What kind of heating does a Dundas house have?
Dundas is about 8.1 km from Waterdown, and HVAC Waterdown makes the trip for furnace repairs, tune-ups, air conditioning work and heat pump installations. Tell us what the system is doing and a technician will come out, explain what they find in plain words and give you a written price before any work starts.

Learn moreQuestions from Dundas homeowners
Do you come to Dundas for maintenance, or only for breakdowns?
Both. Many Dundas households book a fall furnace tune-up and a spring air conditioning check so small problems are caught before the busy seasons. A tune-up includes cleaning, testing safety controls and checking the venting and condensate drain where there is one, and you get a record that supports the manufacturer's warranty. See furnace and AC maintenance or book through the contact page.
Where do carbon monoxide alarms need to go?
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. That covers most houses with a gas furnace, a gas water heater or a garage built onto the side. If an alarm sounds, get everyone outside, call the fire department from there and leave the gas appliances off until they have been checked. Test your alarms this week, replace any that are past the date on the back, and if you suspect a venting problem, book a furnace repair.
Is my house heated by natural gas or propane?
Waterdown is served by the regional natural gas utility, which runs and upgrades the gas system across the Hamilton area. Homes beyond the gas lines rely on other fuels, such as propane or wood. The furnace, its burner parts and its venting all differ with the fuel, so it matters when we order parts or size a replacement. Check your heating bill or look for a propane tank outside, then mention which fuel you have when you get in touch.
