Furnace and air conditioning service in Waterdown
Whether your house went up in the 1830s or last spring, we explain what your furnace or air conditioner is doing and give you a written price first.
From Griffin Survey to Waterdown South
Which kind of Waterdown house do you live in?
Waterdown was built in three waves, and each one left a different heating system in the basement. Knowing whether your house came from the old village, the post-war surveys or the new subdivisions tells the technician where to look first.
Griffin and McMonnies and Stock surveys, before 1945
The Griffin Survey and the McMonnies and Stock Survey grew from Ebenezer Griffin's 1830 village survey and were built up before the Second World War.
Many of these houses started on coal or wood, with hot-water radiators or a gravity furnace, then moved to oil and later to gas. Technicians often find aging boilers, converted ductwork and unlined masonry chimneys. When a newer appliance vents into one of those chimneys, condensation can damage the masonry from the inside. The technician looks at the boiler or furnace together with the chimney and tells you whether a liner or a different vent is needed. If you are planning a replacement, ask for that assessment first; see furnace installation and replacement.
Glenlea, Buchan Court and Renwood Park, 1970 to 1981
The Glenlea Survey around Nancy Crescent was registered in 1970, the Buchan Court Survey in 1975 and the Renwood Park Survey along Flanders Drive in 1981.
These houses were built with forced-air furnaces, many first fired by oil and later converted to natural gas. When the furnace is upgraded to high efficiency, the gas water heater can be left venting alone into a chimney far too big for it, which can cause backdrafting. The original ducts are also often undersized. The technician checks how the water heater drafts and measures the ducts before suggesting a furnace size. If your water heater sits alone in the old chimney, make sure a carbon monoxide alarm works near the bedrooms and book a venting check; see furnace repair.
Waterdown South and Waterdown Bay, 2010s on
Waterdown Bay and the other new subdivisions of Waterdown South have been built since the secondary plan received final approval in August 2012.
These houses typically have a high-efficiency condensing furnace vented through plastic pipe in a side wall, a heat-recovery ventilator and central air. The usual calls are a blocked or frozen condensate drain, side-wall vents buried after a snowfall, and an HRV that is out of balance or has a neglected filter. The technician clears the drain, checks the vent terminations and balances the HRV. Between visits, keep the vents outside clear of snow and look at the HRV filter each season; see furnace and AC maintenance.
Waterdown heating and cooling
Who fixes furnaces in Waterdown's old and new houses?
Most furnace calls here start the same way: a January morning, when the normal daily average sits around -4.7 °C, and a furnace that has been working hard for weeks. What the technician finds next depends on the house. In the Griffin Survey it may be a newer appliance venting into an old masonry chimney. In Renwood Park it is often the original ductwork. In Waterdown Bay it is more likely a frozen condensate drain or a side-wall vent under snow.

Where else do our technicians work?
Beyond Waterdown, we work across the rest of Flamborough and the towns around it.
Waterdown is part of Flamborough, so rural communities such as Carlisle, Freelton and Troy are close to home. We also visit Aldershot, Tyandaga and Brant Hills in Burlington, Pleasant Valley and Westdale near Dundas, Spring Valley and Mineral Springs in Ancaster, and houses in Hamilton, Milton, Oakville, Stoney Creek, Binbrook, Caledonia, Grimsby, Brantford, Smithville and Beamsville.
Questions
What do people in Waterdown usually ask?
Snow drifted against the side of the house and the furnace stopped. What should I do?
Newer high-efficiency furnaces, like the ones in most Waterdown South and Waterdown Bay houses, draw in air and exhaust through two plastic pipes low on a side wall. Snow is a real factor here. The Hamilton RBG climate station near Waterdown has a 1981-2010 normal of 118.1 cm of snow a year, and it once recorded 38.4 cm in a single January day. A buried or frosted pipe makes the furnace shut itself off for safety. Brush the pipes clear by hand and keep the area around them open, then switch the furnace off and on. If it will not restart, or the pipes keep icing up, book a furnace repair.
Who is allowed to work on a gas furnace or water heater in Ontario?
Under Ontario Regulation 212/01, gas appliances must be installed, serviced and repaired by a registered contractor using qualified gas technicians. The installation has to meet the CSA B149.1 Natural Gas and Propane Installation Code, and the same rules apply to propane. Work is performed by TSSA-certified gas technicians. A proper installation also protects the manufacturer's warranty on the new equipment. Before anyone opens the burner compartment, ask to see their gas technician card, then read how we handle furnace installation and replacement.
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.
I live in a designated heritage house. Can I add a new vent or an outdoor unit?
Possibly, but check first. Waterdown has 121 designated heritage properties, most of them in the old village core, and changes to the outside of the house, such as a new side-wall vent for a high-efficiency furnace or an outdoor air conditioning unit, may need the City of Hamilton's approval. Sometimes a different layout, like running the vent to a side or rear wall, keeps the street face untouched. Contact the City's heritage staff before you commit, then look at the options on our air conditioning installation page.
What decides the cost of a furnace repair?
Mostly the part that failed and the time it takes to find the fault. Cleaning a flame sensor or replacing a worn igniter sits at the small end. An inducer motor, a control board or a blower motor costs more, and a cracked heat exchanger is the expensive one, often the point where a new furnace makes more sense. Age matters too, because parts for older furnaces can be harder to find. You see a written price and approve it before any part goes in. For the full breakdown, read what goes into the price of a furnace repair or a new furnace.
We put in a high-efficiency furnace. Is the old chimney still safe for the water heater?
It needs checking. In the Glenlea, Buchan Court and Renwood Park surveys, many houses started on oil, moved to gas, then got a high-efficiency furnace that vents out the side wall. That leaves the gas water heater venting alone into a chimney sized for far more heat, where flue gases cool, condense and can backdraft into the basement. In the Griffin Survey and the McMonnies and Stock Survey, unlined masonry chimneys can also be damaged by that condensation. Look for soot, rust or moisture around the water heater's draft hood, and if you see any, book a check through furnace installation and replacement.
Why does the house feel so dry in January?
Cold outdoor air holds very little moisture. At the Hamilton RBG station near Waterdown, the 1981-2010 normal daily average is -4.7 °C in January, so the furnace spends months warming dry air. In newer Waterdown South and Waterdown Bay houses, an HRV that is out of balance can bring in more outdoor air than the house needs. In older houses, drafty windows and doors do the same. Static shocks, cracked wood trim and dry throats are the usual signs. Pick up an inexpensive humidity meter, watch the reading for a week, then read our guide to humidity in winter and summer.
