One Room HVAC duct replacement
Russell

Hey. I’m new to forum. I live in Nashville a have a craftsman style home built in the early 1940’s. 

The HVAC duct that supplies the upstairs bedroom run through a bedroom downstairs and the size of the casing around it makes the the door only open half way. I have attached pictures. I want to switch the duct something rectangular and narrow and snug a duct against the wall so in can open up the door a reasonable Distance. I’m looking for some guidance as far as the parts go. I was thinking 4” x 12” rectangular duct would carry the load. I’d love to go smaller but....thank you for taking a look.

How Can I Get Air Conditioning Without Ducts?

 

n its simplest form (called a “mini-split”), a ductless unit works much like a standard air conditioner. There’s an outdoor unit, just like normal, and there’s an indoor unit. Except in the case of a split system, the indoor unit houses a full miniature air handler system. 

 

The unit draws warm home air in, which is then blown over refrigerant-cooled evaporator coils. Basically this means it doesn’t need ducts, because it’s processing the air right there in the room the unit is installed in.

 

This application can see whole-home use as well in the second type of split system, a “multi-split” system. In this setup there is a single outdoor unit and multiple indoor units installed throughout the home in order to provide complete home cooling. All with absolutely zero ducts at all.

Choosing the Right System for Your Home.

Depending on what kind of home you have, your options for cooling systems may be limited. For example, installing ductwork in a home built without it is much more difficult than installing a mini-split system. 

Though the two have a few energy-efficiency differences, if you’re concerned with the environment or want to save on energy bills, you have options. Remember that both new central air and mini-split systems are far more energy-efficient than window air-conditioning units.
