Air
conditioning.
Central air, ductless and heat pump cooling across Westchester County.
Most AC calls start the same way: one hot July week and a system that cannot keep up.
Sometimes it is a failed part. Sometimes the equipment was never the right size for the house.
JSM works out which before anyone talks about replacing anything.
Where there is ductwork, central air off a furnace or air handler is usually the answer.
JSM fabricates and runs the duct itself, so a long run or a cramped attic is no reason to cut corners.
Where there are no ducts, which is most pre-war houses around Bronxville, ductless is the clean fix.
An outdoor unit, a wall head in each room that needs it, and only a small hole through the wall.
A heat pump does the same job and heats as well, so AC and heat can come from one system.
The boiler can stay as backup for the coldest nights.
Sizing decides whether any of it works. An oversized unit short-cycles and leaves the house damp.
An undersized one runs flat out on the hottest day and never catches up.
So the visit covers the rooms, the windows, the insulation and what the ducts can carry.
On commissioning the supply air is measured, not assumed, before the job is called finished.
From our base on New Rochelle Road in Bronxville to every town below.
Each page covers the houses, the drive and what we see there.
Gas, steam and high-efficiency boilers, replaced properly and piped so the next person can work on it.
02Furnaces, full HVAC systems, ducted and ductless heat pumps, sized for the house rather than the catalogue.
03Tank, tankless and indirect hot water, installed and serviced so the last shower is as hot as the first.
04Annual service and repair for boilers, furnaces, heat pumps and HVAC, so the failure happens on your terms.
