Do Field Piece meters take any sort of special battery?
It calls for a 9v NEDA 1604 type battery. Will a regular 9v battery work fine?
I got the Battery light signal and I have to change the...
Udarell I asked a while back on that same subject.
The problem was an overcharged system and a thermostat calling for a cool of 68 at night.
My tech friend told me that the ambient air...
A- 10" run is consuming approx. 350CFMs.
B- 10" run is consuming approx. 350CFMs.
B- 10" run is consuming approx. 350CFMs.
C- 6" run is consuming approx. 100CFMs.
D- 8" run is consuming approx....
One of my ex coworkers used the Rigid 18v Hammer drill. Its sturdy and fast. I would say its just about as good as Dewalt, but it is no Dewalt.
I buy only Dewalt. If I would buy any other drill it...
hey jason, not everyone on this site is a jerk.
Can you tell us the duct runs off of the supply side. Along with the R/A.
Most 3 ton systems are rated at 400CFM per ton. 1200CFMs in a 3 ton...
Petec, if your 3 ton worked fine then a 3.5 will offer the same.
I always oversize my systems by half a ton. Its worked for me, and I assure myself that the homeowner cannot complain of lack of...
My only question is how did you take off the gas meter. Here we can not take it off. PGE won't let us remove those.
Its fine how you have it. As far as appearance, like mentioned above you could have used a longer piece of conductor pipe and made the angle farther back.
Either way, the pipe looks to fit into each...
I would hire an asbestos abatement company. You do not want that stuff around your family. If disturbed, even by accident the asbestos fibers can remain in the air for hours or days.
You don't want...
I asked this question not to long ago. I want to know more about servicing a FAU, but I can't go through school now.
The best book that almost everyone recommended was "Air Conditioning and...
The termination for the dryer vent should be have a flapper door.
Here is an Example
Notice that it has a wire mesh grille, that...
The ductwrap will pass. Dryer Vents and Branch Wyes are insulated without a vapor barrier. Low humidity here in California.
I've never hung a furnace on a job, I'm sure it will hold but If you can...
I have been looking to buy a multimeter for a while now, but I'm trying to get married so I'm on a tight budget.
I've narrowed it down to one multimeter.
The Fieldpiece LT17
40-60$ is kind of generous for any appliance. I've heard to expect 8% to 9% savings per SEER point above 10.(standard)
But I haven't seen any technical data about this. What is the average savings...
I've set 5 roof top package units in the last 2 months. You do not need a roofer, a Wonderbar will pull back the shingles without ripping them. If some of the shingles rip on the edges he can replace...
What kind of fluke are you using, Im trying to find a fluke that won't empty my pocket completely.
Is it Fluke 16?
Not heat water, haha. I was using water as an example.
I was just wondering if reducing the tempature in the liquid line from 125F all the way to say 80F would make a difference when the...
I was reading up on how the liquid line contains refrigerant as a high pressure high tempature liquid. R-22 at 278 psig will condense at 125F. So if the liquid line leaving the condensing unit is...
a transformer costs around $7.00 dollars + tax.
Boy I would hate to have known that after making 3 service calls for a stupid transformer.
Are you using any zoning?
On the current job I am on,...
Janet he is right, I learned that the contactor is pulled down by a 24 volt A/C wire and makes a clicking noise.
It could be a tripped breaker, last unit I saw that happened to I called my tech...
I know I probably shouldn't be asking this kind of question, but I don't want to know everyone's wages.
Just an approximation of what an entry level to 2 year experienced service technician would...
Cool links, hehe.
Thanks for the info. I just wanted to make sure that the condenser really removed the heat from the refrigerant thus making it into a liquid again.
Its like an Evap Coil in...
Mary Ann maybe your breaker tripped and he just reset the damn thing. If he was there for just 15 minutes.
Was your thermostat not working before this? Did you fiddle with your thermostat and mess...
You said slow leak! You bastard you let it out. And your grateful, pokerface your a funny guy.
Just kidding. Get some R-22 and do the 10 second rule.
Works everytime I have...
pokerface, your going to get in trouble. The copper lines have nothing to do with heating at all. I can't charge systems because lack of knowledge and certification. You need to get an accurate...
I have a refrigeration and A/c book and I still have a question.
After the refrigerant passes over the Evap Coil it is in the state of a low pressure vapor (COLD!!!) It turns from a Low press....
Why would a contractor direct you away from high end equipment??
This sounds wrong already, as someone said already they probably don't have 14 seer available to them. Most contractors quote you a...
So closing registers won't improve airflow in other registers? Or are you talking only about 2 story homes.
I live in a one story home and keep the washer/dryer and walk in closet...
I also have a question. What it that grill doing in the return duct? Some sort of berimetric relief?
Nice install by the way. Mine aren't too pretty yet but next time I will shoot for something I...
At work the mobile modular office that is the sales office for the new construction homes, the heat pump wasn't cooling down the office. Since they couldn't bare the heat till tomorrow they had a...
I'm sure dhvac is experienced enough.
Im also curious as to your method though.
Do you measure the house and give a rough calc. Say a 1000 Sq ft home, quote him on a 2 1/2 ton?? Then after you...
From the description you dont like in California where its mostly Flexible Duct. If its metal ducts.
Get a Drill.
Cast Coat or Versagrip.
Its common sense with the...
Just for my own clarification I thought the split tempature, or as I seen others call it spread. Was supposed to be 18-22 degrees, my tech told me 20 is the bulls eye.
And like you said 78 degree...
Wow, I thought I got screwed when a side job went bad on me.
For $50.00 measley dollars you helped this guy out.
Do they pay you bananas where you work.
If the house is 2250 square feet. And...
I'm no service tech. But the house we just purchased has a fairly old unit. I would say 18 years old. The house has 6 sky lights, and 8-10 4'x6' windows facing the South-West end of the house, and...
Hello, Ct2. Actually I started with Beutler. I quit Beutler for that exact same reason. I worked out of the Antioch shop. Mainly livermore/dublin/pleasanton area. Beutler is a decent company and they...
Thanks for the great information. I just spoke to a friend of mine and he gave me the "Modern Refrigeration and AC" book but I'll pick up the book both of you guys recommended, sounds like its a good...
dhvac thanks for the advice.
But do you recommend any books??
I'm looking for a book with pretty pictures!!
What about this book?
You mentioned that its not getting cold enough and the condensation isn't really there, but are you sure that the system isn't undersized?
I don't do exact heat calcs, I mean I don't calculate the...
Well Hello, Im Diego and I don't post much but I read every once in a while. I'm trying to learn more about the service side of HVAC. I currently work for a company out of Northern...
