Start Capacitors for HVAC Compressors - Start Capacitor with Potential Relay
Start Capacitors for HVAC Compressors - HVAC single-phase compressors always come hooked up to a run capacitor. This helps the compressor when it is running, however, very few HVAC compressors come with a start capacitor. Most HVAC technicians know HVAC compressors pull a lot of amps on startup. This large amperage draws on startup is referred to technically as locked rotor amps or inrush current. It can be as much as 40,000 watts or more of pure power to get an HVAC compressor started.

Chapter Three NEC and HVAC - Article 300 - Wiring Methods

Chapter Three NEC and HVAC - Chapter Three in the NEC covers Wiring Methods which includes how the wiring is supposed to run, the conduit for wiring, outlets, junctions, and switch points, and a host of other topics about the proper way to run wiring.

HVAC Technicians will be familiar with piping support as is required in the Mechanical Code and electricians must follow some of the same rules when running conduit and add support for the conduit. (more…)

Condenser Coil Repair | HVAC Refrigeration

New Condenser Coil Repair - HVAC Crane LiftCondenser 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…)
