A/C Service & Repair

Light- & Medium-Duty

Northern Colorado summers turn a cab into an oven fast. Our factory-trained techs diagnose and fix A/C systems on light- and medium-duty trucks — refrigerant leaks, compressor failure, clogged cabin filters — so your drivers stay focused, not sweating.

Quick Answer

Weak or warm airflow usually traces to a clogged cabin air filter, a refrigerant leak, or a failing compressor/condenser. Truck City Service diagnoses the actual cause — not just a recharge — and repairs light- and medium-duty A/C systems with OEM parts in Greeley, CO.

Why A/C Problems Cost More the Longer You Wait

Technician performing an A/C diagnostic on a pickup truck

A/C trouble rarely stays small. A slow refrigerant leak today is a seized compressor next month — and a compressor failure can send metal debris through the whole system.

A recharge without a diagnosis is a 30-day fix, not a repair.

“More trucks come in with a system that’s been ‘recharged’ twice already than come in fresh. If nobody found the leak, it’s back in a month — and now the compressor’s worn from running low.”

— From our service bay, Truck City Service

Common A/C Problems We Diagnose

Airflow

Clogged Cabin Air Filter

Dust, pollen, and mold spores build up over time and choke output. Usually a quick, inexpensive fix.

Cooling

Refrigerant Leak

Refrigerant absorbs and sheds heat as it cycles. A leak means less refrigerant and a cabin that won’t cool. We trace the source, repair it, and recharge to spec.

Mechanical

Compressor or Condenser Trouble

The compressor moves refrigerant; the condenser sheds heat from it. A clogged condenser can often be cleaned — a damaged compressor typically needs replacement.

!Medium-duty is the largest class we service. We do not service Class 7–8 big rigs / semis or large motorhomes. Not sure where your truck falls? Call us and we’ll tell you straight.

Signs Your A/C Needs Attention

  • Warm air even at max setting
  • Weak airflow from the vents
  • Musty odor when the A/C runs
  • Clicking or grinding when the compressor engages
  • Visible refrigerant residue near hoses or fittings
  • A/C cycling on and off rapidly

Frequently Asked Questions

Why is my truck’s A/C blowing warm air?
Most often a refrigerant leak, a failed compressor, or a clogged cabin air filter. We run a full diagnostic before recommending a repair.
How much refrigerant does my vehicle need?
It depends on the make and system. We charge to the manufacturer’s specification after confirming there’s no active leak.
Can a cabin air filter really affect A/C performance?
Yes. A clogged filter restricts airflow across the evaporator, which can make a healthy system feel weak even with no leak present.
Do you service A/C on medium-duty trucks?
Yes — light- and medium-duty trucks are our core focus. We do not service Class 7–8 big rigs or large motorhomes.
How long does an A/C diagnostic take?
A standard diagnostic typically takes under an hour; a full leak trace can take longer depending on the system.
What happens if I just get a recharge without a diagnosis?
If there’s an active leak, the system will lose charge again within weeks and the compressor can wear from running low on refrigerant.
Do you use OEM parts for A/C repairs?
Yes, our factory-trained technicians install OEM-quality parts to keep the repair to factory spec.
