Commercial Truck HVAC Maintenance

Driving a commercial truck can be very stressful, with a lot of long hours spent on the open road in all kinds of conditions. The commercial truck’s HVAC system is designed to help make those long hours more comfortable by maintaining a stable environment inside the cab. Of course, if the HVAC stops functioning, then the driver’s job can become much, much more difficult. Use the tips in this guide from Fyda Freightliner to better maintain your commercial truck’s HVAC system.

How To Tell If Your HVAC System Needs Maintenance

It’s fairly easy to figure out if your truck’s HVAC system is in need of maintenance without an inspection. Simply use your senses. Strange noises, unusual smells, and poor overall performance are all signs that your commercial truck’s HVAC system is in need of repair. Other things to look out for include leaks, stains, and low air pressure. If you notice any of these things, your next step should be to diagnose the source of the issue. 

Broken HVAC Causes

There are many reasons why a commercial truck’s HVAC system might not be working properly. Start by looking for leaks since they are so easy to identify. Simply look under your truck the next time you stop. If there aren’t any leaks, take a look at the compressor. This component pressurizes refrigerant and pushes it through the HVAC system. If the compressor becomes contaminated, it will have to work harder to keep your truck cool, which can lead to long-term damage. If the problem is that your HVAC system only seems to blow hot air, the issue might lie with the condenser. This component processes refrigerant gas, converting it back into a liquid and bleeding off the excess heat. Make sure that the condenser hasn’t become clogged. 

Maintenance Advice

The best way to keep your commercial truck’s HVAC system in good working order is to perform regular inspections and keep up with your maintenance schedule. This includes checking your hoses and fittings for possible leaks and “recharging” the refrigerant as needed.
