Appreciate your input on microchannel coils. I retired 5 years ago so I have limited exposure to microchannel. From what I have seen not real crazy about them. I do find they take extra time to...

As you may know I am now teaching HVAC/R at a trade college. The refrigeration encyclopedia generically talks about 10% in one chapter and then an undetermined % in another.

When I teach basic...

Okay guys we have a discussion going on one person says that the condensing unit is broken into thirds the first for de-superheating the second condensing and third for sub cooling. Another says it...

96% missed three I knew but second guessed myself. This is a really basic knowledge test can hardly predict or pronounce a person a PHD. Much of the test I learned by the time I was in the 9th grade.

What I am considering is a 20' X 70' lap pool 4' feet deep with a 15' section that is 12' deep for diving. It will be heated and have a seasonal cover. I want a year round pool for exercise for my...

Has anyone ever built their own pool. I am considering building a 75 foot concrete lap pool. Concrete above ground or at least partialy above ground. Considering running hyro heat in the walls of the...

I agree I have three bad disc in my neck, bad knees, lower back pain, bad ankle and a prosthetic in my right elbow. I went to a chiropractor for several decades, bought an inversion table 10 years...

I bought a franchise a few years back biggest mistake I ever made cost me most of a 1/4 million in just over a year till I fired them.

You are in the same situation buying a franchise as buying...

That's what I said it just took longer.:angel:

If Carolina is like Texas I do not think you will be able to acquire a license with out wrench time, unless you have a 4 yr. and even then I think you would still need so field time.

Now I would...

Much has been said on this thread that is incorrect, I worked as a sub for many years and when I had my own company I only used subs.

You do need your own insurance, medical and liability as well...

This appears fairly straightforward to me,you have an intermittent fan problem . Either the board is shutting down the fan after and hour or so or the fan motor is shutting down after an hour or so....

Yes go with two filters as far as I know no filter on the market is capable of moving 2000 CFM at design spec.

PM me and I will provide more info

Access doors/windows are required when installing a new coil in Texas. Codes differ from state to state and even municipalities within states.

Bill want to retire from service work and move to Killeen and teach, I am having the best time of my life and we need another instructor.

Actually in Texas you are required by TDLR to perform your work to current code requirements regardless of location. You are not required to upgrade the plenum to R-8 unless it is replaced and you do...

There are several answers for you, first AHS pays its contractors so poorly they cannot make a profit without finding additional work to be paid by the homeowner. So take the cash ( ANS has to pay...

Sent you a PM back last week have not heard back.

Curious as to what you consider oversized on the returns.

Yes it would be a reasonable application for a whole house dehumidifier and it can be installed independent of the existing systems very...

I agree with the two previous post, this detail is why company B was cheaper. It also raises the question what other short cut did they take; it has been my experience if you take one short cut you...

Need an instructor in Killeen, TX. to teach the trade at a trades college. You do not necessarily needed teaching experience, you do need the knowledge to teach our trade.

This is a challenging...

Having performed many energy audits and many air flow studies with a tru flo plate the answer is you need to perform the test with a wet coil. If you are not performing the test with a wet coil you...

First I agree with Bill, and I am one of those contractors that would build you the perfect system. However I am retired and have no interest in the work.

Next the ductwork is not rusted out it...

You do not say where in South Texas so that gives us a large area and climate to consider.

I agree with Udarrell that your system is very oversized, could be as much a 2 or three tons. My house...

I will explain and keep in mind we are talking about a two story home.

If the system is installed with multiple return and trickle bypass supply dampers the whole house will remain fresh without...

Simple reason for the price of two low end system and the cost to convert from one to two system he can have a top of the line zoned system installed. Not to mention he will have lower service &...

Udarrell is correct no way a competent person performed a load calc on a 3300 sq.ft. home built in 2004 and found that a 5-ton was required; unless you have a wall of Western facing windows.

Yeah I saw his post where he became upset and from his comments I am afraid he has passed.

Does anyone know Tipsrfines status, he has not had any activity here since 12-14 -14. I have tried to reach by IM and his e-mail address and no response.

I have students that are graduating soon that are and are willing to relocate.

give me a call or shoot me an e-mail

Hey Tech did you get my e-mail or IM

Can you contact me I have a student that is very talented been in the field for 5 years and takes classes from 5:30 to 10:00 M-Th looking for a better company. This guy is solid a hard worker and...

Do you have any positions for vo tech grads, we have several recent grads and more coming soon. We are in Killeen but our guys are looking around TX.

I do not know about the company you mentioned and I have a low opinion of Honeywell zone controls and the low end Carrier controls.

I did a great deal of zoning in Houston my home has a four zone...

What part of Houston are you in DrCool is in laporte and I do not think they come into Houston past the Southeast side.

I do agree that a single system on two story without zoning will not work....

Actually I believe NASCAR uses N2 for their pneumatic tools in the pits.

Yes it makes a great deal of sense I have done it numerous times. The trick is finding the appropriate contractor that can and will do the design and work properly.

Just saw your post in ARP!

I think it is a crime to rip out good metal duct and replace it with flex. Now finding a company that does either a rehab or new flex install properly is the trick. If flex is done correctly it is...

I would suspect the unit to be slightly overcharged, have the installer come back out and adjust charge to spec by SC.

I would suggest that you purchase HVAC-CALC and perform your own load calculation, it only cost $50.00 for your personal use. With it you can determine what your homes cooling load would have been...

I worked out of truck for most of 40 years, just cannot stand driving a van.

First if you do any install and even if you do a 1/2 ton truck is too light and will not hold up.
