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 Santee, CA get treated with urgency, not a next-available-Tuesday slot.
