. Check the breaker for the AC. If those don't fix it within an hour, call us.
03
Why is my AC frozen up?
A frozen evaporator coil is almost always low refrigerant from a leak, or restricted airflow from a clogged filter or collapsed duct. Shut the system off, let it thaw 4–6 hours, and call a tech — running it frozen damages the compressor.
04
Can low refrigerant just be 'topped off'?
No — refrigerant doesn't get used up like fuel. If it's low, there's a leak. We find and repair the leak, evacuate the lines, then weigh in the exact factory charge. Topping off without repair is illegal under EPA rules and wastes your money.
05
How much does it cost to fix an AC that's not cooling?
Capacitor or contactor replacement runs $250–$450. Refrigerant leak repair + recharge runs $400–$1,200 depending on the leak location. Compressor replacement runs $1,500–$3,000. We always quote before work begins.
06
How long until my house cools down after repair?
On a 95°F+ day, a healthy system drops indoor temp about 1°F every 10–15 minutes. From 88°F to 75°F usually takes 2–3 hours of continuous runtime — that's normal, not a sign of a bad repair.
07
What cities in the Inland Empire do you serve?
Every city in Riverside and San Bernardino County — Riverside, San Bernardino, Fontana, Rancho Cucamonga, Ontario, Corona, Moreno Valley, Temecula, Murrieta, Redlands, Hesperia, Victorville, and the Coachella Valley. See the full service-area list at the bottom of this page.
08
Should I get on a maintenance plan?
If you want to avoid summer breakdowns, yes. Plan members get spring tune-ups, priority dispatch, and discounts on parts and labor. See AC maintenance plans.
09
When does it make sense to replace instead of repair?
If the system is 12+ years old, the repair quote is over 40% of replacement cost, or it still runs on R-22 refrigerant, replacement is usually the better long-term call. See AC replacement for honest math both ways.
