Older homes
We check duct space, access, and airflow before recommending purifier equipment.


Annex whole-home air-purifier service for older ductwork, shared-wall living, pets, cooking odours, and indoor-air concerns in a distinctive urban home.
Annex Air Purifier Services
Four Seasons Air Control helps Annex homeowners and property managers choose purifier equipment that works with older layouts and limited mechanical space.
In a compact city property, the best option depends on more than the air-quality concern itself. We consider the mechanical space, how the home or suite is used, the current filter setup, and whether the equipment can be serviced without creating a burden for residents.
