Coming from the pt of view of 30 years in the industry, Experience has its advantage and yes it takes a lot to get certified, keep your certification up.
If not kept up with they will remove you from the list. No references for future busines
But what the issue is as Carla is asking for a Co. to just install for them.
Many Company's want the whole deal because it takes a lot to Train, Certify and keep professional people.
Factory certification, overhead to send a tech to training requires a return commitment to the company. The benefits are on both sides of the road. not just the business.
Some require the certification to stay with the Technician to maintain continuity in industry.
As listed above many will not support, supply, or even talk to no certified individuals.
Dealer Protection, good relationships
And they want you to only sell their product line. its a win win for both sides
I have seen many company's come to town with management personnel and acquire installers locally to perform the install, then their techs setup, program, test, hand off the package.
It does not take more than laborers to install most products today. Just good oversight
We sub out most of our labor to others and it works great.
Parts & Smarts is a known industry practice and should not be taken lightly.
Many small company's get a lot of work this way. Its a Circle that works
I guess there is a lot of fear and perspective in this idea of loosing to the others to install.
