Littleton, CO
From a weak AC recharge to a failed heater core — AutoTrek diagnoses and repairs the full climate control system. Stay comfortable year-round with service from ASE Certified technicians who know Colorado's temperature extremes.
What's Included
AutoTrek services every component of your vehicle's heating and cooling system — from the compressor to the cabin air filter.
We evacuate old refrigerant, check for moisture contamination, and recharge to the exact manufacturer specification using R-134a or R-1234yf refrigerant.
Using electronic leak detectors and UV dye, we locate refrigerant leaks at the compressor, condenser, evaporator, hoses, and fittings before recharging the system.
The AC compressor is the heart of the system. We diagnose compressor failure, replace with quality parts, and flush the system before recharging to prevent repeat failures.
A leaking heater core causes a sweet smell, foggy windshield, or wet carpet. We flush or replace the heater core and check the coolant system for related issues.
Stuck blend door actuators prevent proper temperature control. Failed blower motors mean no airflow. We diagnose and replace both quickly and accurately.
A clogged cabin filter reduces airflow through your HVAC system and allows allergens and debris into the cabin. We inspect and replace it during every AC service.
Why It Matters
Littleton's climate swings from sub-zero winter mornings to 100°F summer afternoons. A failing AC or heater isn't just uncomfortable — it's a safety issue. A fogged windshield from a leaking heater core reduces visibility. A broken defroster compromises ice removal in winter.
Don't wait until the hottest day of summer or a January cold snap to find out your climate control isn't working. AutoTrek recommends having your AC performance tested each spring and your heating system checked each fall — before you need them most.
Schedule ServiceWarning Signs
AC blowing warm or barely cool air — low refrigerant from a leak, or a failing compressor.
Weak airflow from vents — clogged cabin filter, failing blower motor, or blocked ductwork.
Sweet or musty smell from vents — sweet smell indicates a heater core leak; musty smell means mold on the evaporator.
Foggy or wet carpet on passenger side — a classic sign of a leaking heater core inside the dashboard.
Loud noise when AC is turned on — often a worn AC compressor clutch or debris in the blower motor.
Temperature controls not responding — faulty blend door actuator or climate control module failure.
Our Process
We measure vent temperatures, system pressures, and blower output. This tells us whether you need a simple recharge or a deeper component repair.
Using electronic detectors and UV dye, we scan every joint, seal, hose, and component for refrigerant or coolant leaks before any recharge.
We repair or replace only what's failed — compressor, condenser, evaporator, heater core, blend door, or blower motor — with quality parts.
After every AC service, we verify vent temperatures meet manufacturer specs before returning your vehicle. Cold should be cold. Hot should be hot.
AC recharge service typically ranges from $129–$199 depending on refrigerant type and system capacity. Component repairs (compressor, condenser, heater core) are quoted after diagnosis. We never recharge a leaking system without finding and fixing the leak first. Call (303) 328-3356 for a quick quote.
