Frequently Asked Questions: AC Installation & Replacement
1How much does a new AC system cost?
Installed cost depends on the home load calculation, matched equipment, efficiency, ducts, electrical and drainage work, permits, access, controls, commissioning, and approved scope. Hales AC documents the proposed equipment and installation in a written estimate. Current financing or incentive eligibility is confirmed separately under the applicable written terms.
2What size AC system does my home need?
AC system sizing depends on your home's square footage, insulation, window exposure, ductwork, and other factors. See our <a href="/ac-sizing-guide/">AC sizing guide</a> for Florida-specific tonnage charts and BTU calculations. Our technicians perform a Manual J load calculation to determine the exact size needed. An improperly sized system wastes energy and won't cool effectively.
3How long does AC installation take?
Installation timing depends on the approved equipment, site access, electrical and ductwork scope, permits, and any multi-zone work. Hales AC confirms the expected schedule in the written installation plan before work begins.
4What SEER2 rating should I choose?
The applicable minimum efficiency depends on the equipment type and current regional standards. Hales AC compares matched-system SEER2 ratings, installed scope, expected use, comfort priorities, and operating-cost estimates; no single efficiency tier or payback period fits every home.
