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.
