What Waterdown houses tend to need
Waterdown households can book us from Smithville for high-efficiency furnace service, repairs, replacements, central air and heat pumps. If your furnace vents through plastic pipes in the side wall, we check them, the condensate drain and the ventilation balance as part of the visit, and you approve a written price before anything is fitted.
We make the drive from Smithville to Waterdown for heating and cooling work of every kind, and a good share of it involves high-efficiency gas furnaces and the small parts that keep them running.
Condensing furnaces have their own habits
A high-efficiency furnace makes water as it burns gas, and that water drains through a small line to a floor drain or pump. If the line freezes or clogs, the furnace shuts itself off. The same thing happens when the plastic intake and exhaust pipes on the outside wall get buried by drifting snow. Clearing them by hand often brings the heat back. If it keeps happening, the venting may need to be raised or moved. Our side-wall venting guide walks through it.
Carbon monoxide alarms
The Ontario Fire Code requires a working carbon monoxide alarm next to each sleeping area in a home with a fuel-burning appliance, a fireplace or an attached garage. Test yours when you change the furnace filter.

My Waterdown furnace shut off after a snowfall. What should I check first?
Go outside and look at the two plastic pipes where the furnace vents through the wall. If snow or ice covers either one, clear it by hand, then switch the furnace off and on at the service switch. Also check that the condensate line is not frozen or kinked. If the furnace still will not start, or the vents keep icing, book a furnace repair visit.
Who supplies natural gas in Smithville?
Enbridge Gas provides natural gas service across the Township of West Lincoln, and Smithville is part of that. The utility handles the gas supply and the meter. The furnace, water heater and other appliances in the house are yours to look after. If you ever smell gas, leave the house first and call the gas utility's emergency line from outside. For appliance problems, such as a furnace that won't light or keeps shutting down, book a furnace repair.
We're building on a new lot in the area. Can we count on getting natural gas?
Not always, at least not yet. Enbridge Gas has run a non-binding expression of interest to confirm demand for new natural gas distribution service in the Grimsby-Lincoln-West Lincoln area, starting December 1, 2029. It is also looking at options to add capacity there. Non-binding means nothing is settled. Ask the utility about service to your lot before you choose equipment. If gas is uncertain, it's worth pricing a heat pump set-up that could pair with a furnace later. Start with our heat pumps page.
