Ductwork gets evaluated as part of the install, since a new system on old, undersized ducts underperforms.

Permits pulled, inspections scheduled, and manufacturer registration handled.

If you're dealing with an old system finally beyond economical repair, a home addition that needs its own conditioned zone, or a builder-grade unit that's never kept up with the house, you already know an oversized or undersized system installed without a real load calculation will short-cycle, run inefficiently, or never keep the house comfortable — for its entire lifespan.

Hvac Installation FAQ

How do you determine the right size system for my home?+

A Manual J load calculation accounts for square footage, insulation, window count and orientation, and local climate data.

Do I need a permit for a new HVAC installation?+

Skipping permits can create problems at resale or with insurance claims later.

Will my existing ductwork work with a new system?+

Sometimes yes, sometimes it needs modification — we evaluate this during the site visit rather than assuming either way.

How long does a typical installation take?+

Straightforward system swaps often complete in a day; ductwork modifications or new construction extend the timeline.

What's the real difference between single-stage and two-stage systems?+

We'll walk through the honest payback math for your specific situation.

Do you install ductless mini-splits for additions?+

Yes — they're often the practical choice when extending existing ductwork isn't feasible.
