This tech tip was written by Eric Kaiser from TruTech Tools. Thanks, Eric! Filling refrigerant recovery cylinders is a task HVACR technicians perform regularly, but figuring out how much refrigerant to safely put into a cylinder can still be confusing. The challenge almost always comes back to refrigerant density or specific gravity. Specific gravity, also […]

Depending on what segment of the business you are in and your location, you either work on pump-down solenoid systems all the time, or YOU HAVE NO CLUE what a liquid line solenoid is. A liquid line solenoid valve (LLSV) is just a valve that opens and closes; it has a magnetic coil. Depending on […]

Maintaining the correct vapor-liquid refrigerant balance is crucial for air conditioning and refrigeration system performance. Longer line sets hold more refrigerant, which increases the risk of liquid accumulating in the suction line or entering the compressor during off-cycles. Heat pumps are one common application that requires additional measures. Refrigerant flow reverses during heating, turning the […]

In today’s podcast, Bryan and Jesse talk about how technicians can have conversations about finances and money in the HVAC business. The first step for any successful business is to provide customers/clients with a product or service of value. However, there must be a balance between providing something of value to customers and providing excellent […]

Bryan talks with Jesse and Nathan about setting up dehumidification for residential equipment in general. They also discuss some of the required and recommended settings on an Ecobee thermostat. On typical single-stage residential equipment, dehumidification works based on CFM per ton. We control humidity by dropping the CFM across the indoor coil and extending runtime. […]

Ductless expert Jesse Claerbout talks about his best maintenance practices for ductless air conditioners and heat pumps. This episode is part 2 of the two-part series. (Listen to Part 1 HERE.) Ductless outdoor units tend to have clean condensing coils. The only real issues are grass clippings (and cottonwood, in some locations). which typically don't […]
