As temperatures increase, many of us depend on our air conditioning units to help keep us cool. Whether you are in the market to purchase a new unit or just looking to repair or maintain what you currently have, the Better Business Bureau is here to provide some “cool” tips.

Remember, always research the company first at

If you are looking at purchasing a new unit:

Do your research on the product. If a company is recommending a certain brand or model of an AC unit, study the product information and ask questions about anything you don’t understand.

Work with an approved, authorized dealer. Once you’ve selected the company and product, be sure the installer is an approved, authorized dealer by the manufacturer.

Find out about warranties or guarantees. How long is the product under warranty or does it only cover certain parts? Is the work/labor performed by the installer guaranteed for a certain length of time?

If you are looking for maintenance or repair:

Know your brand and model. Before you start making calls, be sure to have your brand and model number handy. Some companies may not be able to perform maintenance or do repairs on your model.

Get multiple written estimates for repairs. A written estimate should include a description of what work will be done, materials that will be used and the price.

Know your maintenance history. Are you changing or cleaning your air filters on a regular basis? Is your thermostat working properly? When is the last time you had your air unit serviced?
