Upstairs unit too warm, downstairs too cool
When one boiler heats both floors, the zone serving the lower unit may be starved while the upper unit gets too much. Balancing valves, zone controls and circulator sizing are where a technician starts.

Problems that come with Andersonville’s two-flats and cottages.

Two furnaces, one chimney
When one unit’s furnace is upgraded to a high-efficiency model, the other furnace and the water heaters may be left in an oversized chimney. That can cause poor draft and condensation, and sometimes needs a liner.
Garden unit damp and stuffy
Lower and garden units in older two-flats can feel damp in summer. Proper cooling, a dehumidifier or a ventilation fix usually helps more than turning the AC colder.
Before you replace anything
Two-Flat Owners in Andersonville
If you own the whole building, think about the two units together. Replacing both furnaces or upgrading a shared boiler at the same time can simplify venting and keep both tenants or owners comfortable.
If you own one condo in a two- or three-flat, find out whether the heating equipment is shared or yours alone before scheduling work, and let the other owners know if the water or gas needs to be shut off.

Yes. Separate furnaces per unit are common, and a shared boiler can be split into two zones with their own thermostats. Which is better depends on the piping, the budget and whether the units are rented or owned.
Old masonry chimneys were sized for several appliances. When some of them move to side-wall venting, the remaining water heater or furnace may not draft properly in the larger flue. A liner sized to what’s left fixes that.
Mini splits cost less for a few rooms and can also heat. High-velocity systems cool a whole unit evenly through small vents. The right choice depends on how many rooms you want cooled and where equipment can go.
