Name: AAA Pro HVAC
Telephone: +1-844-611-2875
Price range: $$

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.

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, which is exactly why hvac installation calls in San Marcos, TX get treated with urgency, not a next-available-Tuesday slot.

Before You Call: Hvac Installation Answers

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?+

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?+

We'll walk through the honest payback math for your specific situation.

Do you install ductless mini-splits for additions?+

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

How disruptive is installation day for the household?+

Ductwork modifications or new construction work naturally take longer, and we'll walk through the realistic timeline during the consultation.
