Why is my AC running but not cooling in Burbank?

Common causes include low refrigerant levels, dirty condenser coils, failed compressor, restricted airflow from dirty filters, or thermostat issues. Our technicians diagnose the exact problem and provide upfront repair pricing.

How long does AC repair take?

Most AC cooling issues can be repaired in 1-3 hours. Compressor replacements or refrigerant leak repairs may take longer. We carry most parts on our trucks for same-day completion.

What does AC repair cost in Burbank?

Simple fixes like capacitors run $150-$350. Refrigerant recharge $350-$900. Compressor replacement $1,200-$2,500. We always diagnose first and provide clear pricing before any work.

Can I fix my AC not cooling myself?

Start by replacing your air filter, checking the thermostat setting, and ensuring the outdoor unit isn't blocked by debris. If those don't work, call a professional—refrigerant and electrical issues require licensed technicians.

Is it dangerous to run my AC if it's not cooling?

Running an AC that's not cooling can cause further damage, especially if the issue is low refrigerant (can damage compressor) or a failing compressor (can overheat electrical components). Turn it off and call for service.

AC Not Cooling in Burbank, IL? We Fix It Fast

Is your air conditioner running but not cooling your Burbank home? You're not alone—this is one of the most common AC problems we solve. Clucas Mechanical provides same-day diagnosis and repair so you can get back to comfort quickly.

Why Your AC Runs But Won't Cool

When your AC blows warm or lukewarm air, the problem usually falls into one of these categories:

1. Low Refrigerant (Most Common)

Your AC needs the right amount of refrigerant to absorb heat from your home. If refrigerant is low due to a leak, the system can't cool effectively. Signs include ice forming on the copper lines outside or at the indoor coil.

What we do: Find and repair the leak, then recharge refrigerant to manufacturer specifications. We use electronic leak detectors and pressure testing—no guessing.

2. Dirty or Blocked Condenser Coils

The outdoor unit (condenser) releases heat absorbed from your home. If the coils are clogged with cottonwood seeds, grass clippings, or dirt—common in Burbank's late spring and summer—the unit can't reject heat efficiently.

What we do: Clean coils with professional coil cleaner and high-pressure rinse. Often restores cooling immediately.

3. Failed Compressor or Capacitor

The compressor is the heart of your AC system. If it's failed or struggling due to a bad capacitor, the refrigerant won't circulate properly. You might hear buzzing, humming, or clicking from the outdoor unit.

What we do: Test capacitor and compressor function. Replace capacitor same-visit if failed ($150-$350). For compressor failure, we provide honest repair vs. replacement guidance.

4. Restricted Airflow

A severely clogged filter, closed supply vents, or duct blockages prevent proper airflow. The evaporator coil may freeze, further reducing cooling.

What we do: Check filter, airflow, and static pressure. Identify and clear restrictions. Thaw frozen coils safely before restarting system.

5. Thermostat Problems

If your thermostat isn't reading temperature correctly, has dead batteries, or has faulty wiring, your AC may run continuously without cooling your home to the set temperature.

What we do: Test thermostat calibration and wiring. Replace or upgrade as needed, often same-day.

Burbank-Specific AC Challenges

Many Burbank homes were built in the 1950s-1970s with original or partially updated ductwork. Common issues we see:

Undersized return ducts: Starves the AC of airflow, reducing cooling capacity by 20-30%
Leaky ductwork in unconditioned spaces: Loses 15-40% of cooled air before it reaches your rooms
Single return for multi-story homes: Creates pressure imbalances and hot upstairs, cold downstairs
Aging equipment paired with new thermostats: Compatibility issues causing short cycling

We don't just fix the immediate problem—we look at the whole system to prevent repeat failures.

Our AC Repair Process

Rapid Response: Most Burbank calls get same-day service. We call ahead 15-30 minutes before arrival.
Thorough Diagnosis: We test electrical components, refrigerant charge, airflow, and controls—not just swap parts.
Clear Explanation: You'll understand what failed, why, and what options you have.
Upfront Pricing: Written estimate before we start work. No surprises.
Quality Repair: OEM or better parts. Clean workspace. 1-year workmanship warranty.
Post-Repair Testing: We verify proper cooling, airflow, and temperature drop before we leave.

What AC Repair Costs in Burbank

Pricing varies by problem:

Diagnostic visit: $89-$149 (waived if you proceed with repair)
Capacitor or contactor replacement: $150-$350
Refrigerant leak repair and recharge: $350-$900
Blower motor or fan motor: $450-$900
Compressor replacement: $1,200-$2,500 (we'll discuss replacement vs. repair)
Coil cleaning (condenser or evaporator): $150-$400

For systems 12+ years old requiring major repairs, we'll compare repair costs against replacement with a high-efficiency system that can lower your energy bills by 30-40%.

DIY Checks Before You Call

Save time and maybe solve the problem yourself:

Replace your air filter if it's dirty or clogged. A $5 filter might restore cooling.
Check your thermostat: Ensure it's set to COOL, temperature is below current room temp, and fan is set to AUTO (not ON).
Check the outdoor unit: Make sure it's running, the area is clear of debris, and the disconnect switch is on.
Check your circuit breakers: AC systems have two breakers—one at the panel, one near the furnace. Ensure both are on.
Give it time after a reset: If you reset breakers, wait 30 minutes before expecting cool air (system needs time to stabilize).

If these don't work, call us. Refrigerant and electrical issues require professional tools and licensing.

When to Replace Instead of Repair

We're honest about repair vs. replacement. Consider replacement if:

Your AC is 12-15+ years old AND needs a major component (compressor, coil)
Repair costs exceed 50% of replacement value
Your energy bills have climbed significantly
You've had multiple repairs in the last 2-3 years
Your home never gets comfortable even when the AC runs constantly

New high-efficiency systems (16+ SEER) can cut cooling costs by $300-$800/year compared to old 10 SEER units common in Burbank.
