When most of us think about tools of the trade, a few main ones come to mind: manifold, multimeter, vacuum pumps, recovery machines… the list goes on. One that may NOT come up nearly as often as it probably should is the thermal imaging camera.  A few symposiums ago, Bill Spohn and Eric “Elk” Kaiser […]

Evaporator coil leaks are a fact of life in the industry. (We could have a long and lively discussion about how evap coils aren’t made like they used to be, but that’s for another day.) When you have an evaporator leak on a system, you’ll have two choices to fix the problem: replace the coil […]

In the furnace sequence of operation, the ignition sequence happens after the safeties have been checked, the inducer fan comes on, and the pressure switch closes. The ignition sequence begins with the ignitor. This part provides the heat needed for combustion (remember: a fire needs heat, oxygen, and fuel), and the ignition process looks a […]

James Bowman talks to Bryan about leak sealant products, including RectorSeal's Leak Freeze product. James talks about how sealants work, what happens when they don't work, and how to be open-minded without being gullible. Leak sealants must not react adversely with the components inside a system (oil and refrigerant). Just as mineral oil caused some […]

In this episode, Bryan speaks with James Bowman from Rectorseal about hard start kits, PTCR devices, run capacitors, compressor overheating, and the Kick Start product. We also go pretty in-depth on potential relays and how they operate. Hard start kits are mechanical potential relays connected to a capacitor, and they aid in starting the compressor. […]
