Truck, bus & coach HVAC

Truck, bus and motor coach HVAC and A/C repair in Halifax and Truro

A cab with no A/C in July or a coach with fogged glass in January is a problem for the driver and the passengers. We repair air conditioning, heating, defrost and ventilation on trucks, buses and motor coaches at your yard or wherever the vehicle is parked.

Truck and bus A/C repair for drivers and passengers

A driver sitting in a hot cab all afternoon, a coach of passengers with no cooling, or a windshield that will not clear on a frosty morning all need fixing before the unit goes back out. Air conditioning problems tend to show up on the first hot day of summer and heater problems on the first cold morning, and we can usually track them down and fix them on site the same day.

HVAC repair for trucks, buses and motor coaches

A coach HVAC system is much larger than a truck's, with multiple heaters, evaporators and blowers and long coolant and refrigerant runs to the back of the bus. Ryon's coach background with Prevost, MCI and Van Hool covers those systems, and the same van handles the mechanical side of trucks, buses and coaches too.

We repair truck, bus and coach HVAC and A/C systems across Halifax, Dartmouth, Bedford, Hammonds Plains, Lower Sackville and Mount Uniacke, and up the 102 through Fall River, Enfield, Elmsdale and Stewiacke to Truro. Fleets can add spring A/C checks and fall heater checks to a fleet maintenance contract so problems are found before the season turns.

FAQ

Truck and bus HVAC FAQ

Why is my truck A/C blowing warm air?

The most common causes are a refrigerant leak, a compressor or compressor clutch that is not engaging, a blocked or damaged condenser, or an electrical fault in the A/C controls. We check pressures and controls on site and find the actual fault before replacing anything.

Can you repair air conditioning on a bus or motor coach?

Yes. Buses and coaches have larger A/C systems than a truck, with bigger compressors, longer refrigerant lines and more evaporators and blowers. We work on them at your garage or wherever the bus is parked, and Ryon has a background on Prevost, MCI and Van Hool coaches.

Why is my truck heater blowing cold air?

The usual causes are low coolant or an air pocket in the system, a stuck heater control valve, a blocked or leaking heater core, or a blend door or control fault. We check them in that order on site, starting with the simplest and cheapest.

Is it safe to drive with the defrost not working?

It is not a good idea. A windshield that fogs or ices over is a visibility hazard, especially on a Nova Scotia winter morning. Get the defrost repaired before the unit goes back out.

Do you repair blower motors and ventilation fans?

Yes. Dead or noisy blower motors, failed resistors, burned connectors and ventilation fans that will not change speed are common repairs, and most can be done without taking the vehicle off the road for long.

Do you repair coolant heaters and block heaters?

Yes. We diagnose and repair fuel-fired coolant heaters and electric block heaters that help diesels start and keep cabs and coaches warm in cold weather.
