Common AC Problems We Fix

AC Not Cooling or Blowing Warm Air

Refrigerant Leaks: Low refrigerant reduces cooling capacity. You might notice ice on indoor coils or the system running constantly without cooling properly. We locate leaks, repair them, and recharge your system to manufacturer specifications.

Failed Compressor: The compressor circulates refrigerant through your system. When it fails, your outdoor unit may hum or click but won’t start, or it runs briefly then shuts off. We diagnose compressor issues and provide repair or replacement options.

Dirty Coils: Monsoon dust coats outdoor coils, preventing heat release. Your system runs constantly, energy bills spike, but cooling drops significantly. We clean coils thoroughly to restore proper heat transfer.

System Won’t Turn On

Bad Capacitors: Extreme heat causes frequent capacitor failures in Tucson. These store electrical energy to start your compressor and fans. When they fail, motors hum but don’t start. Quick, affordable repair prevents motor damage.

Thermostat Problems: Failed thermostats can’t signal your system to start. During heating system installation, we test all connections, verify proper operation, and replace faulty units when needed.

Electrical Issues: Tripped breakers, blown fuses, or faulty wiring prevent operation. We diagnose why breakers trip rather than just resetting them, protecting against fire hazards.

Strange Noises

Grinding or Squealing: Indicates bearing failure in motors. Requires prompt repair before complete motor failure occurs.

Banging or Clanking: Loose or broken fan blades, failing internal components. Gets worse rapidly if ignored.

Hissing: Often indicates refrigerant leaking from your system. Requires immediate attention.

Frequent Cycling On and Off

Wrong System Size: Oversized units cycle too frequently, wasting energy and wearing out components. May require replacement.

Low Refrigerant: Causes abnormal pressures triggering safety switches that shut down the system.

Restricted Airflow: Dirty filters or blocked vents cause the indoor coil to freeze, creating short-cycling. Often fixed with filter changes and cleaning.

High Energy Bills

Worn Components: Aging parts lose efficiency, requiring more electricity for the same cooling.

Duct Leaks: Waste 20-30% of cooled air in attics where temperatures exceed 140°F. We seal leaks and repair damaged sections.

Dirty System: Clogged filters and dust-covered coils make your AC work harder, running longer to achieve comfortable temperatures.

Frozen Coil or Lines

Blocked Airflow: Clogged filters or failed blower motors reduce airflow across the coil, causing ice buildup.

Refrigerant Loss: Low refrigerant from leaks causes excessive temperature drops and ice formation.

Operating with frozen coils risks water damage and compressor failure. Requires immediate professional repair.

Our Repair Process

1. Fast Response

Same-day emergency service available. We prioritize calls during extreme heat, understanding the health risks when indoor temperatures climb above 90°F.

2. Accurate Diagnosis

We use diagnostic tools to identify root causes:

• Temperature and pressure testing for refrigerant issues
• Electrical testing on all components
• Airflow measurement and duct inspection
• Complete system evaluation

3. Transparent Pricing

Before starting work, you receive a clear estimate including:

• Specific parts needed
• Labor costs
• Total repair price
• Priority level (critical now vs. can wait)

No surprise charges. No upselling unnecessary services.

4. Quality Repairs

Our technicians repair all major AC brands with quality parts designed for extreme heat. We follow EPA regulations for refrigerant work, meet electrical codes for safety, and test thoroughly before finishing.

5. Complete Testing

After repairs, we verify:

• Proper system pressures and temperatures
• Correct electrical current draw
• No abnormal noises or vibrations
• Adequate cooling throughout your home

When to Call Immediately

Emergency situations requiring immediate service:

• No cooling when temperatures exceed 100°F
• Burning smell or smoke from vents
• Sparking or repeatedly tripped breakers
• Water leaking from indoor unit
• Loud grinding or banging noises

Shut off your system at the breaker if you notice electrical problems or burning smells, then call us immediately.

Repair or Replace? Honest Guidance

Repair makes sense when:

• Your system is under 10 years old
• Repair costs less than 50% of replacement
• It’s a minor component like a capacitor or fan motor
• The system has been reliable with minimal past repairs

Replacement may be better when:

• Your AC is over 15 years old
• Major component failure (compressor, coil)
• Frequent repairs in recent years
• Uses obsolete R-22 refrigerant because it phased out
• Energy bills are excessive despite repairs

We provide honest recommendations based on your situation, not sales commissions.

Typical Repair Costs in Tucson

Minor Repairs: $150-$400

• Capacitors, contactors, thermostats
• Common failures, straightforward fixes

Moderate Repairs: $400-$1,000

• Fan motors, control boards, small leaks
• Several hours of skilled labor

Major Repairs: $1,500-$3,500

• Compressor or coil replacement
• Consider replacement at this cost level

Emergency service after hours adds $75-$150. Fair pricing for immediate relief during extreme heat.

Preventing Future Breakdowns

Simple steps reduce repair needs:

Change filters monthly during heavy use. Tucson’s dust clogs filters quickly.

Keep outdoor unit clear of debris and vegetation. Rinse off dust after monsoon storms.

Schedule maintenance twice yearly (before summer, after monsoons). Catches problems early and maintains efficiency.

Address problems promptly. Strange noises or reduced cooling indicate developing issues. Early repair costs less than emergency failures.
