Common Car AC Heater Repair Issues and How to Fix Them

When your car’s air conditioning (AC) or heater isn’t working as it should, it can lead to uncomfortable drives, especially during extreme weather conditions. Here’s a guide to some of the most common car AC repair issues and how they can be fixed – all with mobile services brought right to your doorstep.

1. Not Blowing Warm Air

One of the most common issues with car heaters is when the system doesn’t blow warm air or blows only cold air. This can occur due to several reasons, such as low coolant levels, a broken heater core, or a malfunctioning thermostat. When coolant levels are low, it prevents the heater from absorbing enough heat from the engine to warm the air. A damaged heater core, which acts like a small radiator, can also prevent proper heating.

How We Fix It

Our Car Heater Repair service begins with a thorough inspection of the heater core, coolant levels, and thermostat. If coolant levels are low, we will top them up and inspect the system for any leaks. If the heater core is damaged, we offer heater core repair or replacement services. Additionally, we check the thermostat and replace it if needed to restore the heater’s ability to blow warm air effectively.

2. Heater Blows Cold Air

Sometimes, your car heater may blow cold air instead of warm air, even when the heater is on. This can happen due to issues with the heating system's blower motor, a malfunctioning thermostat, or problems with the HVAC control valve. If the blower motor is faulty, it may fail to push air through the system, or if the HVAC control valve is broken, it can block the flow of heated air into the cabin.

How We Fix It:

When you contact us for Car Heater Repair, we begin by inspecting the blower motor, HVAC control valve, and thermostat. If the blower motor is malfunctioning, we’ll replace or repair it. If the HVAC control valve is faulty, we replace it to restore proper airflow of warm air. We also inspect the thermostat and replace it if necessary to ensure your heater blows warm air.

3. Heater Smells Bad

A bad smell coming from your car heater is often caused by mold or bacteria buildup in the system, especially in the heater core or ventilation ducts. Moisture trapped in the system can cause these unpleasant odors. Another potential cause could be the accumulation of dirt or debris in the air filter.

How We Fix It:

Our Car Heater Repair service includes cleaning and disinfecting the entire heating system, focusing on the heater core and air ducts. We remove any debris from the air filter and sanitize the system to eliminate bad smells. If needed, we replace the air filter to ensure fresh, clean air is circulating through the vehicle.

4. Heater Core Leaks

The heater core can develop leaks over time due to corrosion, age, or damage. When this happens, you may notice a sweet-smelling coolant odor inside the cabin, or there may be puddles of coolant in the footwell area. Heater core leaks can lead to the complete failure of your car’s heating system, leaving you without warmth during cold weather.

How We Fix It:

Our skilled technicians clean the condenser and check for any blockages that may be restricting airflow. We also inspect the rest of the AC system to ensure optimal performance. A clean condenser improves the efficiency of your compressor, helping it last longer and reducing the likelihood of a breakdown.

5. Electrical Issues

Electrical problems, such as faulty wiring or a blown fuse, can cause the AC compressor to malfunction. These issues often result in the compressor not turning on, leaving you with no cool air.

How We Fix It:

When you choose our Car Heater Repair service, we carefully inspect the heater core for leaks and signs of corrosion. If a leak is found, we offer heater core replacement services to restore full functionality. Our technicians will also check for any other signs of coolant leakage and repair them to prevent further damage.

6. Heater Not Responding to Controls

If your heater isn’t responding to the temperature settings or turning on/off when it should, there may be an issue with the control system, such as the heater control valve, the blower switch, or the thermostat. A malfunction in these components can prevent the heater from operating correctly, leaving you with no control over your cabin temperature.

How We Fix It:

Our Car Heater Repair experts will inspect the control system, including the heater control valve, blower switch, and thermostat. We’ll repair or replace any faulty components, ensuring that you can control the temperature inside your car effectively. We’ll also check the system’s wiring and electrical connections to make sure everything is functioning as it should.
