Storms are not the only thing that lead to power outages — as temperatures continue to rise, the nation’s power grid is only put under more strain. Planning ahead and staying safe is key.

Liquid line restrictions cause the evaporator, compressor, and condenser to be starved of refrigerant, causing performance problems in refrigeration systems.

Locating the source of a refrigerant leak in a self-contained reach-in cooler or freezer and repairing it may be difficult, but technicians should always attempt to find the source.

Like any piece of machinery or machine component, air-conditioning coils work better, and last longer, when properly cared for.

Comprehensive troubleshooting can help technicians determine whether the compressor is working properly.

Working as an HVAC technician requires a lot of caution and attention to detail to do the job well and remain safe. It’s important to ensure HVAC techs remember a few key things going into any job.

An evaporator can be cold but inactive, causing warm refrigerated space temperatures.

While all the technical principles I learned from Rob Falke were valuable concepts, the most beneficial lessons I learned from him were about life.

The condenser is the most underrated component in an air conditioning or refrigeration system.
