Simcoe County's same-day HVAC contractor.
District Air Systems is a family-owned Innisfil HVAC contractor covering every home mechanical need, heating, cooling, water heaters, indoor air quality, and gas, across Innisfil, Barrie, and Simcoe County.
An Innisfil-based HVAC company built by licensed tradespeople.
We're a locally-owned HVAC contractor based in Innisfil. Our technicians are TSSA-licensed gas technicians, our company is a member of the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), and every crew member is WSIB-covered, so you never have to worry about who is on your property.
Everything we do is designed around one goal: making the right recommendation for the home in front of us. Every installation starts with measuring the home, every repair is quoted flat-rate before work begins, and every follow-up call goes to a dispatcher who already knows your address.
We cover every side of the trade under one licensed roof, furnaces, boilers, air conditioning, cold-climate heat pumps, ductless mini-splits, water heaters, gas lines, HRVs, air purifiers, thermostats, duct cleaning, and light-commercial HVAC, so you get one accountable team on the job instead of a stack of subs.
Four things we won't compromise on.
Honest recommendations
We tell you when a repair beats a replacement, even when it's the smaller ticket for us.
Do it right
Sized to the home, permits pulled, inspections booked. Every install, every time.
Local by design
Family-owned, based in Innisfil. Local dispatchers who know your neighbourhood.
Stand behind our work
Two-year labour warranty on installations. If we did it, we own it.
Licensed, insured, and answerable.
We take licensing seriously because our customers' safety depends on it. Every gas job is performed under our TSSA licence, every installation is permitted with the appropriate municipality, and every crew member is covered under our WSIB and general-liability policies.
