About this service
A replacement air conditioner has to match the home it cools. AC installation and replacement starts with a load calculation for the property, then selection of a central air system or ductless mini-split suited to that load, installation of the new equipment, and removal of the old unit.
What the work involves
- Load calculation based on square footage, insulation, windows and ceiling height
- Comparing central air and ductless mini-split options for the property
- Removing the old condenser, air handler or window equipment
- Installing the new indoor and outdoor units and refrigerant lines
- Charging, testing and setting up the thermostat controls

AC Installation & Replacement — common questions
What size AC does my home need?
Sizing is based on a load calculation — square footage, insulation, window area and orientation, and ceiling height — rather than a rule of thumb. An oversized unit cycles on and off and leaves humidity behind; an undersized unit runs constantly without reaching the set temperature. A technician measures these factors during the assessment.
How long does a central AC last in South Florida?
Commonly 10 to 15 years with regular maintenance. Year-round cooling, heat and coastal salt air shorten service life compared with cooler climates, so systems in Miami-Dade often reach replacement age sooner than the same equipment further north.
What are the signs a system should be replaced rather than repaired?
Frequent breakdowns, rising repair frequency as the system ages, uneven cooling between rooms, and a system that runs constantly without holding temperature are common signs. The assessment compares the repair path with replacement so the decision is based on the condition of your equipment.
