What's the best way to ensure that the central air conditioning system you choose is installed properly, and will provide the most efficient and reliable cooling for your home?
The pointers below can help you find the right hardware and the right technician to install your system, whether you're replacing an older air conditioner or installing one for the first time. The information comes from our own experts and from heating and cooling contractors we surveyed.

And while there's no one money-saving strategy that will work for everyone all the time, there are a number of simple steps you can take, as we show in Keeping costs down. In some cases, you may be able to cut back on air-conditioner use considerably without seriously inconveniencing your family.

GET THE RIGHT CONTRACTOR
Finding a trustworthy contractor to install and service an air-conditioning system matters the most. Here's how to choose:

Ask around. Seek referrals from neighbors, family, or business associates. It's wise to get price quotes from at least three contractors.

Check the background. Contractors who bid on your installation should show you proof of bonding and insurance, plus any required contractor's licenses. Check with your local Better Business Bureau and consumer affairs office for complaint records. It's a plus if technicians are certified by North American Technician Excellence (NATE), a trade organization, and have several years' experience.

Get specifics. Contractors who bid on your job should calculate required cooling capacity by using a recognized method like the Air Conditioning Contractors of America's Residential Load Calculation Manual, also called Manual J. An additional reference for assessing ductwork needs is Manual D.   Be leery of a contractor who bases estimates merely on house size or vague rules of thumb.

Expect maintenance. A service plan that combines regular inspections with discounts on repairs and a labor warranty is worth negotiating into the overall price. Prices for such service vary widely.
