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.

Waiting rarely saves money and often turns a same-day repair into a longer, more involved job.
