The shop supports drivers throughout Missoula and nearby communities who need dependable HVAC performance without dealership pricing or rushed diagnostics.

Schedule your heating and AC repair in Missoula and restore the climate control your vehicle was designed to provide.

Details That Matter Most

Your HVAC diagnostic begins with testing refrigerant pressure, airflow temperature, and compressor engagement to determine whether the issue stems from a leak, electrical fault, or mechanical failure. Technicians inspect blend doors, heater cores, and evaporator coils for blockages or damage. In Missoula, where cabin heating is essential from October through April, identifying weak heater core flow or stuck blend doors prevents cold mornings and unsafe windshield defrost.

You can expect clear communication about which component failed and why it affects your comfort. Auto Assist Co. uses refrigerant recovery machines, vacuum pumps, and pressure gauges to service AC systems safely and accurately. Experience from dealership and custom-build environments ensures proper handling of refrigerant, compressor, and blend-door diagnostics.

After diagnosis, technicians repair leaks, replace compressors or heater cores as needed, and recharge AC systems to manufacturer specifications. All work follows EPA refrigerant handling standards and uses quality replacement parts matched to your vehicle's HVAC design. Whether your vehicle uses R-134a or R-1234yf refrigerant, the repair approach maintains system efficiency and longevity.

Black checkmark.
How do I know if my AC system has a refrigerant leak?
You'll notice warm air from the vents, reduced cooling over time, or visible oil residue near AC lines and the compressor. Technicians use pressure testing and UV dye to locate leaks before recharging the system.
Black checkmark.
Why is my heater blowing cold air in winter?
Cold air from the heater usually indicates low coolant, a clogged heater core, or a stuck blend door. Technicians test coolant flow and actuator function to identify the cause and restore cabin heat.
