How do I find and evaluate a contractor?

Evaluating a contractor takes a little brainwork. This is an important process, however, because choosing the right contractor can make the difference between getting the most comfort and efficiency for your money, or getting stuck with a system that doesn't meet your needs. Here are some tips on evaluating a contractor:

Ask the contractors you are considering how much experience they have in the HVAC business. Common sense says that more experience should translate into a better record for customer satisfaction.
Check to see their contractor's license. Contractors must have a license to receive the permits needed for the job. And, only licensed HVAC contractors can legally purchase the refrigeration needed for air conditioners and heat pumps.
Ask for references. Then, follow up by calling those people and asking them how satisfied they were with the contractor. Try to ask specific questions, about the contractor's timeliness, ability to follow through on start and finish times, etc.

Questions you may want to ask:

Will the contractor listen to your needs?
Is the contractor complying with state and local codes?
Has the contractor provided you with a list of professional, business and trade references?
Does the contractor have continuous formal training for their co-workers to assure YOU the best quality job?
Is the contractor in good standing with the Better Business Bureau?
If anything goes wrong during the installation, does the contractor have adequate insurance to cover your losses?
Will the contractor stand behind your installation?
Can the contractor service your new system in the future?
Will the contractor install your new system in a timely, professional manner?
Is the contractor financially responsible?
Does the contractor background screen all of its workers to assure your security and its own reliability?
Has the contractor provided you with a list of satisfied customers?
Does the contractor have a 24-hour service department?
