Tankless Water Heater Installation & Repair in the GTA
Tankless water heaters deliver unlimited hot water on demand, use 30 to 40% less energy than tank heaters, and last nearly twice as long. For the right household, tankless is a massive upgrade. Complete Air Solutions installs, repairs, and services every major tankless brand across the GTA.
Tankless installation is more involved than tank replacement because of higher gas line sizing requirements, venting needs, and electrical connections. Our TSSA-licensed technicians handle every detail, including permits and code compliance.
We install Navien, Rinnai, Rheem, Bosch, A.O. Smith, and other leading brands. Most homes can be converted to tankless in a single day.

Tankless Water Heaters FAQs
Answers to the most common questions.
How long do tankless water heaters last?
Tankless water heaters typically last 15 to 20 years or longer with proper maintenance, nearly twice as long as traditional tank heaters. Annual descaling is important for maximum lifespan.
Is tankless worth it compared to a tank?
If you value unlimited hot water, lower energy bills, and a longer lifespan, tankless is an excellent choice. Upfront cost is higher, but savings over 15 to 20 years usually justify the investment.
How much does a tankless water heater cost installed?
Professional tankless installation in the GTA typically ranges from $4,000 to $6,500 depending on the brand, size, gas line upgrades, and venting requirements. We provide detailed quotes with no hidden costs.
Do tankless heaters work for large families?
Yes. Properly sized tankless units (8 to 11+ GPM) can handle multiple simultaneous showers and appliances. For very large households we recommend cascade or dual-unit configurations.
How often should a tankless be descaled?
Annual descaling is recommended, especially in areas with hard water. GTA water is moderately hard, so yearly descaling keeps efficiency high and extends the life of the heat exchanger.
