Refrigerant recharge
Both R-134a and R-1234yf machines on site. Correct charge by weight, not by guess.
A/C Service
Auto A/C Service and Repair in Boulder, CO
Cold air, no mystery. Full A/C system service for Boulder's brutal sun and high-altitude summer drives.
Full automotive A/C service including R-134a and R-1234yf refrigerants, leak detection, compressor work, condenser and evaporator service, cabin filters, and heater core repair. We diagnose before we recharge so you fix the cause, not the symptom.
Complete A/C system service.
A failed A/C is rarely just low refrigerant. We service the full system so the cold air comes back and stays back.
Leak detection
UV dye and electronic sniffers locate leaks at fittings, hoses, evaporators, and condensers.
Compressor service
Diagnosis, clutch repair, and full compressor replacement with proper system flushing.
Condenser and evaporator
Replacement when impacted by road debris or corrosion. Critical for cooling efficiency.
Cabin air filter
Often forgotten and often the cause of weak airflow and musty smells. Quick to swap.
Heater core service
When you smell sweet coolant or see fog from the vents, the heater core is leaking. We fix it right.
How to tell your A/C is in trouble.
If you notice any of the following, do not wait. Small issues become expensive ones quickly.
- Weak airflow even on the highest fan setting
- Warm air at full cold setting
- Strange smells, musty or sweet, from the vents
- Hissing or clicking sounds from the dash
- A/C light blinking on the climate panel
- Sweet coolant smell from a leaking heater core
How an A/C service runs at Legacy.
Performance test
Vent temperature, system pressures, and compressor cycling tested at the start.
Leak detection
UV dye and electronic sniffer to locate the source. Photos of every leak found.
Diagnose root cause
Low refrigerant has a reason. We find it before we add a single ounce.
Repair with OEM-spec parts
Compressor, condenser, hoses, and seals to factory specification, properly flushed.
Recharge and verify
Vacuum the system, recharge to spec by weight, retest pressures and vent temperature.
Why drivers bring A/C work here.
Both refrigerant systems on site
R-134a for older vehicles and R-1234yf for newer. We service the car you actually drive.
Diagnose before recharge
No recharge-and-pray. We find the leak first so the refrigerant you pay for stays in the system.
Warranty on A/C work
Three-year, thirty-six-thousand-mile NAPA warranty applies to qualifying A/C repairs.
Photo documentation of leaks
You see the leak point on screen before we propose the repair. No guessing, no mystery.
Mile-high roads ask more of every vehicle.
Boulder summer plus thin air at altitude works your A/C system harder than coastal driving. We see compressors that are tired before their time and refrigerant pressures that look different than sea-level spec.
Altitude
Lean-running engines, harder-working turbos, and drivetrains that climb every commute.
Freeze cycles
Repeated thaw and refreeze chews through seals, hoses, batteries, and brake hardware.
UV and dust
High-altitude sun and grit accelerate paint, plastics, glass, and intake fouling.
Frequently Asked Questions
Most often a partial refrigerant loss or a failing compressor. Sometimes a clogged cabin filter restricts airflow. Sometimes the blend door actuator is mixing in warm air. We test pressures and airflow to find which one applies before we propose work.
