Evergreen, plain-language guides to the questions Central Florida homeowners ask us most — repair or replace, sizing, ductwork, cost, and warranty — so you can decide with the facts, not the pressure. For seasonal tips and news, visit our blog.
Repair or Replace My AC?
Repair a system under about ten years old when the repair costs less than a third of replacement. Replace an older unit, one on R-22 refrigerant, or one facing a compressor or coil failure.
Read the answer LearnWhy Is One Room Hotter?
A single hot room is almost always an airflow problem, not a too-small AC. The usual causes are a leaking duct run, a weak return, or thin attic insulation. Airflow fixes solve it more often than new equipment.
Read the answer LearnHow Long Does Ductwork Last?
Flexible ductwork in a Florida attic typically lasts about 10 to 15 years before the joints and insulation break down; sheet-metal trunks last longer. Heat and humidity shorten that, so many homes need duct repair before the AC wears out.
Read the answer LearnWhat Size AC Do I Need?
The right size comes from a Manual J load calculation, not a rule of thumb. It weighs square footage, insulation, windows, and sun. In Florida an oversized unit cools before it dehumidifies.
Read the answer CompareAC Replacement Cost
AC replacement cost depends on system size, the efficiency tier you choose, your ductwork condition, and permits — not a flat number. The honest way to get your figure is a written, itemized estimate after an in-home load calculation.
Read the answer Learn / ActIs My AC Under Warranty?
Most AC manufacturers cover parts for five to ten years, often ten if the system was registered near installation. Labor is separate and shorter. Check the serial number against the manufacturer's records before paying for a covered part.

Manual J, SEER2, static pressure, float switch, heat strips — what each one means and why it matters in a Central Florida home.
