The Truth About Heaters and AC Systems

Whether you are battling extreme winters, or in the heat of a desert, you need climate control systems to keep you comfortable and safe in your truck. However, when it comes to heaters and AC systems, what usually goes wrong on them, and how can you maintain them?

Recently we interviewed Pat Carroll, the Vice President of Sales for Red Dot.

If you live in a climate that often gets cold weather, you quite often rely on your heater to keep the temperature inside the truck at a comfortable level. However, sometimes your heater may fail. What is a typical reason for a heater malfunction?

Pat said it best when he said,

”Primarily, as long as the heater core is specified correctly for the application, the only other things to go wrong occasionally are the blower motors, which may wear out so you don’t get any air-flow through the system, or a water valve malfunctions which interrupts the flow of coolant into the heater core. ”

Nowadays, technology has advanced when it has come to heaters. Now trucks have no-idle auxiliary bunk heating systems. This is very important for several reasons. First off, it is important to give the drivers a good night’s sleep, because that makes it safer for everyone on the road. Also, this innovation of having heaters without the need to idle the truck is tremendously cutting back emissions, and the wear and tear of a vehicle.

However, heaters do wear out over time, and when that time comes, it can be overwhelming. In the replacement parts market, there are many brands of parts you can find. When it comes to off the shelf heater units though, what makes Red Dot’s products unique in terms of quality and performance?

Pat highlighted some important facts when he said,

“A product doesn’t go out of Red Dot without being fully designed, and validated… They are built to survive.”

By having these strict policies when it comes to the quality of parts they release, Red Dot releases only the top of the line quality parts they make.

Heaters can be lifesaving when it comes to cold climates, but what about when it is hot outside? That is when AC systems are crucial. However, AC systems do eventually wear out like everything else on a vehicle. What causes this wear?

At the time mark 6:19 Pat said,

“The number one cause of failure is due to refrigerant leaks. In today’s systems the compressor, which is the most expensive component in an air conditioning system, relies on oil returning to it, in conjunction with the refrigerant. Often times, people develop a slow leak in their system, and do not notice until their compressor fails.”

The easiest thing to do to prevent your compressor from failing is to do regular inspections of all the joints, and hoses to see if there are noticeable leaks that need repair. By doing this little maintenance, you will save you, and your fleet lots of money.

In fact, to help you, even more, Red Dot has developed new technology like ProTecht that can save you a failure. ProTecht is an advanced troubleshooting, and system protecting part. It has charge sensing technology that monitors the refrigerant levels. If your level gets low but is still working, you get a warning. This allows the operator to get to a service center before his system fails.

Above all, when you buy a part, you want to trust that you are getting the best part for your money and that you can rely on it to last. You get what you pay for. By going with cheaper products, often it can end up costing you far more in the long run because of more downtimes from failing parts. Going with higher quality HVAC systems and replacement parts will lower your overall cost of operation for fleets and owner/operators.
