Whether used for extra income or as an office or home gym, new legislation is making Auxiliary Dwelling Units a realistic option for more homeowners than ever before. Control temperatures in the unit with a Ductless Mini-Split System from Air-Tro.

Leverage Home Ownership

If you’re like many homeowners, paying the mortgage on a Southern California property isn’t always easy. Renting out this space is a great way to add value to your home and defray mortgage costs immediately.

Work From Home? You Need an ADU with a Ductless Mini-Split System!

Who doesn’t want extra space? ADUs can also be used for home gyms or a remote office, or for anything else you would like. It has to be a semi-private space near (but not part of) your house. Garage conversions are perhaps the most common and least expensive way to add an ADU to your property. But, other options include assembling a prefabricated unit or having a contractor custom-build a unit on your lot.

Cost-Effective HVAC Is Essential

You’ll need to provide heating to qualify as an ADU. That’s where we come in: helping you select and install the right system to keep your occupants comfortable.

Look, nobody wants to spend more than they have to when adding an ADU or converting inside space to a home gym or office.

To keep it comfortable and cost-efficient you’ll want a separate thermostat, low-cost installation and energy efficiency. A ductless mini-split system provides it all and are perfect for ADUs.

They’re quiet and can be installed in a day or two, keeping labor costs down. Most ADUs rely on the main house utilities. But, the high efficiency of ductless systems means you won’t have to pay high electric bills to keep the space comfortable.
