Learn moreHow these guides are written
Local, sourced and kept current
Every guide is written by Glenn Milburn, our hvac guides editor, and focuses on how HVAC systems behave in Jacksonville specifically: a long muggy season, attic ductwork, salt air near the coast and short winters. Figures such as replacement price ranges and JEA rebate amounts come from published sources and are presented as planning ranges, not quotes.
When a fact changes, such as a new JEA program window, the guide is updated and its date changes with it. If you read something that doesn't match your situation, call and ask. A dispatcher answers live around the clock.
