Professional AC Repair
When your air conditioner isn't cooling, Islas Heating & Cooling diagnoses the system first, explains what we found, and recommends a repair based on what the equipment actually needs — across our Inland Empire service area.
Is Your AC Having One of These Problems?
These symptoms can have several possible causes. A technician needs to inspect and test the system to determine the actual problem — we don't guess.
We Diagnose Before We Recommend
An air-conditioning symptom — warm air, weak airflow, short cycling, or a system that won't start — can come from more than one part of the system. That's why we evaluate the whole cooling system, test the relevant components, and base our recommendation on what we actually find.
You get clear findings and honest options — repair when it makes sense, replacement when the system's condition makes it the more reasonable investment. No pressure, no guesswork.
Diagnostic Service Fee — $75
Our current HVAC diagnostic/service fee is $75. The fee covers diagnosing the system, identifying the issue, and providing a repair estimate. If you proceed with the approved repair, the diagnostic fee is applied toward the repair according to current company policy. This is a diagnostic visit — not a "free estimate."
Common AC Problems & Components
Any of these may be involved in a cooling problem — diagnosis determines which one is actually causing it.
Capacitor
A failed or weakening capacitor can prevent the fan or compressor from starting. Testing identifies whether it's the actual cause.
Contactor / Electrical
Pitted or sticking contactors and wiring faults can interrupt operation. Electrical components are tested as part of diagnosis.
Condenser Fan
A fan that won't run or runs erratically can affect heat rejection. Inspection determines whether the fan motor or a control is the issue.
Blower / Airflow
Weak airflow can come from a blower issue, a dirty filter, or a duct restriction. Airflow is measured, not guessed.
Thermostat / Controls
A thermostat or wiring fault can stop the system from starting or reaching setpoint. Controls are checked during the diagnostic.
Drainage
A clogged drain line can cause water around the indoor equipment and trip safety switches. The drain is inspected and cleared as needed.
Dirty / Restricted Coils
A dirty indoor or outdoor coil reduces cooling performance and can cause freezing. Coil condition is part of the evaluation.
Refrigerant Circuit
Low cooling can involve a refrigerant-circuit condition or a leak. Refrigerant work requires proper diagnosis — adding refrigerant alone doesn't fix an underlying leak.
Compressor
Compressor problems can stop cooling entirely. Testing determines whether the compressor or a control feeding it is the root cause.
What Happens During an AC Service Visit
You explain the concern
Tell us what you're seeing or hearing — symptoms and when they started.
We evaluate the system
The technician inspects the indoor and outdoor equipment and relevant controls.
Relevant tests are performed
Electrical, mechanical, refrigerant, and airflow conditions are tested as applicable to the symptom.
We identify the likely root cause
Findings are based on what the tests show — not a guess.
Findings and options are explained
We show you what we found and present clear repair or replacement options.
You receive repair investment info
Pricing is explained before any work begins.
Work proceeds only after your approval
Nothing is repaired or replaced until you say go.
Not every test applies to every job — the technician performs the checks relevant to your symptom and system.
What Happens After Diagnosis
Once the root cause is identified, we explain the findings in plain language and present your options — a specific repair, a repair with a replacement consideration, or, if the system supports it, a full replacement evaluation. You see the repair investment before any work begins, and nothing is repaired or replaced until you approve it.
Repair vs Replacement
We don't push replacement. When you're weighing it, we look at the system's condition, age, repair history, the current repair investment, reliability, comfort, efficiency, safety, and parts availability — then help you decide whether repair or replacement is the more reasonable investment for your home.
A single honest recommendation: repair when it makes sense, replace when the system's condition makes replacement the better long-term investment.
Compare Repair vs ReplaceFactors We Consider
- Equipment age
- Current condition
- Repair history
- Current repair investment
- Reliability

- Safety
- Parts availability
- Your long-term plans
Free Replacement Estimates
Complete HVAC system replacement estimates are free when the visit is specifically for gathering replacement information — evaluating your needs, taking pictures, and preparing a replacement proposal. That's different from a diagnostic visit, which addresses an existing system problem. Tell us which type of visit you need when you schedule.
