HVAC, Heating & Cooling Repair Toronto

FAQ

We install and service all major brands including Carrier, Lennox, Trane, York, Rheem, and many others. We’ll help you select the right system for your needs and budget.

Most residential installations can be completed in 1-2 days depending on the system complexity. We’ll provide you with a specific timeline during your consultation.

We recommend professional maintenance twice yearly – in spring for your cooling system and fall for your heating system. Regular maintenance prevents breakdowns, extends equipment life, and maintains efficiency.

Even well-maintained HVAC systems can show signs of trouble over time. From reduced airflow to unusual noises or moisture near the unit, these issues can signal that your AC needs attention.
