SERVICES INCLUDED IN AC & HEATING REPAIR
HVAC Diagnostics
Diagnosis of your vehicle’s full heating and cooling system, tracing warm air, weak airflow, or noise complaints to their actual cause.
Air Conditioning Service
Refrigerant recharge, leak detection, and compressor inspection to restore proper cooling, without just masking a leak.
WHY IS MY AC BLOWING WARM AIR?
| Cause | What's Happening | How We Diagnose It |
|---|---|---|
| Low refrigerant | A leak somewhere in the system | Leak detection dye and pressure testing |
| Failing compressor | Compressor not cycling properly | Compressor cycle and pressure testing |
| Electrical fault | Blend door, sensor, or relay issue | Electrical diagnostic scanning |
| Clogged condenser | Airflow blocked, can't dissipate heat | Visual and pressure inspection |
Topping off refrigerant without fixing the leak means you'll be back here again in a few months. We find the actual cause.

Still have a question?
Our team is happy to help. Call us or book a time and we'll walk you through everything.
Why is my car AC blowing warm air?
The most common cause is low refrigerant due to a leak somewhere in the system. It can also be a failing compressor or an electrical issue. We diagnose which one before recommending a repair.
Will topping off my refrigerant fix the problem?
It might work temporarily, but if there's a leak, the refrigerant will leak out again and you'll be back to warm air within months. We recommend diagnosing and fixing the leak itself.
Why is my heat not working but the AC is fine?
This can point to a stuck blend door, a failing heater core, or a coolant flow issue. These are separate systems from your AC, so we diagnose them independently.
How often does a car AC need to be recharged?
A properly sealed system shouldn't need regular recharging. If you're needing frequent recharges, there's likely a leak that should be diagnosed and repaired.
How much does AC repair cost?
Cost depends on the cause, a recharge costs far less than a compressor replacement. We'll diagnose first and give you an itemized estimate before any work begins.
Why does my AC smell bad when I turn it on?
This is often caused by mold or bacteria buildup in the evaporator or ventilation system. We can inspect and recommend a cleaning or service if needed.
