Air Conditioner Repair
GTA HVAC Pros troubleshoots central air systems, condensers, coils, thermostats, drains, airflow problems, and electrical faults before recommending the repair.
Furnace Repair
We inspect ignition, burners, flame sensors, limit switches, blowers, filters, venting symptoms, thermostat calls, and safety controls before quoting repair work.
HVAC Installation
A better install starts with equipment sizing, duct and airflow review, venting, electrical needs, thermostat planning, and a clean commissioning process.
Heat Pump Installation
We help homeowners compare cold-climate heat pumps, hybrid heating setups, outdoor placement, line routing, electrical needs, and backup heat strategy.
Ductwork and Ventilation
We review duct runs, returns, registers, static pressure symptoms, ventilation needs, and equipment airflow to improve comfort and system performance.
Thermostat Installation
We check wiring, common wire needs, staged heating or cooling, heat pump controls, humidifier connections, and system response before finishing setup.
Commercial HVAC
We help offices, retail units, clinics, studios, and property managers handle HVAC service with practical scheduling and clear scope.
Emergency HVAC Service
