When it comes to air conditioning, from the time that you make your first contact with us to your unit installation, our team is dedicated to making sure your installations goes as smoothly as possible.

Choosing The Right Size

A crucial first step is determining what size unit is appropriate for your home or business. You don’t want a unit that’s too small to meet your cooling needs, but on the other hand, you don’t want a unit that exceeds your needs, forcing you to overspend on installation and monthly utility bills.

Air conditioning units are measured in tons, which refers to the amount of heat they can remove from your home or business in an hour. A one-ton unit can remove 12,000 British thermal units (BTUs) in one hour, while a three-ton unit would remove 36,000 BTUs in the same amount of time.

Obviously, the larger your home or business, the more cooling power you will need. For example, a 1,600 square foot home would probably need a 2 ½ ton unit to provide adequate cooling.

It’s essential to remember, however, that there are other variables to consider in determining the size air conditioning unit that is right for you. For example, if you have a basement, this area tends to be cooler than rooms on the upper levels of your home. So you cannot depend on square footage alone to determine the right size unit for your property, but with our years of experience, the experts at Deljo can determine your needs with precision and advise you on the units available in that size. We’ll help you figure things out!


Once your cooling needs are determined, installation is the next step, and this must be done correctly to avoid wasting your time and money. Expert installation is especially crucial if your home has never had central AC. The right wiring and duct work must be installed and your unit securely mounted on a concrete pad.

Rest assured, the cooling experts from Deljo can handle every facet of this crucial job to your complete satisfaction. We’re accredited by the Better Business Bureau and an 11-year Angie’s List Super Service Award Winner.
