Frequently asked AC installation questions
These answers are written for homeowners who need clear, honest AC installation and replacement guidance in Palm Beach County.
How much does AC installation cost?
AC installation cost depends on the size of the system, efficiency rating, equipment type, ductwork condition, home layout, electrical needs, access, code requirements, and installation complexity. A proper estimate is needed because every home and system is different.
How long does AC installation take?
Many residential AC installations can be completed in one day. More complex jobs can take longer if ductwork repairs, electrical updates, access issues, permitting requirements, or additional comfort corrections are needed.
What size AC system do I need?
The right AC size depends on square footage, insulation, windows, ceiling height, sun exposure, ductwork, airflow, humidity load, and how the home gains heat. Bigger is not always better because oversized systems can short cycle and leave the home humid.
When should I replace my AC instead of repairing it?
AC replacement may make sense if the system is older, inefficient, unreliable, leaking refrigerant, needing frequent repairs, struggling to cool, or facing a major repair that costs too much compared with the value of the equipment.
Do you install energy-efficient AC systems?
Yes. Koolray Heating and Air helps homeowners choose energy-efficient AC systems that are properly sized for Florida heat, humidity, comfort needs, and budget.
Can a new AC lower my electric bill?
A properly sized, efficient new AC system may lower energy use compared with an older or failing system. Actual savings depend on the home, ductwork, insulation, thermostat settings, equipment efficiency, runtime, and how the system is installed.
Should ductwork be checked before AC installation?
Yes. Ductwork should be checked before installing a new AC system. Leaking, restricted, damaged, undersized, or poorly connected ducts can reduce comfort and efficiency even when the equipment is brand new.
What should I ask before installing a new AC?
Ask about system sizing, equipment options, efficiency rating, duct condition, thermostat compatibility, installation scope, warranty coverage, maintenance needs, and whether the system is the right fit for your home.
Is the most expensive AC always the best choice?
No. The best AC system is the one that fits the home, ductwork, budget, comfort goals, humidity needs, and installation requirements. Proper sizing and installation quality matter just as much as the equipment brand or price.
What happens if my AC is oversized?
An oversized AC can cool too quickly without removing enough humidity. That can lead to short cycling, uneven comfort, clammy rooms, higher wear, and lower efficiency. Proper sizing is important in South Florida humidity.
What happens if my AC is undersized?
An undersized AC may run constantly, struggle to cool the home, increase electric bills, wear out faster, and leave rooms uncomfortable during hot weather. The system should match the home’s cooling load.
Do I need a new thermostat with a new AC?
Sometimes. A new thermostat may be recommended if the existing thermostat is outdated, incompatible, unreliable, or not matched to the new equipment. Thermostat setup is part of getting the system to operate correctly.
When does AC installation make more sense than repair?
AC repair may be the right choice when the system is newer, has been reliable, and the repair is reasonable. A capacitor, contactor, thermostat, drain line, or airflow repair may solve the issue without replacing the equipment.
AC installation may be the better long-term choice when the system is older, inefficient, unreliable, frequently breaking down, struggling to cool the home, leaking refrigerant, or needing a major repair. Koolray Heating and Air can explain both options clearly before you decide.
Signs repair may still make sense
- System is newer and usually reliable
- Repair is minor or moderate
- Cooling issue has a clear simple cause
- Drain line, thermostat, or electrical part failed
- System still cools well after repair
Signs replacement may be better
- System is older and unreliable
- Major component has failed
- Repair cost is high
- System keeps breaking down
- Electric bills keep climbing
- Home has comfort or humidity problems
