Looks good, the only thing that stood out to me that is kinda an eye sore and hard to interpret is the links that say “Furnaces, Plumbing, Water Heaters etc etc.

The font and color is extremely...

I suggest a Y86 conversion kit if possible and be done with it if you factored out all other draft, or HX issues.

Call things fancy names that relate to what it is, capacitor is a dual starting device. They well google it and not be able to find it, come up with different lingo.

I've dealt with that a lot. Go...

I noticed the same thing happening with pro press that I've used on boiler installs. Went back a year or 2 later and started noticing very small leaks around joints.

Where do you guys put them on new installs? I put them right before the evap coil but I see many installers put them outside. What's the difference?

Yes I usually give the outdoor coil a quick hose down and waiting about 10 minutes after before getting any readings. Around here condensers sit in the elements for months before actually even being...

Lol ok. So if txv name plate subcooling is available charge to that, and fixed metering devices charge to super heat? I really use that chart until it becomes second nature understanding the numbers...

Thanks a lot man, to you how accurate is this chart I go off?

Ok thanks guys, I'm still trying to fully understand the entire method of troubleshooting problems that a lot of people in the field look past with super heat and sub cooling. Still kind of new in...

May be considered a dumb question for you seasoned A/c guys but what is other ways or more simple ways to determine my required SH and SC for a unit.

The way I pretty much learned was get target...

So I have the fieldpiece sc260 and I need a pipe temperature clamp, which ones are compatible with the meter and are actually accurate?

It gets better, had a call today for no cooling, just did the PM 2 days ago so what could it possibly be? I get inside and she says I don't know what's going on but it's actually heating the house. I...

How much do they usually cost? What's the best place to get them from amazon or elsewhere?

Well I certainly feel like it tested my knowledge, I'm still a rookie been doing it for 3 years and have so much more to learn and just studying for the test and taking it has shown me that. So I...

Flush the Evap coil, change the line set or flush it well and put in a TXV. Should be fine.

No very rare out here in NYC. Why?

Sorry if this isn't the right place for this but I recently took the A/C and Gas Heat tests and I'm just wondering how many of you are certified, was it worth it or just a complete waste. I know it's...

So even if I only use my gauges a few months out the year I should invest in them? I've heard nothing but good so I think it's something I'm going to be getting. Thanks for the input everyone.

"I just changed my filter and now my a/c doesn't work".
Did you put the door on right??

Thanks. I'm definitely going to consider it.

That's very true, if your able to get jobs done in a timely manner then flat rate pricing works best. My company does plumbing as well but when I go and change a flapper for $215 in 10 minutes the...

I'm no business owner just a technician that has the ability to make sales with out calling out a salesman from the company. What do you guys feel about flat rate pricing. I know I've lost a few jobs...

First meter was a Fluke but I've switched to field piece I actually plan on going back to a fluke don't really see much of a difference I just like the feel of the fluke lol.

I'm not sure how the online classes work but I attended Build a tech from Lennox about a year ago with 2 years experience and I learned a ton. I know they offer Virtual Build A Tech but the hands on...

I usually flush lines when switching from 22 to 410a and never had problems but Tuesday I'm actually changing a compressor and line set that takes 22 but the evap coil is compatible with 410a I'm...
