1. do your research
2. find system online, even with shipping you will pay half of what a 'contract' or company will charge. (you have eliminated the second, third and possibility forth mark up).
3. Be your own contractor (the contractor most like will do nothing but manage the project, possibly off site too).
If the contract has to hire two or three more licensed techs, you can eliminated the contract (another middle man) and use the information from step one to insure the necessary steps are followed.
4. Hire two or three licensed HVAC techs (must provide state licence #). Some may have the nerve to attach a $200 to $300 per hour price ignore those.
The contractor about would probably pay them 10-20 cents on the dollar for the efforts.
5. Have system checked to verify it is up to code.
