Frequently Asked Questions: AC Installation & Replacement in Dunedin
1How much does a new AC system cost in Dunedin?
A new AC system in Dunedin 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 Dunedin 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 in Dunedin 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. We recommend 16-20 SEER2 for most Dunedin homes, as higher efficiency systems pay for themselves through energy savings within 5-7 years in our hot climate. We’ll help you find the sweet spot for your budget.
