MAXAIR Low-Velocity Hydronic Air Handler
See your exact payment → · How financing works
The MAXAIR LV is a low-velocity hydronic air handler for homes with conventional ductwork. Hot water from your boiler runs through a copper coil and the blower moves warm air through your existing ducts, with no burner, gas line or venting at the unit. Made in Ontario by AirMax Technologies, it heats from 48,393 to 122,103 BTU/h (at 180°F water) and accepts a cooling coil for central air. Standard installation by Bison Air is included in every price.
- ✓ Standard installation included across Toronto & GTA
- ✓ Works with your existing ductwork, rated at 0.5 in. static
- ✓ No gas line or venting at the air handler
- ✓ Cooling-coil ready: 1 to 3 tons, depending on model
- ✓ Financing available, with no upfront payment options

💡 Sized for your real water temperature. Air handler output is published at 180°F water, but modern condensing boilers run most efficiently at lower temperatures. Output drops as water temperature drops (see the table above), so we size the air handler against your boiler's design water temperature and your home's heat loss, not the 180°F number.

🔧 What Standard Installation Includes
- ✓ Air handler set in place (vertical or horizontal, as the space requires)
- ✓ Connected to your existing boiler heating loop and ductwork near the unit
- ✓ Return-air filter rack fitted
- ✓ Electrical connection to an existing 120 V circuit
- ✓ Thermostat connected and tested
- ✓ Startup, air purge, water flow and airflow check
- ✓ 1-year labour warranty and warranty registration
Quoted as extras when needed: a new boiler or water heater, a circulator pump if your system does not already have one, new piping runs to the boiler, ductwork or plenum changes, an air conditioner and cooling coil, and electrical upgrades. We check your boiler, piping and ductwork before the job, and every extra is quoted in writing before work starts.
No built-in pump: MAXAIR air handlers use a separate circulator with check valve on the boiler loop. An air handler needs a boiler, combi boiler or other hot-water source; it does not make heat on its own. Need a boiler too? See boiler installation and combi boiler installation.
🛡️ Warranty
- ✓ Manufacturer: 1 year parts and labour, plus an additional 12 months on parts, where applicable (AirMax Technologies)
- ✓ Labour: 1 year from Bison Air, included
Manufacturer terms: using the air handler for temporary heat during construction voids the warranty, and a clogged or missing filter may void it. Replace or clean the filter regularly.
