There was a story that came out recently based on an ASHRAE study performed by David Yuill from the University of Nebraska. The study appeared to indicate that condenser coil cleanliness makes no difference on system performance and efficiency. Those of us who have worked in the field know that coil cleaning matters because most […]

John Pastorello from Refrigeration Technologies joins us to talk about testing oil and refrigerant for contamination and what each is good for.

What to do when your tools get wet

Today's tech tip is a video put out by my friend Brad Hicks from the HVAC in SC YouTube Channel. Thanks, Brad! Seal boots to prevent raccoon leaks. Ok, this has nothing to do with raccoons, but I like that photo. Whenever you are installing duct boxes (also called boots or cans) in an aftermarket […]

Mike Hardy from SpeedClean joins us to talk about how SpeedClean got started and why engineered solutions should be considered by all contractors

Eric and Bryan talk through some non-standard ways of thinking about filter driers and how they can be installed.

“Service factor” is an interesting motor rating that you will see on many motor data tags. It simply means how much additional “work” a motor can do or how much “load” it may be placed under for short periods of time without failure or overload. For example, the FLA or full load amps of the […]

There are a lot of ads and news articles clamining that homeowners are in trouble and the R22 is becoming illegal. Is that true?

There is a common belief in the trade that the higher the subcooling, the better the system efficiency because lower liquid line temperature means less flash gas. This statement is only partially true and can lead to some confusion among techs. Subcooling is a temperature decrease below the condensing temperature of the refrigerant that occurs […]
