The business
Small shop. Senior tech. Real measurements.
Universal Air Systems has been serving homes and businesses across the GTA for over two decades. We stay deliberately small so that every install and every service call goes through a senior licensed technician — not a junior, not a dispatcher, not a commissioned salesperson.
We install equipment you own outright. We quote fixed prices in writing before any work begins. We diagnose with real measurements — gas pressure, combustion analysis, static pressure, refrigerant — not guesses. And we answer the phone ourselves, 24/7.

What we stand for
Four things we won't compromise on.
-
Honest scope, honest price.
Quotes are fixed and in writing. No scope creep on the invoice. No 'we found a few extra things' after the truck leaves.
-
Senior tech, every job.
You get the owner or a senior licensed technician — not an apprentice doing a training job on your house.
-
Same-day when it's urgent.
No-heat and no-cool calls get priority dispatch. Most GTA-core calls are handled door-to-door in 2–4 hours.
-
Measured, not guessed.
Every install sized with a real load calculation. Every repair diagnosed with real measurements — combustion, static pressure, airflow.
Open 24/7
Ready when you are.
Most GTA calls get same-day service. Call, text, or request a fixed quote — we'll come back with a real ETA.
