Truck HVAC & A/C Service
Light- & Medium-Duty
Whether you drive a work truck for the job or run a small fleet, a cab that won’t cool down or heat up makes an eight-hour shift feel a lot longer. We inspect, repair, and recharge HVAC systems on work trucks and vans.
Where can I get truck HVAC or A/C service in Greeley, CO?
Truck City Service at 1415 1st Ave in Greeley handles HVAC inspection, cabin air filter replacement, A/C compressor and condenser service, refrigerant recharge, and heater core service for light- and medium-duty trucks, vans, and fleets. Factory-trained technicians diagnose the actual cause before recommending a fix. Open Monday through Friday, 7:00 AM to 6:00 PM.
Comfort Is Part Of The Job, Not Extra
A driver who’s sweating through a July route or shivering through a January one isn’t doing their best work. HVAC problems rarely start big. Usually it’s weak airflow or a slow fade in cooling that gets ignored until the system quits altogether.
“The complaint we hear most is that the A/C ‘used to blow colder.’ That’s almost always a slow refrigerant leak, and it’s a lot cheaper to find and fix now than after the compressor seizes from running low for months.”
Sierra, Service Advisor, Truck City Service, Greeley CO
We check the whole system, not just top off refrigerant and send you out the door. An HVAC check is also part of our medium-duty maintenance service, so it’s easy to bundle with other work. If you’re managing more than one work truck, our fleet management program keeps HVAC service history on record across every vehicle.
HVAC Services We Offer
HVAC Inspection
We check airflow, temperature output, and system pressure to find the actual cause before recommending a repair.
Cabin Air Filter Replacement
A clogged filter restricts airflow and lets dust and odors into the cab. A quick swap fixes both.
A/C Compressor & Condenser Service
The compressor and condenser do the actual cooling. When one fails, the whole system loses cold air.
Refrigerant Recharge
We check for leaks first, then recharge to spec. Refrigerant doesn’t run low on its own, a leak is nearly always the cause.
Heater Core Service
A failing heater core means weak heat, a sweet smell inside the cab, or fogged-up windows in cold weather.
Fleet HVAC Tracking
HVAC service history tracked across your whole fleet, so a cab climate problem doesn’t get discovered mid-route.
Parts & Accessories
Compressors, condensers, and cabin filters sized for work trucks and vans, stocked in our parts department.
HVAC Specs Worth Knowing
| What To Check | Spec Or Interval | Why It Matters |
|---|---|---|
| Cabin air filter | Replace every 12,000 to 15,000 miles | A clogged filter cuts airflow and strains the blower motor. |
| Refrigerant level | Checked against manufacturer spec | Low refrigerant almost always means a leak, not normal use. |
| Vent temperature | 35-40 degrees F on max A/C | Anything warmer points to a compressor, condenser, or refrigerant problem. |
| System pressure test | Annually or at first sign of weak output | Catches a slow leak or a failing component before it strands you. |
| Heater core check | Before first cold snap | A weak heater core is a bigger problem in a Colorado winter than a summer without A/C. |
Intervals are general guidance. Duty cycle and how often the vehicle idles affect them, and our advisors can set a schedule around how your trucks actually run.
Signs Your HVAC Needs Attention
- The A/C blows air that’s not as cold as it used to be.
- Airflow feels weak even on the highest fan setting.
- You hear a rattle or squeal when the A/C or heat is on.
- The windows fog up faster than they should in cold weather.
- There’s a sweet smell inside the cab when the heater runs.
- The heat takes longer than a few minutes to warm the cab.
