Heat gain and loss calcs


Tarheel, most architects will already have those qualifications. No, the problem lies when people use stuff like Punch Software to design a home, and then take the info into the city and have it signed off, without really having it reviewed by a certified architect.

Agreed. I thought I was making this point.

The real problem is WHY they are using those programs.
Hint: It has everything to do with the nature of the "eye contact from the person and company" they otherwise go to for the information.

Despite the general wonderfulness and unerring competence of everyone who may contribute here --most of the guys down in the basements scribbling on their clipboards and coming up with quotes-- are NOT really trusted by the homeowner.

They end up with "Trane guy said $7000 Rheem guy said $6800 and Bob down the street used ____" as the basis for a decision. It's a lousy way to do business.

I had a quote done by the company that installed our Lennox Sig. Series furnace that we won in 2005, for having the oldest furnace in the drawing (1937 installed Octopus), and one of their guys came out, to give us a quote for moving one vent in our bath during the remodel, and add a line to replace one we were taking out in our dining, during our still ongoing remodel.

They wanted $700 to install the duct work, which was three pieces of 5 foot duct, and that was it. The rest was all labor. I ended up doing the work myself for $40 in materials. Even when I had them do the last inspection on the unit in 2010, before the five year was up on it, they wanted to charge us $200 to do a complete inspection, compared to another company that is better than them, would do it for $125. So who do you think I went with.

My guy that I use, did a complete inspection for free, when we did the a/c install, which was actually better than the original company that did the install of the furnace, when they did the first inspection in 2007.

It is a numbers game, when it comes to hvac equipment, and majority of the companies out there, know that they can pull the wool over the eyes of 90% of the people, because they are uneducated in how the equipment works, and those 90% are willing to pay anything to just have their stuff work, vs. looking into how to do most maintenance their selves, and minor repairs like changing out a bad capacitor, repairing a lv control line from the outside unit to the furnace, or change out a thermostat.

Er, no.

Those 90% are unaware of any practical alternative to bending over and taking it in order to have their stuff work. This is the issue.

And to be clear this isn't about small part service work
It's about remodels, updates and new installs.

Its about what joe tin knocker has been able to convince the people who stumble across him his service should be worth to those who have then become his customer base.

The issue is about the others... and why.

That is why I only use the two same guys, when I have to have work done on my place. I trust them, they both do good jobs at the work they do, and their price cannot be beat.

That may be your opinion, but a lot has to do with the fact that you can shop easier for jobs through the Internet, and do your homework more, than Pre-Internet.

For example, I want to redo the main supply trunk and duct work in my basement. I could do it myself, have a shop fab up the supply ducts, purchase the fiberglass/foil boards and make my own supply duct, then figure out the trunk line calc's, which actually would not be hard, since everything is available at my fingertips.

Most people out there do not want to do anything, and want companies to do everything at the cheapest price, then complain when the system does not work as they expected, or blame the company 10-15 years later, if something goes wrong.
