    • Essential HVAC Kit
Review Image by Bob Sale Bob Sale
Do you enjoy lugging around a giant gauge set and losing precious ounces of Freon every time you hook up to a maintenance customer’s AC to check the charge? Neither do I. This kit doesn’t even need low loss fittings. They somehow made it so you screw it in and the moment it presses on the Schrader it seals perfectly. Links to the phone so you can walk around and do other stuff while you wait for the AC to stabilize. This kit does everything short of filling out the invoice for you and collecting payment. I pitty the fool who doesn’t get themselves this totally sweet charge kit! You can collect your SH/SC, pressures, and delta T all onto your phone with performance graphs to show your customer the health of their system and document the job in your CRM. I mean c’mon, guy! This is the ultimate upgrade to your service kit. I love using it every day and those bent condenser fins where you used to hang your gauge set also love it. ... show more

    • Does the job
This is a very conveniently sized set, and accurate enough to handle the job. Every piece uses batteries, so have some extras and a #1 Phillips screwdriver on hand. These do not have the ability to measure vacuum. If you intend to use this set as a manifold substitute, be sure to have a salad of fittings like valve core tools, a core depressor, brass caps with seals, and whatever other various bits and bobs. The only major negative is that the Fieldpiece app has a monthly fee, so it's like you pay all this money to buy good tools and then have to pay rent to the manufacturer to use them. There is a workaround though, as MeasureQuick has a free app that works well with these and various other wireless HVAC tools. The Fieldpiece app is very robust and has the ability to save equipment and other data by location, which is likely a handy option for professionals whose price gouging and rounding up to the nearest thousand means they can afford it. That is not me. I passed the EPA 608 Universal and bought equipment simply because it cost less than the markup of hiring a professional for one AC install. At present I only use the equipment to keep those vultures away from family and friends. ... show more
