Conversion of R-134A to R-1234YF

Posted on March 19, 2025 - 1News, Air Conditioning 101

Conversion from R134A to R1234YF

An Update on the Future of Refrigerant – R-134A to R-1234YF from RedDOT.

The conversion from R-134A to R-1234YF has everything to do with increasing concerns about the environmental impact of these refrigerants. Three decades ago, R-12 was the industry standard. It was found to cause a depletion of the ozone layer, so R-134a was adopted since it did not contribute to ozone depletion. This solved the problem…or so we thought.

Several years later, it was concluded that many man-made gases were contributing to global warming, and R-134a was one of those contributors. A search for a refrigerant that is both friendly to the ozone layer and doesn’t contribute to global warming was started. R-1234yf solves both of those problems.

The transition away from R-134a refrigerant continues to be a key focus for the heavy-duty vehicle industry as we work toward reducing greenhouse gas emissions. While R-134a remains approved for off-highway applications, its phase-out for newly manufactured vehicles is on the horizon. By 2028, all newly produced off-highway vehicles will no longer use R-134a, marking a significant shift in mobile HVAC systems.

Note – R134a and R1234yf are NOT interchangeable

The EPA originally approved R-1234yf for use in passenger cars at the end of 2020, and since then, it has fully replaced R-134a in that market. However, R-1234yf is not yet approved for Class 6, 7, and 8 trucks. The EPA currently has an application under review for its approval in these larger vehicle classes. Once approved, this transition will play a vital role in reducing the environmental impact of mobile HVAC systems. For context, R-134a has a Global Warming Potential (GWP) of 1,430, whereas R-1234yf has a GWP of only 4. Additionally, while R-134a remains in the atmosphere for around 13 years, R-1234yf breaks down in just 11 days, significantly reducing its environmental footprint.

The good news is that both refrigerants perform very similarly in mobile HVAC applications, but R-1234yf offers a clear environmental advantage.

What Technicians Need to Know

Newer systems have very small capacities and are much less prone to leakage. This means that technicians need to take care not to overcharge the system. Many OEMs recommend service only every three years. The days of an annual top-off are over.
Newer systems require newer equipment to service them. Refrigerant recovery machines must comply with the latest regulatory standards and are to be operated only by licensed technicians. These machines can detect which type of refrigerant is present. Refrigerant types are not to be mixed.
The usage of dyes and sealants is discouraged. Dyes and sealants are considered contaminants and will reduce the performance and longevity of the lubricant. Use refrigerant sniffers for leak detection and repair leaking equipment per SAE and EPA guidelines.
BG Frigi-Quiet® for R-1234f, PN 702, is not approved for use in HEV or EV vehicles. These vehicles require the use of lubricants that pass proprietary electrical insulation performance standards, which PN 702 does not possess.

This change in automotive refrigerant technology has been the talk of the industry for several years.
R-1234yf will be the industry standard for the foreseeable future. As the industry prepares for these regulatory changes, we encourage customers to stay informed and take advantage of resources like the Mobile Air Climate Systems Association (MACS), which offers a comprehensive certification program on its website.

SPRING HVAC Tech Tips from RedDOT

Posted on May 10, 2022 - Air Conditioning 101, Technical Tips

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.

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.

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.

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.

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.

ESPAR Airtronic Heaters – Preventative Maintenance

Posted on September 22, 2021 - ESPAR, ESPAR Preventative Maintenance, Heating

Preventative Maintenance For Espar Airtronic Heaters

It’s recommended that Espar Airtronic heaters receive a pre-season check-up to ensure the heaters are ready for a trouble-free cold weather season. Always use the recommended tools and follow the procedures as outlined in the manual while removing and reinstalling the heater components.

ESPAR Heater Tip – Regardless of the season, run the heater every month for a minimum period of 15 minutes. This will help the heater burn away any combustion residue in the burner chamber, prevents corrosion in the waterjacket and decay of “O” rings. It also ensures that fuel in the lines to the heater does not gel and solidify and that the heater will start reliably when the heating season arrives.

The heaters should be inspected and repaired by an Espar trained mechanic, as follows:
1. Before the initial operation, ensure that the heater is not being subjected to external loads by heavy objects being placed over it. This may cause damage to the heater parts and affect its normal operation. Ensure that sufficient clearances, as recommended in the heater manual, are being maintained around the heater, even while the vehicle is in operation.

2. Check the return air inlet port and the hot air outlet port for any blockages. Inspect the length of ducting for any damage and replace as necessary. Ensure all ducting connections are secure. Discourage heat sensitive materials from being placed too close to the heater, ducting components or hot air outlet ports.

3. Check all electrical connections from the heater to the batteries. Check for wear and abrasion along the length of the harnesses. Repair or replace the harness whenever the harness insulation is broken or damaged. Check the battery connections. Clean any corrosion at the terminals. Replace the battery terminals if the corrosion is severe. Check the fuse for corrosion and the correct rating.

4. Remove the glow pin and, if necessary, clean it. If the glow pin shows signs of dissimilar colour or distortions, replace it. Inspect the glow pin wires for damage and if necessary, replace it. Remember to clean the glow pin chamber and ensure the glow pin ventilation hole is clear of any obstructions, then replace the glow pin.

5. Regardless of its condition, remove and replace the glow pin screen every pre-season. Make sure that the new screen is installed correctly. Install the new screen.

6. Check the condition of the exhaust pipe. Look for any holes or breaks in the exhaust piping. Replace if necessary. Ensure the exhaust pipe is securely located and correctly routed.

7. Check the condition of the combustion air intake tube. Clear any blockages. If damaged, replace it. Ensure that the combustion air intake tube is securely located and correctly routed.

8. Ensure the mounting angle of the fuel pump is in between 15-35 degrees. An incorrectly mounted fuel pump may lead to excessive carbon issues. Check the fuel lines for possible leaks, loosened clamps, etc., inspect the filter on the suction side fuel pump filter, clean or replace it as necessary. Once the entire fuel system has been checked and any issues corrected, it is advisable to do a fuel quantity check.

9. If the fuel quantity result is above specification, then it will be a cause for excessive carbon issues and the fuel pump would need to be replaced. If the fuel quantity result is within specifications, but on the higher side, then any possible excessive carbon issues may be corrected by increasing the mounting angle of the fuel pump to the near vertical position. If the fuel quantity result is below specification, then it is recommended that the fuel pump be replaced, but only if the heater repeatedly flames out during operation.

10. If there are complaints about the heater smoking excessively during operation, then remove and check the condition of the burner. The burner should be light brown in colour. Clean any carbon buildup inside the burner tube. Check the inside of the heat exchanger and scrape out any loose carbon.

11. When reassembling the burner and the heat exchanger, use a new thermal insulator. Likewise, when reassembling the blower motor assembly use a new blower gasket.

12. Reassemble the heater and test operation. The heater should be bench tested for 15-20 minutes before returning the heater to the vehicle.

ESPAR Hydronic Heaters – Preventative Maintenance

Posted on September 21, 2021 - ESPAR, ESPAR Preventative Maintenance, Heating

Espar Hydronic heaters are integrated into the cooling system of the engine and work independently of the engine, thus offers pre-heating of the engine and the vehicle’s passenger compartment. The thermal energy gained is then distributed through the vehicle’s own heat exchanger as forced hot air which heats the interior of the vehicle via existing air vents. The engine is warmed up with the residual heat in the cooling water.

Pre-Season Preventative Maintenance For Hydronic Heaters

Before the cold weather arrives, it’s recommended that your Espar HYDRONIC heaters receive a preseason check to ensure the heater is clean, free running and ready for a trouble-free season. Please use the recommended tools and follow the procedures as outlined in the heater manual while removing and reinstalling the different heater components.The heaters should be inspected and repaired by an Espar trained Technician, as follows:

1. Check all electrical connections from the heater to the batteries. Check for wear and abrasion along the length of the harnesses. Repair or replace the harness whenever the harness insulation is broken or damaged. Check the battery connections. Clean any corrosion at the terminals. Replace the battery terminals if the corrosion is severe. Check the fuse for corrosion and the correct rating.

2. Check all clamps and hoses. Replace as required.

3. Check the condition of the exhaust system. Check for holes and breaks in the exhaust piping. Replace the exhaust as necessary.

4. Check the fuel pump filter ‐ clean or replace it as necessary. For heaters with external fuel pumps, ensure that the mounting angle of the fuel pump is in between 15‐35o. An incorrectly mounted fuel pump may lead to excessive carbon issues. Check the fuel lines for possible leaks, loose clamps, etc. Once the entire fuel system has been checked and issues, if any, are corrected, it is advisable to do a fuel quantity check.

5. Check and clear clogged weep holes on the side of the heater body. Look for any indication of coolant leakages. If leakage is suspected then remove the cover with water pump assembly and inspect and replace “O” rings on the water pump housing. Closely inspect the heater waterjacket for leakages and replace the “O” ring between waterjacket and heat exchanger. If the waterjacket is cracked, replace it.

6. Remove and replace the glow pin screen. Make sure that the new screen is installed correctly as outlined in the repair manual for the heater.

7. Remove and check the glow pin. If it shows signs of dissimilar colour or if the glow pin is in any way distorted, replace it.

8. The coolant pump should be removed and the impeller checked for damage. Any dirt or metal particles on the impeller magnet should be removed and the cavity in the pump should also be cleaned. Please Note: coolant pumps are not covered by warranty if the vehicle’s coolant system is excessively contaminated. Refer to Technical Circular 250.

9. Remove the flame tube and check the condition of the flame tube end. The flame tube should be light brown in colour with no excessive carbon at the end of the flame tube. Check for carbon build up on the burner “nose” at the cold end of the flame tube. Any carbon covering the air slots should be removed. Check the inside of the heat exchanger and scrape any loose carbon out from between the fins in the heat exchanger. Re‐install the flame tube replacing all gaskets.

10. Re‐assemble the heater and test operation. The heater should be bench tested for 15‐20 minutes before returning it to the vehicle.

Carbon buildup. Remove it to increase heater performance

Posted on September 13, 2021 - ESPAR, ESPAR Preventative Maintenance, Heating

Carbon buildup can decrease heater performance and reduce operator comfort.

In the event that the burner / flame tube and combustion chamber of the Airtronic D2 or D4 becomes restricted and the heater fails due to carbon/soot build up it may be possible to clean the burner without disassembling the heater by running the heater in high using Kerosene instead of Diesel.

To help identify when a burner has excessive carbon build up, Click here and follow the recommendations.

Since the replacement of a burner with carbon build up is not covered by warranty unless the carbon was caused by a defective heater or component this bulletin will assist in reducing the cost and time of cleaning a burner that has caused the heater to fail due to excessive carbon build up.

The excessive build‐up of carbon in the heater is not a result of normal operation of the heater. The build‐up of excessive carbon or soot in the burner / combustion chamber and flame tube as well as the inside of the heat exchanger is in most a symptom of an underlying problem which is the root cause. Therefore, it is very important to identify and correct the root cause so that the burner does not become restricted again. Please refer to the troubleshooting guide and fault code list to identify the problem. Also refer to the installation instructions to make sure the heater and accessories are installed according to the installation guidelines using the correct parts.

In some cases the carbon build up in the burner may be too severe and the burner would need to be replaced. Unless the root cause of the carbon build up is corrected the replacement or cleaning of the burner will not result in a permanent solution but only a temporary fix.

How to inspect an A/C Compressor

Posted on May 26, 2020 - 1News, Air Conditioning 101, Technical Tips

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.”
