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.

Before You Call: Hvac Installation Answers

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

Matching an old unit's tonnage without recalculating is a common and costly mistake.

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?+

We give a realistic estimate during the consultation, not a generic promise.

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

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

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