How should a Marcellus central air unit be sized?

By the cooling load on the worksheet, not by the old unit or the square footage. Ask to see the figure.

Will my ducts work for central air?

Perhaps, with changes. Ask the contractor to check supply and return paths on each floor and say what they would alter.

Why does my house feel cold but damp after the AC runs?

That is a common sign of an oversized unit shutting off before it removes moisture. Ask for the load figure.

Which refrigerant will the new unit use?

Ask the contractor. Federal rules limit what manufacturers may sell from 2025, so write the refrigerant and model on your contract.

Marcellus situations that call for new central air

Upstairs rooms hold the heat If second-floor rooms are the last to cool, tell the contractor.
A furnace duct system is the plan Cooling air has to travel the same trunks, so check what they can carry.
Window units stacked in sills Several window units suggest the whole house wants cooling, and the worksheet sizes the answer.
Muggy rooms after a short run Air that feels cold and damp points at a unit too big for the house.

A short, sharp summer in Marcellus

Syracuse's 1991 to 2020 normals show 58.3 days a year at 80 degrees or more and only 6.8 at 90 or more. Cooling degree days pile up in June, July and August, 483 of the year's 570. For a house in Marcellus the cooling job is concentrated into a few hot weeks, and the unit has to earn its place in them.

Planning a new system?

Ask about it

NYSERDA says oversized systems run in shorter cycles and may fail to dehumidify, and it states this for heat pumps. The same logic applies to central air. Ask the contractor for the cooling load on its own line, so you can see whether the quoted size matches it.

Of village homes, 81.5 percent predate 1980, and so do 72.2 percent of town homes. That means attics and walls that were insulated, or not, to an older standard. Tell the contractor what you know about yours, and ask them to look, because the cooling load depends on it.

Can a 1950s duct system carry cold air

The median village home is from 1952 and the town median is 1963. Ask whether your ducts were drawn for heating only, because cold air behaves differently: it wants return paths and supply registers in different places. Ask, "What can my ducts carry?" and ask for the airflow figure to each floor.

A larger outdoor unit will not fix a trunk that cannot move the air. If the ducts are the limit, the quote should say what changes and what it costs, before you sign.

Refrigerant on the quote and the permit line

Since January 1, 2025, a federal rule has stopped the making or sale of new residential air conditioners with refrigerants rated at 700 or higher for global warming potential. That governs manufacturers, and it does not make an older unit wrong. Ask your contractor which refrigerant the new unit uses and keep the model number in your file.

Ask the village and the town codes office whether central air alone needs a permit at your address, and ask your contractor who files it.

Keep the model number, refrigerant name and permit answer on one page of your contract, and ask the contractor to confirm the final price in writing.
