Frequently Asked Questions About HVAC in Jacksonville

Get answers to common questions about hvac services in Jacksonville, Florida.

1What is the typical cost range for replacing a central AC unit in a Jacksonville home?

For a full system replacement in Jacksonville, homeowners can expect to pay between $5,000 and $12,000+, depending on the home's size, system efficiency (SEER rating), and brand. Florida's high humidity demands properly sized, efficient systems (16+ SEER is often recommended), and local factors like accessibility and existing ductwork condition can affect the final price. Always get multiple detailed estimates that include removal of the old unit, new refrigerant lines, and a thorough load calculation.

2When is the best time to schedule HVAC maintenance or replacement in Jacksonville?

The absolute best time is during our mild spring (February-April) or fall (October-November) seasons. Scheduling during these shoulder months ensures your system is fully serviced before the intense summer heat and humidity arrive, and you'll find greater technician availability and potentially better pricing. Waiting until summer often leads to emergency service calls, longer wait times, and higher costs due to peak demand.

3Are there any local Jacksonville or Florida regulations I should know about for HVAC work?

Yes. In Florida, all HVAC contractors must hold a state-certified license (either Certified Air Conditioning Contractor or Registered Air Conditioning Contractor) to perform work over $2,500. The City of Jacksonville also requires specific permits for system replacements and new installations, which a reputable contractor will pull. Furthermore, systems must be installed to comply with the Florida Building Code, which includes specific wind-load and hurricane strapping requirements for outdoor units.

4How do I choose a reliable HVAC company in the Jacksonville area?

First, verify their Florida state license is active and insured. Look for established local companies with strong reviews on multiple platforms and ask for references in your neighborhood. A trustworthy Jacksonville provider will perform a Manual J load calculation to correctly size your system for our climate, offer clear written estimates, and discuss options like UV lights for mold/mildew control, which is a common local concern due to our high humidity.

5Why does my Jacksonville home's AC system seem to run constantly in the summer, and is this normal?

During peak summer months with temperatures in the 90s and extreme humidity, it is normal for a properly sized system to run for long cycles to both cool the air and remove moisture. However, if it never shuts off or fails to maintain temperature, it could indicate an undersized unit, low refrigerant, dirty coils, or failing components. Given Jacksonville's climate, ensuring your system is efficient and well-maintained is critical to managing both comfort and energy bills.
