AC Repair and Cooling Service in Toronto
When your air conditioner is not keeping up, making an unusual sound, leaking water, or not turning on, Critical Heating & Cooling can help. We provide practical AC repair, cooling service, and maintenance for homes and light-commercial properties in Toronto and nearby areas.
As a full-service HVAC company, we work across the system, not just one part. We can assess the thermostat and controls, electrical components, indoor coil, outdoor unit, refrigerant-related symptoms, airflow, drain, and other connected equipment within our service scope. We explain what we find, what needs attention, and whether repair or another option makes sense.
Call (647) 961-6355 for cooling service. We are open 24 hours and serve Toronto and nearby areas. You can also email george@criticalhvacservices.com with the property location and a description of the problem.
Common cooling and AC calls we assess
Air conditioner not turning on or not cooling. Weak airflow or some rooms staying warm. AC running constantly or shutting off too soon. Warm air coming from the vents. Frozen coil, ice, or unusual frost. Water around the indoor unit or a condensate-drain concern. Outdoor unit not running, making noise, or vibrating. Thermostat, wiring, or control problems. Unusual smells or operating sounds. Seasonal AC inspection, cleaning, and maintenance. Cooling concerns in a home, rental, office, store, or other light-commercial space.
What to expect from a cooling service call
Tell us what the system is doing, when the problem started, and whether anything changed before the failure. If it is safe, check that the thermostat is set to cooling, the equipment has power, and the filter is not completely blocked. Do not bypass safety controls or keep operating equipment that appears unsafe.
We will assess the reported symptoms, identify practical next steps, and communicate clearly about the work. If a concern is outside our scope, we will say so rather than guess or recommend unnecessary work.

How this page differs from the Emergency HVAC page
This page is the dedicated cooling and AC resource for repair, service, and maintenance questions. The Emergency HVAC page is for urgent no-heat, no-cooling, and other time-sensitive HVAC breakdowns. If your AC has stopped working and you need urgent help, use the emergency page or call (647) 961-6355.
