Older houses
We review replacement choices when old heating no longer keeps up.


Thoughtful heating installation for Annex homes and suites where the equipment must fit both the property and city living.
Annex Heating Installation
An Annex heating upgrade often needs to work within an older home's character, a renovation, or a compact mechanical area. We explain furnace, boiler, heat pump, air handler, replacement, and rental options with the property in mind.
Whether you own a semi, condo, rental, or restored house, we assess the available space, current equipment, and comfort needs before shaping an installation plan.
