Getting your furnace serviced for winter in London

Professional technicians advise that you shouldn’t wait for the cold weather to start preparing your furnace for the season. Learn more.

Get Your Furnace Ready Before Winter Arrives

When the first cold snap hits London, Ontario, the last thing you want is a furnace that won't start or isn't running safely. That's why professional technicians in furnace repairs and maintenance recommend preparing your heating system well before the temperature drops. A little attention in early fall can prevent breakdowns, lower your energy bills, and give you peace of mind that your home will stay warm and safe all winter long. Here are a few simple checks you can do yourself, along with why professional maintenance remains just as important.

Start with the Air Filter

A clean air filter is one of the easiest ways to keep your furnace running efficiently. Over time, filters collect dust, pet hair, and debris, which restricts airflow and forces your furnace to work harder than it needs to. Check your filter regularly during the heating season and replace it as recommended by the manufacturer, typically every one to three months depending on the filter type and your household. A fresh filter also helps improve the air quality throughout your home.

Use Your Thermostat to Save Energy

A programmable or smart thermostat can make a noticeable difference in your heating costs. Set it to lower the temperature automatically while your family is asleep or when the house is empty during the day, then warm things back up before you wake or return home. You'll stay comfortable when it matters and avoid paying to heat an empty house.

Keep Vents, Ducts, and Exhaust Clear

Your furnace needs a clear path to move air in and out of your home. Inside, make sure supply and return vents aren't blocked by furniture, rugs, or curtains, and have your ductwork cleaned when dust buildup becomes noticeable. Outside, take a walk around your home and check the exhaust and intake vents on the side wall or roof. Items leaning against the house, piled leaves, and especially snow and ice in winter can block these vents, which can cause your furnace to shut down or, in more serious cases, allow exhaust gases such as carbon monoxide to back up into your home. Keeping these areas clear, and making sure you have working carbon monoxide detectors, is an important part of safe furnace operation.

Protect Your Warranty with Professional Service

Most furnace manufacturers offer warranties on parts and equipment, but those warranties often come with conditions. Many require that the unit be installed, serviced, and repaired by licensed technicians, and some require proof of regular maintenance. Skipping professional service could leave you paying out of pocket for a repair that would otherwise have been covered.
