HVAC Refrigeration Evacuation | Technical Refrigeration - Why is it necessary to evacuate a refrigeration system before charging it with refrigerant? Because all systems are designed to operate without moisture or non-condensable gas in the system. If your air conditioner or heat pump was installed without a proper evacuation the system it will not function as designed and will likely fail prematurely. (more…)
HVAC Technician Tools - I can remember when I first got out of HVAC school a few years back I wanted to know what kind of basic tools I needed to begin my work as an HVAC technician. Of course, I had lofty goals and wanted to rise to the top but my expectations at the time matched my skill level. That skill level was a lot of book knowledge and not a lot of field experience.
After all, admittedly there are many lights that do not turn on in the classroom that does turn on in the field after some experience. Stress can turn some light bulbs on while others turn on easily after you see something for real the first time instead of reading about it in a book. (more…)
Condenser Coil Repair - A crane is used here to lift a new condenser coil to a rooftop. The old condenser coil was leaking and could no longer be repaired. The process involved recovering all the refrigerant from the Trane rooftop unit.
The rooftop unit was then partially disassembled and the old coil cut out from the system taking great care and planning to ensure the new coil could be retrofitted to the old refrigeration piping system.
Good planning and skilled HVAC techs make the jobs go smoothly and make the replacement seem easy especially to the customer. (more…)
