• To help make the selection process easier, we have compiled the following check list:

1. Check credentials.
2. Before making your choice, call the Better Business Bureau to make sure the contractor is reputable.
3. The contractor should be affiliated with a nationally known manufacturer.
4. The reason: many contractors have been factory trained to help you determine your comfort needs. They are also specially trained in installation and service.
5. Ask for references.
6. Former customers are an excellent source of information. Call these individuals and ask if they were pleased with the contractor's work.
7. Expect an on-site evaluation visit.
8. A good contractor should take a personal, thorough look at your home to evaluate your overall comfort needs. Beware of a contractor that simply takes information over the phone and then recommends a system.
9. Check local licenses.
10. Depending on where you live, the contractor may have to comply with certain local or state regulations, so ask to see any applicable licenses and insurance forms for liability and workmen's compensation.
11. Don't be afraid to ask questions.
12. Ask for details about the firm's experience, its long-term stability and the expertise of its staff.
13. Get a cost estimate.
14. To make a fair comparison, be sure the bids you are looking at are based on the correct size, the same efficiency equipment and the same quality of workmanship. Be wary of a contractor who offers unrealistically low prices; it may mean corners are being cut in crucial areas.
15. Inquire about equipment and labor warranties.
16. Make sure the contractor explains the terms of your warranty and that you understand it. In addition, many manufacturers offer extended warranties, which you may be wise to investigate.
