When you have work done on your home, you literally have to live with the result. So, when the time comes to install, repair, replace or add a system to your home, take extra time and care in choosing your dealer. It could make a big difference.

Ten Tips

1. Check credentials. Before making your choice, call the Better Business Bureau to make sure the dealer is reputable. Also, find out if the dealer is a member of a local association such as the Air Conditioning Contractors of America. This, in itself, is some indication of reliability.

2. The dealer should be affiliated with a nationally known manufacturer. The reason: many dealers take advantage of factory training to help you determine your comfort needs. As a result, when they make recommendations, you can be more assured they have selected the right system for your home. They are also trained in installation and service.

3. Ask for references. Former customers are an excellent source of information. Call these individuals and ask if they were pleased with the dealer's work.

4. Expect an on-site evaluation visit. A good dealer should take a personal, thorough look at your home, evaluate your overall comfort needs and recommend the best system for you. Beware of a dealer that simply takes information over the phone.

5. Check local licenses. Depending on where you live, the dealer may have to comply with certain local or state regulations, so ask to see any applicable state and local licenses and insurance forms for liability and workmen's compensation.

6. Don't be afraid to ask questions. Ask for details about the firm's experience, its long-term stability and the expertise of its staff. This is especially true if you're adding air conditioning to an existing home where ductwork must be added. In this case, experience is a factor since it will take more thought, planning and know-how to get the job done.

7. Get a cost estimate. To make a fair comparison, be sure the bids you are looking at include the services you've requested and are based on the same size and efficiency equipment and the same quality of workmanship. Be wary of a dealer who offers unrealistically low prices; it may mean corners are being cut in crucial areas.

8. Inquire about equipment and labor warranties. Warranties vary according to manufacturers. Make sure the dealer 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.

9. Inquire about preventive maintenance service contracts. Many dealers offer service contracts that call for periodic maintenance of equipment and, if needed, repairs. The fee for such contracts is usually well worth it in terms of obtaining optimum efficiency and performance from your system.

10. Finally, insist on a written contract. Commit your agreement to writing and have the dealer sign it. Your home's indoor comfort is important. Don't gamble with it by selecting an air conditioning dealer by chance.
