Rooftop Unit Repair in Markham

We work on all major brands including Carrier, Lennox, Trane, Daikin, York, and Rheem. From small retail units along Highway 7 to large systems on industrial buildings in the Markham tech corridor, our team has the training and parts to get the job done.

We maintain 24/7 emergency availability with dedicated coverage for Markham and York Region. Our technicians are typically dispatched within the hour and arrive with fully stocked service vehicles so most repairs can be completed on the first visit.

Key indicators include uneven temperatures inside the building, unusual sounds such as rattling or grinding, a noticeable rise in energy costs, frequent on-off cycling, reduced airflow, and visible ice on the outdoor coils. Early diagnosis saves money and prevents larger failures.

Absolutely. We create customized preventive maintenance plans that include seasonal inspections, filter swaps, refrigerant pressure checks, electrical testing, and belt and bearing assessments. Scheduled care keeps your system reliable through Ontario's extreme seasons.

Generally, if a unit is older than 15 to 20 years, needs frequent service calls, or the cost of repair approaches half the price of a new unit, replacement is the smarter long-term choice. We provide clear assessments and upfront pricing to help you decide.

Yes. All technicians hold valid TSSA licences and carry full liability insurance. We adhere to all Ontario building codes and safety requirements for commercial and industrial HVAC systems.
