What Affects the Cost of AC Replacement?

System Size (Tonnage)

Bigger homes need bigger systems. The right size depends on your square footage, ceiling height, insulation quality, and local climate. A professional load calculation is the only accurate way to determine the right size — never guess or go by the old unit’s size alone.

Under 1,000 sq ft: 1.5 to 2 Ton
1,000 to 1,500 sq ft: 2 to 2.5 Ton
1,500 to 2,000 sq ft: 3 Ton
2,000 to 2,500 sq ft: 3.5 to 4 Ton
2,500 sq ft and up: 4 to 5 Ton

Brand and Efficiency

In the Rio Grande Valley, we recommend Goodman and Daikin — both certified brands with strong warranty coverage. Daikin carries premium warranties up to 12 years on parts and 6 years on unit replacement. Goodman delivers reliable performance at a lower price point.

Ductwork Condition

If your existing ductwork is leaking, improperly sized, or needs replacement, that adds to the total cost. We inspect ductwork as part of every free assessment.

Installation Complexity

Standard replacements in existing homes are straightforward. Unusual access conditions, attic installs, or code upgrades can affect labor time and cost.

Repair vs Replace — How to Decide

A simple rule: if the repair cost is more than half the cost of a new system, or if your system is 10 or more years old, replacement usually makes more financial sense. Modern systems are significantly more efficient and can lower your monthly energy bills enough to offset the cost over time.

Financing Options

We offer flexible financing with rates from 8.99% APR on standard terms. Payments as low as $79.99 per month on qualifying systems. Same-day approval available.
