Capacity assessment
A straight answer on whether the existing system can carry the new square footage before you build.
A new room is easy to build and easy to make uncomfortable. The HVAC needs to change with it.
Adding a room or opening up a floor plan changes what the HVAC system has to do. We handle duct modifications, equipment relocations and added capacity for remodels and additions within about 60 miles of Old Town — including the honest answer on whether the existing system can carry the new space or a mini-split is the better solution.
Overview
Most remodel comfort complaints trace back to a system that was never asked whether it could handle the change. An addition tied into an already-maxed system leaves both the new room and the old ones short. A wall removed between two zones changes how air moves through the whole house. We assess what the existing equipment and ductwork can actually carry, then either modify the distribution, add capacity, or recommend a ductless mini-split for the new space when that is genuinely the cheaper and better answer.
When To Call
What's Included
A straight answer on whether the existing system can carry the new square footage before you build.
New runs, returns and registers, or rerouting ductwork that is in the way of the renovation.
Moving equipment for a renovation, or adding a mini-split when extending the ducted system is not the right call.
Our Process
What is being added or removed, and what the existing system is already doing.
Extend the existing system, add capacity, or use a ductless unit — whichever genuinely fits the job and budget.
Duct work staged so it happens while the walls are open, not after the drywall.
We check that the original rooms still perform, not just the new one.

Questions
Sometimes, but not automatically. It depends on the size of the addition and how much spare capacity the current system has. Tying a large addition into a system already at its limit leaves the whole house uncomfortable.
For a detached or hard-to-reach space, a mini-split is usually cheaper and performs better. For a room next to existing ductwork with capacity to spare, extending is often the better answer.
At the planning stage. Duct routing is dramatically cheaper to change before the walls are closed.
Yes. Relocations for decks, pools and extensions are a normal part of remodel work.
