SPRING HVAC Tech Tips from RedDOT

Spring HVAC Tech Tips to ensure your AC system and its components perform optimally. Spring has officially sprung and the shift from cold to warm weather can prove impactful to mobile HVAC systems. Following best practices will help to weather even the most extreme seasons and keep your AC systems operating optimally. Read on for some technical tips on maintaining system integrity.  
 

  1. Close your HVAC’s water valve 

During winter, many people will keep their water valves open as they use their heating system. An important part of the shifting weather is to ensure that your water valve is operational and closed. When left open, the system will emit warm air even when the A/C is turned on. 
 

  1. Check for refrigerant leaks 

Most HVAC systems haven’t had their A/C turned on for months because they’re just used for heat during the winter. If an A/C system sits idle for extended periods of time, it can lead to the system’s refrigerant leaking out of the face seal. To check for a refrigerant leak, look for traces of oil on the system’s fittings, or use an electronic leak detector and check the service ports and charge ports where the gauge set is attached. 

  1. Inspect compressor belts for wear and tear 

Since A/C compressor belts are made of rubber, with time and use they will begin to eventually wear and will need to be replaced. Be sure to check the belt for any cracks, abrasions or glazing that will indicate wear and tear. You should also check your compressor belt for proper tension because too much tension will put too much side load on the clutch bearings and cause a leak, whereas too little tension will cause the belt to slip and generate heat, burning off the belt or clutch. 

  1. Ensure proper airflow 

Air filters should be cleaned every time a vehicle undergoes an inspection to ensure proper airflow and the quality of air that an operator will be breathing. It’s also important for air inlets in the operator cab to remain free from obstructions. Air inlets are usually behind the driver’s seat and can be unintentionally covered up by the vehicle operator. If you put your lunch, dog, coat, etc. behind your seat, you may block the inlet and prevent your A/C from properly blowing air.

Auxiliary Heater – Underseat High Performance

This underseat high performance auxiliary heater ( 082210000 ) is ideal for applications that require a small footprint (13.70 L x 9.21 H x 9.21 W ) but demand high performance.  With 42,000 BTU’s, it provides significant heating to ensure optimum operator comfort.

Auxiliary heaters are an additional heating component installed in vehicles to provide supplementary heat. It serves as a backup to the main heating system and allows the engine to warm up faster in cold weather. Heat is then transferred via coolant that circulates through the vehicle’s heating system. The heater may be activated manually or automatically when the engine coolant temperature drops below a set level.

Auxiliary heaters are common in diesel vehicles since diesel engines can take longer to warm up in cold temperatures. The extra heat provided by the auxiliary heater allows the passenger cabin to reach a comfortable temperature faster when first starting the vehicle. Some auxiliary heaters have electric fans to help distribute the hot air through the vehicle’s ventilation system. More advanced designs integrate with the climate control system for fully automated operation.
Overall, auxiliary heaters are an effective way to supplement the main heating system and provide fast warm up times in cold weather. With an auxiliary heater, drivers don’t have to wait as long for the engine to warm up before getting heat inside the cabin.

Air Filtration & Pressurization

Air filtration and pressurization are key components of HVAC systems that help maintain indoor air quality by removing airborne contaminants using filters. Pressurization helps control the direction of airflow and prevent infiltration of outdoor pollutants.

We offer two different Air Filtration & Pressurization Solutions. Both systems continually supply fresh filtered air into the cab creating a positive pressure inside a properly sealed cab. This over-pressure pushes clean air out leaks in the positive pressure side of the system, rather than allowing contaminated air to enter. The indoor air quality is critical to providing a healthy and productive work environment and whether it’s agriculture, construction, mining or waste management, operators spend a great deal of time in the cab of their equipment. 

Cab pressurizers are highly effective at removing particulate as well as vapors and fumes. The filter element can also be customized to target specific contaminates present where your equipment is working. A differential pressure gauge or electronic pressure control system are available to measure the difference in pressure between the inside and outside of the cab

Cab Filtration Solutions

The system incorporates Enginaire’s proven air pre-cleaner, with a patented in-line filter to make a highly efficient pressurizer that ensures clean filtered air. The unit combines a pre-cleaner with our proven VLR air filter system to give you a very efficient self contained filter air pump. As air is drawn into the air conditioner, the components remove large dirt particles with the built in centrifugal pre-cleaner.

The air is then filtered and blown into the air conditioner intake duct with our self contained air pump. By having a positive pressure on the incoming air chamber, the air conditioner can do it’s job easier with less power required. Even when the air conditioner is not being used, the clean air from the ECP is blown into the cab creating a positive pressure. This prevents dirt from entering the cab through leaks in it’s doors and other spaces.

Enginaire’s Cabaire™ uses it’s own high pressure air pump not a fan to deliver a high volume of dual filtered air into your enclosure which then has a positive air pressure on the inside. When the enclosure has a positive pressure, dirt is forced out of the doors, windows, and other unsealed areas instead of being drawn into the enclosure. You stay clean, your electronics and other instruments stay clean, while you “breathe easy”.

Diagnosis and Troubleshooting A/C Systems

Troubleshooting A/C systems can be done easily, if the proper components and steps are followed. A/C system performance is achieved with many components working together to provide cab comfort for the driver and passengers. The item that receives the most attention is the Compressor. The compressor operates as the “pump” of the system, keeping the refrigerant circulating and increasing the refrigerant’s pressure.

All compressors have two sides: Suction and Discharge. The refrigerant is drawn into the compressor’s suction side as a cold-low pressure vapor and then is compressed, thus raising the refrigerant pressure and temperature. The high pressure-high temperature vapor refrigerant is then pumped out of the compressor’s discharge side to the condenser.
As the compressor moves the refrigerant through the system, the refrigerant oil also moves with the refrigerant.

AC System - Replacement HVAC Parts & Supplies - ATC I 1-800-295-4156


Why are compressors removed?

1) Loss of a refrigerant charge – Cold refrigerant entering the compressor on the suction side coming from the evaporator provides cooling to the compressor. With a loss of refrigerant, the compressor overheats. Also, with a loss of refrigerant, the oil is not returned back into the compressor and eventually the compressor will run dry. AC Compressors - Replacement HVAC Parts & Supplies - ATC 1-800-295-4156

2) Contamination – Particles found inside the system will cause internal damage to your system. These particles can cause blockage at the condenser, expansion valve or damage to the internal parts of your compressor. Contamination must be removed from the system by using the correct flushing procedures.

3) Misdiagnosis – Change the wrong part is a common procedure in repair A/C failures. The system must be properly diagnosed before changing parts and pieces.

What are the most common causes of compressor failures?

1) Low Refrigerant Charge AC Compressors - Replacement HVAC Parts & Supplies - ATC 1-800-295-4156
2) Leaks with the System
3) Contamination in the System
4) Lack of Lubrication
5) Clutch Failure due to System Failure
6) Blockage or Restriction within the system
7) Insufficient Condenser Cooling

What happens if a compressor continues to run under a low refrigerant charge?

1) Overheating of the compressor occurs. AC Compressor - HVAC Replacement parts & Supplies - ATC I 1-800-295-4156
2) Refrigerant oil circulation slows down and returns very little back to the compressor
3) Without proper lubricant and refrigerant charge, the compressor will “lock-up” and destroy the compressor.
4) The critical low charge point is reached when the system has 50% or less of the recommended refrigerant charge.
5) Disabled or Malfunctioning switches that allow the compressor to run in a low charge situation.

With mechanical reliability at all-time highs, heavy-duty A/C components rarely fail. In fact, components mainly fail because of the contaminated refrigerant oil and general lack of preventive maintenance. Proper maintenance increases operating time and saves money by identifying concerns before they become problems.

How to inspect an A/C Compressor

Take these steps to inspect an A/C compressor to ensure it really needs replacing before you pull it from a heavy-duty vehicle:

1. Is The Compressor Rotation Smooth?
With the vehicle off, turn the compressor shaft with a 14-mm socket. If you feel grinding or hanging as you rotate the shaft, it’s probably due to broken components within the compressor. If the rotation is smooth, move on to Step 2.

2. Is The Coil Getting More Than 11.5 Volts?
Take a reading with the engine running and the clutch engaged. If there’s insufficient voltage, get to work on that. Otherwise, move on to Step 3.

3. Is The Coil Resistance Between 2.8 And 4.4 Ohms?
Any resistance outside this range will prevent the clutch from engaging or will cause used circuits to open. If the answer is yes, continue to Step 4.

4. Is The Compressor Able To Produce 350 Psig Or More?
If not, leave the compressor where it is. The system may have a low refrigerant charge because of a leak that needs repair, or a high-side blockage that limits refrigerant flow to the compressor.

Tech Tips from Red Dot
” We see lots of compressors that are returned fully functional and therefore not warrantable.
Get the diagnosis right. Inspect an A/C compressor before you pull the component from the vehicle.”

How to troubleshoot your A/C Electrical system

Tech Tips from Red Dot

On any vehicle and virtually any A/C system, electrical problems are among the hardest to troubleshoot. If you suspect an electrical problem with the A/C system, here’s a two-stage inspection routine that virtually anyone can do with no special tools or skills:

1. Inspect Electrical Connections

As you perform a visual inspection under the hood (cab) and/or at the rooftop condenser, take a moment to check all electrical connections both visually and by feel. Make sure all leads and wires are properly supported and securely connected, and that there’s no corrosion or grime on the leads or connectors.

2. Check Electrical Current Flow and Device Functions

Perform the following steps to check the current flow and electrical device functions:

  • Turn on the ignition. 
  • Turn on the A/C system. This will power the thermostat and clutch. If it does not come on, use the A/C mode switch to check the leads to the switch. You should hear a “click” from the thermostat and hear the clutch drive plate “snap” against the clutch pulley. 
  • Check fuses. If all the connections are clean and tight and there’s still a failure, check the fuses in-cab as well as in-line.
  • Check A/C clutch engagement. Since you can’t see and may not hear the clutch engage, get out and look at the clutch. If it’s engaged, you will see that the drive plate is against the pulley and not slightly spaced from it. If you aren’t sure the clutch is engaged, look for the lead wire connector near the clutch. Break and close that connection. The clutch will disengage and engage again.
  • Test blower speed operation. Some systems have a common switch that turns on the air conditioner and powers the blower motor. Test blower speed operation by adjusting this or the separate blower control switch. Feeling the air flow from the ducts or note blower sound (speed) changes.
  • Inspect roof-mounted condensers. Don’t forget to inspect roof-mounted condensers and A/C units for dirt and debris. Be sure the condenser fan(s) are working properly and all parts and electrical connections are securely fastened. The roof-mounted condenser fans may come on when the system is turned on. Like the thermostat and most clutches, the normal on-off cycling action cannot be observed until the engine is running with the A/C system on.
Once your visual inspection is complete, talk to a qualified A/C technician about what you found. Your troubleshooting efforts will be rewarded with a speedier repair and perhaps a lower repair bill.

Quick Heater Service Tip from Reddot
  • When the status is “heater fan doesn’t work,” check the ground connection for rust, paint, grime, or some other obstruction at the terminus.
  • If the motor doesn’t have a ground wire, its mount serves as a ground connection. Make sure nothing impedes the mount’s ground path.
  • Use a multimeter to make sure you’re getting full voltage to the motor. Once you know the voltage is adequate, you can then look for worn brushes, dirty squirrel-cage fans, damaged fan blades, and other more typical motor problems.

The reduced diameter hose enables tighter turns (but not right angles) without concern for “kinks” which would compromise the hose and AC system.
AC Hose Repair using Aeroquip EZ Clip Fittings and Hose is a quick solution for the quick turn around needs and mobile technicians. Providing even greater flexibility, when the E-Z Clip fitting is lubricated with a slight amount of refrigerant oil before it’s inserted into the hose, the direction/index of the fitting can be changed by rotating the fitting in the hose. Once the refrigerant oil used has dried (1-2 hours) the fitting can no longer be turned or re-indexed.

Blower Motors by Make

Blower Motors and Wheels are integral parts in the delivery and circulation of air in your vehicles Air Conditioning system. An Electric DC motor is used to circulate warm and cool air inside the cabin and/or sleeper. The Blower Motor “blows” and circulates the warm air from the fins of the heater core or cools the air as it passes from the fins of the evaporator.
Without these components, the hot or cold air produced by your air conditioning system won’t circulate to reach your vehicle’s interior cabin and or sleeper. We offer solutions for Freightliner, International, Kenworth, Mack, Peterbilt, Sterling, Volvo and Western Star. Review the fast moving replacements by Brand below or the full listing of replacement Blowers here.
