Heating and Cooling Older Windsor Homes

Radiators and boilers

Many older homes still heat with hot water radiators. They're comfortable but don't provide cooling.

Adding cooling

Ductless mini-splits add cooling without ducts, keeping walls and trim intact.

Drafts

Older windows and doors leak air. Weatherstripping and storm windows help comfort in both seasons.

Tall rooms

High ceilings put heat at the top of the room. Ceiling fans on low in winter push it back down.

Old venting

Older gas appliances and chimneys need regular checks for safe venting.

Upstairs heat

Upper floors in old homes often overheat in summer. A head upstairs helps.

Electrical

Older wiring may need upgrades before adding equipment.

Plan in stages

You don't have to change everything at once; start with the rooms that matter most.

More help

See ductless mini-splits.

Boiler care

Boilers last a long time, but they need yearly checks of pressure, relief valves, pumps and venting. Bleed radiators that stay cool at the top.

Insulation

Adding insulation to attics and walls, where possible, makes the biggest difference in old homes. Older walls may have little or none.

Window units

Window air conditioners are common in old homes but block light and leak air. Ductless heads are quieter and more efficient.

Heritage rules

Some heritage areas have rules about changes to the outside of a home. Check before placing outdoor units on a street-facing wall.

Safety first

Old gas appliances, chimneys and wiring all deserve a professional look before you add new equipment. Carbon monoxide alarms near bedrooms are essential.
