Older east-end homes
We check duct paths, exterior vent options, mechanical space, and retrofit limits.


Fresh-air support for Leslieville homes with older walls, tight renovations, finished basements, compact ducts, and HRV or ERV equipment.
Leslieville Ventilator Services
Four Seasons Air Control helps Leslieville homeowners improve fresh-air exchange around older structures, attached homes, tight basements, and newer renovation work.
We review filters, core condition, fan operation, drains, exterior hoods, duct connections, controls, and whether airflow can be balanced without disturbing finished spaces.
