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?+

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.

Do you install ductless mini-splits for additions?+

We plan line-set routing to keep exterior equipment as unobtrusive as possible.
