What Criteria should I use in selecting an HVAC system
Interview as many local contractors as you can, and ask them to come to your home to perform a system inspection and give you a quotation. To narrow down you pool of potential contractors, use the following per-qualifications:

See if the company has been in business long enough to have adequate experience.
Get proof that the company is properly licensed and adequately insured.
Make sure the company is going to visually inspect all of the air ducts and related system components.
Avoid advertisements for “$99 whole house specials” and other sales gimmicks.
