What to look for when choosing a contractor

The key to comfort with any home comfort system is a quality installation.

If a system is correctly sized, designed and installed, it will operate at peak efficiency and give you years of carefree comfort.

So, when the time comes to repair or replace a system, experts recommend you take extra time and care in choosing your contractor. It could make a big difference.

In some cases, you may already have a preference for a certain manufacturer of air conditioning systems based upon a favorable experience or that of a friend or neighbor. In that case, the Trane Home Comfort Institute says look for a contractor that sells and installs that particular brand.

Tell the contractor of any problems you're experiencing with your current system so that he can properly evaluate your needs. Also, look into the benefits of a total comfort system, including electronic air cleaner, humidifier and programmable thermostat.

To help make the selection process easier, the Trane Home Comfort Institute has compiled the following check list:

Check credentials.
Before making your choice, call the Better Business Bureau to make sure the contractor is reputable.

The contractor should be affiliated with a nationally known manufacturer.
The reason: many contractors have been factory trained to help you determine your comfort needs. They are also specially trained in installation and service. Don't be fooled by equipment that is named after the installers - their name is covering up the real brand name that may not be highly rated.

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


Expect an on-site evaluation visit.
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.

Check local licenses.
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.

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.  Reliable contractors are professional. Their people are prompt and courteous. How a company treats you now reflects how they will treat you if there is a problem. They should have an office or shop facility, and they should not be ashamed to have you visit them. An office or shop is an indication that the company has been in business and intends to remain in business.

Get a cost estimate.
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 or very low-end equipment is being used.

Inquire about equipment and labor warranties.
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.

Inquire about preventive maintenance service contracts.
Many contractors 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.

Finally, insist on a written contract.
Commit your agreement to writing and have the contractor sign it.
