Remodel HVAC in Jacksonville, FL
Adding a room, converting a garage or opening up a floor plan changes what your HVAC system has to do. Cool Cats checks whether your current system can handle the change and lays out your options to modify or replace it.
Remodels That Affect Your HVAC
- 🐾
Additions
More square footage means more cooling, and the existing ducts may not reach the new space.
- 🐾
Garage and bonus-room conversions
Spaces that were never conditioned now need to be.
- 🐾
Layout changes
Moving walls can strand a vent or return, or change how air moves through the house.
Can Your Current System Handle It?
Sometimes yes, sometimes no. A professional load calculation on the remodeled home tells us how much cooling it needs, and we compare that to what your current system delivers. Then we explain the result in plain English.
Your Options
- 🐾
Modify the ductwork
Extend, reroute or replace duct runs to serve the new layout.
- 🐾
Add a ductless mini-split
Condition the new space on its own, without touching the main system.
- 🐾
Replace the system
If the current system is undersized for the new home or near the end of its life, a replacement may make more sense. Replacement estimates are free, and every HVAC installation carries our two-year labor warranty.
Plan HVAC Early
The easiest time to deal with HVAC is before the walls and ceilings close up. Call us while you're planning, and we'll talk through the options and timing with you.
Frequently Asked Questions
Can my existing AC handle an addition?
It depends on the size of the addition and how much capacity your current system has to spare. A load calculation on the remodeled home answers it.
Should I extend my ducts or add a mini-split?
It depends on whether your system can carry the extra load and how practical it is to reach the new space with ductwork. We'll walk you through both.
If I replace my system during the remodel, is the estimate free?
Yes. Replacement estimates are free and include an inspection, home measurement, professional load calculation and multiple options.
