Truck HVAC System Repair Service
Your cab is your office, and sometimes your home, so a comfortable temperature isn't a luxury. A heater that blows cold air, a defroster that can't clear the windshield, or controls that won't switch modes can make every mile miserable and even unsafe. I-55 Truck & Trailer Repair provides truck HVAC repair at our shop on I-55 in Crawfordsville AR, covering heating, ventilation, and climate controls for drivers across Memphis & West Memphis. We keep your cab comfortable in every season.
Why Choose Us
Year-Round Comfort for Life Behind the Wheel
HVAC problems can come from coolant flow, electrical controls, air doors, or the blower system, and the symptoms often overlap. Our ASE certified mechanics trace the issue through the whole system instead of guessing at parts. We understand how much time drivers spend in the cab, so we treat comfort problems as seriously as mechanical ones. With 25 years of truck repair experience, we get your heat, airflow, and controls working the way they should.
What We Offer
Heating, Airflow, and Climate Control Repairs
A truck's HVAC system ties into the engine cooling system, the electrical system, and the cab's air ducts. We service every part of it to restore reliable comfort and clear visibility. Here's what our HVAC service covers:
Heater Core Repair and Replacement: A clogged or leaking heater core can cause weak heat, foggy windows, or a sweet coolant smell in the cab. We flush or replace the heater core to restore full heating.
Heater Valve and Hose Service: Stuck heater valves and leaking hoses stop hot coolant from reaching the heater core. We replace faulty valves and hoses to get warm air flowing again.
Blend Door and Actuator Repair: Blend doors control the mix of hot and cold air and where it flows. We repair or replace sticking doors and failed actuators so your settings work correctly.
HVAC Control Panel Repair: Unresponsive knobs, buttons, or displays can leave you stuck on one setting. We diagnose control panels and wiring to restore full control.
Defroster System Repair: A working defroster is critical for clear visibility in cold or rainy weather. We repair airflow and heating problems that keep your windshield from clearing.
Blower and Ventilation Service: Weak airflow can come from a failing blower, a bad resistor, or blocked ducts. We find the restriction or electrical fault and fix it.
Cabin Air Filter Replacement: A dirty cabin filter reduces airflow and lets dust and odors into the cab. We replace filters to improve air quality and HVAC performance.
A/C Performance Check: As part of a full HVAC inspection, we check A/C output and system pressures. If deeper A/C work is needed, our semi truck A/C service can handle it.
Frequently Asked Questions
Why is my truck heater blowing cold air?
Common causes include low coolant, a stuck thermostat, a clogged heater core, a faulty heater valve, or a blend door that isn't moving. We test each part of the system to find the problem.
Why won't my truck's defroster clear the windshield?
Weak heat, low airflow, a stuck mode door, or a clogged cabin filter can all reduce defroster performance. Moisture from a leaking heater core can also fog the glass.
What is a blend door, and how do I know if it's bad?
A blend door controls the mix of hot and cold air coming into the cab. If temperatures don't change when you adjust the controls, or you hear clicking behind the dash, the door or its actuator may be failing.
Can a heater problem affect my engine?
Yes. Because the heater uses engine coolant, leaks in the heater core or hoses can lower coolant levels and lead to overheating.
