Who you're calling
An owner who answers the phone.
Universal Air Systems is owner-operated by Param Sidhu — BSc. engineer and certified HVAC technician. Every install and service call is personally quoted and executed. No call centres. No commissioned salespeople.
"If I wouldn't put it in my own home, I'm not installing it in yours. Most problems in this trade come from cutting the wrong corner — and I don't cut any."
- Every job personally quoted
- Fixed pricing before work starts
- Warranty in writing on every invoice
- Manufacturer warranty registered for you
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. Pick up the phone or drop your postal code — we'll call you back with a real ETA.
