We run a Manual J load calculation before recommending equipment size, not just matching your old unit's tonnage.

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

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?+

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

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

In most jurisdictions, yes — we handle the permit application and schedule required inspections as part of the job.

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.
