24/7 · No After-Hours Charge
Call (647) 219-5661
Licensed technicians on call 24/7 across nine GTA cities — with no after-hours surcharge, same-day repairs, and next-day installations. A real person answers the phone.
From a furnace that won't fire on the coldest night to a condenser that died in the first heat wave — we cover heating, cooling, hot water, and air quality. One crew, one phone number.
Furnaces, boilers, heat pumps. When the cold snap hits, a licensed technician is dispatched the same day.
AC repair when the unit gives up mid-July. AC installation when it's time. Ductless systems and fan coils too.
Tank, tankless, repairs, replacements. No hot water in the morning is an emergency — we treat it that way.
HRVs, ERVs, humidifiers, UV. We tune the home so the family breathes properly through every season.
Your equipment doesn't sleep, your home doesn't pause, and our phones don't go to voicemail. Whenever it breaks — we move.

Three of the homeowners cited on the live Atassi Mechanical site — quoted on the service they actually had performed.
"Furnace went out overnight. They had a technician at the door first thing — same flat rate, no surprise after-hours charge. Honest crew."
"AC quit during the heat wave. Diagnosed and fixed the same day. The team explained the options without pressuring me toward replacement."
"Took the financing on a new AC — zero down, zero interest. Install was the next day. Professional from the first phone call."
