HVAC &
heat pumps.

Install it, service it,

Heat pumps have changed what is possible in an older Westchester house. A modern system heats and cools from the same equipment, runs on electricity, and in a house with no ductwork a ductless setup puts a head exactly where the comfort problem is without tearing the place apart. That is why the bedroom shots on this page exist: one wall unit, no ducts, and a room that finally holds temperature. Where there is ductwork, a furnace or a full ducted system is often still the right answer, and JSM fabricates and runs the duct itself rather than subbing it out. The thing that decides whether any of it works is sizing. Oversized equipment short-cycles, never dehumidifies properly, and wears itself out; undersized equipment runs flat out on the coldest night and cannot keep up. So the conversation covers the square footage, the windows, the insulation, what the existing ducts can actually carry, and whether you want to keep the boiler as backup on the coldest days, which for a lot of houses here is the sensible answer. On commissioning the system gets measured rather than assumed, which is what the infrared thermometer in these photographs is doing: confirming the supply temperature is genuinely where it should be before anybody calls the job finished.
