Written estimates cover equipment, labor, and any necessary duct modifications together.

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?+

A mismatch between new equipment and old ducts is a leading cause of underperformance.

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?+

Two-stage equipment runs at a lower capacity most of the time, improving comfort and efficiency, at a higher upfront cost.

Do you install ductless mini-splits for additions?+

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