Right-sized cooling for ZIP 11801
Central AC Installation in Hicksville, NY
Hicksville is one of the most mixed housing markets we work in: post-war capes off Old Country Road, 1960s splits and colonials toward Jerusalem Avenue, and a steady stream of extensions, mother-daughter conversions, and full gut renovations. Each of those changes the cooling load, and a system sized to the original house will not keep up with the house that exists now.
So every Hicksville install starts with a Manual-J load calculation and a look at the duct system before equipment gets picked. Complete central AC installs run $5,800–$18,500 depending on tonnage, efficiency tier, and duct work, and financing is available.
Common problems — with real prices
Renovated or extended homes
New square footage almost always means new load. We recalculate and, where it makes sense, zone the system rather than forcing one thermostat to serve the whole house.
Two-family and mother-daughter layouts
Separate zones or separate systems, sized properly, so one unit isn't fighting two thermostats and two schedules.
Ductwork that can't carry the air
Older Hicksville trunks and flex runs are frequently undersized. Correcting airflow is usually cheaper than the extra ton people try to buy instead.
Heat-pump upgrade candidates
If your furnace is also near end of life, a cold-climate heat pump can cover cooling and most heating on one system. We price both paths honestly.
Homes with no ducts
Ductless mini-splits, one head per zone, installed without tearing up finished ceilings.
Second-generation replacements
Many Hicksville homes are replacing a mid-nineties system rather than adding a first one. That usually means reusing a duct system designed for different equipment, so we verify the existing static pressure and plenum fit at the estimate.
Local service notes for Hicksville
Hicksville coverage
ZIP 11801 — the streets off Old Country Road and Broadway, the postwar capes near the LIRR hub, and the blocks bordering Jericho and Plainview. Eight minutes from our Levittown shop.
Two-family conversions need honest load math
A legally converted two-family with separate thermostats is a different design job than a single-family cape, and treating it as one zone is how homeowners end up with a system that short-cycles upstairs and never satisfies downstairs. We calculate the load per conditioned zone and price zoning or a second system when the house actually needs it.
Electrical capacity and warranty
On a Hicksville install we check panel capacity for the new condenser circuit during the estimate, flag any electrical work it needs on the written quote, and register the manufacturer warranty after startup.
Adding cooling to a radiant-heat house
When the original heat is in the slab, a new central system needs its own duct plan from scratch, and sometimes ductless is the honest answer. We price both and explain the trade-off instead of forcing ducts into a house that was never built for them.

Hicksville questions, answered
$5,800–$18,500 installed. A typical changeout on serviceable ductwork lands around $7,500–$11,000; adding ductwork or zoning moves it higher. Every quote is itemized before equipment is ordered.
We determine it with a Manual-J load calculation based on your square footage, insulation, windows, and any additions — not a rule-of-thumb ton-per-500-square-feet guess.
Yes — we regularly design separate zones or separate systems so each unit controls its own comfort, sized correctly.
One day for most changeouts, two to three days when we're adding ductwork, zoning, or converting a home with no existing system.
If your heating equipment is also aging, yes — one system covers cooling and most of the heating season. We quote both so you can compare install cost and running cost.
