Something You May Want to Consider on Every Call

November 29, 2016

In this video, technician Jesse Claerbout covers how to prevent wire rubout on a residential air conditioning PM or service call easily.

Over time, crankcase heater and high-voltage wires can rub against the copper. These can cause all sorts of problems, including the nightmare scenario of an electric short blowing out the copper and leading to refrigerant loss.

On a normal maintenance call, we should check the wire location and look for the rubout potential. If there is rubout potential, we can insulate the copper line to prevent damage from wire rubouts. Of course, that doesn’t address wire rubouts that have already caused damage, but line insulation is a great preventative measure.

I have been doing this and teaching this to our techs for the past 25 years. We also make sure that none of the factory tubing in the unit can vibrate against the frame of the unit or even another tube in the unit. We call that “housekeeping”. It keeps our clients happy and reduces our callbacks dramatically.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this short podcast episode, Bryan talks about fire sprinklers and how to avoid setting them off on job sites.

Fire sprinklers have an element in the center that expands when exposed to heat (like a TXV sensing bulb) and breaks the glass. When the glass breaks, the fire sprinkler starts pouring out water. In some cases, fire sprinklers are linked to a larger fire suppression system in which several may go off at once, but most of the time, only a single fire sprinkler will go off if bumped or exposed to heat.

If you’re using torches or doing any form of hot work in a closet or other location with a fire sprinkler, make sure to keep torches away from the heat-sensitive bulb or at least cover the sprinkler with a wet rag (and follow your company’s guidelines). Blunt force is another possible issue, so we want to avoid hitting the sprinklers with lifts, ladders, or building materials like studs. Keep clearances in mind, and watch out for your colleagues.

You can get some specialty-built cages to protect the sprinklers, but awareness is one of the best ways to protect fire sprinklers. If possible, make sure signage is posted or that you alert other people in the area about the fire sprinklers.

If the fire sprinkler does go off, make sure you can quickly reach the person(s) who can access the fire shutoff or direct you to the fire shutoff. While fire sprinklers won’t pose much of a personal safety hazard, property damage is a major concern. Training and awareness are the keys to preventing property damage due to fire sprinklers.
