I am expanding my area in South Florida. I am adding 3 Districts with a target start date of Jan 31st. I need experienced HVAC/R Techs to run each. The position is a District Technician, salaried,...

This is a bit confusing. Lets take it in chunks:
- at this point, the unit was attempting to cycle off - the low pressure switch should have shut it down. Either the liquid solenoid was closed,...

Had the same problem when I started. Had a couple of tickets in high school. Got a job running service through the summer, and the company conveniently ran my driving record in the fall. I worked...

No. The different line lengths wont matter. I would remove any extra piping at all. You probably have a dozen double traps that are hampering oil return already. Ideally the line sets will be...

I bought a house with an attic unit, one switch. I "intended" to put one on the other end of the overflow pan - but never did. Squirrels found the drain line, and filled the slightly out of level...

A paint lid hammer ($2 or $3 bucks at Walmart) does well, without risking damage. I've seen techs use rollers too. like posted above, make sure you don't bunch up, that section will not expand all...

I really like the Makita 12 volt impact for panel work, nice and small, power for days...just get off the trigger after the first couple of taps going back in.

Dr. Martens. Black, so I can polish them (USMC thing). Keeps them looking fresh. After a couple of years, I put an insert in them. The Dr. will resole them for free (or so I have heard - havent...

Great information! I would rule out your non-condinsable, your discharge temp vs pressure is right on.

So the 2 areas I would focus on:
1) Solid column of liquid getting to the TXV (dryer most...

I agree.

I would recommend changing the filter/dryer as a good practice.
I would NEVER put 2 in a system. The system wont care, it will run the same. The problem can come in down the road. ...

Belt is probably loose side to side, and miss aligned. Correct the alignment first. The miss-alignment is waring the sides of the belt - making it too narrow. Depending how long its been that way,...

For a basic, straight cool, AC system you are close

Vapor line = Suction line = Low Pressure line - in the trade it is usually referred to as Suction.

Liquid line = Discharge line = High...

No problem. I hope others read this and it helps them. It is shocking how bad some of the resume are that I get.

I agree with Krzyd. Tailor the resume to the job. I cant stress that enough. What job are you applying for - that will tell you what to cut, or "one line". I would list your certifications all in...

Agree with both on #1 and #2's above. I would add use the black hoses, they are much better for holding a hard vacuum. And you have to change the oil - a micron gauge will prove that.

I get your point. I will talk to you on the phone, and you will have cleared the first round before I call. I have done this for many years, and, in my experience, I have saved a lot more time and...

We require a background check, and you're authorization for a credit check. We could care less about your credit score, but a full credit check shows all your address and "variations" on your name -...

We tried the micro-channels.

Keep it short. 1 page max.

Things I want to see:
- Total number of years in HVAC/R
- Quickly figure how long you stayed at each previous job
- How much experience you have in THIS...

I have been and I now manage in-house techs. It is a constant battle to teach former contractors to 100% everything while they are there. I want my contractors to fix what they are called to fix,...

We tested several from several manufactures in different applications (roof top package units, and self contained refrigeration condensers) about 2 years ago. None are still in service - they all...

What type of defrost, what is the schedule? Superheat is required information.

Reduced condenser airflow will definitely cause slow ice making. If there are other issues, they will be hard to see without proper airflow as fell. You need to correct the airflow first. Make...

Nope, just wanting to help anyone that works on equipment like ours.

Great temp fix! You bought time to plan on changing the unit for a bigger one. No permanent way to make that work. It will rot the coil, and you may have waist water reclaim issues with the EPA...

The space needs to have positive pressure, but not too much. Make sure you have some make up air (approx 10%).

You need to run on 1 stage, cycling 2nd stage as needed. If you can control 2...

Hello. I am a Service Manager for a large retail company. We use both in house, and outside service for HVAC (primarily commercial package), De-humidification, supermarket refrigeration (RACKS) and...
