Common Questions
Frequently Asked Questions: AC Installation & Replacement
1How much does a new AC system cost?
A new AC system typically costs between $5,500 and $15,000+ depending on system size, SEER2 rating, and features. Hales AC offers free estimates and flexible financing to fit your budget. We also help you maximize available rebates and tax credits.
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. 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?
Most residential AC installations are completed in a single day (6-8 hours). More complex installations involving ductwork modifications or multi-zone systems may take 1-2 days.
4What SEER2 rating should I choose?
In Florida, the minimum SEER2 rating is 15. Many homeowners consider 16-20 SEER2 systems for stronger efficiency in our hot climate. We'll help you compare equipment options, operating costs, and budget before you choose.
