Have your entire HVAC system inspected at an Alliance Truck Parts location on a yearly basis to ensure its operating efficiently. Early detection is key; even small leaks or damaged components can spread harm to the entire system, adding up to expensive repair bills and increased downtime.

If you notice a leak, immediately take your truck in for an inspection at your nearest Alliance Truck Parts location. Do not use any leak fixing products — they are only a temporary fix and can actually increase your repair bills due to excess debris in the system.

A dirty or clogged air filter dramatically reduces the airflow into the cab and can cause bad odors. Check and replace your filter regularly to ensure it is clean. The best way to tell if your filter is in good condition is to remove any debris, then shine a light through it, and if you can see the light, the filter is probably clean.

Keeping your condenser free of debris ensures it maintains a perfect cooling temperature in your cab. Check and clean your condenser regularly, especially in the Fall and Winter when leaves and other materials build up on the fins. Be careful cleaning the fins; bending or breaking fragile condenser fins can cause problems throughout the entire HVAC system.

A faulty blower motor will reduce or even stop airflow to your cab decreasing the performance of your HVAC system. If you notice decreased airflow or hear a buzzing, grinding, or humming sound as your turn on your HVAC, take your truck in to an Alliance Truck Parts dealer for an immediate inspection. If left unchecked, a faulty blower motor will eventually lower the pressure of the freon running to your condenser, potentially damaging your A/C system.

TECH TALK: HVAC COMPONENT MAINTENANCE

Proper airflow is essential for getting the most efficient operation out of your HVAC system. Alliance Truck Parts blower motors quickly and quietly create even air flow across your cab. Each replacement blower motor is built with heavy-duty components for reliable heating and cooling.

Water and other contaminants can drastically reduce the life and performance of your A/C system, leading to unexpected downtime for repairs to multiple components. Alliance Truck Parts receiver driers are built to filter out these harmful elements and reduce moisture, prolonging the operating life of your entire A/C system.

Your A/C system’s heater core is necessary for delivering warm, comfortable air to your cabin even in the coldest conditions. Alliance Truck Parts heater core assemblies are built to resist damage from high pressure or road vibrations, ensuring quick heated air delivery every time.

Keeping your cab comfortable in the hottest weather requires a heavy-duty condenser that can quickly cool the air. Alliance Truck Parts condenser coils are built to ensure the most efficient heat exchange and best airflow so your cab cools down quickly and evenly every time.
