Licensed New-System Installation & Permitting
Properly Sized, Properly Permitted Installs

New System, Done Right: Hvac Installation in South Pasadena, CA

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?+

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.
