Frequently Asked Questions

Replacing an HVAC system in a typical home is a custom-priced project confirmed after an on-site evaluation. The biggest drivers are equipment size and efficiency rating because larger loads and higher SEER2 models require more materials and labor. Our team regularly installs systems in the Fernandina Beach area, and coastal humidity or older duct layouts can influence the final scope. A seasoned installer will price the whole job, not just the box, so your comfort and code needs are fully covered.

Key factors that change price:

  • Tonnage and efficiency (SEER2/HSPF2) selected
  • Ductwork repairs or modifications
  • Electrical, drain, pad, or line-set updates
  • Permits, city inspection coordination, and thermostat or IAQ add-ons
