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

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.

Common Hvac Installation Questions in Longmont, CO

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?+

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?+

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