Hard water scale on the heat exchanger, a blocked inlet filter or a frozen condensate line in a Simcoe County winter can all shut it down. The technician reads the unit’s fault history, checks gas supply and venting, then explains the repair before starting. Service calls are $139.99 + HST for the first hour on weekdays and $199.99 + HST on weekends. ## Navien Tankless Water Heater Installation Replacing a hot water tank with a Navien [tankless](https://northwindhvacpro.ca/tankless-water-heater-installation/) heater frees up floor space and supplies hot water on demand. Installation needs the right gas line size, proper venting and a condensate drain, so North Wind HVAC starts with a free at-home consultation and quote, sized to the household’s hot water use. The customer picks the installation date. New installations carry a 2-year North Wind labour warranty, on top of the manufacturer warranty, which is typically longer when the unit is registered. ![Navien Tankless Water Heater Installation](https://northwindhvacpro.ca/wp-content/uploads/2026/11/navien-tankless-water-heater-installation.webp) Our Service Areas ## Navien Tankless Water Heater Repair in Barrie and Across the GTA - Barrie and Simcoe Area - Toronto - Aurora - Brampton - Collingwood - Etobicoke - Innisfil - Markham - Mississauga - Newmarket - Oakville - Orillia - Richmond Hill - Scarborough - Vaughan [See all North Wind HVAC service areas](https://northwindhvacpro.ca/service-area/) **Barrie:** 87 Goodwin Dr #5, Barrie, ON **Innisfil:** 2223 Willard Ave, Innisfil, ON L9S 2C1 ## Book Navien Service in Barrie & the GTA Call Simcoe (705) 828-4482, GTA (647) 558-5528, or the 24/7 emergency line 1 (877) 707-1615.
