Call us at 631-333-1613 to schedule.
When You Need Central AC Replacement
You need central AC replacement when your system is twelve to fifteen years old and repairs are piling up. Other signs include the unit running constantly without cooling, rising energy bills, refrigerant leaks that keep coming back, or loud grinding or banging sounds. A system that is undersized for your home will short cycle and fail to remove humidity. In Deer Park, where summer humidity is high, that shows up as rooms that feel clammy. Replacing with a correctly sized system fixes both cooling and humidity. We check your ductwork and electrical to make sure they can handle the new unit.
Our Central AC Replacement Process
We assess your home and your existing system. We size the new equipment for your cooling load and match it to your ductwork. We recover refrigerant from the old unit, remove it, and dispose of it properly. We install the new outdoor unit and indoor unit or air handler, run refrigerant lines, and wire everything. All refrigerant work is EPA 608 certified. We run startup and test the system before we leave. You get a written estimate before any work begins. New installations include a warranty on the equipment.
Central AC Replacement Cost in Deer Park
The cost depends on the size of the system, the brand, and how complex the job is. Ductwork or electrical upgrades can add to the price. We give you a written estimate that covers everything before we start. No hidden fees. You approve the work before we begin.
