Furnace and AC maintenance in Stoney Creek

Most homeowners book maintenance because something feels slightly off rather than broken. The furnace runs longer than it used to, one bedroom never quite warms up, the blower makes a new hum or rattle, or the system starts and stops every few minutes. In summer the air conditioner may run all afternoon without bringing the house down to the setting, or you may see frost on the copper line near the outdoor unit. A rising gas or hydro bill with no change in habits is another quiet signal. None of these is usually an emergency, but each is easier and less costly to deal with in a tune-up than on the coldest night of the year.

Some things are safe to check yourself. Look at the furnace filter and replace it if it is grey and clogged. Make sure supply registers and return grilles are not blocked by furniture or rugs. Put fresh batteries in the thermostat. Outside, clear leaves and grass clippings from around the air conditioner. What you should leave alone: the burner compartment, the gas valve, wiring, and anything behind a panel held on with screws. If you smell gas, leave the house and call your gas utility from outside.

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. A maintenance visit is a good moment to press the test button on yours.

The Felker, East Felker and Heritage Green areas on the Stoney Creek mountain were built as subdivisions of detached houses and townhouses after the Felker Neighbourhood Plan was adopted in 1989. Most of these homes have a forced-air gas furnace and central air, and many of the original units are now near the end of their life.

On furnaces of this age, technicians commonly find inducer motors with worn bearings, control boards that have started to act up, and heat exchangers showing wear. The air conditioners installed alongside them are often ageing too. A tune-up does not make an old system new, but it tells you which parts are wearing, how urgent each one is, and whether a planned repair now makes more sense than an unplanned one in January. If a heat exchanger shows signs of cracking, the technician will explain plainly what was seen and why the furnace should not keep running that way.

Newer houses in Fruitland and Winona, built under the Fruitland-Winona Secondary Plan, typically have high-efficiency condensing gas furnaces with plastic venting, central air and an HRV or ERV for fresh air. These systems are efficient, but they have their own habits.

A condensing furnace makes water, and that water has to drain. A blocked or frozen condensate line can shut the furnace off, and a tune-up includes clearing and checking that drain. The plastic intake and exhaust pipes on the side wall can be covered by snow, so it is worth knowing where yours are and keeping them clear through the winter. Ventilation units in many of these homes have never been cleaned since the builder left; their filters and cores can be cleaned or replaced during the same visit so the house keeps getting fresh air.

Many furnace and air conditioner manufacturers expect the equipment to be maintained regularly by a qualified person, and some ask for proof if you make a warranty claim. The exact terms vary, so read the warranty card or the owner's manual that came with your unit, or ask us to look at it with you during the visit.

The practical step is simple: keep the written service record from each tune-up with your furnace paperwork. If a covered part fails later, you have dates and notes showing the system was looked after. Registering the equipment with the manufacturer after installation, if that was never done, is also worth checking.

The visit starts with what you have noticed. The technician then works through the furnace: filter, burners and flame, igniter and flame sensor, inducer and blower motors, safety switches, venting and, on high-efficiency units, the condensate drain and trap. Gas appliances in Ontario are serviced to the CSA B149.1 Natural Gas and Propane Installation Code. Work is performed by TSSA-certified gas technicians.

For central air, the technician checks the outdoor coil and fan, electrical connections, the indoor coil and drain, and how well the system is cooling. Work is performed by 313A refrigeration and air conditioning mechanics. If the air conditioner is already not cooling, leaking or tripping a breaker, that becomes an air conditioner repair visit instead.

Before the technician leaves, you hear what was found in plain words. If a part needs replacing, you get a written price to approve first; nothing is fitted without your say. Some rural properties in Stoney Creek, especially above the escarpment, are not on a natural gas main and heat with propane or oil, so please confirm your fuel when you book.

Once a year for the furnace and once a year for the air conditioner is the usual advice. Early autumn suits the furnace, before the first cold week, and spring suits the air conditioner, before the first humid spell. Booking both together in one visit works well for many households. Older systems, or homes where the furnace runs hard through long winters, may benefit from a closer look between seasons.

Changing the filter is the one job you do in between: check it monthly during heavy use. You can request a visit or read more in our frequently asked questions.
