A Fraser Valley team that designs and installs heating, cooling and hot water systems the way we’d want them in our own homes.

O2 HVAC and Mechanical Ltd is a heating, cooling and mechanical contractor serving the Fraser Valley. We started O2 because too many homeowners and builders were getting systems sized by guesswork, installed in a hurry and left without anyone to call when something went wrong.
Today we work across Abbotsford, Chilliwack and Mission, from Clearbrook and Auguston to Sardis, Promontory, Cedar Valley and Silverdale. We install, repair and service furnaces, heat pumps, air conditioning, ductless mini splits, tankless water heaters and complete mechanical rooms for homeowners, and we design full HVAC systems for new custom homes, multiplexes and wood-frame buildings. We also take on commercial and refrigeration work [O2 to confirm].

Every system starts with a room-by-room load calculation. Right-sized equipment is quieter, lasts longer and costs less to run.
You see exactly what you’re paying for: equipment, labour, permits, and any duct or panel work. No surprises on the final invoice.
We pull the electrical permits and Technical Safety BC gas permits, and we book the inspections. It protects your home, your insurance and your rebate.
Floors covered, old equipment hauled away, work areas left clean every day.
We’re open 24 hours, because furnaces tend to fail on the coldest night of the year.
A good heating and cooling system is more than good equipment. The ductwork, venting, controls and finishing touches decide how quietly, efficiently and safely it runs for the next 20 years, so we take care of all of them.
Furnace, heat pump and tankless water heater planned together, with clean venting, labelled lines and room to service everything later.
Mechanical room coverage on our Full Mechanical Room Upgrade package [O2 to confirm terms].
Used instead of flexible duct where it matters, for even airflow that lasts.
Vents and returns chosen to suit modern interiors.
They reduce fire risk in long dryer runs.
We keep up with FortisBC, BC Hydro and federal programs so you don’t have to. See our Rebates page for what’s available now.
