What we do
Complete AC services for GTA homes
Whether you need air conditioning repair in Toronto, a new AC installation in Markham, or routine maintenance in Scarborough, our team is ready to help.
AC Repair
When your air conditioner stops working or isn't cooling properly, HVAC BOSS diagnoses the problem quickly and gets your system running again. We handle all makes and models.
AC Installation
Planning a new central air conditioning system? We assess your home's layout and cooling needs, recommend the right equipment, and install it properly — so it performs well from day one.
AC Replacement
Older systems lose efficiency and reliability over time. We'll help you understand when replacement makes more sense than repair, and guide you through choosing a modern, efficient system.
Maintenance & Tune-Ups
Annual AC maintenance keeps your system running efficiently, extends its lifespan, and helps prevent unexpected breakdowns during the hottest days of summer.
Emergency AC Service
Air conditioning emergencies don't follow a schedule. HVAC BOSS offers 24/7 emergency service for urgent cooling problems — because a broken AC in July can't wait.
AC Equipment Sales
We supply and install air conditioning equipment from most major brands. Our recommendations are based on your home's size, layout, and your comfort goals — not commission.
Fully equipped, always ready
We arrive prepared — every time
Our service van carries the tools, parts, and equipment needed to handle most AC repairs and installations on the first visit. No waiting for parts, no second trips.
