Hydronic Air Handler Installation Toronto

Hydronic air handler installation in Toronto and the GTA. A hydronic air handler (also called a fan coil) uses hot water from your boiler or combi boiler to heat air and send it through ducts. There is no gas furnace, and the same unit can carry a cooling coil for central air conditioning. We install Airmax (MAXAIR) high-velocity and low-velocity air handlers.

✓ Hydronic specialists: boilers are our main trade
✓ Airmax MAXAIR high-velocity and low-velocity models
✓ Heating and cooling: add an AC or heat pump coil
✓ TSSA-certified gas technicians, licensed and insured
✓ 1-year labour warranty on every installation

Adding Air Conditioning

A cooling coil sits on the air handler and connects to an outdoor condenser or heat pump, so one duct system delivers boiler heat in winter and cooling in summer. With a heat pump outdoor unit, the heat pump can also take part of the heating load. See air conditioner installation and heat pump installation.

Prefer no ductwork at all? Ductless heat pumps add cooling to radiator homes room by room. We install both and will tell you which fits.
