If you want to do your own research as well as using the official industry contractor list, then make sure you ask all contractors the following questions:
Are you members of, or certified by, ASHRAE (the America Society of Heating, Refrigerating, and Air Conditioning Engineers) and NADCA (National Air Duct Cleaners Association)? If they are, then they are qualified with the correct knowledge of the Carrier HVAC industry.
Are you insured? For a contractor to be insured, he or she must have convinced the insurance companies that they are not a risk because they do a good job. Not to mention that if they do a poor job, then you can sue the insurance company if the contractor has no funds to pay for the damage. Make sure you also ask for a copy of his or her insurance certificate.
Are you registered? Some states require that Carrier HVAC contractors are licensed. Find our if your state has a License Board or some other department (such as the Department of Revenue) that registers HVAC Contractors.
Can you provide some referrals? Always check multiple references by making a simple phone call.
How long have you been in business? The longer, the better. Contractors who have been in business a long time (a) know what they are doing and (b) make fewer mistakes than new contractors.
How would you determine the size of the new HVAC unit? A good contractor will not perform this calculation immediately, instead asking for more details and ultimately, to see the area.
We would also suggest contacting your Better Business Bureau and asking them if anyone has filed a complaint about the contractor in question.
Of course, we recommend choosing from quality contractors by using an estimation service that has already vetted contractors – such as this one

HVAC requires minute considerations of things like temperature, relative humidity and pressure, detailed spatial and environmental calculations, and involves various mechanical and engineering processes. All this must be considered even before the installations are made and your own system must be personalised to suit the idiosyncrasies of your location, environment and set-up. Your selected contractor must understand this.
