Car A/C Recharge & Heating Repair in Calgary SE & SW

Your vehicle’s heating and air conditioning system does more than keep you comfortable—it also plays a big role in safe visibility through proper defrosting and dehumidifying, especially during Calgary winters and shoulder seasons. Modern climate control systems can manage driver and passenger temperatures separately (dual-zone and tri-zone), maintain steady cabin comfort in +30°C heat or -30°C cold, and direct airflow exactly where you need it—windshield, face vents, or floor.

At Heritage AutoPro, we provide A/C repair, heating repair, and climate control diagnostics in Calgary SE & SW for most makes and models, including imports and specialty vehicles—without inflated “specialty” pricing.

Signs Your A/C or Heating System Needs Attention

If you notice any of the following, it’s time for an inspection:

• A/C not cold or takes a long time to cool

• Heat weak, inconsistent, or only warm while driving

• Foggy windows or defrost not clearing the windshield quickly

• Airflow is low even with the fan on high

• Strange noises from the dash (clicking, rattling, squealing)

• Musty or “dirty sock” smell from vents

• Temperature changes on its own (blend door / actuator issues)

• A/C cycles on and off too frequently

• Visible refrigerant/oily residue near A/C lines or components

How Your Climate System Works (Simple Explanation)

Your comfort system has two sides:

A/C (cooling + dehumidifying): uses refrigerant and components like the compressor, condenser, expansion device, and evaporator to cool air and remove moisture.

Heating: uses engine coolant and components like the heater core, thermostat, and control doors inside the HVAC box to deliver warm air.

Air direction and fan speed are managed by electrical controls, switches, resistors/modules, motors, and actuators—especially in newer vehicles with automatic climate control.

What We Check During A/C & Heating Diagnostics

We don’t guess—we test. Depending on the symptoms, our inspection may include:

• Vent temperature testing and system performance checks

• Fan operation and blower motor tests

• Control head, actuator/blend door operation checks

• Refrigerant pressure readings (high/low side) where applicable

• Leak inspection (visual checks and leak detection methods as needed)

• Inspection of A/C components (compressor, condenser, lines, fittings)

• Heater performance checks (coolant level, thermostat operation, heater core flow)

• Cabin air filter condition and airflow restriction checks

You’ll get a clear explanation of what’s wrong, what’s urgent, and what can wait.

Preventative Maintenance Tips That Save Money

A few simple habits can prevent surprise failures:

• Replace the cabin air filter regularly (often yearly, or sooner if dusty/smoky conditions)

• Run your A/C for a few minutes every month, even in winter (helps keep seals lubricated)

• Book a seasonal inspection (spring and fall are ideal in Calgary)

• If airflow is weak, don’t wait—restricted airflow can strain the blower motor and reduce defrost performance
