In this video, Joshua Griffin answers a question on whether gauges should be connected on every HVAC service call. This is a clip from our live show that we have every Tuesday night at 8:30 PM Eastern standard time. Joshua had a special guest named Larry Mason, who is an expert in home renovations and the two discuss the ins and outs of whether gauges should be connected on every single service call. They also discuss the good and bad sales tactics used by many HVAC contractors.

I stopped hooking my gauges up on maintenance calls once I discovered the feature on the Fieldpiece blue tooth psychrometers that can measure BTU output. If theres no customer complaint about anything and my condenser coil is clean, static pressure is good, my btu output is good on my fieldpiece probes, line temps are good, my delta T is good, and my compressor amp draw is good there's no need to check pressures. If any of those readings are off then I'll hook up and see what's going on my with pressures.
If you put gauges on a system twice a year for routine maintenance and don't purge and equalize your hoses (which 90% of techs don't do) it's going to be low on refrigerant after a few years and you're going to be telling the customer they have a leak when in reality there is no leak and the cause of low refrigerant is the fault of the company that's been doing the maintenance and taking a little bit of refrigerant out every time they hook up. Or worse, you might contaminate the refrigerant and cause a problem that could have otherwise been avoided. Thats my opinion anyway.
Here we are not supposed to routinely use gauges, only if you suspect there is a fault or to perform a repair etc.
If your on cooling check up on 7 years old system and it’s existing customer still do you checking pressures or not?
I could do with some guages 😢
Great information Josh 🛠️🛠️
If it wasn't leaking the valve core may start leaking if you mess with it. I always felt the temperature of the lines and didn't use gauges unless unless needed.
I do not attach gauges unless I believe there might be an issue with the refrigeration circuit. Besides the small loss of refrigerant, my main concern is contaminating a system with air or grime in my gauges. I will measure the temp split, amp the compressor and measure my lineset temps and compare to what I would expect it to be, seems to be the least invasive way, imo
Non invasive diagnostics works great, I'm not connecting Guages to everything Service area Nepean??
